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 sample instances and audio streams.  Use this
       value to disable panning on sample instances 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.)
