Hi Joern,

Hmm, interesting, though it sounds like you'd need a specialised UHJ 
ambisonic decoder to play it back. That probably narrows the audience 
even further.



unless i'm very much mistaken, UHJ-encoded material can be played back 
on any stereo rig without problems (some even report better stereo width 
and precision). the only drawback i heard about is that UHJ-encoded 
stuff tends to be a little on the ambient site, with a tad too much 
reverb when listened to over stereo...

Hi,

Sure, but you might be disappointed by the results, Pro Logic is not 
very sophisticated (eg. there's no separate rear left and right channel, 
and the bandwidth is limited). Also the only free software 
implementation that I know of is not state of the art, partly due to 
patent problems, and partly due to lack of interest.


There's a LADSPA plugin: 
http://plugin.org.uk/ladspa-swh/docs/ladspa-swh.html#id1401
which does Pro Logic matrix encoding, you will need some other software 
to mix your independent streams into LCR channels (you can do it by ear 
with a 3+ variable send bus mixer), but once you have that you can feed 
it to the plugin and get a pro logic compatible stream out.


PS ignore the documentation, it has been tested, and it does work, just 
not brilliantly. You will get better results if you EQ the mics a bit to 
cut the level of the highs and lows a bit, especially in the rear channel.


You would get much better results with an ambisonic stream, but I don't 
/think/ you can make stereo-compatible ambisonic streams, and not many 
people have ambisonic decoders. Other people on this list know a lot 
more about ambisonics though.


i'm very new to ambisonics, so i may be wrong, but i think there are 
indeed stereo compatible first-order ambisonics streams. iirc, the 
format is called UHJ, and it matrixes WXY (lossily) into L/R (i.e. no 
height information).


i've changed the subject to bait fons :-D
if we're lucky he knows an implementation of 2-channel UHJ.

i found this article: http://www.ambisonic.net/ambi_AM91.html
but it does not give details as to how the matrix encoding is accomplished.

Re: [linux-audio-dev] Hunt for old list archives.

[Joern Nettingsmeier]

kai, do you still have copies of the old archive, or have they all been 
migrated to ccrma?

Hi all,

As discussed previously on this list, we are getting ready for a
migration of the three LA* lists to linuxaudio.org.

Many things are done to make our list better. One of them concerns
archives. As you may have noted, LA* archives found on
music.columbia.edu date back to 2002. Ico told me that there used to
be an LA list hosted somewhere else way before that (1998).

Having to do this migration, we will also migrate our archives. If
possible it would be cool to be able to merge also the older archives
in the whole.

The question is, do some of you have any idea where I could find these
archives, if they still exit...

[linux-audio-dev] [admin] maintainership passes on...

[Joern Nettingsmeier]

hi everyone!


i'm very happy to announce that marc-olivier barre will be maintaining 
the linux-audio-* lists from now on.


let me take this opportunity to ask for a few more volunteers to 
moderate linux-audio-announce. get this: for years, brilliant minds like 
ingo molnar, robert love and lee revellhave been toiling with the kernel 
for a few measly microseconds gain - as a linux-audio-announce 
moderator, you can cut latencies by hours if not days. how is that for a 
claim to fame? please get in touch with marc-olivier.


it's been a pleasure to participate in this linux audio community for 
all those years, and i have profited immensely from the great work done 
here! thanks everyone, and i hope to see you around at LAC 2007!



best wishes,

jörn

since there hasn't been any further discussion, i'm wrapping up the

marc-olivier barre is volunteering to take over the job of list

ico suggests to move the lists to linuxaudio.org.
i like both ideas :)

marc, if your offer still stands, please get in touch with me via 
private mail and send me an ssh key to grant you access to the list 
server account. (i will have to check with the site admin before 
installing it, but i'm sure there will be no objections.)


to the others: i think it would be good to have another two list 
moderators for linux-audio-announce, in case people ever want to go on

if you think about taking on the job: we have 3 lists,

for admin tasks, and there is a neat web interface for common admin

[linux-audio-dev] [admin] spam handling on the linux-audio-* lists

[Joern Nettingsmeier]

hi everyone!


just fyi, the amount of spam in the moderation queues has risen to such 
an extent that the server admin, douglas repetto of columbia university, 
has implemented an auto-clear function for the queues.


that means: if your message is not forwarded to the list, it will be 
dead, gone and forgotten. this happens either if you are using a 
non-subscribed address to post (regardless of whether you are subscribed 
with another account, even if it's in the same domain, i.e. if 
[EMAIL PROTECTED] is legitimate, [EMAIL PROTECTED] will bounce), or if 
mailman determines you are posting html.


due to a misunderstanding, this auto-nuking has been active on 
linux-audio-announce as well for the past couple of days. so if you 
tried to get an announcement out, please resend - the old one went 
straight to the bit bucket.



regards,

jörn

[linux-audio-dev] LAC 2006 Live Streams

[Joern Nettingsmeier]

hi *!


the linux audio conference 2006, which takes place at the zkm in
karlsruhe/germany from april 27 to april 30, will be streamed live for
your convenience, inspiration and enjoyment.

all presentations (which are listed on
http://lac.zkm.de/2006/program.shtml) are covered as ogg vorbis audio
streams in two bitrates (one for modem users and one for
slightly-more-broadband users) and ogg theora/vorbis a/v streams (for
broadband users only). to watch and/or listen, you can use a recent
version of mplayer, vlc or curl | theora123, if you prefer.

