A Pentium-M 1.4GHz with 2 GiB RAM was plenty, too. My current laptop is a Core2Duo (OK, with 8 Gig, but those are not in use for audio production) and can work with a project in Ardour with about 20 tracks plus buses and effects all over the place (EQ, comp, reverb ... sometimes a amp/speaker simulation, too) just fine. You'll find that CPU load is not that high, unless you go for extremely low buffer sizes (below 128 or so). The crucial point is to have the system properly configured and to avoid bad luck with certain hardware that just won't work properly. Even frequency scaling with the 'ondemand' governor is no problem with my Core2Duo (also with the Pentium M back then). It might be a problem for you, though, but I actually doubt it. I suspect some software issue interfering with the operation of your gear. Especially if the xruns are regular. A fresh install of Ubuntu Studio _should_ not feature the usual suspects, though. 5. For the microphone, is it ok get a USB microphone? I heard that it's messy handling multiple sound cards with jack. If yes, then what is the best way to connect a microphone? Multiple sound cards are possible, but it should be avoided for simple setups, especially if the cards are not linked to a common clock (I run two Firewire devices that are in sync via S/PDIF). An USB microphone is a separate sound card. Best aquire a normal analog microphone and plug it into the same sound card that offers the MIDI interface. If your keyboard only has USB, not an actual MIDI port, then you could try a USB mic for cost-effectiveness, but you'd be more happy with an audio interface that handles both the data from the MIDI keyboard and the microphone. On the other hand ... I do wonder if there is a sync problem between a MIDI-only USB device and an audio USB device at all (apart from the jitter that Ralf refers to and which can but doesn't have to be a problem you encounter). When MIDI only does input, then the clock is ... you?! I'm not sure about the timing in the protocol ... but does it actually make a difference to have unsynced devices in this case? A question for the audience;-) In any case: Getting two devices into a JACK setup is more work than getting one device in there. Plus, a separate analog microphone can have other uses (on stage, in a different studio).

Horrific jackd xrun behaviour after upgrade from US 10.04 to 12.04 (Re: R: Audio issues in 10.04)
Am Mon, 17 Sep 2012 15:30:49 +0200 schrieb Thomas Orgis thomas-fo...@orgis.org: Please post the output of $ /etc/init.d/rtirq status Will try to get to that tonight. Well ... this is interesting. I tried AVLinux and this also showed massive xruns, with the added twist of ffado giving up on the device after some time. I then thought that maybe swapping the firewire card to another slot might help. It shared IRQ with some USB ports. I shoved it into the x16 slot (using onboard graphics). Now, would I have been properly awake at that time, I'd have thought that the generally abysmal performance cannot have something to do with the firewire card, as it also shows for internal audio and a USB card. But, perhaps it was a step towards the final goal. Thing is, the machine did not want to start after swapping the firewire card. Pulling the card out, waiting, connecting/disconnecting power ... and the machine boots again. To shorten it a bit: I must have had something funky with the power connection to the card. On the same wire branch s a SATA power adapter for the 3rd hard disk and I suspect it having had some bad insulation, causing flaky current / shorting out. That would explain the box dying on moving said branch about a bit, and some protection circuit preventing powering on again (for some time). I managed to get the thing running again after adding insulation to the supposedly faulty adapter, and what might play a part: The BIOS got reset. I'm with defaults there now. I'm leaving the box running for the day with JACK on firewire under UbuntuStudio (my partial KXStudio). During the first minutes I did not see one underrun and could record a bit with Ardour. II faintly remember that I checked internal audio, too, and it seemed to be fine. So it could be down to flaky power to the firewire card / the system at all (but how could that subtly influence the machine without killing it outright?) or, what I think is more probable, some BIOS setting. I'll check that later, if the test is successful. Anoter remote possibility would be that the machine freaks out generally when the first PCIe slot is occupied --- I'll move the firewire card back to see if that makes a change.

