How to Extract Vocals from a Song Online

Updated

You can extract vocals from a song online with Vocali.se by uploading an audio file, clicking the separation button, and waiting for the processed vocal and music tracks to download automatically. This works for making karaoke tracks or isolating vocals, requires no software installation or account registration, and typically finishes in under three minutes. The main conditions: your file must be in a supported format, and you need a stable connection for the upload and download.

What Vocali.se Does

Vocali.se is a free one-step service that separates vocals and music from any song or audio file. It runs a machine-learning engine using pre-trained AI models called Demucs to split the audio into two outputs: the isolated vocals and the instrumental (music) track.

According to the site, the service is truly free, needs no software installation on desktop, tablet, or mobile, and does not require account registration. Donations are accepted via PayPal to keep the service online.

Step-by-Step: Extract Vocals from a Song

  1. Select a supported file from your device. Choose the song or audio file you want to process.
  2. Click the "Separate Music and Vocals" button. This uploads your file and starts processing.
  3. Wait for processing. The site states this takes less than three minutes, though it is continuously being improved.
  4. Download the separated files. After a short waiting time, a download starts automatically for the separated outputs.

The expected result is two files: one containing the vocals and one containing the music. You can use the vocal track for remixing or the music track as a karaoke backing.

Supported Formats and Output

The site's FAQ lists "What formats of audio files can I upload?" and "What is the output format?" as common questions, but the provided page evidence does not specify the exact input or output formats. Before uploading, check the FAQ section on Vocali.se for the current format list to avoid an upload error.

Common Issues and Fixes

Problem What to do
File fits the requirement but you still get an error The site addresses this in its FAQ ("My file fits the requirement, but I still get an error, what should I do?"). Check that section for the current guidance.
You want to re-download a previously separated song The FAQ covers "I want to re-download a song I have separated before, where can I find it?" — see the site for where processed files are stored.
You can't find or download a certain song The FAQ asks "Can you help me to find or download a certain song?" — the service separates files you provide, not a searchable song library.
Sound quality is degraded after separation The FAQ lists "Sound quality is degraded after the separation, what can I do?" Source separation can introduce artifacts; check the FAQ for the recommended handling.

When to Use This Approach

Use Vocali.se when you want a quick, browser-based way to extract vocals or make a karaoke track without installing software or creating an account. It suits one-off separations where a few minutes of processing is acceptable.

If you need batch processing, precise format control, or higher-fidelity stems, a dedicated desktop separation tool may fit better — but that requires installation and setup, which this service avoids.
