void * dataplus
 Extended user sound data.
 
int baseoffset
 Offset from the beginning of the file (without the header). Used to resume the sound after stand-by.
 
int format
 
int divider
 
int size
 
int mono
 0x10 for Mono, 0 for Stereo output
 
int isStreamed
 Holds whether the sound is streamed or not.
 
u16 volumeLeft
 Volume of the left channel (set volumeLeft == volumeRight for normal operation, another value creates a panning effect)

int(* endCallback )(struct OSL_SOUND *, int)
 Function called when the sound has finished to play.

 Custom function called when the sound must be played.
 
void(* stopSound )(struct OSL_SOUND *)
 Custom function called when the sound must be stopped (not paused, completely stopped)
 
int(* audioCallback )(unsigned int, void *, unsigned int)
 Custom function which must feed a buffer with a certain number of samples.
 
VIRTUAL_FILE *(* standBySound )(struct OSL_SOUND *)
 Function called when the PSP enters in stand by mode.
 
VIRTUAL_FILE **(* reactiveSound )(struct OSL_SOUND *, VIRTUAL_FILE *)

Detailed Description

Structure of a sound in OSLib. You can make your own "drivers" for other sound types but I can't guarantee they will be forward compatible, so please release your source when creating one ;-)
