5. Sound features
~~~~~~~~~~~~~~~~~
Sound is supported by the ALSA driver: snd_usb_audio
One 16-bit channel with sample and playback rates of 8000 Hz is the practical
limit of the device.
Example - recording test:
arecord -v -d 10 -r 8000 -f S16_LE -t wav foobar.wav
Example - playback test:
aplay foobar.wav

- Olivier Vandorpe, for starting the usbb2k-api project doing much of
the reverse engineering.