Horrific jackd xrun behaviour after upgrade from US 10.04 to 12.04
Hi, the subject says it all ... I had an install of 10.04 that worked. Only issue seemed to be instability when recording while a USB drive is connected. So, considering that perhaps this is a sign to replace a mainboard with broken onboard USB (used a PCI add-on card, which might have worsened the interrupt situation), I did replace it and the machine worked fine during a session. Now with the fully replaced hardware (Asus AM3 board with 780G chipset, Athlon || X3 460, 8 Gig of Kingston DDR3 ValueRAM, 250 G Seagate SATA boot, 2 WD EADS on mdraid for recordings and not to forget VIA firewire on PCI-E (same card as before)) and the update to ubuntu 12.04 (yes, should have tested the final hardware with 10.04 first, eh?), the performance is hindered by jackd not being able to keep steady without generating xruns at a some rate. Not really constant rate, though, also its behaviour depends on client connections (even when just connecting meterbridge, this seems to help triggering xruns a lot). A very interesting fact is that using 3x512 periods (or bigger) is less stable even than going down to 3x32! With big periods, I get xruns right away, while with the low setting, I was able to get an hour of recording done, but that ended prematurely -- I _guess_ that this was because of some software glitch (like xrun handling) and not due to the bass player nudging the keyboard by chance. But I cannot be sure about that. Now, I do have the lowlatency kernel already installed, also fresh jack/ardour from kxstudio ... have rtirq setup updated by dpkg (firewire in there instead of ohci1394). What are the ubuntu studio folks' thoughts on this? Did you encounter _more_ stable jack with extremely low latencies? But since it is not really stable and glitch-free in any config, this interesting characteristic does not help. Oh, and it happens independent of cpufreq governor. I do use XFCE and the integrated radeon with open source driver. Any help on getting that setup stable again is appreciated ... or should I simply go back to 10.04 (and hand-install current ardour/jack, as I did before)? I figure that I shouldn't even need a lowlat kernel for getting basic 3x512 recording work! Alrighty then, Thomas. PS: Why upgrade at all? Well, I have always a spark of hope that some iteration of the GNU/Linux audio ecosystem will be really stable, without random crashes of Ardour, for example. But I guess one has to live with crashing multimedia apps ... not been that different during my days doing video with Ulead Media Studio on Windows (and the fact that version 5 was less usable than 2.5). signature.asc Description: PGP signature -- Ubuntu-Studio-users mailing list Ubuntu-Studio-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users

Another of course: Of course, I'd like the computed spectral data not only pictures but also as plain (ASCII) data, p.ex. to be able to subtract spectra to determine what a microphone does on its own before entering a specific preamp.

A user I support has a normal laptop with ubuntu (10.10) and a separate machine with Studio. I actually installed from the US medium and thus got the different UI configuration, compared to stock ubuntu: Different optics and different menus (like, the missing Applications and System direct-access menus in the panel). That wouldn't fly at all. So I configured the US install to look just like a default desktop (which took some time since you have to search through forum posts to find anything). The user doesn't want disruption of the known workflow. Not again, after getting accustomed to Linux / ubuntu at all. So, the current / last ubuntu Studio deviations from the normal Gnome 2 install were too much already. I see the question of switching the desktop you get when installing Studio directly as not that relevant to me: I'll install people the vanilla ubuntu and then add Studio packages on top, keeping the known interface. And to be honest, that's the two faces of ubuntu Studio I see: 1. Exactly the same desktop as vanilla, just with added functionality (realtime settings, etc.). 2. Something different. The second category includes the old setup with a changed Gnome 2 configuration, as well as a possible XFCE setup in the future: It's different from vanilla. That's enough for my users not to use it. It doesn't matter for normal users how different it is. Perhaps more different is better to quickly realize that one has to adapt expectations. Pro people who are more dedicated to studio work, who wire up lots of JACK clients and have many desktops filled with those synth / sampler controls, can benefit from a specialized ubuntu Studio desktop. People who just want to record a bit with some provided Ardour templates will use the environment they have on other installs -- otherwise they get confused and annoyed. Just go ahead and change ubuntu Studio desktop to what you think is best -- as long as one can just upgrade a vanilla install with the audio recording packages. Alrighty then, Thomas.

