" You can't un-bake a cake or un-fry and egg, and you can't un-mix a song." If you could un-mix, we could record everything at once in mono and we wouldn't need multitrack recording. Usually, it's just something fun to "play around with." None of these effects/methods are perfect. However, there are more sophisticated DSP algorithms that can do it (to some extent). There is no way with simple math to keep only the "center channel vocals" and throw-away the sides. Note that with 2-channels and simple math there are 4 possibilities: Of course, you can also remove the left or right channel and make a mono file containing either left or right (plus the center which is in both channels, of course.) Most Vocal Remover effects have this bass-saving feature built-in. If you don't want to kill all of the bass (usually centered) you have to high-pass one channel to remove the bass before subtracting. Mixing is done by summation, so you are subtracting by "adding a negative". You can do it manually be inverting one channel and mixing.

It's an "old trick" and back in the analog days I built a subtraction amplifier (differential amplifier) to do it. It's done by simply subtracting left from right which cancels everything that's identical and in-phase in both channels. Audacity (free) comes with a Vocal Remover effect (or maybe it's one of the optional downloads).

I don't know what's easily available for REAPER.Īlmost every audio editor has this effect.

Choose the Export Format from the pop-up menu:.Click on File > Export > Export Multiple.In that case you should consider removing the click before the Normalize step, using Click Removal.Ĭongratulations, you are now ready to export the tracks. One problem when copying records is that a loud click in one channel can cause Normalize to create an unwanted change in the stereo balance. In that case, check the box that says "Normalize stereo channels independently". Some consumer-level turntables, tape decks and/or amplifiers may well record stereo channels with a stronger signal in one channel than the other, which you will probably want to correct. The maximum setting is 0 dB, but the default setting of -1.0 dB provides a little headroom as some players can have playback problems with audio at 0 dB. The default choice in this dialog is to amplify to a maximum of -1.0 dB. Click on Select > All, or use shortcut Ctrl + A.In order for the CD to be burned at maximum volume and thus match other CDs in your collection we need to fix this. If you did the original recording properly and avoided clipping, the recording is probably not at the maximum possible volume. Step 3 - Maximize the volume of the recording
