GliderVerb vs JAX CHROMATIC
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
GliderVerb
This app offers a unique reverberation effect that simulates a room changing shape, creating evolving soundscapes. It provides a wide range of sonic possibilities, from smooth resonances to granular disintegration, with extensive control over its parameters.
- Continually modulated reverb algorithm
- Pitch resonator
- Ribbon resonance player
- Built-in stereo sampler
- Control manager LFO
- Audiobus and Inter-App Audio support
- Preset morphing pad

GliderVerb is a “Reverberator with Glissandos” simulating a room gradually changing its shape. It is an expanded version of an algorithm created by James McCartney for his Supercollider 2 programming language. The original algorithm had no user-variable parameters: this device adds a series of parameters to create a wide palette of effects; from evolving reverberations to granular disintegration to smooth resonances. Main Features: - Audiobus and Inter-App Audio support (sender and FX) - Continually Modulated Reverb Algorithm - Pitch Resonator - Ribbon Resonance Player - Pad impulse generator - Built In Stereo Sampler with varispeed - Control Manager LFO for Parameters - Midibus, Virtual Midi and Network: 14 bit NRPN controllers - File Manager, sharing common audio files via iTunes, Dropbox and AudioCopy - Snapshots Presets Morphing Pad - Post Fx Chain: Low-shelf Filter, High-shelf and Compressor New Version! We removed the "annoying voice" and now you can use all the Gliderverb features, even the Pad and the Ribbon. The only limitation is you can't save new presets; but you still can load the old ones you made, using the two arrows you find on the left and right side of the preset name (top side of the main window). With the in-App purchase you can access the Preset Manager, Control Manager and MIDI enable the Pad.
JAX CHROMATIC
This advanced audio processor splits sound into 32 frequency bands for real-time spectral dynamics modification. It enhances sound perception, removes muddiness, and offers a user-friendly interface for creative mixing and mastering.
- 32-band spectral processing
- Real-time compander per band
- Analog filter models
- Latency-free operation
- Mastering and mixing tool
- User-friendly interface

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.

Verdict
The clearest difference is price: GliderVerb at Free against JAX CHROMATIC's $12.99. GliderVerb also leads on update cadence (every 4 months vs every 14 months) and ratings volume (85 vs 7). JAX CHROMATIC's advantage is in-app purchases (none vs 2) and rating (4.9 vs 4.6). On ads there is nothing between them.

GliderVerb is free to download; JAX CHROMATIC costs $12.99 up front. GliderVerb sells 2 one-off in-app purchases. JAX CHROMATIC asks for nothing beyond the download.
JAX CHROMATIC holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: GliderVerb has 85 ratings behind it against 7, so its average is the more settled of the two. Written reviews point the same way: 80% of GliderVerb's written reviews are positive against 100% of JAX CHROMATIC's.
GliderVerb ships an update every 4 months, JAX CHROMATIC every 14 months. Both last shipped on September 22, 2026.
