We have been using Sox, a Mac, and a Focusrite Scarlett 2i2 (configured to
be the default audio input) to capture samples from an electret microphone.
We often capture data for several hours and will use the command below to
do so. Is it possible to only capture one channel of the device to keep the
file sizes smaller?
Thanks.
$ ./rec test.raw
Input File : 'default' (coreaudio)
Channels : 2
Sample Rate : 96000
Precision : 32-bit
Sample Encoding: 32-bit Signed Integer PCM

Use "remix 1" to discard the second channel. The Focusrite device
probably doesn't support capturing only one channel.
