What MasterForge is

MasterForge is a web-based audio mastering platform with tools for different genres and audio cleanup aimed at artifacts such as shimmer, weak bass, stereo issues, and flat dynamics. Its free analyzer reports an AI audio health score, streaming readiness, shimmer and fog detection, and a 7-band spectrum, with no signup required. Auto-Master uses credits to repair a track, prepare a mastering plan, and render a WAV; the run page also provides the prepared FLAC and plan. Pro Master adds a real-time DSP engine, AI tools, multiband compression, M/S EQ, a multi-track stem mixer, and platform preview. Supported formats are WAV, MP3, FLAC, OGG, and M4A/AAC. The free plan includes five masters, AI cleanup, presets for music, podcasts, voice, and video, plus WAV and MP3 export. Starter costs €4.99/mo and Pro costs €9.99/mo. Free tools and Pro Master process audio on your device; server-based services process uploaded audio, which is deleted 90 days after a run finishes. The app can be installed and used offline after it initially loads.
