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 con‐
       figurations, sample frequencies and audio depths of the attached sample instances and audio  streams  ac‐
       cordingly.  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).
