Frequently asked questions
Everything you need to know about Demix and AI stem extraction.
Demix uses natural language prompts, so you can extract the sound you describe — not just a fixed list of stems like vocals or drums. Traditional stem splitters rely on predefined categories, while Demix adapts to the prompt you type in plain English.
Instead of selecting from a fixed list of instruments, you describe what you want to extract in your own words. For example: "acoustic guitar" or "background synth pad". Demix uses your prompt to isolate that sound from the mix.
Yes. Demix can extract any sound you can describe, including background textures, effects, ambient elements, and non-standard audio like crowd noise, vinyl crackle, or specific synth layers.
Demix supports common audio formats including WAV, MP3, FLAC, OGG, M4A, and AAC. Upload your file and Demix processes it securely on our servers — no software to install.
Most songs process in around 1–3 minutes, depending on file length and server load. Paid plans include priority processing.