You can get that out of the Alesis io|2, USB 1, duplex, 24 bit stereo, 48 kHz. It uses actual 24 bit sample format ... so that's 3 B * 2 * 2 * 48000 = 563 KiB per second of payload data that fits well into the limit of USB 1.1 (12 MBit/s = 1464 KiB/s), giving space for whatever overhead is present. But yeah, anything more than that gets really tight. You could have a card with 4 recording channels and 2 playback ... that would be 844 KiB/s ... but then, I don't know how much overhead you have with USB audio and also I'd have to review how duplex operation actually affects the available data rate. Also, looking at the devices that are there, USB1 audio for linux goes up to 24 bit stereo, duplex. And yes, USB 2 devices seem to be sparsely supported. For multichannel recording I got a FireWire device... and FireWire audio can be a bitch to get working right (building a good computer setup). Stereo cards work the best. There are a few multichannel cards that work too, but out of those, usually only those will work well that have specific drivers. The one that seems to work nowadays is the Edirol UA-101, the USB2-sister of my FA-101. There is a driver in ALSA, snd-ua101, that reportedly delivers multichannel work. But what's missing is the software control for the direct monitoring mixer. But then, on my FA-101 setup, I don't use direct monitoring from the box ... we have an analog mixer and separate headphone amp for that, the recording interface is just connected via the inserts on the channels (only the send part).

But what I can imagine is that the input gain is set too high -- noise characteristics of amplifiers are not best at full tilt. When JACK settings fix it ... then it's a weird side effect of the driver, certain period setup? Funny. In Ardour the is an option to have Ardour do the monitoring. But I do have to wonder about that - direct, latency-free (virtually) hardware monitoring via the monitor - usb knob is a good thing to have, and use. But well, if you need your guitar distortions applied, I assume you use something like Rakarrack in chain with ardour ... and that can be routed to your monitor output via qjackctl, independently of ardour.

Just try it once; see if your tascam is detected there and then one could also try to identify what's missing in ubuntu. Meanwhile, you indeed can get some work done in AVLinux itself. Though, the current version has funny ardour2 behaviour when you try to disconnect/reconnect to JACK (it crashes with a wine dialog box, I guess the VST support is to blame). As long as you don't do that, you can get recordings done. I did;-) But AVLinux is not that convenient when you want to install it as everyday system, IMHO. It is great when the existing collection of software does the job for you, though. And its rather static nature makes it easy not to bother for updates that just could break your working setup;-) (should have Alsa-firmwareloader on board) and Pure:Dyne. But OpenSuse or Mandriva may do the job as well and they can be tweaked quite easily for realtime-audio. I run Fedora plus CCRMA and OpenSuse 11.2 plus jengelh-Kernel and pack-man packages.

