What it is

StudioZIO Mastering Suite is a free macOS mastering application that combines tonal shaping, dynamics, stereo control, and delivery metering in one signal path. Its nine stages are M/S engine, saturation, Pink Match, glue, maximizer, tone EQ, clipper, limiter, and output. Pink Match listens for twenty seconds against a target curve, then applies correction at the amount selected by the user. The limiter’s true-peak detector uses 16× reconstruction; separate true-peak meters use 4× reconstruction. Loudness displays include integrated, short-term, and momentary LUFS plus true peak in dBTP. The suite is available as Audio Unit, VST3, AAX, and a standalone application, working with hosts that load those formats; AAX was validated in Pro Tools. The current release supports macOS 11 or later on Apple Silicon and Intel Macs. Installation is Developer ID signed and Apple notarized, and a SHA-256 checksum is published. No licence key or account is needed. There is no Windows or Linux build planned, and uninstalling requires removing installed files and rescanning the host.
