Hi everyone
I am using JavaSound on Linux where it as a default uses ALSA. I tried
to figure out how to configure ALSA with respect to JavaSound, but
couldn't find anything. I read that ALSA can, if the sound card hardware
does not support it, do mixing in software. How can I configure ALSA for
For the most compatibility, I would recommend that you tell Java to
use its own software headspace mixer:
Mixer.Info [] mixerInfo = AudioSystem.getMixerInfo();
Mixer.Info useMixer = null;
for (int i=0;imixerInfo.length;++i)
if
Hi Joshua
Thank you for your reply, but I tried Javas software mixer and it gives
me extremely poor performance. I am working on an voice application and
the latency of Javas software mixer is just unbearable. Wouldn't
starting Java with aoss cause it to use OSS instead of ALSA, is that
really
The poor performance is because its a software mixer, not because
it's Java. It totally sucks compared with hardware mixing, but I'd be
very surprised if an ALSA software mixer gave any different performance.
I have to profess ignorance about exactly what AOSS does. All I know
is that
Hi Joshua
When I run my application on Windows it uses DirectSound and DirectSound
does software mixing as well, but is,even with its poor performance,
considerably faster than Java software mixing. So I assumed that ALSA
would perform better than Java software mixing.
I have to admit that I am
First of all bear in mind that by some strange reason, Sun's Java
doesn't use the default card with alsa but hw:0,0, that's why you must
use aoss son java uses oss and interfaces with the alsa card. Os
course, that isn't much of a problem if you use openJDK
Also you should bear in mind that AFAIK
I thought I had read something about hardware mixing for the M-Audio
Delta card. Would you have an example of how to activate mixing with
dmix so that Java Sound accepts it?

Java allows for multiple sound cards to be used. If I install multiple
sound cards I can in Java Sound select which one I want to use for input
and output. Java Sound on Linux does also allow for sound cards with
multiple inputs and outputs. I have a M-Audio Delta 1010LT installed
with 8

Perhaps?
