Splitter.ai

Splitter.ai is an AI audio service that separates songs into stems such as vocals, drums, bass and piano, with extra models for reverb and noise removal. It runs in the browser, on desktop and on mobile.

Splitter.ai is an audio processing service from a Swedish research company focused on AI-driven audio technology. Its best-known function is stem separation: upload a song and the system pulls the recording apart into individual parts, so vocals, drums, bass, piano and other instruments can be used on their own. The company says it was founded by an established music producer and audio engineer, and that its tools are used by producers, DJs, artists, audio engineers, karaoke fans, forensic specialists and scientists. In practice the workflow centres on choosing a model and uploading a file. The free 5 Stem model separates vocals, drums, piano, bass and a catch-all "other" track covering guitars and synths. A 2 Stem model splits a track into just the instrumental and the vocals. Higher-quality models carry an HQ label: 2 Stem X, Unverb X (reverb removal) and Antinoise X (noise reduction). The homepage notes these can be tried for free after logging in. Uploads enter a queue that typically finishes in about a minute, and a short cooldown between uploads, which grows or shrinks with demand, protects the servers. An upload history panel keeps track of earlier jobs. The service is offered in several forms: a cloud version in the browser, desktop downloads for Windows and Mac, and mobile apps for iOS and Android. A paid tier called Splitter PRO adds near perfect 2 stem extraction, reverb removal and direct YouTube splitting. The free service has been moved to a Splitter Dashboard, and the site currently runs a donation campaign to keep it operating. Among stem separation alternatives, Splitter.ai stands out for its range of specialised cleanup models rather than a single splitter. Users should note the site's warning about unlicensed music: responsibility for copyright compliance rests with the person uploading, and the team says it will cooperate with rights holders who raise concerns. It suits remixers, karaoke makers and practising musicians who want quick separations.
