SAMPLE(3alleg4) Allegro manual SAMPLE(3alleg4)NAME
SAMPLE - Stores sound data. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
typedef struct SAMPLE
DESCRIPTION
int bits; - 8 or 16
int stereo; - sample type flag
int freq; - sample frequency
int priority; - 0-255
unsigned long len; - length (in samples)
unsigned long loop_start; - loop start position
unsigned long loop_end; - loop finish position
void *data; - raw sample data
A sample structure, which holds sound data, used by the digital sample routines. You can consider all of these fields as read only except
priority, loop_start and loop_end, which you can change them for example after loading a sample from disk.
The priority is a value from 0 to 255 (by default set to 128) and controls how hardware voices on the sound card are allocated if you
attempt to play more than the driver can handle. This may be used to ensure that the less important sounds are cut off while the important
ones are preserved.
The variables loop_start and loop_end specify the loop position in sample units, and are set by default to the start and end of the sample.
If you are creating your own samples on the fly, you might also want to modify the raw data of the sample pointed by the data field. The
sample data are always in unsigned format. This means that if you are loading a PCM encoded sound file with signed 16-bit samples, you
would have to XOR every two bytes (i.e. every sample value) with 0x8000 to change the signedness.

load_sample - Loads a sample from a file. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
SAMPLE *load_sample(const char *filename);
DESCRIPTION
Loads a sample from a file, supporting both mono and stereo WAV and mono VOC files, in 8 or 16-bit formats, as well as formats handled by
functions registered using register_sample_file_type(). Example:
SAMPLE *sample = load_sample(user_input);
if (!sample)
abort_on_error("Couldn't load sample!");
RETURN VALUE
Returns a pointer to the SAMPLE or NULL on error. Remember to free this sample later to avoid memory leaks.

I was wondering how to change the frequency of the beeping sound to a more lower, 'darker' sound. The one I have now just drives me nuts.
