Global Finalizer for your Master Sound

Mastering Tool is an Audio App for Mastering intented to audio content creators available for macOS® systems*

« Mastering Tool » App for Audio Mastering

Mastering Tool is a standalone macOS® audio utility intended to audio content creators. It includes 3 essential & global real time modules for audio files treatment : « The Infinite Wheel », the « Beast Equalizer » and the « Master Limiter » (Developed with the Apple® AVAudioUnit technologies).

Most of the time during the audio or musical creation process the designer focuses on sound under specific listening conditions (professional studio speakers) with a purely artistic goal. A good mix or recording generally does not exceed a certain sound level (-6dB RMS) even sometimes less (-15dB RMS). “Mastering Tool” is an App that helps to calibrate audio files for a professional sound closer to your maximum level (eg 0 dBFS, -10 dBFS, -16 LUFS…).
