Primo Media has released voxReducer v1.2, a free Audio Unit plug-in for Mac OS X designed to reduce the level of the main vocal track in a stereo music audio file. It will reduce a good amount of the lead vocal track, however, due to stereo effects processing on the vocal track during recording, the vocal track cannot be removed completely.

voxReducer includes four factory presets designed for different musical genres - Jazz, Light Rock, Hard Rock, and Metal.
