Audio Enhancer is a free online AI audio enhancement tool designed to make recorded speech easier to hear. It helps improve voice notes, interviews, podcasts, meeting recordings, lessons, and videos by reducing distracting background sound, balancing uneven speech levels, and refining tone.

Users can add common audio and video files, choose the main audio issue, preview the result, compare it with the original, and export the cleaner version. Supported formats listed on the website include MP3, WAV, M4A, AAC, FLAC, MP4, and MOV. The website also presents dedicated cleanup options for wind, mouth sounds, breaths, echo, reverb, static, long silences, and more. The service is described as free and usable without signing in, including workflows for longer spoken recordings.

Enhance speech clarity, reduce background noise, balance voice levels, refine audio tone, and remove unwanted sounds such as breaths, mouth noises, long silences, echo, reverb, static, filler words, hesitations, and stuttering.

Support common audio and video formats, offer two AI processing models (AudioCleaner Model V1 and Alpha V2), and provide before-and-after previews. Users can start processing directly in the browser without creating an account, with no duration limit for spoken files.

Improve spoken audio in podcasts, interviews, voice notes, online meetings, webinars, lessons, training materials, social videos, tutorials, and client presentations, making conversations and spoken content clearer and easier to follow.

Reduce background distractions such as fan noise, hum, room tone, and static in indoor recordings. Handle long-form audio, including lectures, interviews, and podcasts, as well as mobile video recordings without requiring audio extraction.
