I was singing along to a song and then I recorded myself.

Now I just want to isolate the sound of my own voice and remove the original sound from the singer.

Is it possible to do it in any way? What if I supply only the original song, is it possible to use that as a template to remove the original singer? Thanks

  • Hmm… the second answer made me think again… do you mean you have a karaoke track with a vocal on, plus the bare karoke? ..or do you mean you have a regular 'record' with original vocal & your own recorded on top of it? From the first you can remove the track, leaving your vocal [see my answer] for the other, there's nothing at all you can do [see Kurt's answer].

  • Maybe, just maybe, you could try to use some kind of a statistical method. I believe that you could give Independent Component Analysis (ICA) a chance. I am not sure you would get any results out of it but it seems like a good candidate when it comes to (Blind) Source Separation.

Short answer: no. You layered your voice on top of an existing vocal, and they occupy the same frequency range, pan (left-right) location, etc. No filtering, phase flipping or incantations I'm aware of could remove the original recorded voice from underneath yours.

Consider this first recording a practice run-through. Buy a karaoke backing track of the tune you want to record and use that. Alternatively, you can remove the vocal from the original recording (mostly) to show the world how it should have been sung.

In theory, if the two audio files are identical other than the added vocal, then you should be able to set them side by side in something like Audacity.

If you can align them to sample-accuracy, then you can Phase invert one of the tracks, which will cancel out all the audio except the vocal.

  • haha i see, but what if one is slightly softer than the other, then its impossible?

  • Volume is irrelevant really. You need to answer the question in my comment above.
