MasterForge
MasterForge is a browser-based audio mastering platform with genre-specific tools and options aimed at AI music artifacts such as shimmer, weak bass, stereo artifacts, and flat dynamics. Its free audio analyzer reports an AI audio health score, streaming readiness, shimmer and fog detection, and a 7-band spectrum without requiring signup. Auto-Master uses credits to repair a track, prepare a mastering plan, and render a release-ready WAV; the run page also provides the prepared FLAC and plan. Pro Master includes a real-time DSP engine, AI tools, multiband compression, M/S EQ, a multi-track stem mixer, and platform preview. Supported formats include WAV, MP3, FLAC, OGG, and M4A/AAC. The Free plan includes five masters, AI cleanup, presets for music, podcasts, voice, and video, and WAV and MP3 export. Starter costs €4.99 a month; Pro costs €9.99 a month. The installable Progressive Web App can work offline after its initial load. Free tools and Pro Master process audio on the user's device; server-based services process uploaded audio, which is deleted 90 days after a run finishes for specified services.
