AI Mastering vs Loudly

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.

Loudly is a web-based AI music generator from a maker headquartered in Berlin, Germany. It supports vocal generation, audio uploads and stem export, with downloads in MP3 and WAV formats. Commercial use is supported, so listed rights cover commercial projects. The Free plan costs nothing and limits generated tracks to 30 seconds. Personal includes AI music generation, downloads and commercial licensing. Pro lists higher generation, download and stem allowances, also with commercial licensing. Because the listed platform is web, the service is accessed through a browser rather than a separately listed desktop or mobile application. Audio upload and stem export provide ways to incorporate existing material and separate generated parts. The defined free-track duration gives the no-cost option a clear boundary, while the paid plan descriptions indicate expanded allowances and licensing for users who need more output.
