In their own words
AI Mastering
AI Mastering is an online service that uses AI to master audio with the aim of improving music sound quality. Its limiter can balance loudness and dynamic range, while the web interface lets users set target loudness and mastering level. It also supports drag-and-drop uploads, output-format customization, spectrum analysis, and loudness analysis. The API supports audio upload and download, mastering, and changes to target loudness and mastering level; its documentation links JavaScript (Node) and Ruby client libraries and tutorials. An offline desktop version is available, and the maker says its focus is shifting toward that version rather than the API. Offline file size depends on the computer’s memory, while the online service has file limits. The maker says online waiting time cannot be shortened and suggests using the offline version to reduce it. A bass-preservation option can reduce low-frequency attenuation. Supported input formats are WAV, MP3, and MP4, and WAV export is available. The free plan lists unlimited mastering, and users retain control over their mastered tracks without service restrictions.
