| bonjoyee | is ubuntustudio restricted in audio/video formats like ubuntu? | 03:58 |
|---|---|---|
| holstein | ubuntustudio = ubuntu | 03:58 |
| holstein | you can use the same codecs | 03:58 |
| holstein | the same meta-packages are available as well | 03:59 |
| holstein | ubuntu-restricted-extras or whatever | 03:59 |
| holstein | to answer the question, yes | 03:59 |
| holstein | but, ubuntu is not 'restricted' | 03:59 |
| bonjoyee | holstein: i mean, in things like ffmpeg , mencoder...codecs like libfaac are not present ubuntu...same with ubuntu studio? | 04:00 |
| holstein | sudo m@apollo:~$ sudo apt-cache search libfaac | 04:00 |
| holstein | [sudo] password for m: | 04:00 |
| holstein | libfaac-dev - an AAC audio encoder - devel files | 04:00 |
| holstein | libfaac0 - an AAC audio encoder - library files | 04:00 |
| holstein | im running 10.04 | 04:01 |
| holstein | but that would be in 10.04 ubuntu or ubuntustudio | 04:01 |
| holstein | mabye not by default | 04:01 |
| holstein | but in either the main or partner repositories | 04:01 |
| bonjoyee | holstein: no..i know faac, libfaac is available in the repos...but are things like ffmpeg , mencoder compiled with support for it? | 04:02 |
| holstein | bonjoyee: tell me how to confirm that and i will | 04:04 |
| holstein | if you have a file | 04:04 |
| holstein | i'll try it or whatever | 04:04 |
| holstein | ScottL: ping | 04:04 |
| holstein | ^^ | 04:04 |
| bonjoyee | holstein: could you pastebin the output of "ffmpeg -version" | 04:04 |
| holstein | bonjoyee: the packages them selves are the same though | 04:05 |
| holstein | FFmpeg version 0.6-4:0.6-2ubuntu6.2, Copyright (c) 2000-2010 the FFmpeg developers built on Nov 5 2010 10:51:45 with gcc 4.4.3 | 04:05 |
| holstein | bonjoyee: if you know that the packages in ubuntu proper are not compiled with supprot | 04:06 |
| holstein | support* | 04:06 |
| holstein | ubuntustudio doesnt have any different versions availalbe to it | 04:06 |
| holstein | bonjoyee: that -version, is from 10.04 too | 04:07 |
| holstein | bonjoyee: ScottL will know that | 04:07 |
| holstein | but, you can ask over in #opensourcemusicians | 04:07 |
| holstein | if you need an answer right now | 04:07 |
| holstein | falktx would know that to | 04:07 |
| ScottL | hello? | 04:07 |
| bonjoyee | holstein: ok..thank you so much....:) | 04:08 |
| holstein | ScottL: is ffmpeg from the repos built with libfaac support? | 04:09 |
| holstein | mencoder and whatnot... | 04:09 |
| holstein | bonjoyee: http://paste.ubuntu.com/564211/ | 04:12 |
| holstein | i see | 04:13 |
| holstein | --enable-libfaac | 04:13 |
| holstein | thats the good right? | 04:13 |
| ScottL | huh, i don't know holstein, which version of ubuntu are you using | 04:13 |
| holstein | ScottL: im in 10.04 | 04:14 |
| holstein | but i think this is kind of a general question | 04:14 |
| holstein | and i think i know now | 04:14 |
| ScottL | oh yeah, if you ffmpeg -version that should show you it | 04:14 |
| holstein | the output of that is quite a bit of info | 04:15 |
| ScottL | yeah, i wonder if we could grep it | 04:15 |
| holstein | --enable-libfaac is in there | 04:15 |
| bonjoyee | holstein: thank you once again.. | 04:15 |
| holstein | and if libfaac is in the main repos | 04:15 |
| holstein | like when JACK got moved there | 04:15 |
| holstein | and we started getting packages with JACK support built in | 04:16 |
| holstein | and we partied :) | 04:16 |
| bonjoyee | holstein: i got what i was looking for..thanks:) | 04:16 |
| holstein | bonjoyee: cool | 04:16 |
| Monona | sobukus: How exactly did you set your updates to stop while jack is running? I'm having that problem, and could use some pointers. | 05:48 |
| Monona | How do I diagnose the occasional audio dropouts I get while running the 2.6.33-29-realtime kernel and a m-audio fasttrack pro? It happens sporadically in rhythmbox, vlc, and firefox (youtube, soundcloud, flash-based players generally). | 06:52 |
