[linux-audio-dev] Writing PCM to left and right channel seperately?

[Ben Loftis]

Tobias,

I wrote a program that does just this some years ago for IED 
(www.iedaudio.com).  What you are doing is not trivial.  When an announcement 
starts on the left channel (for example) you will want to fill the right 
channel with zeroes.  However you must fill the buffers in small blocks so 
that if an announcement starts on the right channel, you can start stuffing 
the right channel without a long delay.  You might want to investigate Paul's 
program JACK for this.  It splits the audio into separate buffers for each 
I/O.

If you really have to have it ASAP, why not just buy an IED system? :)
