Vodi is a tool for modifying pitch, timbre, duration and adding audio effects. Vodi supports independent pitch and timbre modification in the real sense as opposed to other software tools for voice modification: You can hold the pitch constant and modify the timbre and vice versa, or you can modify them independently in desired amounts. Changing the pitch results in a voice that sounds in a different tone as compared to the original. Duration modification enables varying the rate of the audio signal (speeding up or slowing down) without altering the spectral characteristics (i.e. pitch and timbre).

Modification of the vocal tract length results in the alteration of timbre and by shifting the formants one can transform, for example, a male voice into a female or a children's voice.

Vodi supports simultaneous modification of these three characteristics as well as the addition of audio effects.

Vodi supports low-delay real-time operation (around 200 ms. in full-processing mode). Pre-recorded wav files can be used for off-line processing as well.

Vodi has an easy-to-use interface for recording wav files in the desired format and modifying them.