the stream urls are listed at
http://lac.zkm.de/2006/streaming.shtml. we will start test streams
tomorrow by 12:00 utc+2. as always, there will be chat channels to go
with the streams, where you can report problems, discuss the
presentations and also ask questions which will be relayed to the live
audience by the local chat operators here at zkm.
these channels are #lac2006 for general issues and chitchat, and
#lac2006-track1 and #lac2006-track2 for questions and remarks about the
current presentation, all on irc.freenode.net.

you will be able to download the presentation slides in advance to read
along as you listen and watch. the quality of the video streams will not
be sufficient to read the projections, but you should easily be able to
make out which slide is currently up.


on behalf of eric rzewnicki (who did most of the streaming work this
year) and the rest of the lac organizational team i wish you lots of fun
with the streams. kudos again to the icecast team, especially to karl
heyes, all the folks at xiph.org who brought us all those great free
multimedia codecs, and the crew here at zkm for their great support and
cooperation!

[linux-audio-dev] [admin] reminder: no html postings on linux-audio-*

[Joern Nettingsmeier]

hi everyone!


just a quick heads-up: html postings or other "enriched" atrocities are 
banned on linux-audio-*. unfortunately, the mailman response "message 
has a suspicious header" is less than helpful. if you see your postings 
bounce with this error, in 99 of 100 cases you are trying to send either 
html or binary attachments.


this warning applies especially to our friends at gmail.com / 
googlemail.com. their web interface seems to send out dodgy mails by 
default.

[linux-audio-dev] any news concerning the lad site?

[Joern Nettingsmeier]

hi paul, benno, everybody!


tried to reach you in private, but haven't heard anything back so far.
the lad site has been offline for quite a while now, and i find the
entire issue pretty frustrating... it's not exactly what i would call
"high availability". :(

i'd just write the whole site off if it weren't for the fact that i used 
to be listed as webmaster and people keep writing to me complaining 
about broken links.


please, someone step up and do something about it.


jörn



hi paul, hi benno!


how's the linuxaudiodev.org migration going? it's been offline for
quite a while now, breaking a whole lot of links all over the place.

benno, why did you remove the stuff before the new location is set
up? and why did you never contact me about the bandwidth usage
problem before? we might have been able to find a less-hurried
solution than taking the entire material offline for a month. i
really appreciate lionstracs' bandwidth donation, but with a little
bit more communication, things would have been a lot less painful.

can i again ask you again to maintain the
www.linuxdj.com/audio/lad/.* redirction to linuxaudiodev.org/{1}? i
know the site is crap and unmaintained, but we have worked hard to
establish it as a repository of audio-related material, and it's
quite good for that. i'd hate to see it fall into google oblivion due
to ever-changing urls.

paul, it looks like the lac 2006 will again generate metric shitloads
of material - is there some room on your iron for another 10gigs of
videos and audio dumps? if so, how can we organize the upload? i can
put them somewhere at zkm, or you can give me a way to push them up
myself.


best,

jörn


ps: in case any data went into the bit bucket, i have a fairly
up-to-date local mirror. not quite the latest, because my account was
de-activated without notice, but still usable.

finally chiming in...

glad there's so many volunteers for site hosting. it's time that the 
site moves on, it's been without maintenance for over a year now.


please make sure that the redirect from http://linuxdj.com/audio/lad/ is 
maintained, since hundreds of sites worldwide use that url.


also, the linuxaudiodev.org domain has expired a while ago, it would be 
nice if someone were to reclaim it and point it to the new location as 
well. (benno, i've been trying to contact you about this for months, but 
you're a little hard to reach these days.)


if whoever is going to re-do the site is interested in real-time list 
stats (a crude version of which you can see on the old subscribe.php 
page, unfortunately very out of date since i've been locked out of the 
machine for the better part of a year), get in touch with me and we'll 
set something up.

I'll wait for Paul's reply how to proceed (redirect linuxdj.com etc).

[linux-audio-dev] [admin] music.columbia.edu server downtime

[Joern Nettingsmeier]

hi everyone!


a happy new year to all folks on the gregorian calendar, and a generic 
happy next 365 days to everyone else!


the music department at columbia university are taking the list server 
down for an upgrade on the coming weekend, so expect interruptions for 
linux-audio-dev, linux-audio-user and linux-audio-announce. you will 
probably want to keep a copy of all the mails you send over the weekend, 
so that you can re-send them in case they end up in the bit bucket.


let me take this opportunity to thank douglas irving repetto for many 
years of painless hosting and friendly help, and the entire music dept. 
for their generous donation of iron and bandwidth. kudos, guys!


rumor has it that the new list server will be an os x machine. hopefully 
this will make the lists even more user-friendly and aesthetically 
pleasing than before ;)



all the best,

Hello,

We will be upgrading the music.columbia.edu server this weekend.
Hopefully all of the work will be done on Saturday, but it may extend
into Sunday. music.columbia.edu will not be available during the
downtime. That means no websites will be served, no email will be
sent/delivered, no mailing lists will function, etc.

I'll send an update later this week with info about some changes that
you'll see on the new server.


Happy new year,

[linux-audio-dev] [admin] attention gmail users: please fix your message format!

[Joern Nettingsmeier]

hi everyone!


lately there are a number of gmail users filling up the moderation 
queues with "message has a suspicious header" bounces.


this is almost always due to people trying to send non-text/plain 
content, which for a number of very good reasons is banned on linux-audio-*.


it seems that gmail has an unfortunate default setting that some people 
are not aware of... gmail users, please fix your settings!

