Greetings.
I would like to construct a dedicated system for recording five
discrete audio feeds (voice-quality) via the line-in jacks each of five
sound cards. Spent the weekend tinkering, but was never able to get
any Linux configuration to work fully with more than one card at a
time, despite each card working independently, and all five working
together under Windows.
Before I tear the remaining hairs out of my head, if anyone has
successfully implemented five (cheap) soundcards with Alsa, for
recording purposes, could you relate your chosen Linux distribution,
choice of card and any caveats?
As long as you don't expect sample sync between the seperate soundcards,
it should be verymuch possible to record from 5 different soundcards at
once, i.e. with 5 arecord processes.
Has anyone ever studied the timing variations between soundcards? Ie, is
it 10^-6 ( which one certainly could get out of a crystal oscillator, but
which would correspond to a one sample shiftin about 20sec, and a 100
sample shift in an hour) or worse? Or better?
