Stem Splitter

Audio stem separation as a service, with two capabilities. "stem-split" returns 4 clean WAV stems - vocals, drums, bass, and other. "vocals-instrumental" returns a two-track split: an isolated vocal plus a full instrumental. Send an audio file, get back separate WAV files. Great for remixes, karaoke, practice tracks, sampling, and transcription. Audio is processed privately, exchanged directly with the provider, never uploaded to a third party. Flat price per track, paid in USDC on Solana.