I hope readers of LAD might find the following useful, and I wonder if
you'd mind posting it for me. Linux audio developers have been
interested in these posts in the past.

Please note that my understanding of employment legislation is that we
are unable to employ personnel from outwith the European Union unless
it can be demonstrated that the required skill set does not exist
within the EU (which in this case it certainly does)

Here's the post...

the conference takes place from april 21 - 24, with lectures and
workshops from 11:00 to 18:00 UTC+2 every day and concerts in the evenings.
i would like to invite you to join us, either in person (attendance to
the conference is free) or remotely over the internet.
for remote participants of the conference, there is a chat room #lac2005
on irc.freenode.net. a chat operator will be present in the auditorium
in karlsruhe and will relay your questions to the lecturer and the local
audience. papers and slides will be made available for download in
advance if possible.
information about the streams and how to watch them is at
http://lac2005.zkm.de.
huge kudos to the icecast, ogg, vorbis and theora developers and
communites for their code and expertise!

kind regards,

[linux-audio-dev] [admin] new policy and moderators needed

[Joern Nettingsmeier]

hi everyone!
after reading the thread "Other real-time options", it occurred to me 
that the strict members-only policy of this list has one huge drawback:

it makes communicating with lkml and other communities almost
impossible, since cross-posted threads will not make it to this list.
i would like to change this.
however, i'm very glad that the linux-audio lists are almost 100% 
spam-free, and i would hate to see that change.

so here a proposal for a new policy: cross-posted messages from other 
mailing lists should be hand-approved in a timely fashion, and known 
individuals working in audio-related fields get added to the illustrious 
"auto-approve" list.

unfortunately, my time is limited, so i would like to find five or so 
people who would be willing to step up as moderators. everybody raise 
your hands and say YEAH!.

if you like this idea, we should then approach the key people on lkml 
(currently akpm, mingo and con) to always cross-post latency-related 
stuff to linux-audio-dev.
this has two advantages:
 * the burden no longer rests with the few fearless individuals who 
keep preaching on lkml (kudos to paul, jack and lee ;) - everyone can 
chime in.
 * it will give the kernel preemption guys more testers and better 
feedback.

please comment,
jörn

that's because the stream is not continuous yet. so the client stops

this will change as soon as we use a real stream source and not files.

our master server is currently open for public testing at
http://lac2005.zkm.de:8000. in order to conserve bandwidth, the number

there is one video (un chien andalou by salvador dali) and one audio
stream (the jazz tune "melancia" played by a friend of mine) streamed in
two different bitrates each.
please test them (especially the video stream). since theora streaming
is quite bleeding-edge, few distros will support it out-of-the-box.
in order to generate some documentation for stream users, we have 
borrowed frank barknechts wiki, please go to

http://footils.org/cms/pydiddy/wiki/LinuxAudioConference2005
and add hints for your own distro.
! note that after this initial test period, the master server will be
closed to the public again. during the conference, only relays will be
given access. you can tune to one of the relays instead. urls will be
posted real soon now.
anticipating some bug reports:
* yes, the video is black-and-white.
* yes, there is some (intentional) distortion in the audio stream.
* yes, there is currently no metadata displayed.
* yes, the streams are not continous, i.e. your player will quit after
  the  piece ends.
* yes, you will see greenish garbage at the beginning. that's your
  player waiting for a theora keyframe.
like last year, there will be irc channels:
  #lac2005 @ irc.freenode.net for general conference issues and feedback
 from remote conference participants
  #lac2005-tech @ irc.freenode.net for stream-related technical issues
if you have problems or success stories, share them on the lists or on irc.

[linux-audio-dev] LAC 2005 streaming: CfP

[Joern Nettingsmeier]

hello everyone !
the linux audio conference 2005 @ zkm (http://lac.zkm.de) is drawing 
near, and it's time to get the streaming network up and running again.

like last year, the idea is to stream all the lectures and discussions 
live over the net, and to provide webcams with either stills every 30 
secs or (if we can pull it off) theora video streaming. of course we 
will also provide IRC channels for online participation.

currently, i'm looking for people who are willing to host a streaming 
relay server based on icecast2.
for our primary relays, we will need servers with >= 10 mbits of 
bandwidth (smaller links would put too much load on the master server),
however, folks with less bandwidth are welcome to join in as well, but 
they will have to pull their streams off a secondary server.

if you can donate some time and bandwidth and want to have fun with live 
streaming, please holler now. please also indicate whether you would be 
willing to participate in a sort of "stand-by streaming network" that 
could easily reactivated for other linux-audio-related events (i'm 
cc:ing tim hall who is putting together a conference in the uk later 
this year, and maybe conrad could use it too for the linux audio 
miniconf in australia...)

also on the  cc: list are some of the folks who participated last year 
(hi marco, patrice and fred!), in the hope that they will be able to 
join us again...

we will prepare detailed instructions on how to build and configure 
icecast2 - previous streaming experience is not necessary, although it 
helps if you know your way around basic networking issues.

if you are interested, please reply to my private address only, so that 
we don't clutter people's inboxes too much. then i'll put together an 
ad-hoc cc: list or maybe we'll ask for a proper mailing list on the zkm 
server, depending on how many people are interested...

i don't have francois dechelle's current email address, perhaps someone 
could forward this mail to him.

for a very simple one try the matrix_spatializer in swh-plugins.
it converts an xy stereo signal into ms and lets you adjust the m/s

[linux-audio-dev] [admin] announce-list policy rationale

[Joern Nettingsmeier]

Florin Andrei wrote:
On Sun, 2004-12-12 at 13:58 +0200, Kai Vehmanen wrote:
when linux-audio-announce was created, it was agreed that
announcements should be crossposted to all three lists. The
reasoning was that this way people wouldn't have to subcsribe to
LAA if they were already on LAD+LAU.
Now when you look at LAA archives, some people post only to LAA,
some (like me) to all three lists, and some to either LAA+LAD or
LAA+LAU.

