Do you have a track that you really would like to remix but can’t find the vocal acapella version of this track? Then this is the perfect guide for you.
I will show you 3 different techniques to filter out the vocals of any track in any genre.
Please note that the results may vary by using these techniques. Sometimes it won’t sound perfect. It really depends on the amount of elements the original track is using.
Flip the phase
This technique requires two things, the original track (of course) and an instrumental version of this track.
Start by dragging both of these audio files into your DAW and make sure to line them up perfectly to one another (milliseconds really matters here, so zoom in as much as possible).
Then invert (or flip) the phase on the instrumental track. This will filter out everything in the original track except for the one thing that the instrumental version doesn’t have; the vocals.
It’s incredibly easy to do in all major DAW’s and the results are always perfect.
iZotope RX 7
iZotope RX 7 is an amazing tool for every kind of audio editing and audio repair. It does have a lot of features that’s usable for anyone working with audio, but when trying to filter out acapellas it has a great tool called “Music rebalance”.
Start by dragging in the original track into the plugin. You will see the waveform and you will be able to listen to the track.
Press the “Music rebalance” tool in the down right menu and a window with a few faders will pop up. These faders are for the different elements in a track such as voice, bass, percussion and other.
Drag down the faders to – infinity for all the faders except voice. This will filter out everything in the track except the vocals, which is what we want to keep.
Press the “preview” button in the down left corner of the music rebalance window and you can test out the results. Does it sound good already? Great.
If it doesn’t sound good however, try to play around with the “Sensitivity” fader. This will change how harsh the filtering is and may give you better results. Somewhere around 7-9 is usually the best range for EDM-tracks.
Audacity vocal isolation
This technique is pretty similar to the one above, but instead of using iZotope RX 7 which is a paid application, we’re gonna use a free one called Audacity.
Audacity is a free audio application that’s been around forever. You can use it for so many things like recording and audio editing, but it also has this pretty unknown feature called “Vocal reduction and isolation”.
Start by dragging in your track into Audacity. Go to “effects” and select “Vocal reduction and isolation”.
This will open up a small window with a few options and faders. Press the “action” option and select “Isolate vocals”.
Just as iZotope RX 7, Audacity lets you preview the selected option with a button called “preview”. Press it and listen to how it sounds with the default settings.
It doesn’t sound too good, huh? By tweaking the “strength” setting you may get way better results. Try setting it at around 3-4 maybe.
If this doesn’t cut it, you can also tweak the low and high cut. Just as an EQ, this setting will cut out everything over and under the selected frequency range.
When you’re done tweaking the settings, simply hit “Ok” and the file will be rendered inside Audacity. Then just export the isolated vocals to a MP3 or WAV by going to “File” and “Export”.