I have to spoil the specific take on USB interfaces: Hey, I hear it when you move the mouse! That's what I got with someone listening with headphones to the main output of my Edirol FA-101. I'm glad that you don't get that on the recordings (I _think_), just superimposed on the analog output portion. But still, I am mightily pi**ed about the lack of protection from such issues (our dear friend Improper Grounding again, I guess) even when shelling out several 100 € for the gear. Be it USB or any other digital interface, I guess you can have luck and the bad sort of which. I do not see a technical argument why a USB-connected device should suffer more than a device connected via FireWire (both being bus-powered, even) ... you can get bitten on both camps. For simple recording tasks, I really like the io|2 -- no comparison in bitchyness to the FireWire setup. I ended up angrily smashing a dual socket mainboard with a hammer because it featured a southbridge bug that just so might be the reason for reliable FireWire audio being impossible -- even using a PCI controller with a good FireWire chip. I strongly suspect that a USB interface would have worked just fine. Perhaps not ultra sharp latency, but without all the fuss. That being said, by current setup with ubuntu studio 10.04 and the FA-101 on a custom PC worked without major hickup the last few weeks ... but I very well remember having to reboot the machine (or at least modprobe-cycle firewire) because the firewire subsystem got stuck because of just another subtle driver issue. The FA-101 is a rather old device, but still tricky. No comparison to just having snd-usb-audio loaded and off we go -- with the added plus that it works without JACK, too. To be fair: USB interfaces may not like being put behind a hub... so they're not _totally_ trivial;-) Alrighty then, Thomas. PS: To be a bit more on topic again; I did not test the MIDI performance of any of my USB or FireWire interfaces (uh, would that work with the FA-101?).

Of course, you can get crap on all sides. I won't argue with your experience, just wanted to add mine for perspective. i dont think the quality of firewire vs USB can be challenged. I do challenge, though;-) The actual sound quality really should not differ if the device is built well (and more and more high-class USB devices are coming to market) -- it's a digital interface, after all. When it is only about recording, with direct monitoring from the device or external mixer, USB should do the job just as well, shoving down the bytes with a certain rate, like millions of thumb drives. MIDI may be another issue... the USB device i use needs the madfuloader OK, that sounds ugly. Of course there are USB devices that are a PITA to use (like that Tascam with the L), but at least there is a category of plug-and-play with the standard USB audio class driver. I don't see how setup should be simpler with a FireWire device where you _have_ to run JACK because nothing else uses ffado. cat /proc/interrupts ... and then that whole business. Yes, I dealt with that. I dealt with a laptop with crappy chipset. I shifted PCI cards around ... this is not funny. Of course, there are ways to get lucky, but I have the feeling that it's the norm to have such troubles when first setting up a FireWire interface, while it is the exception for USB to get a faulty mainboard that for some reason doesn't talk right. The complication with the io|2 was that it refuses to work when you plug it into a hub, needs direct connection. That is a sort of problem that users can be expected to solve: Unplug here, replug there ... aah! With audio tech you do that pluggin' around all the time;-) visit a professional studio, the likely-hood of seeing a USB interface in a rack somewhere, or in the signal path at all would be rather unlikely. Well, before USB 2 devices becoming mainstream, USB was no option for studio work as you only get 2 channels through. FireWire was the only solution to get at least 8 or 16 tracks -- besides PCI cards. I believe one reason to rarely see USB stuff is that simply people don't have reason to ditch working FireWire setups. They bought FireWire gear while digitalizing the studio (or ramping up from internal PC interfaces) and trust that, now. Who knows how it looks in 5 years, or 10? I also have said FA-101 in my rack, but I surely had my trouble getting a reliable FireWire setup (interface chips, interrrupts, mainboards, ...). I have the suspicion that my life would have been easier with some USB gear of _today_. Back then, there was no alternative, really. Of course, you won't see USB gear in my rack until the FA-101 died, or until I decide that I want more than 8 channels, because chaining up another FA-101 won't work right since Edirol managed to break the synchronization in that model... hm, OK: Hooking multiple USB devices up to each other and get them synched is not known practice (to me). Looks like a point for FireWire, still. My point isn't that it's no better than USB, anyway -- it's that it can add complication in situations where you don't need any advantage over USB. Though, I must confess: I do not have experienced a multichannel USB interface in action. All I was talking about was simplicity to get some recording going, where latency can as big as it may be, does not matter, and where 2 channels are enough. I would not dare to get into FireWire for that. Anyhow, this is getting out of hand ... I should stop ranting. Somehow I had to get some frustration off my chest -- combined with the relief of the io|2 just working(tm). Perhaps it is a lucky case ... I just see that people also had their troubles with the Edirol UA-101, mainly because it needs a special driver -- I guess most of the mixers with USB interface are 2-channel after all, so have less issues with just being USB class compliant audio devices.

