Re: Ubuntu Studio Lucid

[laurent.bellegarde]

Hi all,

I'm testing in production condition Ubuntu Studio lucid 10.04 amd64 
under a laptop 64 bits with 4Go ram, ati radeon HD 256Mo.

under classic lucid ubuntu, all the hardware goes fine, especially the 
wifi which was not working under karmic.

I've uploaded all ubuntu studio packages, i've lost the wifi...bad news.

Under RT kernel, the boot is fine, when i arrived to the UBS gdm, the 
connexion to the desktop is not working and i'm going back to GDM...

Under the last generic kernel, connexion to UBS GDM is working.

Kino, kdenlive, cinelerra are working fine, ekd too for video editing, 
openshot, is working too but when you add an video effect to a clip, 
there is a large bug which I declared last week under launchpad.

At this time, i can't say if the RT kernel is working fine, for 
information, the RT kernel has worked on this computer since Hardy's 
release, and was working very well under karmic's release.

Beta 1 is already very stable and works very fast, it'a very fine, and 
it's possible to imagine using it in production.

I must admit, Mac, I find myself confused by your statements.  Why would you
want destructive editing?  We should make sure our definitions are the
same.  By destructive editing, I refer to the act of editing an audio file
in a program, and then those changes are immediately applied to the original
audio file, therefore making the changes permanent (i.e. cannot be undone).
It is common practice to avoid destructive editing like the plague, as you
usually want to retain the integrity the original file just in case you'd
like to go back and do things differently.  If you want a new file that
reflects the changes you have made, then you use the program's 'Export'
feature.

Editing on a per sample basis, as you put it, is not necessarily
destructive, and it is also something that I believe Ardour can do.  I
rarely have need to do such a thing, and as such I cannot be certain if
Ardour does that as well as Audacity.

Hi from the Ardour web page:

Non-destructive, non-linear editing with unlimited undo

What you describe above is indeed modifying the recording, I don't
believe it is considered "destructive" editing.

Audacity will allow the wave form to be edited on a per sample basis,
actually changing the value of the sample at will. I believe this is
considered "destructive" editing.

I would be happy to be wrong, but I don't think Ardour allows such
detailed editing of the raw data.

 De facto you can. Once your edits and effects are to your liking, you
can select a part of your audiotrack with the selection-tool and
rightklick->consolidate with plugins.

I use a german version of Ardour so I do not really know, if the words
are correct but as a matter of fact you can make Ardour write a new file
that holds all your edits and FX and that replaces the former recording
in the track.

This I would consider pretty nearish to reall destructive editig. Still
Ardour lacks some important offline-Tools like note-detection and most
important: noise reduction. For these things I open Sonic Visualizer and
Audacity...

Tom, that is an interesting suggestion, and oddly enough, i have had 
fairly extensive experience with Audacity transferring a portion of my 
extensive vinyl collection to cd.  This is an excellent approach to get 
my computer literacy students to see an additional aspect of computer 
use that they probably have not thought about.
However, the band is quite sophisticated, and I gave the keyboardist a 
quick look at the Ubuntu studio offerings today.  He was quite taken 
aback, and already started plotting implementation.  He knew of the 
potential capabilities looking at the mouseover description of many of 
the devices, but there will be a learning curve.  I hope to both 
collaborate and document the process (life is an art project it seems, 
for me anyway).

Viktor, this is excellent direction, gives quite a bit of fodder to 
start with and maintain...gives me quite a bit of homework, and all 
good.  I will print out your posting and give my cohort Sheldon a copy.

Brian, that certainly reinforces Viktor's posting, and the more links to 
instruction the better.  great stuff, poor Sheldon, it may be more than

And having been both on boards and now volunteering at a non profit, I 
can certainly concur with this.  It is a really hard time for everyone, 
especially the non profit sector

thank you all for the excellent advice, i will look forward to future 
postings and keep you appraised of progress in case you are interested.

Can you actually do destructive editing with Ardour at this point?

That is absolutely correct! Audacity is a nice Editor but not a capable
recorder/arranger. Ardour has all, one needs to work fluently and with
minimum limitations with musicians, that simply want to record and
arrange/mix music. And it can do everything you would do with Audacity
as well. Thanks Jack you can even run Ardour synched to a videoplayer
and thus work on soundtracks as the big boys would do ;-)

Ubuntu Studio, jack and pulseaudio

[Michael Dickson]

Hi, I've been running the Lynx Beta and am really pleased with what I'm
seeing.  In particular the integrated support for jackd w/pulseaudio is
nice.  If jackd is started it handles pulseaudio nicely and my jack
based apps work.  I have one use case however I'm not sure is possible.

