Audio Stem Separation API

Split an audio or video file into isolated stems. Two-stem mode returns vocals and no_vocals — the pairing dubbing needs, so replacing speech no longer destroys the music bed. Four-stem mode returns vocals, drums, bass and other for remixing. Pass an audio_url (a video URL is fine; the audio is extracted server-side), poll the request, then download the stems as MP3 or WAV.

You can ask Audio Stem Separation to handle image generation/editing. Powered by Pixazo via the Pixazo API gateway.
