ALLEGRO_AUDIO_PAN_NONE(3)   Library Functions Manual   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 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)  be-
     cause,  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 orig-
     inal level.

     (Please correct us if this is wrong.)
