32// NullAudioOp.h
33// * PURPOSE
34//   To test the IAudioOp framework, this file includes
35//   an IAudioOpFactory implementation that creates
36//   'do-nothing' operations.  (This operation literally
37//   does nothing -- it doesn't even copy the input buffer
38//   to the output, so beware!)
