## What is JAX SPECTRO Series?

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.

## Key features

- Real-time spectral analysis
- 128 frequency bands
- Chromatically mapped bands
- Musical semitone scale visualization
- MIDI note range coverage
- Universal build for Apple devices