I didn't even knew that LAA existed. :-/
Perhaps Mailman should be configured so that it adds a footer to each
 message, containing basic stuff such as where to go to 
subscribe/unsubscribe, and where are the other related lists.

Anyway, i think your proposal makes sense. Crosspostings are bad. Ok,
 now let me subscribe real quick now to LAA...
sorry, i'm horribly behind LA mail :(
the original rationale of the cross-posting policy was as follows:
* linux-audio-announce should have no discussions at all to keep the
volume down (so that nobody would be discouraged from subscribing).
* announcements tend to spawn interesting discussions
* these discussions should be in some way related to the announcements,
for example by being in the same mail thread.
that's why announcers are encouraged to cc: lad and lau, so that
discussions can follow.
since some people choose not to do that, folks interested in seeing all
the announcements should probably subscribe to linux-audio-announce as 
well.

[linux-audio-dev] arts development discontinued...

[Joern Nettingsmeier]

hi everyone!

i just read dave's latest musings and stumbled upon stefan westerfeld's 
notice that he is no longer maintaining arts.

many of you have probably already read about it. however, if you want to 
 see a really graceful and stylish way of abandoning a project and 
changing one's mind, here are stefan's remarks:

http://www.arts-project.org/doc/arts-maintenance.html
even though arts will probably become obsolete in the near future, i 
think it should be pointed out that just like the often-bashed open 
sound system it has been a crucial step in bringing linux audio to the 
mainstream, and the community owes much to stefan in that respect (not 
to mention his many contributions to ladspa and other projects).

at a time when there was hardly anything else than esound, stefan 
tackled the job of giving desktop users what they want: multiple source 
playback and an elegant user interface.
even though arts turned out not to be feasible for high-end applications 
(a fact that stefan now acknowledges, contrary to his former "mission" 
;), it has certainly increased the momentum behind linux audio a great 
deal.

kudos, stefan.

device. It was probably this very one that was aunting you before. After
some attention and furious alsa-bugtracker exchange, Karten Wiese has been
able to solve this, even tought he's got no OHCI hardware near him.
I was watching that thread a little, because my symptoms were
very similar. Strangely, though, I have a UHCI based card, so I'm
not sure why I was seeing similar symtoms.

Then Karsten did it again. He crafted a special jackd alsa/usx2y backend
which enabled the so-called raw-usb mode of operation. And it was just
yesterday I have proposed the merge into the official alsa backend driver
on the jackit-devel list. With this new experimental stuff, one can run
jackd in realtime with pretty lowest-latency parameters, without aural
artifacts (i.e. crackling). AFAICT this is a greatest breakthrough on the
USB audio arena, so I would think twice about getting rid of your US428 ;)
I'm having a bit of trouble with the usx2y backend to jackd. I
bastardized the jackd-us2xy rpm to make a nice deb file, but
jackd still says "unknown driver 'usx2y'". Even downloading and
compiling the source, and running it directly from the directory
it ws compiled into. And does it automatically use the rawusb
interface? What's the advantage of using the usx2y driver as
opposed to the alsa driver?

So my recipe goes like this:
1. Have REALTIME_PREEMPT on the kernel config.
2. Make sure you have loaded the latest snd-usb-usx2y>=0.8.7.1 (as of
  latest alsa-kernel cvs).
3. Tune the RT priorities (SCHED_FIFO) of the time-audio critical IRQ
  threads:
90 - timer (IRQ 0)
80 - rtc (IRQ 8)
70 - snd (or whatever your PCI soundcard will hook, usually IRQ 5)
60 - usb (ohci_hcd or uhici_hcd, usually IRQ 10)
  You should have schedutils installed (chrt) for this exercise.
4. Load the snd-usb-usx2y with the nrpacks parameter set for:
  a. high-stability: nrpacks=4
  b. low-latency:nrpacks=1
  Anyway, be advised that you can only run the forementioned "rawusb"
  mode if you set on this later one (modprobe snd-usb-usx2y nrpacks=1).
Run your jackd command line (or qjackctl;) as usual, but given the above
priority tunning, you should try e.g. jackd -R -P60 ...
Thanks a lot for this detailed info! I recompiled the newest
snd-usb-usx2y driver, but how do I tune RT priorities? I got the
schedutils package, but I'm having trouble finding details on how
to use chrt.
Thanks again for the info.

