Songdonkey

Songdonkey is an audio editing tool. A free browser tool that separates any MP3 or WAV track into 2, 4 or 5 stems using an AI vocal remover. Preview and download every part without an account, with a built in trimmer for long files and processing that typically finishes in about 90 seconds.

SongDonkey is a browser based stem separator that runs an AI vocal remover over a track and hands back individual instrument files. Upload an MP3 or WAV up to 10 minutes in length, choose how granular you want the split to be, and the service returns separated audio you can preview and download at full quality. It sits in the same territory as paid stem splitting tools, but it skips the account creation, the watermarked previews and the credit system. The separation engine is the same across all three modes, so the choice is really about how many parts you need. Two stem mode pulls vocals away from everything else, which is the quickest route to a karaoke backing track or an a cappella. Four stem mode breaks the instrumental side into bass, drums and other instruments, aimed at remixers and mashup builders. Five stem mode adds a dedicated piano part on top of vocals, bass and drums, making it the most surgical option on the menu. There is no parameter tuning to do beyond picking a mode. In practice the workflow is short. Tracks are processed in roughly 90 seconds on average, with the actual time varying by file length and stem count. Every separated part can be auditioned before download, so you can confirm the vocal extraction is clean before committing the result to a project. The site also includes a built in audio cutter and trimmer for files longer than the 10 minute upload ceiling, which means you do not need a separate editor to slice down a long track before splitting. Files over 10 minutes are not accepted directly, so trimming is the expected route for full DJ sets or extended mixes. The audience is broad rather than studio specific. Producers and samplers get isolated parts without re-recording; singers and cover artists get instrumental versions; video and stream creators get clean backing music or isolated vocal clips. Anyone needing finer control over artefacts, batch processing or format conversion will find it thinner than dedicated desktop separation suites, but for a quick free split in the browser it covers the common cases.
