Re: [ecasound] writing multiple files

Hi Etienne...

Actually, I think there is a remaining error. Chains 2,3,4, and 5 are four
channels each and the -f:16,1,44100 simply says to write the first channel
of the chain to the file. So I think you will get four identical files,
each containing LFront.wav.

The fix is to do some channel copying in the output chains.

...
>> -a:2 -f:16,1,44100 -o LFront.wav \
>> -a:3 -f:16,1,44100 -o RFront.wav -erc:2,1 \
>> -a:4 -f:16,1,44100 -o LBack.wav -erc:3,1 \
>> -a:5 -f:16,1,44100 -o RBack.wav -erc:4,1

-erc:2,1 says replace channel 1 in the chain with channel 2, and so forth.
I think -erc has been superceded by -chcopy in newer versions of ecasound.
I'll warn you that I'm writing this from memory and have not tried it.

Best regards,

Aaron
