Thread: How To Remove Vocals From Music Tracks Using Audacity

Ever get a sudden, inexplicably irresistible desire for karaoke? Maybe you like the music of a song but can’t stand the lead singer? Here’s how to use remove the vocals from most music tracks in a few simple steps.
How It Works

Vocals are normally placed in the “center channel.” Stereo tracks have two channels, but not all of the instruments are balanced evenly. Sometimes the bass is pushed more towards the right channel, rhythm guitar might be found more towards the left, and so on. Usually the vocals are put dead center, so we can split the stereo track and invert one channel. This cancels out the vocals but leaves the rest in tact. Primus often has extremely unbalanced channels. These kinds of tracks usually work well because the vocals are left evenly balanced between the two channels and that makes them easier to remove accurately. Songs with a lot of vocal effects may end up being mangled by the process, and songs with reverb may leave an echo despite vocals being gone.
On the whole, however this process works really well if you start with good quality audio. One of the most well known adages of audio editing is “garbage in equals garbage out.” If you start with CD audio and work from there, the end result will be cleaner and clearer than if you start with a compressed mp3. In HTG Explains: What Are the Differences Between All Those Audio Formats?, we went over different lossless and lossy formats, so make sure you start from a lossless audio file for best results. This isn’t to say that mp3 and the like won’t work, just that lossless audio works much better.

Removing the Center Channel

Fire up Audacity and load your song of choice. I used a very special one for this project, and it’s dedicated to you wonderful readers.

The first thing we need to do is break the song’s two channels into two separate tracks. Click on the little black arrow next to the track title and go down to Split Stereo Track.

Next, pick a channel (it doesn’t matter which) and double click to select the entire track.

Go to Effect > Invert.

If you hit play, you’ll notice the song sounds a little funny. The Inverted channel sounds like it’s coming from around the speaker instead of directly from it. The last thing we need to do to solidify the effect is change each track to “mono.” Click on the title of each track like when you split the tracks and choose “mono” from the menu.

That’s it! You can go to File > Export to save the track so you can use it for your secret karaoke parties.

Cool technique. It all depends on how the song is mixed probably, if the vocals are in the right or left channels there is no way to remove it.

I'm gonna try to make a couple backing tracks for guitar with this method though, thanks.

Wow,wow....cool tip.Someone know's how to extract acappella from a track?

i have researched for this kind a guide long time and finally i can remove the vocals.

Never knew that this was possible, very helpful. Thanks

Great trick, you can use songs in your videos and voice wont interfer with yours.

This is a good tutorial :) not perfect but results are much better than what I've gotten screwing around in audacity before

Sometimes on YouTube or various blogs you can find decent "officialish" or DIY instrumentals but if not then this is great thanks!

Hey man, this is awesome!
I use Audacity to create ringtones for my phone, this will be taking it to the next level!
Muchos Gracias!
