Sauce Mastering AI
What it is
Sauce Mastering AI is a web service for preparing finished mixes or stems for release. Its processing uses EQ, compression, limiting and loudness control, and analyzes loudness, tonal balance, dynamics and stereo image. Mix analysis also covers low-end and clipping, then provides plain-English suggestions users can apply. The stem element engine can adjust vocals, drums, bass and instruments; users may upload their own stems for free.
Users can change brightness, warmth, punch, dynamics, width, loudness and true peak, enable genre tuning and save presets. Reference matching uses an uploaded track or a built-in preset to match loudness, tonal balance, stereo width and energy. Release exports are available as WAV, FLAC and MP3. Uploads can be WAV, MP3, AIFF, FLAC or M4A, up to 15 minutes. The site offers a free preview for every track and says the first master is free; no trial duration is stated. One-time credit and subscription plans are listed, but their prices are not shown. Producersources is identified as the creator. Stem Separation and Vocal Remover are marked as coming soon.
