ALLEGRO_AUDIO_PAN_NONE(3)                            ALLEGRO_AUDIO_PAN_NONE(3)

NAME
       ALLEGRO_AUDIO_PAN_NONE - Allegro 5 API

SYNOPSIS

              #include <allegro5/allegro_audio.h>

              #define ALLEGRO_AUDIO_PAN_NONE      (-1000.0f)

DESCRIPTION
       A special value for the pan property of samples and audio streams.  Use
       this value to disable panning on samples and audio streams, and play
       them without attentuation implied by panning support.

       ALLEGRO_AUDIO_PAN_NONE is different from a pan value of 0.0 (centered)
       because, when panning is enabled, we try to maintain a constant sound
       power level as a sample is panned from left to right.  A sound coming
       out of one speaker should sound as loud as it does when split over two
       speakers.  As a consequence, a sample with pan value 0.0 will be 3 dB
       softer than the original level.

       (Please correct us if this is wrong.)
