Your audio files can be grouped together from the IDE - you can create audio groups from the Audio Groups window, which can be opened from the Tools menu at the top of the IDE, and assign your files to a specific group from the Sound Properties Window. These groups can then be loaded or unloaded from memory as well as have certain properties set for them using the following functions:

1. audio_group_load
2. audio_group_unload
3. audio_group_is_loaded
4. audio_group_load_progress
5. audio_group_name
6. audio_group_stop_all
7. audio_group_set_gain
