hi,
My sound hardware supports only interleaved audio.
I'm writing an alsa application. Which access method will be more
performing : interleaved or non-interleaved? (Or it does not make a
difference?)

With interleaved, samples can be copied from/to your application's
buffer in one big block. With non-interleaved, samples must be
copied individually.

Clemens

@Clemens:
What I wanted to know : right now my application is doing the audio
sample demux/separation (capture) & mux (playback), because I my
access method is interleaved. Will I get any performance benefit if I
access in non-interleaved method ad let alsa do the work?
