Alternatives to AI Mastering

{"intro": "AI Mastering is a free mastering service for improving music sound quality with automatic processing. Its limiter balances loudness and dynamics, while the web interface lets you set target loudness, mastering level, output format, and bass preservation. Spectrum and loudness analysis support review, and reference-track matching helps guide results. WAV, MP3, and MP4 are accepted, with WAV export. You can use the service through web, mobile, desktop, API, extension, Linux, macOS, Windows, or self-hosting options.\n\nAlternatives become relevant when AI Mastering’s online waiting, input formats, or free-only pricing do not fit a project. The maker says online waiting cannot be shortened, although its offline version uses computer memory for maximum file size. Other services add genre profiles, stem adjustment, detailed mix feedback, local processing, open-source deployment, or broader export choices. Compare those workflows with your preferred platform, file limits, reference matching, analysis, privacy approach, and whether a paid plan is acceptable.", "rows": [{"ref": "sw:roex-mastering", "name": "RoEx Mastering", "best_for": "Reference matching with local Mac processing", "pricing": "Free preview; paid download; free trial", "key_difference": "RoEx adds genre profiles, LUFS choices, and local Mac processing alongside reference matching.", "choose_when": "Choose it for free previews, specified loudness targets, or offline Mac mastering without uploads."}, {"ref": "sw:sauce-mastering-ai", "name": "Sauce Mastering AI", "best_for": "Stem-aware mastering and mix suggestions", "pricing": "Paid; free plan and free trial", "key_difference": "Sauce adds stem adjustment, plain-English mix suggestions, presets, and Vocal Polish and Audio Repair tools.", "choose_when": "Choose it when vocals, drums, bass, instruments, or broader mix feedback need separate attention."}, {"ref": "sw:whiteprint-audioengine", "name": "WhitePrint AudioEngine", "best_for": "Explainable analysis and API pipelines", "pricing": "Free plan; paid from $67/mo; 14-day trial", "key_difference": "WhitePrint exposes three models’ reasoning, detailed BS.1770-4 metrics, and multi-route API mastering.", "choose_when": "Choose it for explainable recommendations, cloud-storage links, or integration into DAWs, platforms, and CI/CD."}, {"ref": "sw:auralith-forge", "name": "Auralith Forge", "best_for": "Adaptive mastering with creative previews", "pricing": "From €9.99/mo; free plan and free trial", "key_difference": "Auralith adds artist profiles, codec previews, stem separation, unlimited analysis tools, and importable JSON chains.", "choose_when": "Choose it for level-matched comparisons, codec checks, broad upload formats, or manually defined processing chains."}, {"ref": "sw:matchering", "name": "Matchering", "best_for": "Open-source reference matching", "pricing": "Free plan", "key_difference": "Matchering is open source and matches a target to a reference’s RMS, frequency response, peak, and stereo width.", "choose_when": "Choose it for self-hosting, Python or command-line integration, ComfyUI, or UVR5 desktop use."}, {"ref": "sw:trackgleam", "name": "TrackGleam", "best_for": "Local browser mastering on mobile", "pricing": "Free plan; paid from $1.99; 3-day trial", "key_difference": "TrackGleam processes audio locally, supports video inputs, and offers five GleamAI mastering directions.", "choose_when": "Choose it for Android or iOS browser work, watermark-free downloads, or privacy-focused local processing."}, {"ref": "sw:engineer-guy-ai-master-track", "name": "Engineer Guy AI Master Track", "best_for": "Fast mastering with coaching feedback", "pricing": "Free plan; Pro and Studio features; free trial", "key_difference": "Engineer Guy adds streaming targets, Mix Coach feedback, and stem separation alongside reference matching.", "choose_when": "Choose it when mix guidance, explicit platform loudness targets, or vocal, drum, bass, and instrument stems matter."}]}
