What Sauce Mastering AI is
Sauce Mastering AI is a web service for preparing a finished mix or stems for release. It analyzes loudness, tonal balance, dynamics, low-end, stereo image, and clipping, then offers plain-English suggestions. Its stem element engine can adjust vocals, drums, bass, and instruments, and users can upload their own stems for free. Master controls cover brightness, warmth, punch, dynamics, width, loudness, and true peak, with genre tuning and saved presets. To guide a master, users can upload a reference track or select a built-in preset for matching 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 on each track and says the first master is free, but gives no trial duration. It also lists paid plans, with prices not shown. Vocal Polish and Audio Repair are listed; Stem Separation and Vocal Remover are marked as coming soon.
