Removing a lead vocal from a Stereo Recording
Note: This technique works using the same methods as hardware boxes costing many times the price of this product. However, it has the same limitations as many of these hardware solutions in that the vocals to be removed must have been mixed in the exact center of the stereo field by the recording engineer. Many recordings are made this way, but some are not.
LDB-IF THE VOX AREN'T IN OR EXTREMELY CLOSE TO THE MIDDLE NOTHING WILL WORK!
The following procedure will very often be effective in removing a lead vocalist's performance from a stereophonic recording. This is useful when you desire to over-dub your own rendition of the performance onto the original song. If there is a lot of ambient sound (reverberation) associated with the original artist, it may not be removed along with the vocal itself. This is seldom a problem, since the ambient sound is not very distinct, and will not drastically deter from your own over-dub performance. It is important to note that this technique will not work with a monophonic source. It is also important to note that this technique very much relies on the type of material you are using. It will produce better results on more acoustic type music and sometimes no success on music with heavy walls of instruments.
1. Open your desired stereo file.
2. Open the Channel Blender feature (Effects Menu).
3. Set Left and Right to 100% blend
4. Select Invert Phase on the left channel
5. Select Blend to Mono and choose “Below”.
6. Set the Blend to Mono adjustment to 160 Hz.
7. Click on the Preview button.
8. You should hear the Source .wav file with an attenuated lead vocalist, with perhaps a little bit of reverberation (echo) in the background.
9. Adjust one of the two-slider controls downwards first. Observe if the lead vocalist gets louder or softer. If it gets louder, readjust the control upwards, looking for a point on the slider control wherein the lead vocal is nulled out (minimized).
10. Click on "Run Filter."
