Tip: noise cleaning works best on speech. For a song with singing, use "Remove music, keep voice".

How to get clean sound

Which option to choose

Remove background noise is for steady sounds behind speech: generator and UPS hum, ceiling fans, AC, traffic and hiss.

Remove music, keep voice separates a voice from a song playing behind it, so a Reel or YouTube video is not muted or blocked for copyrighted music. Then you can add BolCaps' own free music.

Tips

Pick the right hum filter. Mains electricity hums at 50 Hz in Pakistan, India, the UK and most of Europe and Asia, and at 60 Hz in the USA, Canada and Saudi Arabia.

Do not over-clean. If the voice starts to sound watery or robotic, lower the cleaning strength. A little room sound is more natural than a damaged voice.

Listen with headphones and compare Before and After before you download.

Clean first, caption second. Captions are more accurate on clean audio.

Prevent noise next time

The biggest improvements happen before recording: keep the phone 20 to 30 cm from your mouth, record in a room with curtains and soft furniture, and switch off fans for the take. Our guide How to record clean voice on your phone covers it step by step.

Common questions

Is the music BolCaps adds really free to use? Yes. BolCaps makes it itself, so it can be used in any video, including monetized ones, without copyright claims.

Why does the first clean take longer? The voice model (about 170 MB) downloads once and is kept on your device. After that, a one-minute video usually takes one to three minutes on a laptop.

Is my file uploaded? No. All of the cleaning runs inside your browser.
