Short description of Vodi 3.0: 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.