| gordonjcp | Monona: do you get it with the non-realtime kernel? | 07:48 |
| Monona | gordonjcp: Haven't tried yet, actually. | 07:49 |
| gordonjcp | Monona: I've found the realtime patched kernels to be more bother than they're worth | 07:49 |
| gordonjcp | total pain in the backside | 07:49 |
| gordonjcp | sorry, I know that's not massively helpful | 07:50 |
| gordonjcp | Monona: the theory is that a realtime kernel will get you even lower latency, but I find the latency acceptable with just a normal kernel | 07:50 |
| Monona | I've found that I get xruns from normal kernels, even with 50ms+ latency. | 07:51 |
| gordonjcp | hm, you've got something else wrong then | 07:51 |
| gordonjcp | you're not doing something like trying to capture and play back on two different cardS? | 07:51 |
| Monona | It should work, I figure. I just don't know how to troubleshoot in Lucid. Things were working fine in Hardy. | 07:51 |
| gordonjcp | dear knows, I switched to Arch for audio stuff | 07:52 |
| gordonjcp | pulseaudio blew the backside out of it for me | 07:52 |
| Monona | I've heard good things about Arch. | 07:52 |
| gordonjcp | it's good if you like being able to be very very specific about what you want | 07:52 |
| gordonjcp | I spend about 75% of my time in Arch and about 25% in Ubuntu, the latter mostly when I'm testing things or writing docs since the bulk of users of my software are on Ubuntu ;-) | 07:53 |
| gordonjcp | maybe half of them use Ubuntu, and the rest a mixture of other distros including Arch | 07:54 |
| Monona | Now that you mention it, I'm checking my sound settings and my input and input are both set to "Internal Audio Analog Stereo", even though my output is going through the fasttrack. | 07:54 |
| gordonjcp | Monona: in qjackctl? | 07:54 |
| Monona | I had set that before, but seems to have changed itself. | 07:54 |
| gordonjcp | if you lump the Debian users in with the Ubuntu users, maybe as many as nine or ten users on Debianish distros ;-) | 07:54 |
| Monona | Just for regular audio: Rhythmbox, streaming audio through Firefox. | 07:55 |
| gordonjcp | oh, okay | 07:55 |
| gordonjcp | hm | 07:55 |
| gordonjcp | in which case if you're not using jack you may as well not bother with -rt | 07:56 |
| Monona | Things have worked ok in jack. Just when I'm listening to music, it will drop out. Rhythmbox suddenly stops playing the track, Firefox audio will just stop. | 07:56 |
| gordonjcp | weird | 07:56 |
| gordonjcp | right, got to go | 07:56 |
| * gordonjcp -> work | 07:57 | |
| Monona | I use jack for audio production, but I use the same box/login/etc for web surfing, tune listening. | 07:57 |
| Monona | Thanks for the look, though. I'll just keep digging. :) | 07:57 |
| sobukus | Monona: I changed the qjackctl scripts after start / stop of jack to run 'ervice cron stop / start | 09:09 |
| sobukus | service | 09:09 |
| sobukus | and added a sudoers entry to make this passwordless | 09:09 |
| sobukus | as for the system updates ... I disabled the update notifier application in "Startprogramme" ... system menu, programs to run at startup or similar | 09:10 |

| dax2112rush | Does anyone know if E-Mu 0404 usb works on Ubuntu Studio? | 23:07 |
| gordonjcp | dax2112rush: don't see why not | 23:08 |
| dax2112rush | I don't think it's 100% usb audio class-compliant | 23:09 |
| gordonjcp | yeah | 23:09 |
| gordonjcp | you probably find it's okay at 48kHz or something | 23:09 |
| dax2112rush | ok, do you own one? | 23:10 |
| dax2112rush | I just don't want to buy one and find out it's not working as well as I'd want | 23:10 |
| dax2112rush | or do you have any recommendation for a usb audio interface with low latency and good quality? | 23:11 |
| gordonjcp | dax2112rush: I don't, but I have seen people on one of the mailing lists I'm on use them | 23:11 |
| gordonjcp | dax2112rush: I use a Behringer UCA-202 | 23:12 |
| gordonjcp | it's *okay*, not wonderful but not too terrible | 23:12 |
| dax2112rush | gordonjcp: ok, it's not too unsafe then, I guess | 23:12 |
