have someone ideas about best algorithm to divide sound among diffusor?
if someone of you is interesting, pls reply me...thanks
I've just been working on something vaguely related to this. I have
a little program "weave" which combines two stereo wave files to
make a 6 channel wave file, with front left/right from one of the
original files and rear left/right from the other. (At present,
center and lfe are faked.) I wrote it because I found some demo
files on the web with 4 channels in pairs of wave files, and I couldn't
play them with Alsa aplay.
The relation to what you ask about is this. You could use sox, say,
to process copies a file to add different reverberations, or whatever,
then weave them together to make a 5.1 file.
The program, and a 6 channel playing utility, are based on example
programs from the libsndfile distribution. They're here:
ftp://ling.lll.hawaii.edu/pub/greg/surround-utils-0.0.1.tar.gz
and I included a README with references to the demo files you
can weave together.
