NAME
al_identify_sample_f - Allegro 5 API
SYNOPSIS
#include <allegro5/allegro_audio.h>
char const *al_identify_sample_f(ALLEGRO_FILE *fp)
DESCRIPTION
Tries to guess the audio file type of the open ALLEGRO_FILE by reading the first few bytes. By default
Allegro cannot recognize any file types, but calling al_init_acodec_addon(3alleg5) will add detection of
the types it can read. You can also use al_register_sample_identifier(3alleg5) to add identification for
custom file types.
Returns a pointer to a static string with a file extension for the type, including the leading dot. For
example “.wav” or “.ogg”. Returns NULL if the audio type cannot be determined.
