inch — Reads from a numbered channel in an external audio signal or stream.
ain - input audio signal
kchan - channel number
inch reads from a numbered channel determined by kchan into ain. If the command-line -i flag is set, sound is read continuously from the audio input stream (e.g. stdin or a soundfile). inch can also be used to receive audio in realtime from the audio interface using -iadc.

The highest number for kchan available for use with inch depends on nchnls. If kchan is greater than nchnls, ain will be silent. Note that inch will give a warning but not an error in this case. |
