MP3 encoding of one or both versions will create small differences that will make this technique less effective.Īs opposed to the final mono track you get from removing vocals, this method will leave you with a full stereo track. There are places online where you can buy these tracks ( for example and some records even have them on the B side). Many studios release the instrumental tracks (with and without backup vocals) for use with things like karaoke. In order for this to work you will need to have a studio version of the instrumental track in which the instrumental part is identical to the full track. Using an instrumental track to isolate the vocals

Download the Bass to Center Nyquist plugin and install it. Import the original song into Audacity again.Use the steps above to create a track with isolated vocals.The following may let you remove drums which are not centered but keep the vocals: Delete the copied track (click in the at the top left of its Track Control Panel).Now select the original track (click in empty space in its Track Control Panel).and click on the Get Noise Profile button The copied track should remain selected, so use Effect > Noise Reduction.Remove the vocals in the copy by using Effect > Vocal Reduction and Isolation.Select the whole of the copied track (click in empty space in its Track Control Panel).Use Edit > Paste to make a copy of the original track in the new stereo track.Create a new stereo track with Tracks > Add New > Stereo Track.Select the whole track (click in empty space in its Track Control Panel for example where it says "Hz").Make a copy of your original stereo track.It is sometimes possible to isolate vocals by using Audacity's Noise Reduction to capture the noise profile of a song that has had vocals removed, then run Noise Reduction with that profile on the original mix before vocals were removed. It will not work successfully in all cases. But note that the end result may not be total vocal isolation or even satisfactory isolation of the vocals it all depends on how the original recording was engineered.Ī technique using Audacity for vocal isolationĪn Audacity user (Marco Diego) suggested the following technique for using Audacity to attempt to isolate vocals. You can use the Vocal Reduction and Isolation effect to attempt to isolate the vocals by choosing one of the Isolate Vocals in the Action dropdown menu in the dialog. This can help cure the common problem where center-panned bass or Hi-hat is also removed when removing vocals. Vocal Reduction and Isolation also lets you specify frequencies above which or below which audio is not removed or isolated. However the default option for Vocal Reduction and Isolation "Remove Vocals" is to be preferred in most cases because this returns stereo output.
As in Case 1 above, this removes the whole frequency spectrum of center-panned audio and returns a dual mono track. If you only wanted to automate Case 1 in the Vocal Reduction and Isolation effect, you would choose the option "Remove Center Classic (Mono)". Removal of the vocals can often be incomplete leaving artifacts behind this is especially true where there are backing vocals or where reverb (echo) has been applied as this spreads sound sources and makes them very hard to extract from each other.Īudacity includes a Nyquist plugin effect to automate the steps involved in Case 1, at Effect > Vocal Reduction and Isolation. In some music this could mean removing instrumental parts. Note, this removes everything panned in the center, not just vocals, and returns a dual mono result (both channels have the same audio).
The underlying technique in Audacity is to split the stereo track into its left and right channels, make both mono, invert all (or a selected part) of one of them then play back the result. If the vocals are panned in the center of a stereo track the so-called "vocal removal" technique can sometimes be effective by removing what is common to both tracks (that is, the vocals), leaving behind what is different (that is, the instrumentals). Case 1: Vocal Removal with vocals in the middle and instruments spread around them
