About SonicFuss

Created by Theophilus Benjamin.

A free mastering prototype with local EQ, compression, limiting and WAV export. Audio processing and analysis run on your device.

Build 0.1 · Private testing only. This is not a certified loudness or true-peak meter. Source warning detection is heuristic; it cannot identify or repair every distorted recording.

Original implementation. No runtime third-party libraries, analytics or external assets. Read processing methods and licence.
