TrackGleam

TrackGleam is a browser-based audio mastering application for musicians, producers, and creators. It analyzes and masters WAV or MP3 files locally in the browser, so the audio never leaves the user's device.

The free mastering workflow requires no account, has no watermark, and exports WAV and MP3. Its Gleam Engine V2 combines intelligent analysis, 8-band and dynamic EQ, multiband and glue compression, upward density, stereo processing, multiband saturation, brickwall limiting, and TPDF dithering. Auto mode targets -14 LUFS integrated loudness and a -1.0 dBTP true-peak ceiling.

TrackGleam also includes genre presets, AI-artifact cleanup modes, voice cleanup, reference matching, advanced manual controls, and optional track-specific AI mastering from $1.99. For the optional AI version, only numeric measurements are sent; the audio file itself is never uploaded.