| gordonjcp | the annoying thing about the UCA-202 - and it shares this with a lot of other USB cards using similar chipsets - it's not phase-correct across channels | 23:12 |
| dax2112rush | yeah, I use mine to play guitar through FX, I'd need a preamp with the UCA-202 | 23:12 |
| gordonjcp | one channel is delayed by a single sample | 23:13 |
| gordonjcp | dax2112rush: fuzzbox | 23:13 |
| gordonjcp | that should have plenty of level to drive the line in | 23:13 |
| dax2112rush | gordonjcp: that wouldn't bother me | 23:13 |
| gordonjcp | dax2112rush: tell you what I'm very keen on is my Novation Xiosynth 25 | 23:13 |
| dax2112rush | gordonjcp: yes, I guess. I could try it | 23:13 |
| gordonjcp | USB audio in and out, and a nice wee synthesizer too | 23:14 |
| dax2112rush | gordonjcp: is it 24 bits? | 23:14 |
| dax2112rush | the UCA-202 | 23:14 |
| gordonjcp | no, again, it's class-compliant so it's 48kHz/16 | 23:14 |
| gordonjcp | so is the Xiosynth | 23:14 |
| dax2112rush | oh every class-compliant dev is 16 bits? | 23:14 |
| gordonjcp | http://www.spinics.net/lists/linux-usb/msg33010.html | 23:15 |
| gordonjcp | as far as I can tell | 23:15 |
| gordonjcp | 16 bits ought to be enough for anybody | 23:15 |
| dax2112rush | not too sure, I'm running guitar amp sim and I get lots of noise on high gain settings, I always thought this was probably due to quantization noise | 23:16 |
| dax2112rush | but I'm not sure | 23:16 |
| gordonjcp | for full-scale line voltage the LSB is around -100dBV | 23:17 |
| gordonjcp | -96dBV actually, now I work it out | 23:17 |
| gordonjcp | no, quantisation noise isn't really significant unless you're using unholy amounts of gain to compensate for poor gain structure | 23:17 |
| gordonjcp | dax2112rush: I can't even hear quantise noise at 12 bits, unless I listen really hard | 23:18 |
| dax2112rush | yeah, but I feed that sound through high gain amp sim | 23:18 |
| dax2112rush | so the noise floor must raise quite a bit after the sim | 23:18 |
| gordonjcp | dax2112rush: then structure your gain properly | 23:18 |
| gordonjcp | think about it; if you amplify the signal so much that the LSB is making a noticeable contribution to the noise level, where are the peaks going? | 23:19 |
| dax2112rush | there might be something to do, but It's actually commercial software, I don't have full flexibility | 23:19 |
| dax2112rush | higher, but there's indeed lots of compression | 23:20 |
| dax2112rush | due to the amp sim | 23:20 |
| dax2112rush | how's the latency on your UCA-202? | 23:22 |
| gordonjcp | dax2112rush: I've currently got it set at about 40ms | 23:23 |
| gordonjcp | could probably get it lower, but only by making the periodsize smaller | 23:24 |
| dax2112rush | is that measured or reported by jack? | 23:25 |
| gordonjcp | reported by jack | 23:25 |
| gordonjcp | I've got no real way of measuring it | 23:25 |
| gordonjcp | I guess I could fire a pulse in and time how long it takes to come back out | 23:25 |
| dax2112rush | that's a bit high for me | 23:25 |
| gordonjcp | cbf though, it works, that's all I care about | 23:25 |
| dax2112rush | yeah something like that | 23:25 |
| gordonjcp | I could knock a whole 3ms off the latency by sitting three feet closer to the speakers | 23:26 |
| gordonjcp | as far as I can tell the largest periodsize is only 1024 frames, which isn't really enough | 23:26 |
| gordonjcp | well, depends what you're doing; for recording audio it's fine | 23:26 |
| dax2112rush | I'm running a Fast Track Pro at 256 | 23:27 |
| dax2112rush | yeah, but I use it to play live | 23:27 |
| dax2112rush | it's my replacement for a real guitar amp | 23:27 |
| gordonjcp | as an effects processor? | 23:27 |
| gordonjcp | brave... | 23:27 |
| dax2112rush | yes | 23:28 |
| dax2112rush | I'm not like touring or anything just playing with friends and once in a while a small show | 23:28 |
| gordonjcp | I used to use softsynths and DAWs but I've pretty much done away with all that | 23:28 |
