Finland
What it is
MasterForge is a browser-based audio mastering platform with tools tailored to different genres and aimed in part at artifacts in AI-generated music, 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 signup. Auto-Master uses credits to repair a track, create a mastering plan, and render a 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, podcast, voice, and video, and WAV and MP3 export. Starter is €4.99 per month, Pro is €9.99 per month, and one-off hand-mastering is €14.99. The Progressive Web App can be installed to a home screen or desktop and used offline after initial loading. Free tools and Pro Master process audio on the user’s device; specified server services process uploaded files, which are deleted 90 days after the run finishes.
