The JAX DYNAMICS : Compressor is a single band dynamics audio processor and supports different stereo operation modi (like independent stereo, linked stereo, independent mid/side and linked mid/side processing) and has a parallel processing option (mix) too. The JAX Compressor is a dynamics processor in AudioUnit (AUv3) format. The audio unit itself (an app extension) is embedded into a small demo app. This is required for app distribution on Apple platforms. Installing the app will make the audio unit available for system wide usage with audio unit hosts (music apps), which support loading 3rd party app extensions in AUv3 format. There is a manual for our Dynamics Series Basic located at : https://audio.digitster.com/jax-dynamics-compressor A basic demonstration video for the dynamics series can be seen here : https://youtu.be/hOwM1t6jYes?si=gqlpp6oQRXtUuj8V This app is truly 'universal', meaning, unit is available for : - MacOS (Silicon) - iOS (iPhone) - iPadOS (iPads) - visionOS (Apple Vision Pro) Please note, that AudioUnits (AUv3) require a dedicated supporting host application to perform.

A vintage-inspired delay supercharged with deep modulation, flexible filtering, and creative timing that pushes echoes into new dimensions. This is the free Lite version of Quantum Delay. Enjoy it? Go pro with the full version. Classic Delay, Reinvented Quantum Delay Lite takes the charm of a vintage stereo delay and fuses it with our next-level modulation system. Switch between the warm character of Tape mode and the pristine clarity of Fade mode, lock to BPM (including 5-tuplets) or dial in precise times in milliseconds. Use the Fine control for subtle push-and-pull micro-timing — or modulate your delay lines in ways traditional delays could only dream of. Sculpted Echoes Shape your repeats with a lowpass filter placed directly in the feedback path. Add modulation to create evolving tones, gentle movement, or drifting, frequency-shifting echoes. From warm analog-style rolls to shimmering, swirling textures, it’s all there. Feedback with Precision Control your delay tail behavior using either traditional % feedback or our modern dB-per-second decay system — ideal for predictable, musical decay even when the feedback path becomes complex. Enable Crossfeed for classic ping-pong stereo bounce, or push into Over-Feedback to create dense, self-building echoes that drift toward infinity. Modulation Without Limits Quantum Delay Lite integrates our advanced modulation system, letting you modulate nearly anything: delay time, filters, feedback parameters, and more. Use LFOs, Random Generators, 2D modulators, Envelope Followers, Macros, and even chaotic systems to push your echoes far beyond traditional delay behavior. Or use our parameter randomisation feature to explore the plugin’s sound at random. Quantum Delay Lite is an AUv3 audio effect plugin compatible with Logic Pro, AUM, Cubasis, GarageBand and many more. A Desktop version is also available for Windows and macOS (VST3 / AU / AAX).
