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.
