Auralith Forge vs Matchering

Auralith Forge is a web service for automated music mastering. Its adaptive DSP measures loudness, tonal balance, dynamics, and stereo width before applying processing such as EQ, compression, saturation, and true-peak-safe limiting. Users can make instant level-matched A/B comparisons, use artist profiles, and preview codecs; stem separation is available as an option for rebalancing vocals and accompaniment separately. Free accounts also get unlimited chord, key, BPM, chord-progression, and LUFS analysis tools. Uploads can be up to 200 MB in WAV, AIFF, FLAC, MP3, M4A, AAC, OGG, WMA, MP4, or WebM, with WAV or MP3 exports. The Free plan includes three full-length masters once and unlimited 30-second previews. Paid options include a one-time extra master for €2.99, Indie at €4.99 per month, Studio at €9.99 per month, and All-Access at €19.99 per month. The Professional engine, included with Studio and All-Access, adds separate sub and punch bands and a transient-aware clipper. Uploaded audio, masters, and codec previews are deleted from servers 48 hours after creation.

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.
