Our verdict on KAGE Mastering
KAGE Mastering is a browser-based AI mastering tool for musicians and music producers. Its processing happens locally in the browser, and the Free plan provides unlimited use without a subscription. Users can upload MP3, WAV, FLAC, AIFF, AAC, or OGG files, select a mastering style and intensity, choose loudness targets, and adjust EQ, compression, stereo width, and limiting. The tool also includes a post-mastering parametric EQ with up to 20 bands and exports to WAV, MP3, FLAC, or AIFF.
The strongest fit is for creators who want to master files without sending them to a server. KAGE Mastering states that files remain on the device during processing, which gives the workflow a clear local-processing focus. Its selectable loudness targets include streaming and broadcast presets, while AI audio analysis and style presets provide a starting point before manual adjustments. The combination of format support and detailed controls makes it suitable for users working across common production and delivery formats.
KAGE Mastering is less suitable for workflows built around reference tracks, integrations, or desktop software, since the listed platform is web only and those capabilities are not part of the product description. It is also identified as Version 1.0 Public Beta, so users with production-critical requirements may prefer a more established alternative. Pick KAGE Mastering for free, local, browser-based mastering with control over loudness, tone, dynamics, stereo width, and file format. Choose another tool if desktop coverage, connected workflows, or reference-based comparison is central to your process.
