Frequently Asked Questions
What is the best prompt to isolate vocals?
Start with 'vocals' or 'lead vocals'. If you want a specific vocal character, try 'lead vocals with reverb' or 'backing vocals'. The more specific your prompt, the better the AI can isolate what you want.
Can I remove vocals to make a karaoke track?
Yes. When you extract vocals, Demix also gives you a 'residual track' that contains everything except the vocals — essentially an instrumental/karaoke version.
What audio formats work for vocal isolation?
Demix supports WAV, MP3, FLAC, OGG, M4A, and AAC. Higher-quality source files (WAV, FLAC) generally produce better results.
How long does vocal extraction take?
Most songs process in 1–3 minutes depending on file length and server load. Paid plans include priority processing for faster results.
Is vocal isolation free?
Yes. You can try Demix free with no account required. Upload audio up to 2 minutes. Paid plans ($9–$49/month) allow longer files and more extractions.
