* and configuration settings. The function new_fluid_audio_driver2() can be
* used if custom audio processing is desired before the audio is sent to the
* audio driver (although it is not as efficient).

/**
* Callback function type used with new_fluid_audio_driver2() to allow for
* custom user audio processing before the audio is sent to the driver. This
* function is responsible for rendering the audio to the buffers.
* @param data The user data parameter as passed to new_fluid_audio_driver2().
* @param len Length of the audio in frames.
* @param nin Count of buffers in 'in'
* @param in Not used currently
* @param nout Count of arrays in 'out' (i.e., channel count)
* @param out Output buffers, one for each channel
* @return Should return 0 on success, non-zero if an error occured.
