Remove background noise with AI voice cleanup
Open Repair & AI tools, choose AI voice cleanup, and upload a recording of up to 5 minutes (25 MB). Approve the price, and the cleaned voice is saved as a new file. Your original is always kept.
It works best for interviews, vlogs, and podcasts recorded in noisy rooms. Clean audio also transcribes more accurately.
Split a song into vocals, drums, bass, and other
Choose Split into stems and upload a track between 10 seconds and 5 minutes. Separation usually takes 1–3 minutes, and you can leave the page while it works. Download each stem as an MP3.
Only separate music you own or are licensed to use. See our Copyright Policy.
Free fixes in your browser
Quick repair trims silence, reduces rumble, and normalizes volume for 16-bit WAV files under 8 MB. Video to audio pulls the soundtrack from MP4, MOV, WebM, or MKV videos up to 10 minutes. Both run on your device, use no credits, and never upload your file.
From Video to audio you can send the result straight to AI voice cleanup or stem separation.
Try it yourself. See the exact price before anything runs, and get credits back automatically if a job fails.