Hello,

that I'm not going to take the existing archives offline, so all links

good.
Fortunately we nowadays have many other archives of the lists. We just now
need to pick a new official archive and update the links at:
http://www.linuxdj.com/audio/lad/archive.php3
I propose that we use the archives at columbia.edu:

http://www.music.columbia.edu/pipermail/linux-audio-dev/
... and so on.
that won't really cut it, since they are not (yet) searchable, and 
they lack the really old messages that went through 
ginette.umontreal.ca way back when

douglas, do you think we could set up a htdig engine on 
roar.music.columbia.edu (all lists would benefit from that)?

i hope i don't overstretch columbia.edu's hospitality at some point
if that's not possible, let me know and we'll find something else.
Very good archives can also be found at gmane.org:
http://gmane.org/info.php?group=gmane.linux.audio.devel

same problem regarding the old messages.
kai, i will keep looking for an alternative location, and i may need 
to mirror the eca.cx archives at some time

any service that uses the portmapper is limited to single subnets in

some might remember that two years ago (or so) there was a nice (though at

Juno 6, a faith reproduction of the Roland Juno 6. At some point this project
disappeared from the websites. When I talked to Marek Peteraj earlier this
year, he mentioned to me that he attempts to convince the developers to release
it to the public. And right now, while "proofreading" Ico's paper
for the next ICMC I found that it has been open-sourced this year and is
now available here: http://sf.net/projects/juno6
That's the old source code from 2000, and people have started converting it
into a VST instrument recently.
I just wonder if anyone has already begun with attempts to e.g. jackify it
or otherwise fixing it up for e.g. ALSA Midi input etc. Looks like a very
nice small to medium-sized project..

But do you know about the functionality of package "java.lang.ref"? The

Provides reference-object classes, which support a limited degree of

the latter object may still be reclaimed by the collector. A program 
may also arrange to be notified some time after the collector has 
determined that the reachability of a given object has changed. 
i think the question is, how do you program real-time applications 
in java? you'd need to switch off the garbage collector entirely 
when the real-time thread runs, and only activate it when the system 
has cycles to spare. how do you do that?

Hi Alfons!
I went to ambisonic and read the FAQ. I do not agree with them when they

It is possible by using phase differences (and the assumption that
people are not living in sound-dead laboratories) to project sounds
outside of the stereo-field.
I did not find anything either to support that 4-channel is superior to
7-channel ... Maybe I was not looking hard enough ??
/jens
not superior, but equivalent, less snake-oil-infested, cheaper, more 
general and more elegant. ahem, yes, superior :-D

you can express any spatial sound with just 4 channels, where one is 
the mono component, and 3 are the x, y, and z-axis difference 
signals (similar to m/s stereo).
you can then render it to any speaker layout you want.

imnsho all those n.1 surround techniques (where n is defined as the 
number of speakers you have or want to afford plus any positive 
integer greater than one) are money-making schemes. anything above 
5.1 in one plane is plain stupid (even the center is not necessary 
in theory, although it makes the job for the mix engineer a lot easier).
and the mutually incompatible encoding formats are not helping either...

and as to encoding anything outside the line between the speakers in 
stereo, well, it just does not work very well. it's ok for the 
occasional "wow, cool" effect, but for not much else. all those 
nifty little tricks have very small sweet spots and fall apart as 
soon as you move just a little, and those oh-so-cool 3d phasing 
effects completely and utterly wreck the low end in practice.

imho, xml *is* very human-readable if the DTD is sane and the output

so ++xml.

[linux-audio-dev] [ANN] Linux Audio Conference #2 live streams, cams and chat available tomorrow

[Joern Nettingsmeier]

hi everyone!


for those who have not heard it yet, the second international Linux Audio
Conference is taking place at the ZKM Karlsruhe/Germany from 29.4. to
2.5.2004. see http://www.zkm.de/lad/ for details.

we have a number of very interesting presentations, all of which
will be streamed out live, for the unlucky folks who can't be here in
person. additionally, you will be able to download the presentation slides
in advance should you wish to follow a lecture.
there will be feedback  channels on IRC, operated by folks who are in the
lecture rooms. they will relay questions from you to the live audience.
if all goes well, webcams will upload still images every 30 seconds to
give you an idea of the ambience and of which slide is currently up.

all important information on streaming relays, downloadable material, irc
channels etc. will be dumped to

http://linuxaudiodev.org/eventszkm2004.php3 .

this page will be updated very frequently during the next days.
the streams won't be up until tomorrow morning, but the chat rooms are
already there.

please forward this mail to any interested people. and no, we do not
fear the slashdot effect :)


enjoy,

joern

Re: [linux-audio-dev] Re: [linux-audio-user] laconf2 call for help w/ irc and streaming

[Joern Nettingsmeier]

probably. we will start with #lad on irc.freenode.org, and create 
ad-hoc channels for the three venues. additionally, chat ops and 
stream relay ops will internally communicate via another channel.

those rooms will be listed on a yet-to-be-written website that will 
also list the stream and webcam relays as well as provide links to 
papers and slides.

hi everyone!

as you will certainly have heard, we are getting closer to the 2nd 
linux audio conference at zkm (http://www.zkm.de/lad).

as you might also have heard, we will have live streams of all talks 
and lectures in ogg format for those who can't make it there in person.

last year, we had an irc "feedback channel", meaning i would sit in 
the lecture room with a notebook, answer questions from people who 
were listening to the stream and relay their questions to the 
audience if necessary. i want to do the same this year.

problem is: there are three lecture rooms now.
so i'm looking for a couple of people who'd be willing to help out.
specifically, i need people who

* are at the conference :) preferably the whole time
* bring their own laptop with working sound output and headphones
* have some experience with networking
* have or can operate a webcam on their machine and are willing to 
install xawtv
* like to chat

your tasks will be:

* to attend talks
* to have an irc window open and answer and relay questions
* to set up a webcam that will provide the listeners with stills so 
that they'll know which slide is up atm etc.
* to monitor the outgoing stream and to ping the relays from time to 
time.

the more helpers, the less work for all of us. last year, it has 
been great fun, although chatting, monitoring (with some 5 seconds 
lag) and listening at the same time can make your head spin in funny 
ways.

please cc: me privately on any replies. thanks.

