Stem Studio
Upload a song AI splits it into vocals and instrumental as soon as you pick it. WAV, FLAC, MP3 or M4A, up to 15 minutes.

Your song never leaves this device: it is split, edited and exported right here in the browser.

The AI split runs on this device, so your music is never uploaded anywhere. Vocals and instrumental always sum back to your original at its own sample rate. The first split downloads the AI model once (64 MB); after that it starts straight away.
