extracting Vocal

[Zine-Wave]

Hi

i'm having some difficulties with extracting vocals from a track.
I have a pretty decent instrumental, but when i invert it over de original track the whole thing just gets "cloudy" with lots of reeverb.

Also tried to make an "instrumental" of the original track by cutting out the vocals from it, so i could invert this over the original track, but even this leaves me with the same result as above.

I'm pretty much stuck at this point

anyone got some advice?

I'm using Audacity as audio inverter.


this is the track i'm working on.

You need to put it exactly under it, even 1ms is too much, you need to put it exactly under it.

i've tried for like 2 hours, zooming in 100% just to get them alligned, but even then it doesn't work ..

Extracting vocals using audio inversion is possible in theory, but mostly not in practice. There are a couple of reasons why it will most likely not work in practice.

Firstly, perfect instrumentals are extremely hard to find and if an instrumental is not perfect, the audio will not match and therefore it will not work.

Secondly, when looking at songs with live played instruments, it is safe to say that there will always be timing differences between various parts of the recordings. This makes a track sound more alive and will therefore not be corrected during the production process. As Dark Identity said, one millisecond of difference is already disastrous for the results, so you can imagine that these timing differences are of vital importance for what you are trying to reach.

Moreover, say that you have a perfect instrumental and that you are working with a track which does not include recorded instruments, the mastering process will still influence the results. A vocal is mostly a central part in the mix, so it will push other things away when it is processed using a limiter in the mastering process. This means the audio is not 100% the same and therefore results will not be optimal.

Pretty much as said above. You just won't find a 1:1 perfect instrumental that has also been mastered in the EXACT same way

Additionally, some synths use some randomisation in their generation. If the instrumental is rendered separately, the leads will be different enough not to work. Plus, I've noticed sometimes the tracks don't match up absolutely perfectly in speed. You get a flanger effect. I presume the instrumental has been speeded up 0.001bpm or something just to make the vocal extraction impossible.

Vocal extraction works better for just some words or for 1 sentence
