NAME
       al_set_mixer_postprocess_callback - Allegro 5 API

SYNOPSIS

              #include <allegro5/allegro_audio.h>

              bool al_set_mixer_postprocess_callback(ALLEGRO_MIXER *mixer,
                 void (*pp_callback)(void *buf, unsigned int samples, void *data),
                 void *pp_callback_userdata)


DESCRIPTION
       Sets a post-processing filter function that's called after the attached
       streams have been mixed.  The buffer's format will be whatever the
       mixer was created with.  The sample count and user-data pointer is also
       passed.

              Note: The callback is called from a dedicated audio thread.
