Yep, 12 is the magic number. Recording works fine. Now, my last question for today
is can I write out a four channel wav instead of a 12 channel wav? I could separate
the file after I record it but it seems silly to be writing all those zeros to disk
since my card only supports 4 channels.
The -erc stuff only seems useful for post-processing... or can it be used real-time
as well?
Thanks,
