adjust_sample - Alters the parameters of a sample while it is playing. Allegro game programming library.
void adjust_sample(const SAMPLE *spl, int vol, int pan, int freq, int loop);
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.

play_sample - Plays a sample. Allegro game programming library.
int play_sample(const SAMPLE *spl, int vol, int pan, int freq, int loop);
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);
Returns the voice number that was allocated for the sample or negative if no voices were available.
