Voicesmith

Real-time voice changer
Voicesmith records an audio signal from the built-in microphone, processes it in
some way and plays it back through the earphones in real-time. There are some of
the classical Phase Vocoder effects available. Voicesmith can also be used to
perform the Delayed Auditory Feedback (DAF) and Frequency-Shifted Auditory
Feedback (FAF).
