Quantara Music review
A transparent DSP mastering tool for creators who want detailed loudness control.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Quantara Music is a browser-based audio mastering tool for producers and AI music creators who want visible control over the mastering process. Instead of an AI mastering model, it uses a local, adjustable DSP chain with 15 stages. Users can choose genre and platform targets, inspect BS.1770 LUFS and true-peak readings, compare the original with the mastered version, and export WAV files. It accepts WAV, FLAC, MP3, M4A, AAC, AIFF, and OGG files through a web interface.
Pricing supports occasional projects as well as recurring workflows. The Free plan includes three stereo masters per month, WAV and MP3 exports, and loudness matching, with no credit card required. Pro costs €9 per month and adds unlimited mastering exports, reference matching, and higher bit-depth exports. A Single stereo master costs €4.99 as a one-time payment and includes one mastered stereo track, an HD WAV export, and no recurring charge. Studio and Label are also listed plans; Label includes REST API access and WAV 32-bit float export.
The main strength is control rather than automation. Platform-specific loudness targets, 33 genre starting points, adjustable processing, A/B bypass comparison, multi-format WAV export, and local browser processing give users a clear view of the mastering path. Reference-track matching is available on Pro and higher plans, while Label adds REST API access to the account and library for broader workflows. Quantara Music suits creators who want to inspect and adjust loudness-focused mastering decisions. Those seeking an AI-powered, black-box mastering service should choose a different type of tool.
