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.
Weeping Wall
This app creates evolving soundscapes by automatically recording and layering new audio input into independent microloopers. It offers extensive controls for loop size, repitching, and randomization, allowing for unique sonic textures. Designed as a modular tool, it integrates seamlessly with other audio effects for creative sound design.
- Automatic microloopers with input detection
- Independent loopers with variable size
- Repitching and reverse controls
- Jitter control for random variations
- Beat and transport syncing
- Live performance mode
- Modular tool for creative sound design

Weeping Wall is a standalone app and AUv3 plug-in. WW is a set of microloopers that automatically record based on input detection. Each new sound will be smoothly introduced and replace older sounds, resulting in a group of sounds that always reflect the most recent input. Each looper behaves independently - their size can vary and they will beat against each other as they phase. Up to 5 loopers are available to record into, with repitching and reverse controls as well. A dedicated “jitter” control allows you to randomly vary the size of each looper on each loop, creating variations that will never be heard again. Weeping Wall can be used as an effect directly on a track, or as a send effect. WW is intended to be a modular tool; it doesn’t include reverb, EQ, saturation, flutter, etc., but it plays extremely well with them. WW is a brand new effect that can be used in any number of creative ways - you can place it fully wet in front of a reverb, place a hint of it behind a saturator, combine it with your favorite pitch modulation - whatever you can dream. WW is fully compatible with automation and modulators such as Ableton CV to broaden the horizons even further. Weeping Wall has the following controls available: Threshold: The volume at which input will start recording into a looper. Looper size: The size of loopers, in seconds, from 0.1s to 3s. Jitter: A control for desynchronizing loops. Loops will be randomly shortened, and each one is free to change size independent of one another. Semitones: Repitch loops, with a range of +/- one octave. Reverse: A latching control to reverse looper playback. Looper number: Up to five loopers are available. Hold time: How long loops will be held before fading away, from seconds to forever. This essentially controls whether WW functions more as a looper or as a delay. Independent dry and wet volumes: Use WW as an effect directly on your track, or as a send effect. Beat syncing: Loopers can be synced to your tempo, from 1 whole measure to 1/64th notes. Macro-looper mode: Loops can grow to up to 60 seconds in length. Transport syncing: Loopers can be paused or destroyed on pause. Live performance mode: Enables a button-based UI designed with live performance in mind. Random skip: Loops can be randomly skipped over with some probability. Crossfade length: Control the length of the crossfade occurring at the start/end of each loop to keep sharper transients or smooth them off. Fade time: Control how long loops take to fade in/out. Filters: The wet channel can be high or low pass filtered for dialing in your sound.

Verdict
The clearest difference is update cadence: Weeping Wall at monthly against JAX CHROMATIC's every 14 months. Weeping Wall also leads on price ($8.99 vs $12.99) and ratings volume (36 vs 7). On rating, review sentiment, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
JAX CHROMATIC costs $12.99 and Weeping Wall $8.99 up front. Neither carries in-app purchases, so what you see is what you pay.
On the App Store both sit at effectively the same score — 4.9 for JAX CHROMATIC against 5.0 for Weeping Wall. That said, the two scores are not equally well evidenced: Weeping Wall has 36 ratings behind it against 7, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
JAX CHROMATIC ships an update every 14 months, Weeping Wall monthly. The most recent releases landed on November 3, 2026 and November 4, 2026 respectively.