Someone know this bug with ardour2?
Hi, I reported that one recently, perhaps someone here remembers something like that, too? It would be so nice if recording on Linux would be stable:-/ http://tracker.ardour.org/view.php?id=3213 Quote: I am typing this out of my memory, as the affected box is in the studio, not here. But better a bad bug report than no one:-/ This is an install of ubuntu studio 10.04, with ardour 2.8.6, and jackd 0.118+svn, I presume (I used jack2 before on another install, but I don't remember hacking around in the ubuntu one to get jack2). Ardour quite often is disconnected from jack (for whatever reason, usually _not_ during recording) and the real bummer is that it fails to reconnect the channels/tracks to jack ports. It can connect to jack, but the client name changes from ardour to ardour-01 ... ardour then tries to connect ports for the non-existent client ardour. That doesn't work, of course. I have to exit ardour and start again to get the connections working. This is very reproducable once you got ardour disconnected by some other mischief (I'd need to try if this happens on user requested disconnect/reconnect, but I doubt it). This is is also quite frightening since ardour promises only proper saving of projects when the jack connection is right ... and I had to reconnect things after recovering from the ardour-01 confusion. This gives us (ardour2/Linux and me) really bad press when we (the band) are in a recording session and my band waits where I have to fiddle around with that strange Linux thing:-/ Question is now: Who is to blame for the client name mismatch? Ist it ardour, is it jack? Should ardour verify which name it gets assigned and not try to connect ports for someone else (named ardour where ardour is named ardour-01)?

Am Thu, 8 Apr 2010 10:44:05 +0100 schrieb Ricardo Lameiro ricardolame...@gmail.com: Why Pulseaudio, well Pulse audio is a platform that tries to unite all the old sound architectures and create a easy Desktop audio framework. It is indeed a question why one needs such a sound server on a typical setup. ALSA can do mixing of multiple clients on one device, and it can even route to funky stuff like JACK (or, pulse). I don't day ALSA is perfect (still need to debug ridiculous CPU usage it causes with mpg123 sporadically), but I presume that if it is configured properly and more direct usage of these features irons out bugs, there is no need for pulseaudio. Apps use ALSA plug devices for normal desktop audio work, one app may exclusively use the hw device if it wants, to cut the middlework -- if the hw can do hardware mixing (I had a laptop once that has an internal sound chip that could mix two streams), it could even be several apps. Pulse offers tings like a mixer to control all connected clients (at least I remember something like that... not really using it), but I wonder how people really use that. And: There is also the nagging knowledge that the now-GPL OSS offers such control, too, and works beautifully with low overhead, being compatible to any decades-old Linux audio app. Experience shows that pulseaudio is adding its own problems on top of ALSA problems... I know enough people whose issues with audio were solved by deinstalling pulse. Desktop (laptop) users. I use pulse for my day to day desktop, and jack for pro audio things. when I start jack, pulse just stops, and everything works, if i want to play something through jack, i use a jack-aware app, like vlc. Why would i want to browse around the web, and look at youtube videos, when i am working on pro audio stuff? My setup is a bit different: The studio box is wired up to our monitoring system via a firewire box. Any sound it can produce (apart from fan noise and clattering of the hard disks) has to go through JACK. And yes, in that setup, people want to show each other youtube videos (you know, music videos). I am aiming for a setup that uses the ALSA JACK plugin to make ALSA-apps simply send their sound through JACK. That seems to work, generally. And, one ray of light was that totem on my fresh ubuntu install (hijack attempt: please someone have a look at my posts about the issues I have there...) automagically chose JACK as output option, without any configuration on my side (perhaps coincidence, the JACK plugin being the first tried?). Of course I should deactivate the internal audio to make sure apps rather fail to open any output than the silent one. Another thing to have in mind is that pulse audio is not going away, and it will be used by the other distros also. I am not a pulse defender, in fact i don't like it as much i like alsa and jack, but it is like democracy I have the suspicion that once pulse has settled it's issues and is the dominant and stable audio solution for desktops, something new will come along and again replace the old cruft;-) Alrighty then, Thomas. -- Ubuntu-Studio-users mailing list Ubuntu-Studio-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users