I occasionally stream like audio into SecondLife.  The SecondLife client
works nicely with pulseaudio.  To do the streaming I've been using
internet DJ console (built from source, I had some trouble with the one
in the repo).  That requires jack support.  

I start the secondlife client and audio is fine.  Start Qjackctl and as
expected it shutsdown pulseaudio and starts jackd. I can now run my
streaming audio session.  Ideally what I'd like to be able to do is keep
both and be able to monitor the audio from secondlife as well.

I tried configuring a new default.pa in my local .pulse directory and
adding in the jack source and sink module for pulseaudio. If I do that
when I login the gnome gui hangs until I move default.pa out of the way
and kill pulseaudio. I tried ordering things differently in the
default.pa file, load the standard drivers via HAL first and add in the
jack module after. It looks like the jack module is hanging the PA
server because it cant find a running jackd. I was hoping it acted more
like a hotplug setup and made the jackd source and sink available when
they came on line.

Anyway, thats my use case.  I can do without the secondlife audio if
necessary when streaming but if I can get both that'd be ideal.  Any
suggestions are greatly appreciated.  The work that's gone into getting
these two audio systems to behave in 10.04 alone is very nice. Thanks
for that!

Mike

For someone working with audio, you will want to make sure you understand
how to start the JACK audio server.  Oddly enough, for software that is the
heart of professional audio in Linux, there is surprisingly little
documentation on this software.  Here is about as good a guide as there is
on using JACK:

http://en.flossmanuals.net/Ardour/StartJackUbuntu

That is a chapter in a manual on using Ardour, which is the other
application that you WILL want to know if you really want to get the most
out of your Ubuntu Studio install.  The link to the full manual is:

http://en.flossmanuals.net/ardour/

Many people will recommend Audacity, particularly for beginners.  But trust
me, if you plan on getting into Ubuntu Studio and Linux audio for the long
haul,  Ardour is the program you'll want to use.

Speaking of Ardour, I noticed there's a good change they won't reach their
fundraising goals over at Ardour.org this month.  So, as a reminder to all
you audio enthusiasts:  If you're on this list and you use Ardour regularly
and you're not a subscriber, you should seriously consider supporting the
program financially.

Re: not sure where to ask this question, about the audio production possibilities...

[Viktor Mastoridis]

Hi Gabriel,

I am not sure from your email what is the level of your knowledge, so I will
presume you know almost nothing (pardon me if I am wrong)

Here's the way I use UbuntuStudio, and I guess everyone is using it in a
different way

1. Jack (audio server) is at the heart of an audio system - it lets you
route all audio and midi signals:
- hardware audio inputs (guitar, mics) to software (Ardour,)
- software outputs (Ardour, Muse) to hardware outputs (stereo out > amp >
speakers)
- software outputs (Ardour, Muse)  to other software inputs (Effects etc)
- midi inputs (keyboard midi out) to software inputs (Muse)
- other midi signals routing: keyboard (Muse midi out to external synth or
hardware stereo out or Ardour for audio recording of the midi signal)

Please note that some programs let you edit the Jack connections via their
own interface, some even insist on that (Ardour).
-
The second main use of Jack is that it serves as a Master Transport control
- i.e. all 'jack-aware' apps start and stop the playback when one of them is
started/stopped. Of course, you will need to check that jack-transport is
enabled on most of them for this to work.

Audio/Midi recording. There are all kinds of possibilities here. I
personally use

2. Hydrogen - for drums. Comes with a few drums kits, lets you download more
within the program itself. Excellent, intuitive drum-machine

3. Muse - for midi: it has a built-in soft  synth, but I use it mainly for
soundfonts (sf2). Soundfonts (or soundfont banks) are basically good and and
not so good copies/emulations of real instruments (you might want to google
here for MIDI standard, General Midi specifications, sf2 fonts etc)

4. Zynaddsubfx for generated synth sounds; it possesses many banks of ready
sounds, and other users of this list have contributed with patches for its
libraries.

5. Ardour for audio recording (mics, guitars etc), and fx (reverb, chorus
etc)

6. Jamin - once I have all these 4 apps playing parts (drums, midi, audio)
of my music, run them all through Jamin,  trying to create a nice master
track. The jamin output I usually record back in Ardour on a stereo track,
and then right-click > export it on my computer.

here's a good Ubuntu Studio link to get you into the things in a more
technical/detailed way.
https://help.ubuntu.com/community/UbuntuStudio

I hope this helps.
