Please note, that AudioUnits (AUv3) require a supporting host application to perform. The MBC Pro is a multi band / master bus audio processor (companders), suitable for mastering. Parallel analog modeled filters split the audio stream into 5 freely adjustable bands, on which the 5 dynamic processors will perform action in parallel - each wit its own set of parameters - or linked together. Input and output is stereo, parallel processing for each frequency band (mix with the original) is possible. The effect processors now have zero latency. A PDF manual is included with the app : https://audio.digitster.com/wp-content/uploads/2024/04/JAX-MASTERING-MBC-Pro.pdf This app is truly 'universal', meaning, unit is available for: - MacOS (Silicon) - iOS (iPhone) - iPadOS (iPads) - visionOS (Apple Vision Pro)
