Vocali.se

Vocali.se is an audio editing tool. A free, no-signup web tool that splits a song into a vocal track and a music track using the Demucs model, with a one-click flow and automatic downloads. Uploads are limited to 20MB or 10 minutes.

Vocali.se is a browser based stem separation tool built around a single job: pulling the vocal track away from the instrumental in a song. The service runs entirely in the browser, so nothing has to be installed on a laptop, tablet or phone, and no account registration is asked for before use. Upload a track, press one button, and the tool returns two files: one with the vocals and one with the music. That makes it a practical route to karaoke backing tracks, acapella samples or study material for anyone learning a part by ear. The engine behind the separation is Demucs, a pre-trained machine learning model for music source separation. Files are processed on the provider's side, with the processing time quoted at under three minutes per song. The upload stage uses FilePond and accepts audio files only, capped at 20MB in size or 10 minutes in length, whichever limit is hit first. Once processing finishes, the separated files download automatically, so there is no library screen to manage and no queue to sit in. The audience is broad rather than professional. Casual users making a karaoke version of a favourite track, singers and cover bands isolating a part, video editors looking for a clean backing bed, and teachers demonstrating arrangement all fit the profile. Because the whole interaction is drag, click and wait, a first-time visitor can complete a separation without reading any documentation. The deliberately small scope is the point: there are no mixing controls, no stem count options and no project workspace. Against fuller stem separation suites, Vocali.se trades flexibility for simplicity and cost. Tools in that space typically split a track into drums, bass and other parts in addition to vocals, and often keep a history of past jobs and offer higher upload ceilings. Vocali.se does two stems, one file at a time, with a hard size limit and a donation request rather than a paid tier. For quick two-way splits of ordinary song files it is hard to beat on friction, but anyone needing multi-stem output or long-form audio should look elsewhere.