Then, in the booted fresh install, I popped in the ubuntustudio DVD and followed the popup window about accessing that medium as package source with synaptic. Selected the ubuntustudio profile packages... and let it grab a load of stuff from the net, too. This took some time, with the dialup not being that broad banded (about 250 MiB with about 30K/s). 1.1 Known issue: Bad resolution This is fine with plain ubuntu but bad with ubuntu studio: The automatic X11 setup uses a bad resolution. After switching to the ubuntu studio kernel (I assume X11 is not changed), the system wants to run my 15 inch TFT with 1366x768 resolution (I think it was this widescreen res, to big in any case) instead of 1024x768. I knew that from my first install, so I quickly had /etc/X11/xorg.conf created with a fixed set of resolutions. Of course that sucks when we replace the monitor and I have to rember to adapt/delete the xorg.conf ... the default does not work. Bug report needed for this one? Possible that this issue goes away when updating the kernel to 2.6.33-rt10 or so... (I am still wondering if I should install a custom kernel after all ... to include the SCSI driver and hope for reduced rootdelay). 1.2 Big Bad Breakage Now... the crashing plymouth kept nagging me (would a system update really fix this now? -- I need to see if my next visit at the box is long enough for the downloads). It's main function seems to be nagging (and irritate newbies), so I decided to rip plymouth out. Due to a dangerous fling, I clicked on the Software Center menu entry. Searched for plymouth ... removed the daemon... seen that there still is a package for plymouth shared libs... wondered how much stuff might depend on it... figured that one will get warnings about removing dependent stuff (like synaptic does it)... deleted it. B-O-O-M! X11 is killed ... I manage to activate a plain console ... and see that I unwittingly entered a major system fubar. Tried to restart gdm ... there is no gdm ... tried to look after the binary... there is no /bin/ls! Wow. There even is no halt, reboot or shutdown. This system is really ripped apart for good. This is something one really would like to avoid happening to new users, old users ... anyone. This Software Center thingie is supposed to be the bubbly-touchy-feely admin interface for Linux newbies / notcarealots, right? I consider it a serious bug that it hoses the whole install beyond repair for any average ubuntu user (well, except for reinstall). Is this something known? Shall I make a flaming report on launchpad? 2. Second Install Since the system was still pretty vanilla (before the blow-up), I rather decided on starting from scratch, reinstall ubuntu, add ubuntu studio on top again. This time I wanted to avoid waiting hours for downloads, so I saved /var/cache/apt/archives and shoved it back once the basic system was installed. That worked nicely... but what didn't work was the install of archives from the ubuntu studio DVD. 2.1 Aptstinence A first time, the familiar popup about package source CDROM (well, or DVD) being inserted appeared and made me install the first part of ubuntu studio (the desktop stuff, AFAIR). But then, after adjusting the boot config for the rt kernel and restarting... that darned popup did not pop up again. So I tried to manually make synaptic use the DVD. No gain for much pain. When wanting to add a CDROM source, it complains that it cannot mount the cdrom. Also apt-cdrom seems to be confused, too. It might have something to do with the system having too many CD/DVD drives (2 real ones, one virtual from the Huawei E160 modem)... or rather with the automagic mounting system. I have seen that the media was mounted under /media/Ubuntu-bla-bla_, not under /media/Ubuntu-bla-bla ... both directories exist. Maybe synaptic expected the latter mount point while the disc is accessible under the