Re: [linux-audio-dev] how about a LADSPA BOF session at LAConf#2 ?

frank, matthias, could you perhaps just decide on a date, and 
announce it on the zkm website as a non-public (i.e. not for casual 
passers-by, but of course free for all interested developers)?

i like the morning option, too, but not sunday, since there's 
already a panel discussion in the afternoon.
i'd vote for friday, 10:00, so that if something useful comes up, 
there's the option to agree on a "dinner session" later to continue 
the debate.

majority vote :)
I personally would favor the morning option because the time limit

[linux-audio-dev] how about a LADSPA BOF session at LAConf#2 ?

[Joern Nettingsmeier]

hi richard, hi everyone!

i'm just wading through 2k5 linux audio mails, as i'm a little 
behind on current affairs due to a lengthy and less-than-smooth 
moving of houses.

after reading the LADSPA related threads of about a month ago,  a 
couple of things became obvious to me:

* LADSPA has some showstopper deficiencies to some developers

* there seems to be an ongoing battle about how essential rdf 
metadata support should be: if it's purely optional, then many 
things that conceptually should be metadata must be duplicated in 
more or less inelegant additions to ladspa.h, and there seems to be 
no real consensus on how to do that. if metadata support is 
necessary even for simple hosts to create usable guis, we put the 
famed 'S' in danger.

* at present, the discussion has reached the "matter of taste" point 
and is pretty much dead in the water.

* with no real formal process for the development of LADSPA except 
for richard's role as the "benevolent dictator", and richard being 
very quiet on the matter, those developers who opt for an extension 
of the spec may feel there is no way to get their proposals through.

* maybe for that reason, there has been some imho ill-advised 
rhetoric towards fait-accompli tactics.

now wherever LADSPA is heading, one thing is very certain for me: 
LADSPA and JACK are the very two projects that absolutely *MUST* 
*NOT* *FORK* or even develop "local dialects" at this point in time.

i'm not afraid of forks in almost all contexts, but a forked 
"common" api is a dead api. whatever happens, let's not jeopardize 
the two major kickass components of linux audio.
there may come a time when LADSPA has become so inert and obsolete 
that we should take care of it the darwin way, but this time is 
still a long way off.

for that reason, let's try to cram a LADSPA BOF into the already 
overflowing schedule at LAConf#2, or at least dedicate a "working 
dinner" to the future of LADSPA.
i have this feeling that injecting the face-to-face factor and some 
german beer into the discussion might remove some obstacles. :-D

richard, if you are reading this, some comment from your part would 
also be helpful imho. i found you have not participated in the 
ladspa discussions since release 1.1, which was in august 2002.
it seems everyone still considers you the keeper of LADSPA, and it 
might clarify things if you stated

* your opinion on the current discussion;
* your criteria for approving extensions;
* whether you are willing and have the time to retain the role of 
official LADSPA maintainer and to have the final say over what goes 
in or what doesn't, or let go of this role;
* whether you can make it to LAConf#2 for a beer :)

all the best,

jörn

Writing a guitar sound synthesizer that sounds good is a very

Yeah, that was my first thought.

Another approach would be to record the unprocessed guitar sound, 
compress/resynthesize that one way or another (plain audio, mp3, 
custom tuned compression algos, resynthesis using using physical 
modelling etc in increasing order of difficulty), and then apply 
guitar FX and speaker emulator plugins on the result. I think the 
most important part is to preserve the subtle details from the real 
guitar sound, as the lack of realism in the playing technique is what 
kills most synthesized guitars I've heard so far.


Tricky. To get crunchy hard-rock guitar sounds like Pete's
(nice track pete!), you'll have to realistically emulate palm-muting,

Handles of some sort to create segmented patch cords would be nice. As would 
the ability to rotate a client box over 90 degrees, so you have the

Another feature could be symbolic link objects. Sometimes you have a signal 
detour to some part of an app that is  somewhere else on the graph and 
allready heavilly connected to all kinds of other stuff. A symbolic-link to 
foo:input12 foo:output12 could be nice then. 


Whew, now this is getting complicated. :) These things are nice in
modular synths, but wouldn't it be overkill in a patch bay?
hmm. i don't like this symlink idea. kinda kludgy to me, but that's 
surely a matter of taste.
how about a feature to collapse an arbitrary part of the graph into 
a black box? rubber-band a couple of jack clients, press 
ctrl-something and you get a blackbox with all inputs that 
originally went into the subgraph and all outs as well, which is 
labelled by default with a simple list of the clients inside, 
regardless of their ordering.

just an idea...

i'm willing to take care of the streaming like last year. this time, i'll
try to provide a webcam as well, but i'm not yet sure about streaming
video. but a picture every 15 secs or so should be possible. ;)
my plan is to have an ogg stream of the talks and the concerts, an irc
talkback channel, a website with the presentation material for download
and a crude webcam to give you an idea which slide the presenter is
talking about atm.

work to set up a relay network for streaming will begin by the end of
february, i've got a couple other things to do atm.

