Is it possible to treat the two (stereo) channels of a Sound Card separately
(I am using them as two completely separate, unrelated, mono outputs), or do
I have to merge the separate data into a 'stereo' buffer and output it that
way (which I can do, but it gets a bit messy) ??

Many thanks,
Denville.

Yes you can treat the input stereo source like two mono channels. When you
open the device with API's functions, you have to open it in stereo mode.
The buffer you have recorded is stereo so you have samples consecutive:
sampl1Left, sample1Right, sample2Left, sample2Right, ..... All you have to
do is to extract the right sequence for the two channels!!!
Bye. Chri.
