This is an AudioUnit. AudioUnits (AUv3) require a supporting host application to perform. The main app distributes the embedded unit and allows for testing with random sound samples. The complete manual can be found at: https://midi.digitster.com/CHROMATIC/JAX%20CHROMATIC%20Compander.pdf There is also an introductory video available at: https://www.youtube.com/watch?v=TlEGn_npt4A The JAX Chromatic Compander is an advanced real-time spectral dynamics processor, which splits the audio stream internally into 32 separate, stereophonic, chromatically tuned frequency bands. The parallel bandpass filter bank consists of fast response analog fiter models, producing natural fading sound with no latency. Chromatic means, that each bandpass is adjusted to cover 4 halftones in a musical scale (analog a classic 3rd octave). In difference to a 'Bark' filter, the chromatic bandpass filters are mapped consequently to the musical scale thru the entire frequency range. A bi-directional stereophonic dynamics processor, based on the compander (a combination of an expander and a compressor), is attached to each of the 32 frequency bands and will perform spectral dynamics modification in time with specified attack and release values. The JAX Chromatic Compander can be seen as a unique spectral enhancer, that is able to drastically improve the perception and presence of sound, especially removing all mud. It is mainly recommended to be used as a mastering processor, psycho acoustic loudnes maximizer and creative mixing tool for any kind of wideband audio signals (i.e. complete mixes and all sonically rich audio materials). We use vector processing CPU registers on all supported platforms for keeping the performance as good as possible. There are in sum 64 filters, 64 companders and 64 input- and output mixers performing in parallel thousands of instructions for each single audio sample of the continuous input stream. Usage, on the other side is extremely simple. All parameters are adjusted with ease by just moving fingers over the touchsreen. There is one macro knob for adjusting the compression/expansion amount. We spared out all complicated editing with numerical input and such, making JAX Chromatic Compander a joy to use. Our latest builds are truly 'universal', meaning, the AudioUnit is available on: - MacOS (Catalyst Intel) - MacOS (Silicon M1/M2/M3...) - iOS (iPhone) - iPadOS (iPads) Please note, that the MacOS Catalyst versions may be distributed or sold separately, because the AppStore does not allow to bundle none-silicon apps for the Mac with the iOS apps. Our builds come with latest technology support for all Apple devices. We therefore always develop with currently actual frameworks and compilers.
