The audio sync group functions let you play multiple sounds that start at exactly the same time and stay in sync (on a per sample level). This enables you to (for example) add various tracks for a single song and then fade in and out sections without having to worry about whether there will be any delay between them. Note that these functions currently only work with compressed audio, ie. *.ogg and *.mp3 format files.

The following functions exist to deal with synchronising audio tracks:

1. audio_create_sync_group
   
2. audio_play_in_sync_group
   
3. audio_start_sync_group
   
4. audio_stop_sync_group
   
5. audio_pause_sync_group
   
6. audio_resume_sync_group
   
7. audio_sync_group_get_track_pos
   
8. audio_destroy_sync_group
   
9. audio_sync_group_debug
   
10. audio_sync_group_is_playing
