# Audio Files

The Audio Files section in Cloud PBX phone.systems(TM) lets you manage all sound recordings and announcements used
throughout your system.
You can upload, record, edit, and delete audio files in supported formats (.mp3, .m4a, .wav, .flac, .ogg), up to 14 MB
each.

These audio files are used by objects such as Voice Menu, Audio Playback, and Ring Group to play messages or music to
callers.
You can also organize recordings into playlists for purposes such as music on hold, rotating announcements, or queue
messages, enhancing the overall caller experience.
