How to Remove Music from a Song Online and Keep Only the Vocals

To remove music and keep only the vocals, use an online music source separation tool: upload your song, run the separation, and download the vocal track it produces. On Vocali.se this is a free, browser-based process that requires no software installation and no account registration, and processing typically takes under 3 minutes. The main condition to check first is your goal: "remove music" means isolating the vocals, while "remove vocals" means isolating the instrumental for karaoke. This guide covers the vocal-isolation path.

Remove Music vs. Remove Vocals: Pick the Right Output

Both tasks use the same kind of AI separation engine, but you download a different file:

If you actually want a karaoke version, you want the second row — see the related guide on making a karaoke track by removing vocals. The steps below are for keeping the vocals.

Step-by-Step: Separate the Vocals Online

1. Open the tool in your browser. Vocali.se runs in the browser on a computer, tablet, or mobile device — no install and no sign-up.
2. Select a supported audio file from your device. Choose the song or audio file you want to process. Check the format requirements before uploading (see the FAQ section below).
3. Click the "Separate Music and Vocals" button. This submits the file to the separation engine.
4. Wait for processing. The service states it takes less than 3 minutes to process and separate vocals from music, and notes it is continuously improving speed.
5. Download the separated files. After the short wait, a download starts automatically for the separated files. Keep the vocal file and discard or archive the music file depending on your goal.

The engine behind this is Demucs, a music source separation tool with pre-trained AI models, described as machine-learning and AI powered.

What You Need Before You Start

• No software and no account. Vocali.se states the service is free, requires no software installation on computer, tablet, or mobile, and needs no account registration.
• A supported file format. The site lists an FAQ entry for "What formats of audio files can I upload?" — check that entry against your file before uploading, since an unsupported format is a common cause of upload errors.
• A file that fits the stated requirements. If your file meets the requirements but you still get an error, the site provides a dedicated FAQ entry for that case.

Common Problems and What to Do

Upload error even though the file seems fine. The site has a specific FAQ entry: "My file fits the requirement, but I still get an error, what should I do?" — follow that guidance rather than re-uploading repeatedly.

You want a file you separated earlier. The site addresses this directly: "I want to re-download a song I have separated before, where can I find it?" Check that FAQ entry for where previous results are kept.

The vocals sound degraded after separation. This is a known limitation, and the site has an FAQ entry: "Sound quality is degraded after the separation, what can I do?" Separation is a best-effort extraction, so some loss in the isolated vocal is expected; that entry covers the available options.

You can't find or download a particular song. The site notes it does not help find or download specific songs — you supply the audio file yourself.
