Gleam Audio cleans up voice recordings and edits audio, all on your own computer. It removes background noise from speech with on-device AI, so podcasts, voiceovers and audiobooks sound studio-clean. Nothing is ever uploaded, and it runs on macOS, Windows and Linux.

Key Features

- Clean a whole podcast season at once: Drop in every episode and remove background noise from all of them in one run.

- Make voiceovers sound studio-clean: Strip room noise from speech and pick how much to remove with one slider.

- Even out audiobook chapters: Match the loudness of every chapter with presets for audiobooks, podcasts, streaming and broadcast.

- Trim the start and end: Cut a recording to the exact moments you pick on a picture of the sound.

- Break up long sessions: Split a long recording into parts at points you mark, or into equal pieces.

- Export for any platform: Convert between mp3, wav, m4a, flac, ogg, opus and more.

Benefits

- Built to make hard things easy: Old-style noise reduction makes you sample the noise and tune settings by ear. Gleam Audio uses an AI model trained on human speech, so it tells voice from noise on its own and cleans it in one pass.

- Studio sound without the studio: Clean recordings used to need a quiet, treated room or pro repair software with dozens of tools to learn. Gleam Audio takes the background noise out of a home recording with one click.

- Your audio stays on your computer: Most AI cleanup tools need you to upload your recordings first. Gleam Audio does all the work on your machine, so unreleased episodes and client work stay private.

- Works with no internet: Cloud tools wait on uploads and stall when the connection drops. Gleam Audio runs fully offline.

- Batch without the upgrade: Many tools clean one file at a time or keep batch jobs for paid plans. Gleam Audio cleans a whole list in one run, even on the free plan.
