PitchBox

PitchBox is just a fun application that transforms audio in real-time using various audio effects.

Select "File", choose an audio file (.mp3, .wav, etc) and select one of the 18 weird audio filters.

Or plug a microphone, select "Line In", and transform your own voice in real-time. You may need to configure the microphone in the Windows control panel or in yourcomputer's sound settings (PitchBox just uses the default audio input and output).

For real-time voice transformation on Windows, an ASIO driver such as asio4all (to download and install separately) can reduce the latency.
