Stereo Center

Menu Command: Effect | Stereo | Stereo Center

This effect uses a more sophisticated method than the Reduce Vocals effect to separate vocals from music or to separate the stereo center channel from the side channels and allows independent volume control of all channels. A true stereo file is required.

The Center channel area controls the volume and frequency range of the center channel. To keep the center (vocals) and remove the side channels, set this volume to 0.0dB and the side channel volumes to -100dB (off). The result will be mono with both left and right channels containing the center audio. Use From and To to narrow the frequency range to analyze when computing the center channel. To retain bass and treble when adjusting vocals, use a range from about 200Hz to 12500Hz.

The Side channels area controls the volumes of the side channels. To remove the center channel and keep the side channels, set these volumes to 0.0dB and set the center channel volume to -100dB (off). The result will be stereo with the center audio removed from the left and right channels.

FFT settings usually don't need to be changed for this effect.
