In their own words
Sauce Mastering 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.
WhitePrint AudioEngine
WhitePrint AudioEngine provides AI-powered audio analysis and mastering through a web interface and API, returning analysis data, mastered audio, or both. Its BS.1770-4 analysis measures LUFS, true peak, loudness range, crest factor, spectral balance, and stereo width. Three independent AI models make mastering recommendations, and users can inspect each model's advice and the reasoning behind the consensus. The mastering chain has 14 hybrid DSP stages, bypassed by default unless the AI directs otherwise. Users can compare original and mastered audio with an A/B player, inspect metric changes, and download a WAV file. WAV and FLAC inputs are supported, and direct processing can use links from Google Drive, Dropbox, OneDrive, Amazon S3, and Google Cloud Storage; Suno and SoundCloud are also listed as URL sources. API routes support full mastering, analysis-only, deliberation-only, and DSP-only tasks. Submitted audio is deleted within 24 hours after job completion and is not used to train AI models. The free plan includes three WAV masters monthly and seven days of analysis history. Paid plan prices range from $54 a month to $5,506 a month.
