NAME

       ALLEGRO_MIXER - Allegro 5 API

SYNOPSIS

              #include <allegro5/allegro_audio.h>

              typedef struct ALLEGRO_MIXER ALLEGRO_MIXER;

DESCRIPTION

       A mixer mixes together attached streams into a single buffer.  In the process, it converts
       channel configurations, sample  frequencies  and  audio  depths  of  the  attached  sample
       instances  and  audio streams accordingly.  You can control the quality of this conversion
       using ALLEGRO_MIXER_QUALITY.

       When going from mono to stereo (and above), the mixer reduces the volume of both  channels
       by  sqrt(2).   When going from stereo (and above) to mono, the mixer reduces the volume of
       the left and right channels by sqrt(2) before  adding  them  to  the  center  channel  (if
       present).