[call for mirrors]

if you have a host with good internet connection and are willing to donate
some bandwidth, please contact me off-list. either you provide an icecast2
server yourself, or else i will need shell access to build one (though not
root). the distribution needs to be recent, or else building icecast2 is
problematic.
for the webcam, we'll need a couple http servers as well.
i thought about round-robin dns, but a friend just pointed out a master
server with some php code that will produce a different link each time it
is called is probably easier.
so all you have to do is pull an image every couple seconds, make it
available somewhere and send me the url.

this is a somewhat heated reply, you may want to skip it entirely if you

but since my own efforts are being drawn into the argument now, i feel 
it's time to sound off:

Suddenly you're now speaking as the representative of the whole Linux

representatives of the Linux Audio community are the Linux Audio
Developers.
marek, please: it's time to shut up.

i too have been speaking as a representative of the linux audio 
community on various occasions. frank neumann has even been so bold as 
to organize a trade show booth in the name of the linux audio community. 
matthias nagorni is just now and in front of everyone's eyes committing 
the heinous atrocity of organizing a conference in the name of the linux 
audio community.
none of us has obtained anyone's mandate, none of us has discussed 
everything we do on this list up to the point of consensus.

SO WHAT?

there is no such thing as a linux audio community, except for *what 
people do*. so daniel is as much part of it as you and i.
this list is just a list. a means of communication. it's great at times, 
and sometimes it's not. as pointed out before, not even everyone 
interested in linux audio uses it.

nowhere on the whole wide web will you find a clear definition of what 
the linux audio community is and who can speak for it. and you are not 
going to define it either by continous nit-picking at the efforts of others.

linux audio is what people do with it. that's what free software 
communities are about. if somebody tries to put an organisation together 
to provide a new forum for exchange with (shudder ;) commercial 
developers, that can only enrich the community. if it works, great, if 
it fails, so what?
nobody is going to take all the code away from you (thanks to the gpl - 
chapeau, mr. stallman!), nobody is going to take all the contributors of 
the community away. where is the problem?

there have been some valid points of criticism on how david is 
organizing and presenting his effort. i'm sure these can and should be 
discussed. but there is absolutely and utterly no point in bashing 
peoples' heads in for working free-of-charge towards what they believe 
will be for the good of linux audio.
be pragmatic: if the linuxaudio.org effort is worth crap, then it's 
going to die a good and honest open-source death. if it prospers, then 
it will add another facet to the linux audio community. but how could it 
really endanger or take away anything that the community already has?

the only thing i see endangered here is the atmosphere of mutual respect 
that has been one of the pillars of this mailing list.

if you fear fragmentation of the community, well, that too is part of 
the game. projects are forked, forks are healed, projects succeed and 
die, communities form and disperse themselves. no harm in voicing your 
fear of fragmentation, but why attack people and discredit their efforts?

excuse me for ranting, but i too have invested a lot of free time *and* 
money to advocate linux audio and the linux audio community. i want to 
continue to do this *as i see fit*, to the best of my knowledge, and i 
certainly do not want to face a stupid public tribunal such as this in 
return for my efforts.

in my view, david first of all deserves a huge cheer for a new idea and 
a lot of work, and then we can discuss the points that were subject to 
criticism.

this whole thread sadly reminds me again of the zynaddsubfx flamewar 
about the weird jesus clause its author had on his website. well, above 
all, imnsho, if some new thing comes with strings attached that do not 
suit you, just ignore it. you haven't lost anything, and nothing is 
being taken away from you. it's an offer, after all.


on the basis that we will be offering free advice and 
information rather than a sales pitch. The organisers have agreed to 
give us the stand at cost, which they didn't have to do.


So how is that different from LinuxTag or ZKM? Again, what are we trying
to promote? The only thing we should promote right now are the Linux
Audio applications. Companies have resources to promote themselves. And
it makes no sense to promote Linux Audio Users at such event.
The problem is - Frank, Joern, Matthias were doing a great job
organising events and helping the Linux Audio Developers to promote
their open source Linux Audio applications. They never called themselves
the directors of LAD.
nor does david. he stepped in as director of linuxaudio.org to get a 
ball rolling. just as matthias and frank "usurped" the role of 
conference organizers. *to*get*something*done* !

if you consider some of his actions bad style, then fine, but show some 
style yourself when off

i suggest to expand it to "JACK and Alsa Sequencer Snapshot" instead, to

apart from the joke value, i think it's nice to either name it something

hello everyone!

there are a number of messages from LAD contributors who are not

my current policy is to reject them, which i hate to do, because they

the problem is:
i don't have the time to check whether the poster has re-sent them 
already using another (subscribed) account, and if i just accept all 
postings whose senders i recognize, there will be duplicate messages.

so please, LAD patrons: do subscribe to LAU. you can disable mail 
delivery if you want to reduce the load on your inbox, but you will be 
able to crosspost.

unfortunately, there is no feature in mailman to allow all LAD 
subscribers to post to LAU, or i'd use it.

