Note:
- Extreme pitch and tempo changes (for instance 24 semi-tones, which is quite a lot!) can lead to noise.
- Voice reduction quality depends on the input. It works best with little compressed music and assumes that voice was recorded in mono and later mixed into the stereo channels (which is the case for a lot of music recordings)
