[linux-audio-dev] alsa, oss , efficiency?

by lemmel

Hi everyone. for a project, we need to be able to play sound (at first look wav file), and we made several tests ; with a created stereo sound, we try to use alsa but the results doesn't fullfill our needs : sound played at the time, T, we want, and finished at the date, D=T+sound duration. (thi is a software with strict time constraints) The sound was always troncated (even with finished software such as xmms, amarok), and even randomly truncated, (sound created with audacity, and exported as WAV 16/32 bit etc). When we use OSS, all seems to be perfect. But, it seems that OSS is nowadays "deprecated", and consequently we shouldn't use OSS. What we can do ? Are our alsa results due to misconfigurations ?

[linux-audio-dev] Alpha release of Aliki

by Fons Adriaensen

For the brave: an alpha release of Aliki (Room Impulse Response Measurement) is now available on: http://users.skynet.be/solaris/linuxaudio along with a manual that should get you started. This is basically the code used at the LAC2006 workshop, cleaned up a but. As said, ALPHA, incomplete, probably lots of bugs. -- FA Lascia la spina, cogli la rosa.

[linux-audio-dev] [ANN] Vmwaredspjack 1.3, Snd-ls 0.9.7.6 and Jack_capture V0.3.8

by Kjetil S. Matheussen

Vmwaredspjack ============= This is the vmwaredsp program, made by Petr Vandrovec, which makes vmware work with esd or arts. This version adds jack support as well. (Unfortunately, jacklaunch (which is a similar program) doesn't work with vmware, but I think Gunter is working on it... :-) .) The program isn't always working that well, but if used with care (don't trust the output too much) and proper tuning, you can use professional windows audio software in vmware using jack for audio communication. Download from http://www.notam02.no/arkiv/src/ Snd-ls v0.9.7.6 =============== Snd-ls is a distribution of Bill Schottstaedt's sound editor SND. Its target is people that don't know scheme very well, and don't want to spend too much time configuring Snd. It can also serve as a quick introduction to Snd and how it can be set up. Changes 0.9.7.1 -> 0.9.7.6: --------------------------- -Proper debug output in case startup fails. -Fixed bug in jack audio. -Temporary remove the fft menu because its not working with the 26.9.2006 version of Snd. Bug found by Dragan Noveski. -Check for the existence of the sndfile.h header file before compiling. If it doesn't exist, snd-ls will refuse to run. Problem reported by Krzusztof Gawlas. -Make sure snd starts up even if no file was loaded during startup. Bug found by Dragan Noveski. -Really apply the workaround for the menu problem. Download from http://www.notam02.no/arkiv/src/snd/ Jack_capture V0.3.8 =================== jack_capture is a small program to capture whatever sound is going out to your speakers into a file. This is the program I always wanted to have for jack, but no one made. So here it is. Changes 0.3.7 -> 0.3.8: ----------------------- *Added the --recording-time option to stop recording after a certain number of seconds. *Quitting with CTRL-C/SIGINT writes remaining buffer to disk before ending program.

[linux-audio-dev] Re: Alpha release of Aliki

by Ben Loftis

Hi Fons. Can you please tell us more about Aliki? I am using Denis Sbragion's DRC program to generate an impulse response file, and his suite of graphing tools to generate various views of the measurement. What is the output of Aliki? Just an impulse response file? In what way is your method different than DRC? Does Aliki use ALSA or JACK for I/O? I'll have a look at the code tonight but I was hoping you could fill me in on the "big picture". Thanks, Ben Loftis

[linux-audio-dev] Clock/Sync tutorials, hints?

by krampenschiesser＠freenet.de

Hi, do you know any good clock/sync tutorials out there? Or do you have any good hints on this? I hope you can help me. Scar -- Finagle's Eighth Law: If an experiment works, something has gone wrong.