[linux-audio-dev] OT: spam

[Joern Nettingsmeier]

hi *!

after getting about 20 spam/day to linux-audio* from a single taiwanese 
domain, i filed a complaint with their postmaster and abuse addresses.

i thought i'd share this laugh with you:

FUCKWITS! THIS IS THE FRIGGIN POSTMASTER ADDRESS! sigh. if taiwan 
doesn't do something about their email legislation, they will find the 
entire country in a mail blackhole soon.

why is every moron allowed to run an internet server just so, and

[linux-audio-dev] [Fwd: [linux-audio-user] 3-D Audio: To Plug-In or Not to Plug-In?]

here's a post from david clark to the lau list, which i think might be 
developer material :)

it's a followup to this thread:

Reply-To: [EMAIL PROTECTED],   A list for linux audio users

To: [EMAIL PROTECTED]

On the 3-D audio (Interest in Software?) thread, I had promised to mail
out something on a plug-in.  It got a little too long, so rather than
clog up everyone's mailbox, I went ahead and put it in:
http://home.earthlink.net/~davidrclark/linux_audio_users/Plug-in.html

If this isn't proper nettiquette for this user's mailing list, someone
please do let me know.  It would be easier just to email my ramblings.
-

Bottom line is: I'm not sure if it makes sense as a plug-in or not.
I think I may provide the impulse response function generator and my
own convolution engine, then let one of the plug-in gurus see what they
can do, if they want to.  If nothing happens, it'll be a command-line
thingy until I get motivated to GUI it all up.
No schedule, but I'd be happy to provide a crude tarball to anyone who
wants to try and deal with it at any time.  I PROMISE it won't be easy
without some instruction.  Please email me privately also so that I'm
sure to see it.
Thanks,
Dave.

does anyone have any clues about how to solve this in a "packageful" way?

i found my version of fftw built all kinds of libs like *rfftw* and

went away...

Many thanks to Dave for this fine article.  He's done more than anyone
to make Linux Audio accessible to a wide group of users.
One question.  Dave states (about linux-audio-announce)...

  Posts to this list often and sometimes annoyingly are cross-posted
  to LAD and LAU, but hopefully it will become the preferred list for
  letting the public know about new and updated releases.
I thought from several previous discussions that cross-posting of
announcements was *encouraged*, so that LAU and LAD readers need not
subscribe to LAA.  Did I misunderstand this?  Dave's point
(announcements only on LAA) actually makes more sense, but I
understood the list policy differently.
Is there an official answer to this FAQ somewhere?
quoting the lad subscrioption page:

"You are highly encouraged to cc: release announcements to the announce 
and user lists at

[EMAIL PROTECTED] and
[EMAIL PROTECTED]"
quoting the laa subscription page:

"[...] if you require public feedback or discussion, please cc: the 
linux-audio-user list or other appropriate forums."

could be worded a bit more precisely, i agree. iirc the consensus was 
that most patrons of lad and lau did not want to subscribe to yet 
another mailing list (as the list subscriber statistics clearly 
indicate), and so voted for announcements to always appear on lad/lau in 
addition to the announce list.

[linux-audio-dev] New Linux Audio Column in Linux Journal

[Joern Nettingsmeier]

hello linux audio enthusiasts!

reading lwn.net this morning i found that the linux journal has a new
linux audio column in their online edition, written by dave phillips.
the current issue is at
http://www.linuxjournal.com//article.php?sid=7283 .
the content of this first issue will not be news to you, since it's
basically a plug for the world's finest linux audio mailing lists, which
you already seem to know about :)
still, it's an interesting read, and it has had an effect already: about
30 new subscriptions (in addition to the usual continous growth) since
wednesday... (see http://www.linuxdj.com/audio/lad/subscribe.php3 .)
to all new readers: welcome aboard!

best,

jörn

Very true, but I dont think I asked to compiler to use strict aliasing,
can you send an example gcc line make spits out? I've checked a fix into
CVS that should stop alising for most people anyway.

Anyone know why some gcc's check for aliasing?
 

however, when i use --enable-sse, gcc falls apart:


Oops. Yes, that a known problem, but I think the README file is a bit
misleading - its supposed to be hinting that you should build FFTW with
--enable-sse, not the plugins. gcc's automatic SSE support is not very
good (which is all it enables IIRC), and used to produce worse code.
so i can safely use --enable-sse with fftw, when it produces an internal 
compiler error with swh-plugins???

If your gcc is new enough it might ne better, i'd be happy to hear if it
is. I'l change the README.

to further boost the uselessness of this wonderful thing, how about

Re: [linux-audio-dev] GMPI - requirements

One of my tasks as part of GMPI is to provide a draft of the requirements

required or desired that will make GMPI be the open music platform we need.
Feel free to email me privately or publicly.  I'll be happy to condense
ideas and to extract requirements from whatever you have for me.
Trying to get the ball rolling again...
not exactly requirements, but thinking about ladspa and jack lead me to 
a couple of important meta-features for every new killer API:

technical:

* it should be elegant, or even beautiful
* it should be fun to program with
* as an extra bonus, it should be easier than programming on a lower 
level (as with jack vs. alsa)
* it *must* be easy to support in host applications
* it *must not* force any particular choice of toolkit or language upon 
the implementer of either the host or the plugin
* it should work ok right now, instead of being perfect never

social:

* it must be free without loopholes (bsd or lgpl)
* specs and sdk must be available free-of-charge
* the surrounding community must be hospitable towards non-professional 
developers
* both the licensing and the community atmosphere should not discourage 
closed-source commercial implementations while still conveying enough 
"free spirit" to make commercial vendors play fair and participate in or 
even donate something back to the community

i have not followed gmpi at all, and some of these points may not be 
applicable. but they are what puts the "yehah!" factor in 
today's linux audio, and have definitely lifted our community to a level 
where almost everything is possible.
