Audio Enhancer — Improve Audio Quality Free, In Your Browser

It makes a recording sound better, not just quieter. Sound Enhancer does three things in one pass: removes background noise, shapes the result with a content preset so it sounds present and full, and boosts quiet audio to a usable level. The combination is what improves audio quality — a denoised file alone can still sound thin or too soft.

Any audio. Pick Vocal, Podcast or Voiceover for speech and it runs a voice-tuned engine; pick Instrument or Music and it switches to a spectral engine that lowers the noise floor without chewing into the harmonics of a guitar, piano or full mix. Voice-only tools gut music because they're trained to keep only speech — this one routes music to an engine built for it.

You tell it, by preset. The preset is the routing decision — Vocal, Podcast and Voiceover use the speech-tuned engine; Instrument and Music use the spectral engine — so you never configure engines by hand. If a result sounds wrong, switch the preset and re-enhance; your original is always kept.

Right in your browser, via WebAssembly. It's a web app that enhances locally rather than sending your file off to a server. You can enhance confidential interviews, client calls or unreleased tracks, and once the page has loaded it keeps working.

Yes. Sound Enhancer is free to use — no account, no watermark on the file, and no paywall at the download. You download a lossless WAV with no re-compression. It's funded by optional support, never by holding your result hostage.
