adjust_sample(3alleg4)						  Allegro manual					    adjust_sample(3alleg4)

NAME
adjust_sample - Alters the parameters of a sample while it is playing. Allegro game programming library. SYNOPSIS
#include <allegro.h> void adjust_sample(const SAMPLE *spl, int vol, int pan, int freq, int loop); DESCRIPTION
Alters the parameters of a sample while it is playing (useful for manipulating looped sounds). You can alter the volume, pan, and fre- quency, and can also clear the loop flag, which will stop the sample when it next reaches the end of its loop. The values of the parameters are just like those of play_sample(). If there are several copies of the same sample playing, this will adjust the first one it comes across. If the sample is not playing it has no effect. SEE ALSO

NAME
play_sample - Plays a sample. Allegro game programming library. SYNOPSIS
#include <allegro.h> int play_sample(const SAMPLE *spl, int vol, int pan, int freq, int loop); DESCRIPTION
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 call- ing 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. SEE ALSO
