About this tool

Quiet lecture recordings and voice memos are a classic problem. This booster applies real gain through the Web Audio API and tames the peaks with a tanh soft-clipper so the result is louder without painful distortion. Everything happens locally; the original never leaves your device. Your file never leaves this page — everything runs in your browser, there is no upload endpoint on this site, and the file is dropped from memory when you close the tab.

FAQ

Is my audio uploaded?

No — Your file never leaves this page — everything runs in your browser, there is no upload endpoint on this site, and the file is dropped from memory when you close the tab.

Will it distort?

A soft-clipper rounds peaks; 2x is usually the sweet spot for speech.

Output?

WAV; convert afterwards if you need MP3.

Can it also lower volume?

Use 1x original or trim instead — this tool's job is boosting.

Why WAV?

Lossless re-export keeps quality; MP3 would add a second lossy pass.
