The WAV Player API provides functions for playing the waveform audio file format(*.wav).

Required Header

#include <wav_player.h>

Overview

The WAV Player API allows you to simply play and stop a wav file. To play a certain wav file, call wav_player_start_new() with a path to the .wav file. When playing a wav file is finished, wav_player_playback_completed_cb() will be invoked.

Functions

int wav_player_start_new (const char *path, sound_stream_info_h stream_info, wav_player_playback_completed_cb callback, void *user_data, int *id)
 Plays a WAV file with stream information of sound-manager.
int wav_player_start_loop (const char *path, sound_stream_info_h stream_info, unsigned int loop_count, wav_player_playback_completed_cb callback, void *user_data, int *id)
 Plays a WAV file multiple times.
int wav_player_stop (int id)
 Stops playing the WAV file.

Typedefs

typedef void(* wav_player_playback_completed_cb )(int id, void *user_data)
 Called when a WAV file has finished playing.
