What is Splittr

Product Overview

Splittr is an entertainment extension that uses AI to separate any YouTube video into individual stems, covering vocals, drums, bass, and other instruments, with all processing done locally on the user's device. Separation runs on Meta's HTDemucs neural network accelerated by WebGPU, falling back to WASM on the CPU for older hardware, and no audio is ever uploaded to a server; the only network request is the one-time 172 MB model download from Hugging Face, cached permanently afterward. The extension also detects the musical key of any track with Camelot notation for mixing reference, measures tempo through multi-band spectral flux analysis, and adds real-time pitch transposition in semitones plus BPM adjustment that changes speed while preserving pitch. Each stem can be muted or soloed in any combination during playback.
