Splitter.ai is an AI audio processing service that isolates instruments and vocals from music. Its stem separation is based on Deezer's open source research project Spleeter. A free upload option handles basic separation, while Splitter PRO adds near perfect 2 stem separation, reverb removal and direct YouTube splitting. An API is available for developers who want to build the separation into their own products, and the company says millions of people use it. The service also publishes help pages, a Discord community and a Twitter feed for support and updates.
Musicians who want to practice along with a track, producers hunting for samples, DJs and remixers needing acapellas or instrumentals, and singers building karaoke tracks are the natural audience. Developers can use the API for apps that process audio automatically. Artists can access dedicated services, and people who only need a quick separation can use the free upload without creating a complicated project. The approach suits anyone curious about how modern separation models work in practice.
A producer can pull the vocal from a song to build a remix or mashup, while a guitarist mutes the original instrument to play along. A DJ extracts an instrumental for a set, and a content creator removes background music from a clip. Splitter PRO's reverb removal cleans up isolated vocals, and direct YouTube splitting skips the step of downloading a file. Developers add the API to apps that need automatic stem separation at scale, and researchers can study the technique through the open source foundation. Artists also have a dedicated section with services aimed at their needs, which makes it practical for both hobby and professional audio work.
