10.4: Fun with Audio Units
Authored by: kanenas on Dec 21, '08 01:17:40PM

As a semi-practical application of this technique, you can send the filtered audio stream to a VoIP app (such as Skype or iChat) to disguise your voice. In iChat, this goes well with backdrops and video effects. Of course, the person at the other end could use the same technique to undo some of the effects (such as pitch shift). Hypothetically, you could implement an analog audio scrambling system using custom filters and AU Lab on both ends.
