Vocal Separator is a free, AI-powered audio tool that splits a recording into its singing voice and its backing music. Upload an MP3, WAV, FLAC, M4A, or OGG file up to 10 minutes and 100 MB, and the tool returns two downloadable WAV tracks: the isolated vocals and the instrumental. A four-track stem splitter is also available for separating vocals, drums, bass, and other instruments. No account, email address, or payment is required, and the free allowance covers up to two processing jobs per browser per day, with a separate no-upload variant that runs on your own device for shorter files. The results suit karaoke and rehearsal backing tracks, acapella extraction for study or remixing, and practice material for singers and teachers who want to compare the vocal against the instrumental at the same point in a song. The site is upfront about the limits of separation: dense mixes, heavy reverb, and layered voices can leave audible traces, so it encourages listening to both outputs before using them in a finished project. Uploads are stored only temporarily and deleted automatically, and download links expire 55 minutes after processing finishes.
