Does anyone have a definitive link for a source tarball (or a tarball), for jack.plumbing? (As recent as possible?) It seems to be in distros, but the source link just goes to a page with a list of apps. http://slavepianos.org/rd/f/207983/ Alex. -- www.openoctave.org midi-subscribe(a)openoctave.org development-subscribe(a)openoctave.org

Quick question. Does anyone know of a standalone big clock that responds to jack transport for seconds, frames, etc? Alex. -- www.openoctave.org midi-subscribe(a)openoctave.org development-subscribe(a)openoctave.org

[LAU] Delay problem real time listening to a live input audio

by Ameur Esseket

Hi all, I am using Ardour for my project, and I have a blocking issue which is the latency when playing and getting the sound back from front speakers. It seems that the audio engine is processing the sound I am providing from my guitar and after 1 or 2 seconds (constant rate) and playing it back. Please advise.

[LAU] SSD for audio

by rosea.grammostola

Hi, SSD disks seems to be fast and silent... but are they suitable for audio data, or is it better to just install your basesystem on it? I know the masters of openoctave.org are using SSD for samples, at least. Other sounds on the Internet are that SSD is not perfect for audio (yet). Regards, \r

[LAU] alsa-jack plugin... some patches.

by torbenh

hi... i have looked into the alsa-jack plugin. i think i fixed the main problem which made it cause xruns. git://hochstrom.endofinternet.org/alsa-plugins.git its working quite reliably here now. with the small fix on the xrun front. i looked at the basic usability. i removed the pid and weird stuff from jack client name. and added an option to configure the client name. ------------------------------------------------------------------ pcm.jack { @args [ NAME ] @args.NAME { type string default "alsa-jack" } type plug slave { pcm { type jack client_name $NAME playback_ports { 0 alsa_pcm:playback_1 1 alsa_pcm:playback_2 } capture_ports { 0 alsa_pcm:capture_1 1 alsa_pcm:capture_2 } } } } ----------------------------------------------------------------- this makes jack:client_name devices available. the noauto git branch also contains a more flexible not autoconnecting version. use with your favourite patchbay. ------------------------------------------------------------------ pcm.jacknoauto { @args [ NAME ] @args.NAME { type string default "alsa-jack" } type plug slave { pcm { type jack client_name $NAME } } } ----------------------------------------------------------------- mplayers alsa backend works fine with this. after a bit of mucking around, i built a 32bit version here on my 64bit machine and had 32bit skype connected to my 64bit jackd. would be nice if this could get some testing with jack2 and stuff. -- torben Hohn

[LAU] Switching word clock on M-Audio Delta 1010LT

by Goran Mekić

Hello! I've purchased Line 6 POD X3 Pro, and it works fine with S/PDIF out connected to my sound card if X3 is master clock. When I change master clock on envy24control from internal to S/PDIF everything works fine, but when I need to switch back to internal, it's locked. If I don't switch it to internal, and turn X3 off, every audio app freezes (OK, I can understand why). Current work around is to turn off jack, switch to internal clock, and launch jack again. An audio noob like me doesn't understand why I can switch to S/PDIF clock without problems, but not back from it. Is this a bug? Thanx! -- FreeB(eer)S(ex)D(rugs) are the real daemons

Re: [LAU] Linux/Windows dichotomy

by michael noble

Just out of curiosity, what is it that makes you doubt parallel wine instantiations are usable? I know in the past I've experimented with this technique for running up to 8 parallel instances of audiomulch (each with 8 output channels) with more than enough cpu left over for jackrack(s), 16 channels in sooplooper (actually 2x8) and ardour on the same machine. Using wineasio and jack2, this all ran stable at 256 frames/second. -michael On Oct 21, 2010 11:03 PM, "Mark Knecht" <markknecht(a)gmail.com> wrote: On Wed, Oct 20, 2010 at 6:12 PM, Paul Davis <paul(a)linuxaudiosystems.com> wrote: > On Wed, Oct 20, 20... I run VMWare everyday. Every benchmark I've run runs within 1% of the the same machine running Windows 7 native. For my money Wine, while very well intentioned, isn't worth trying to to shave out .5%. The biggest advantage I get from VMWare and am not sure I'd ever get from Wine is that the main program I have to run in Windows (TradeStation) isn't multi-threaded. Under Windows on my 6 core/12 thread i7-980x I don't use more than 2 threads running TradeStation. (1 for TS, essentially 1 for Win 7 supporting it.) Running VMWare under Gentoo I often run 5 copies of VMWare which equates to 10 threads leaving 2 threads for Gentoo to control all the hardware. I don't think Wine will _ever_ run 5 copies in parallel. Granted, this work is heavily computational and not typical of anything I do in the audio area, but VMWare eliminated my looking Wine for a long, long time. I haven't bothered much with audio on that machine so I cannot say how well apps like Kontakt might work, but audio output does work so watching NetFlix, etc., works perfectly. - Mark _______________________________________________ Linux-audio-user mailing list Linux-audio-user@lists...
