Audio In CHOP
The Audio In CHOP receives audio from any of the attached audio input devices using DirectSound. It always outputs time sliced audio data. If you want to record the data, use a Record CHOP.
Multiple Audio In CHOPs can simultaneously record from different input devices if the hardware supports it.
