Audio Enhancer AI

You recorded the interview in a café, and it sounded fine at the time. Back home, the espresso machine is louder than your guest. Or it's a lecture captured from the back row, or a voice memo with a fan humming under every word. You can't record it again, and a full audio editor is more than you want to learn tonight.

Audio Enhancer AI is aimed at that moment. Drop in a file, hear the original, enhance it and listen to the difference before you download anything. The about page describes it as "made for people who want clearer speech without learning their way around an audio editor."

It's careful about its limits, which is refreshing. The tool cleans existing audio without generating a new voice. It can reduce fan noise and hiss, but heavy echo, clipping, overlapping voices and speech buried in noise may stay hard to fix.

The free mode needs no account and runs in your browser. It takes MP3, WAV, M4A and AAC files up to 10 minutes each and exports WAV. The free voice model produces mono, 16 kHz audio, which suits speech better than music.

Pro is for the long stuff. It requires sign-in and processes in the cloud, with no duration limit on audio up to 300 MB and on MP4 or MOV video up to 2 GB. Video always uses the paid mode. You buy time in one-time packs: $4.99 for 20 minutes, $14.99 for 120 or $39.99 for 400. There's no subscription, purchased time never expires, and failed jobs give the time back.

According to the privacy policy, dated October 11, 2026, the service is operated by Xiaoming Qian, an individual based in Kunming, China. In Pro, your audio is uploaded to storage and passed to Replicate, the provider that runs the enhancement model.

The policy is unusually frank on two points. Uploaded audio and results use file links that "can be accessed by anyone who obtains the URL, without signing in." And "there is no guaranteed automatic deletion deadline for every uploaded file." It also says your audio isn't sold or used to train general AI models.

So keep anything sensitive in the free browser mode, and save Pro for recordings you'd be comfortable having on someone else's server.

For a noisy voice memo or a rough podcast take, the free mode is a quick fix worth trying before you reach for anything heavier.
