[linux-audio-user] Start audio apps in different virtual desktops

by Antonis Galanopoulos

Hi all I m writing a simple script to start a few audio apps and connect them automagically. What I would like is to make certain windows to appear in a different virtual desktop. For example Ardour edit window in 1, ardour mixer in 2, pd in three etc. Is that possible? I use KDE. Is it something KDE specific? I tried to google for it but I dont know what to google for really. Any help appreciated as usual --- regards anton

[linux-audio-user] Announce: Noize Farm Patch Repository

by DevDSP Info

Hi list, Over on http://devdsp.net a new patch repository has just been opened where you can share patches for your favorite music making software with fellow musicians in an open source spirit. The name of the repository is the Noize Farm, which should give you some clue as to its origins: it's a continuation of the Noize Farm mailing list maintained by Dave Griffiths (dave(a)pawfal.org) for users of his Linux modular softsynth SpiralSynthModular. The web version of the Noize Farm isn't limited to SSM patches, however - right now, you can also share PD patches and CSound files. If you have a suggestion for an additional filetype we can support, fire off an email to info(a)devdsp.net and let us know. Bear in mind the Noize Farm will only take text-type patch files, however, and that isn't likely to change :) -- take care, Matthijs de Jonge http://devdsp.net - news and resources for computer musicians

[linux-audio-user] usb audio

by christopher cuse

Hello, I have an up2date red hat 8.0 install with external usb audio device (extigy). I compiled, installed, and loaded alsa modules; the following issues are present: [root@drs0 alsa]# alsactl store alsactl: get_control:194: Cannot read control '2,0,0,Digital In Playback Source,0': Invalid argument [root@drs0 alsa]# play /usr/share/sounds/phone.wav sox: Unable to sync dsp [root@drs0 alsa]# amixer contents <snip> numid=3,iface=MIXER,name='Digital In Playback Source' ; type=ENUMERATED,access=rw---,values=1,items=2 ; Item #0 'PCM' ; Item #1 'Input 1' amixer: Control default element read error: Invalid argument numid=23,iface=MIXER,name='Digital In Playback Source',index=1 ; type=ENUMERATED,access=rw---,values=1,items=2 ; Item #0 'Mixer' ; Item #1 'PCM' amixer: Control default element read error: Invalid argument <snip> This appears to systemic problem May 7 16:00:52 drs0 kernel: ALSA ../alsa-kernel/usb/usbaudio.c:1869: 3:3:1 : format type 2 is not supported yet May 7 16:00:52 drs0 kernel: ALSA ../alsa-kernel/usb/usbaudio.c:2019: 3:3:1 : invalid FORMAT_TYPE desc May 7 16:00:52 drs0 kernel: ALSA ../alsa-kernel/usb/usbaudio.c:1869: 3:3:2 : format type 3 is not supported yet from an unsupported pcm type. has anyone worked around this?

[linux-audio-user] multichannel Audacity testing

by Daniel James

We've done our first night of testing with the Delta 1010, with mixed results. The hardware is: Asus P4PE motherboard (Intel 845 chipset) Pentium IV 2.4B (2.4GHz, 533MHz FSB) Seagate Barracuda IV 80GB M-Audio Delta 1010 (IRQ 9) Matrox G550 Dual DVI (IRQ 10) SB Live (IRQ 11, for soundfonts in hardware with external MIDI keyboard) All other hardware disabled in BIOS (USB, serial ports, parallel port, onboard sound etc) except for Broadcom onboard LAN sharing IRQ 9 - configured, but disabled for recording session with: ifconfig eth0 down cat /proc/interrupts now shows only Delta 1010 on IRQ 9 Software: Linux Mandrake 9.1 upgraded from 9.0 Multimedia patched 2.4.21-pre kernel ReiserFS filesystem on / and /home ALSA upgraded to 0.92 with Cooker RPMs envy24control compiled from alsa-tools 0.93 tarball wxGTK 2.40 compiled from tarball Audacity 1.1.3 compiled from tarball With the Delta 1010 and two input tracks selected in the Preferences, it all works fine. Four input tracks also works. Select eight input tracks and it works fine initially, but after a while something weird happens to the recorded input - I've never seen this behaviour with Audacity in any other context. Suddenly the waveform is drawn as a rapid series of the same shape. Playing the track back, it sounds as it looks: da-da-da-da-da-da-da-da-da-da-da-da-da-da-da-da-da-da-da-da-da-da-da-da-da- Can anyone replicate this bug, if it is a bug? With full duplex enabled, it was even more flaky. I did compile Audacity before the upgrade to Mandrake 9.1, so this may be related. On another computer with just a normal two-channel soundcard, Audacity can dummy 'record' eight channels in full duplex without problems, but then it isn't actually doing much work. Next, we're going to try Thac's RPMs of Audacity 1.1.3 and at least one other multichannel recorder app to see if this is my lack of compilation skills, a system problem or an Audacity problem.

