What VocaSplitter is

VocaSplitter is a free service for separating recorded songs into audio stems such as vocals, drums, bass, piano, and other parts. Choose two-stem, three-stem, or five-stem separation; processing runs on the server using a source separation model from the Spleeter family. You can preview each result in a browser and download stems individually or as a ZIP. The site accepts MP3, WAV, M4A, AAC, OGG, FLAC, and AIFF files, and stems can be exported in WAV format. It works on the web and in Android and iOS mobile browsers, though the maker says downloading multiple stems is generally easier on desktop. The free plan costs nothing, requires no account, has no upload limit, and adds no watermark. There is no enforced file-length cap, but files longer than about fifteen minutes are more likely to time out. The maker says uploads and generated stems are deleted after processing, are not used for model training, and are not shared with third parties. Separation is an estimate; dense, heavily limited productions can leave audible vocal traces in the instrumental. Support is by email.

Who it suits

VocaSplitter may suit musicians, singers, producers, DJs, teachers, and video or podcast editors who want to work with separate song stems. It works in mobile browsers, though downloading multiple stems is generally easier on desktop.

Limits

The free plan has no upload limit or watermark. There is no enforced hard cap on file length, but files longer than about fifteen minutes are more likely to time out.

Verdict
