Vox Reducer is an audio processing app that reduces the level of the main vocal in a stereo music track selected from your iTunes library. Using the target frequency, bandwidth, and intensity settings, the user can "dial in" the current vocal frequency and bandwidth, then add the right amount of vocal reduction. VoxReducer allows users to save custom presets for filter settings. VoxReducer will reduce a good amount of the main vocal track, however, due to stereo effects processing during recording, the vocal track cannot be removed completely.

Every song is different, so settings for one song will be different than another. The amount of stereo effects processing such as delay, echo, and reverb in the mix will have an impact on how much of the vocal track can be reduced. Therefore, the amount of processing may be minimal for some songs. Note: Source audio files MUST be MP3 or MP4. Audio files must be stored the on the local device.
