#include <allegro5/allegro_audio.h> bool al_save_sample(const char *filename, ALLEGRO_SAMPLE *spl)
Writes a sample into a file. Currently, wav is the only supported format, and the extension must be ".wav".
Returns true on success, false on error.
Note: the allegro_audio library does not support any audio file formats by default. You must use the allegro_acodec addon, or register your own format handler.
