Suggested Uses and Practical Applications

Andrew Bencina says: “While designed for use with multichannel audio interfaces it's worth noting that these contraptions may also come in handy when working with a much more basic setup. For example, when using the SoundIn contraption to play a sound file from the hard disk, an AuxIn contraption may be used to channel audio into AudioMulch via your audio interface's microphone or line input.”
