I love this idea! I was thinking while working on sunau/aifc/wave patches that we can do more than this, unify the entire audio modules,
getting rid of Aifc_write/read and Wave_write/read was in fact my first desire.
 One way that I thought about was to provide an abc and each module would implement that interface.
That way we could create new modules for audio operations for other formats as well. If this sounds like a good idea, I could try to provide a patch for this.
