KAGE Mastering

What KAGE Mastering is

KAGE Mastering is a browser-based audio mastering studio that processes files locally; the product page says audio is not sent to a server. It accepts MP3, WAV, FLAC, AIFF, AAC, and OGG files. Users can choose from styles such as Balanced, Warm, Bright, EDM, Hip-Hop, and Acoustic, with intensity ranging from Subtle to Maximum drive. Loudness targets cover YouTube, Spotify, Apple, Tidal, Amazon, Broadcast, and EBU R128, or can be set custom. Manual controls include EQ bands, stereo width, and compressor settings. A separate parametric EQ after mastering supports up to 20 bands, including Bell, LowCut, HighCut, shelf, Tilt, and Notch types. The page says loudness measurement uses BS.1770-4 integrated loudness with gated, K-weighted measurement. Exports are available in WAV, MP3, FLAC, or AIFF; WAV supports PCM or float with selectable sample rate and bit depth. It runs on the web and is identified as Version 1.0 Public Beta. The Free plan costs nothing.
