StemSplit

StemSplit is an online audio separation service that removes vocals from songs and splits tracks into stems using AI. It addresses the need to isolate vocals, instrumentals, drums, bass, piano, guitar and other elements from audio files or streaming links for uses such as karaoke, remixes, practice tracks and video production.

Users upload audio in formats including mp3, wav, flac, m4a, ogg, webm, aac, opus, aiff, aif and wma, with a maximum size of 500 megabytes. Direct processing from YouTube and SoundCloud URLs is supported without prior download. Output choices include vocals only, instrumental only, both, or full separation in 2-stem, 4-stem or 6-stem modes. Average processing time is 30 to 60 seconds. Additional capabilities comprise 95 percent or higher vocal removal accuracy, beat grid detection, Camelot key notation, one-click Rekordbox XML export, and automatic deletion of files after 48 hours with no use for AI training.

The service targets singers and vocalists who need backing or karaoke tracks, DJs and producers seeking isolated stems for mashups and transitions with DJ workflow tools, and content creators requiring clean instrumentals for videos, podcasts and streams. It operates as a web-based platform with no software installation required. An API with REST endpoints and webhooks is provided for developers, along with integration guides for n8n, Zapier and Make.

Pricing follows a pay-as-you-go model with credits that never expire and no subscriptions. New users receive five free minutes upon signup without a credit card. Paid packages start at 10 minutes for two dollars, with per-minute rates decreasing for larger bundles up to 300 minutes. All plans include high-quality separation, support for listed audio formats, and API access. The same credits apply to both the web interface and API usage.
