Datapixx(‘EnableAudioLoopback’)

Psychtoolbox>Datapixx.{mex*} subfunction

Enable an internal loopback from the audio outputs to the audio inputs. This
causes sound currently playing on the audio output system to be acquired on the
audio input system. This convenient feature can be useful when developing audio
input software.
Note that when acquiring loopback data, all output volume and input gain
settings are ignored. The acquired data has exactly the same values as the
source output data.
See DatapixxMicrophone*Demo files for examples.
