Note: AudioUnits (AUv3) require a supporting host application to perform. JAX SPECTRO SERIES AudioUnits (AUv3) are special spectral processors, which divide the audio stream in 128 frequency bands. These bands are chromatically mapped and visualized consequently in the scale of musical semitones across the entire MIDI notes range. These tools are useful for frequency analysis in a musical context. This build is truly 'universal', meaning, unit is available for: - MacOS (Apple Silicon) - iOS (iPhone) - iPadOS (iPads) - visionOS (Apple Vision Pro) Please note, that the MacOS Catalyst (Intel) versions may be sold separately, as the AppStore does not allow to bundle none-silicon apps.
