Does Audacity have an AI vocal remover?

No. Vocal Reduction and Isolation is phase cancellation: it subtracts whatever is identical in the left and right channels. It has no model of what a voice is, which is why it cannot separate a vocal that is not centred, and why it takes the kick and bass with it.

Why does my instrumental sound thin after removing the vocals?

Because the lead vocal is not the only thing panned to the centre. Kick, bass and snare usually sit there too, and bass is often deliberately mono below about 120 Hz. Cancelling the centre removes them along with the voice. Raising Low Cut for Vocals to around 120 Hz spares the bass region, at the cost of leaving some vocal low-mids behind.

Can I remove vocals from a mono file in Audacity?

No. Phase cancellation needs two channels that differ. A mono file has nothing to subtract against, so there is no centre to remove. Audacity shows one waveform lane for a mono track and two for a stereo track, which is the quickest way to check.

What Strength setting should I use?

Start at 1.0 and listen for the trade. Higher values cancel more of the vocal but also more of everything else in the centre, so the instrumental loses punch. Lower values keep the drums intact but leave the vocal audible. There is no setting that removes only the voice, because the effect cannot tell the difference.

Is there a free way to remove vocals that handles reverb?

Yes, but not through cancellation. AI source separation is trained to recognise a voice, so it works on mono files, off-centre vocals and reverb-heavy mixes, and it rebuilds each stem rather than subtracting one from the other. Audiofilter runs a separation model in the browser for tracks up to five minutes with nothing uploaded.

The short answer

Drop a song into the vocal remover and it hands back two files: the isolated vocals and the instrumental with the voice lifted out. Download the instrumental and that is your karaoke track. The whole thing runs in your browser, so the file never leaves your device.

The rest of this page covers the part most guides skip: what “instrumental” actually means after AI separation, and why two songs can come back from the same tool sounding completely different.

What you get back

Two stereo files, one for each side of the split.

The vocals. Lead and backing voices, lifted clear of the band.
The instrumental. The same arrangement with the vocal subtracted.

A separated instrumental is a reconstruction, not the studio master. A song released as an “instrumental version” was mixed that way from the start. A separated instrumental is the original mix with the voice removed from it, and that subtraction leaves marks. The next section is about those marks.

Step by step

Open the vocal remover. It runs in the browser; there is nothing to install.
Drop in a song. MP3, WAV, FLAC, M4A, AAC or OGG, up to five minutes.
Wait for the split. The model runs on your own processor. A two-minute song finishes in well under a minute on a recent laptop.
Preview both stems. The vocals and the instrumental sit on one timeline, so you can compare them before you download.
Download the instrumental. Export it as WAV, MP3 or AAC.

Why some karaoke tracks come back hollow

Separation does not understand “voice” the way you do. It removes whatever sits in the middle of the stereo image, plus whatever its model has learned to treat as voice.

That second part is where the trouble starts. A kick drum, a bass line, a piano mixed up the middle — all of it can get pulled out with the vocal, because to the model those are also centred content in a voice-like frequency range. The result is a backing track with the voice gone and some of the low end and drums gone with it.

That is the difference between a separated instrumental and a real one, and it is why the same tool can return a clean karaoke track for one song and a hollow one for another.

Which songs work, and which do not

Songs separate cleanly when:

The vocal sits clearly in front and the instruments are panned to the sides.
The arrangement is sparse, with room between the elements.
The recording is modern and well produced.

Songs come back hollow when:

The mix is dense and the vocal is buried in reverb or delay.
Kick, bass and voice all sit in the centre and overlap in frequency.
The recording is old, heavily compressed, or close to mono.

A 30-second test before you commit

Run the split and solo the vocal stem. If it contains a lot of low-end thump or rhythm, that is what the instrumental is about to lose. If it sounds like just a voice, the karaoke track will come out clean.

The limits, stated plainly

Five minutes. Processing runs on your device, not a server farm, so trim the section you need and process that.
Bleed. Dense or heavily processed mixes can leave faint traces of the voice in the instrumental, or a ghost of the band in the vocal stem.
Two stems, not a multitrack. You get vocals and instrumental. You do not get separate drums, bass, guitar and keys.

Frequently asked questions

Is the karaoke track legal to use?

That depends on the source material. Separating a song does not change who owns it, so use the result only if you have the rights to the recording. See the Terms for the details.

Can I use the result commercially?

Audiofilter places no restriction on the output, but the underlying song is still covered by its own rights. A karaoke track of a commercial song is a derivative of that recording, so public or commercial use needs the right licence.

Does the file get uploaded?

No. The model downloads into your browser and runs on your own processor. Open the network tab before you process a file and watch that nothing goes out.

Which formats can I download?

WAV, MP3 and AAC, encoded locally in your browser.

What if my song is longer than five minutes?

Trim the section you need in any editor and process that. The limit exists because separation runs on your own CPU, not because of a paywall.
