Sauce Mastering AI vs SongUp AI

Sauce Mastering AI prepares a finished mix or stems for release as a web service. Its processing uses EQ, compression, limiting, and loudness control, with analysis of loudness, tonal balance, dynamics, and stereo image. Mix analysis also checks low-end and clipping and offers plain-English suggestions. The stem element engine can adjust vocals, drums, bass, and instruments; users may upload their own stems for free. Master controls cover brightness, warmth, punch, dynamics, width, loudness, and true peak, with genre tuning and saved presets. For reference matching, upload a track or choose a built-in preset to guide 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 service offers a free preview on each track and says the first master is free. One-time credits and a subscription are listed, but their prices are not shown. Free-tier files may be deleted after 14 days; paid-tier files are retained while a subscription is active.
