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.

About

BLEASS Multiband Compressor

BLEASS Multiband Compressor is the perfect tool for injecting loudness, power and punch into your mixes, stems and tracks. Whether you are creating music on-the-move on your iPad, producing your masterpiece in the studio, or doing both, BLEASS Multiband Compressor dispenses detailed precision control over your music's dynamics. One of the secret weapons of professional mix and mastering engineers, multiband dynamics processors have various advantages over conventional broadband processors. By separating your audio into three frequency bands, and processing each independently, BLEASS Multiband Compressor ensures that loud passages and transients in one frequency range do not impact on how the other bands behave. This eliminates the "volume pumping" effect often exhibited by broadband compressors, making BLEASS Multiband Compressor the perfect tool for processing drum kits, synths, pianos and – of course – full mixes and stems. The plugin works brilliantly with other sources too, from solo instruments to vocals and spoken voice. Unusually for a multiband processor, each of BLEASS Multiband Compressor's three bands features a dual stage dynamics processor. This consists of an Above stage that senses for and processes signals whose level exceeds the Above threshold, and a Below stage that senses for and processes signals that are quieter than the Below threshold. Additionally, each stage can operate as either a compressor or, by dialing in Ratio values below 1:1, an expander. Altogether this makes for phenomenally versatile control over the volume and loudness of your mixes, stems and parts. Another innovative feature of BLEASS Multiband Compressor is its flexible sidechain system. This allows you to choose which bands will key from the input signal in the normal way, and which will key from a filtered and/or external signal. This is ideal for corrective work such as controlling resonances, sibilances and other unwanted artefacts, but is also a fabulous creative tool, allowing for stylish ducking effects and ultra-deep dynamics control. Rounding things off, the plugin provides comprehensive output level and dry / wet balance control, along with a soft clipping feature that ensures overly-hot signals don't become nasty and harsh, but instead take on a classic valve-like saturation character. BLEASS Multiband Compressor stands out for its great sound, innovative features, versatile dynamics control, and exceptional efficiency.
