Enhancement: Ability to save audio

[riban-bw]

Having created my masterpiece it may be advantageous to be able to save the recorded audio to file and restore into a new ALO session.

Maybe as an initial (simple) implementation the audio could get saved to files (maybe it already does?) which the user may manually recover. Prehaps when starting up it could look in a location for existing files and use them if they exist. This combination may allow a manual save and restore mechanism.
