Matchering vs SoundBoost.ai

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.

SoundBoost.ai is an online audio mastering service for musicians, artists, and producers. It combines deep learning with LLM technology, letting users describe desired sound changes in natural language. The service also splits audio into vocals, drums, bass, and instruments; Unlimited Plus adds guitar and piano channels. Unlimited and Unlimited Plus include reference mastering. Finished masters can be downloaded as 24-bit WAV or 320 kbps MP3, and SoundCloud tracks can be imported by link. The free plan provides 10 revisions per project but does not allow finalizing or downloading. Free stem-splitting uploads have no daily or monthly count quota, though each file is limited to 1.5 GB and 22 minutes 30 seconds. Unlimited is listed at $48 a year, billed annually. One subscription works across the web, iPhone, iPad, and Android. Users retain ownership of their music and may monetize masters. SoundBoost says it does not train its AI on users' audio or share music with third parties without consent.