[linux-audio-user] Acid clone for Linux?

by Juhana Sadeharju

Hello. I have read the recent discussion on "one sample per track" arrangers such as Future Beat and Acid Music. I have tested Future Beat which is quite a limited software. Future Beat is an application where each track has one sample looped infinitely and where user may uncover the audio by drawing regions on the tracks. User cannot relocate the starts of the samples as in Acid. Sample starts at 0 and is repeated, as far as I know, at the next beat mark after the sample has ended. That kind of software is good because I don't have to worry about the sync between all samples. But there is a problem: I'm not sure what really is the correct sync between all the samples. I have taken samples from "www.mountedbythegods.com", at download page. Look at the partial file listing below: does jungle_1 go wrong with respect to drum_1? See figure: drum_1 |-------|------- jungle_1 |-----|-----|----- Or would the correct arrangement be following? drum_1 |-------|------- jungle_1 |----- |----- drum_1.wav: 16 bit, stereo 44100 Hz 708652 4.0173 (time in seconds) drum_2.wav: 16 bit, stereo 44100 Hz 352812 2.0000 drum_3.wav: 16 bit, stereo 44100 Hz 707244 4.0093 drum_4.wav: 16 bit, stereo 44100 Hz 351852 1.9946 drum_5.wav: 16 bit, stereo 44100 Hz 706348 4.0042 drum_6.wav: 16 bit, stereo 44100 Hz 325704 1.8463 e_drum.wav: 16 bit, stereo 44100 Hz 325704 1.8463 jungle_1.wav: 16 bit, stereo 44100 Hz 529244 3.0002 jungle_2.wav: 16 bit, stereo 44100 Hz 1411244 8.0002 rattle_1.wav: 16 bit, stereo 44100 Hz 605580 3.4329 rattle_2.wav: 16 bit, stereo 44100 Hz 610348 3.4600 rattle_3.wav: 16 bit, stereo 44100 Hz 303788 1.7221 rattle_4.wav: 16 bit, stereo 44100 Hz 352844 2.0002 The Mounted by the Gods sample set has 55 samples. A few of them are not loops but individual sounds which should be played with a software sampler. So, what Linux arranger I could use for assembling the remixes? It can be a full blown multitrack editor but it has to have some support for handling the beat oriented samples. What software sampler would allow me to synthesize with samples such as "brr_2.wav" and "digeri_2.wav"? I don't have MIDI keyboard but a MIDI sampler is okay as well if there is a way to send MIDI data from a sequencer to the sampler. What sequencer I could use? Please let me know if you try out the Mounted by the Gods samples and loops. I would like to hear if you arrange something which is better than I ever could do. (Check also www.yello.ch for their Soundstation -- another sample set.) Best regards, Juhana

[linux-audio-user] isapnp problem

by Ralf Haller

Hi there, I am having some problems with a ISA plug and play sound card using alsa 0.9.3 with kernel 2.4.20. The card is a snd-opti92x-ad1848. With alsa 0.9.0rc3 and kernel 2.4.29 the card worked fine. Even the isapnp stuff worked without problems. However with alsa 0.9.3 and kernel 2.4.20 it does not work. The card is not found by alsa. I checked /proc/isapnp and found out that the card isn't initialized by isapnp at all. I initialized the card manually with isapnp using the values for IO, IRQ and DMA that worked for alsa 0.9.0.rc3. However with no success. Any ideas what might be the problem? Have there been changes in isapnp support between alsa 0.9.0.rc3 and 0.9.3?

[linux-audio-user] Syncronizing Audio file and sequencer

by linuxmedia4＠netscape.net

Greetings, I'm sure that (one) of the answers to my question is "jack will do the trick" but I would (first) like to know any program that will do it on it's own. I haven't used jack yet because I have my hands full testing all the many apps out there and want to know what they do on their own. When I have the chance to try differnt apps and see what's out there, then I will give jack the time it deserves (I hate "kinda, sorta" knowing a program). Anyways, can I get input from people about which app they find works best with syncronizing (multitrack) audio files (recording and playback) with sequencing. Of course, I will need the flexibility to record a sequence file along with audio files also. So far I've only tried Jazz and it doesn't allow you to playback the audio file from the middle. You are forced to start at the beginning of the file. So obviously, it's important to be able to start in the middle of an audio file. And hey... if it complile with little trouble with SuSE 8.1, it looks like we got a winner. Who knows, it may even come with the distrob. (-: Thanks, and I've gotten a lot out of being on this list.
