## 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 musical analysis and processing. JAXTranscend is able to modify the frequencies by shifting the pitches of each of the 128 tonal frequency bands across the MIDI note range. The tool is thought for special frequency corrections and creative sound manipulations.

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

- 128 frequency band division
- Chromatic mapping to musical semitones
