Hi


Is there a way to combine multiple mono soundfiles to a single multichannel
soundfile in Csound ?

Suppose I have some short soundfiles:

sf-000.wav, sf-001.wav, sf-002.wav, ......., sf-N.wav, 
where N is a positive integer, say: N = 200

I would like to make a single multichannel soundfile:

soundfile.wav 

And if I play soundfile.wav[123], then I play only channel number 123

I could then play soundfile[a], where a could be a random integer, and loop
it

In this case, not an  option as I still have an upper limit of 16 input 
files to "interlx", as files are simply listed as command line 
arguments. For a huge number of channels I would need to modify it to 
read from a text file. I am not sure how useful that will really be with 
standard WAVE files!

I have made the code below in the SuperCollider programming language, and I
would like to rewrite it in Csound, if I can:



b = SoundFile.collectIntoBuffers("vokalsvaerm/*")*EnvGen.kr(Env.perc, 0.5,
doneAction: 0); 

(
{
var number = b.numChannels, randomNumber, trigger, delayed, panned, sound,
mixedSound, rotatedSound;
trigger = Dust.kr(Array.fill(number,1), 1, -0.5); // Generates random
impulses from -0.5 to 0.5. as a excitation function
randomNumber = TRand.kr(1, number, trigger);
sound = PlayBuf.ar(Array.fill(number,1) ,randomNumber,1,trigger,0,0);
delayed = DelayL.ar(sound, trigger, trigger); // delaying the soundfiles
panned = Pan2.ar(delayed, Array.fill(number,{1.0.rand2})); // pan them out
in stereo field
mixedSound = 0.05*Mix.new(panned);// and mix them to one stereo signal
rotatedSound = Rotate2.ar(mixedSound[0], mixedSound[1], LFSaw.kr(0.1)); //
rotate stereo signal
}.play; // play them
)

yes, you can do similar stuff, just adapt my examples.
