How you can isolate the vocals on a song using the instrumental
In: Other
It depends on how the song is mixed, and it generally works better with tracks that are in mono rather than stereo. It’s to do with a thing called phase cancellation – exactly the same way noise cancelling headphones work. You play a sound, and at the same time you play the same sound but with the waveform flipped upside down. The peaks and troughs in the waveform cancel each other out and you’re left with silence. So – if you use this technique with an identical instrumental track, the sound of the instruments will cancel each other out, and you’ll be left with nothing but the vocals.
Some recording studios use this technique for playback, so a musician or singer can record without requiring headphones and still end up with a clean, isolated track. Here’s an example of guitarist Tommy Emmanuel doing just that: https://youtu.be/69GXkBOPv_U
