MasterForge vs Matchering

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.

Matchering is open-source software for matching and mastering audio. Give it a TARGET track and a REFERENCE track, and it produces a mastered TARGET that follows the reference’s RMS, frequency response, peak amplitude, and stereo width. Matchering 2.0 comes as a containerized web application, Python library, and ComfyUI node, and is integrated into the UVR5 Desktop App. The Python library also provides a command-line application and can connect with the Python ecosystem. It requires Python 3.8.0 or later and a machine with 4 GB of RAM. WAV and MP3 are supported input formats, though MP3 loading needs a separate FFmpeg installation. The project says the algorithm uses digital signal processing rather than a neural network, and works well across nearly all genres, especially EDM, with an exception for experimental music with a very specific form. The free plan is listed at free under GPLv3, with no published paid plans. The maker advises against exposing its web application to the public Internet without security and scalability changes.
