Dear nshmyrev,

if i want to record 2 channel from audio device, do i just only modify at line
199 (rec_win32.c) from
wfmt.nChannels = 1;
to
wfmt.nChannels = 2;

thanks in advance.

Looks so if you only want to record, I do not have Windows.

There will be issues with endpointer in multichannel case I suppose, the audio
needs to be mixed on recorder output anyway.

after modified number of channels i got error:
waveInOpen error 32: The specified format is not supported or cannot be
translated. Use the Capabilities function to determine the supported formats.
FATAL_ERROR: "continuous.c", line 403: Failed top open audio device
