play_sample3alleg
Plays a sample. allegro game programming library.
Usage
#include <allegro.h>
int play_sample(const SAMPLE *spl, int vol, int pan, int freq, int loop);
Overview
Triggers a sample at the specified volume, pan position, and frequency. The parameters `vol' and `pan' range from 0 (min/left) to 255 (max/right). Frequency is relative rather than absolute: 1000 represents the frequency that the sample was recorded at, 2000 is twice this, etc. If `loop' is not zero, the sample will repeat until you call stop_sample(), and can be manipulated while it is playing by calling adjust_sample(). Example:
/* Scream from the left speaker, twice the freq. */ int sound = play_sample(scream, 255, 0, 2000, 0);
Return value
Returns the voice number that was allocated for the sample or negative if no voices were available.
