Frequently asked questions
Will boosting make it distort?
A built-in soft limiter rounds off the loudest peaks, so even high boosts avoid harsh clipping. The tool also shows how far you can go with no change in quality.
Can I boost a lecture or class recording?
Yes. Quiet voice recordings usually sound much clearer at 200–300%.
Does it work on videos?
You can load an MP4 and save its boosted audio as MP3.
Is my file uploaded?
No. Everything runs in your browser.
