( THIS IS AN AUDIOUNIT. AudioUnits are app extensions, requiring any audio host application to perform. ) Use the same AudioUnits across all modern Apple devices, including the iPhone and the Mac (Apple Silicon). Native MacOS apps like GarageBand, MainStage 3 and Logic Pro X are fully supported. Any 3rd-party AUv3 supporting host should be able to host the plugin too. The JAX ESSENTIAL SERIES Phaser is a multi stage phaser modulation effect that uses multiple allpass filters, to produce all kinds of the famous phaser effect. A low frequency oscillator modulates depth and speed of the filter modulation on both stereo channels for various living and moving sound nuances. Make static sounding voices more interesting or create sweaping special effects. You may share the presets for this effect across all your supported devices. Around 200 factory presets are included, you can make and export/import your own. The complete manual is included and can be previewed on our support website: https://audio.digitster.com For advanced usage (i.e. mastering and exciting), we recommend to select the phaser from our SELECTIVE RANGE SERIES, which allows to limit the frequency range for processing. This build is truly 'universal', meaning, the audio unit is available for: - iOS (all actual iPhones) - iPadOS (all actual iPads) - macOS (Apple Silicon) - visionOS (Apple Vision Pro) Requirements: MacOS 11.0++ iOS 14.0++ Behaviour on all devices is identical. The parametric interface is resizeble and adopts to any screen size and orientation. This especially applies to Logic Pro X and all hosts with adjustable window sizes on all platforms. Display contrast can be adjusted freely and is now saved with each preset.

About

GSDSP Quantum Distortion

Explore four distinct distortion effects—Saturation, BitCrush, Ring Modulation, and Downsampling—blended and controlled via an intuitive XY pad. Shape harmonics, reduce digital resolution, introduce inharmonic motion, and create classic digital degradation for unique audio textures.

Highlights
  • Four distortion algorithms (Saturation, BitCrush, Ring Modulation, Downsampling)
  • Intuitive XY pad for blending effects
  • Custom waveshaping saturation
  • BitWarp for tonal variation
  • Tunable oscillator for ring modulation
  • Adjustable downsampling rate and jitter
  • AUv3 audio effect plugin

Read full description

Four complementary distortion algorithms — Saturation, BitCrush, Ring Modulation, and Downsampling — blended and shaped through an intuitive XY pad. Saturation Shape harmonics using Quantum Distortion’s custom waveshaping saturation. Adjust Drive to set the intensity from subtle warmth to strong coloration, and use Asymmetry to introduce controlled even-harmonic emphasis of vintage tube characteristics. BitCrush Reduce digital resolution using BitCrush and reshape the crushed signal with BitWarp, which bends the quantization curve for additional tonal variation. This combination allows precise control over both the amount of reduction and the character of the resulting digital artifacts. Ring Modulation Introduce inharmonic motion using ring modulation, generated by multiplying the input with a tunable oscillator. Adjust frequency and amount in real time to create anything from light metallic shading to dense, shifting sidebands. Downsampling Lower the sample rate using Downsampling, reducing temporal resolution for classic digital degradation effects. Set the rate down to 200 Hz or introduce Jitter for controlled randomness, adding instability and movement to the downsampled signal. XY Pad Blending Navigate between the four distortion algorithms using the XY pad, allowing smooth transitions or static blends across the processing modes. The background updates to reflect the current region, providing clear visual feedback while exploring hybrid distortion shapes and interactions. Quantum Distortion 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).

Verdict

The call

The clearest difference is price: JAX ESSENTIALS at $4.99 against GSDSP Quantum Distortion's $14.99. JAX ESSENTIALS also leads on update cadence (every 2 weeks vs every 5 weeks). GSDSP Quantum Distortion's advantage is ratings volume (10 vs 1) and iOS requirement (12.0 vs 14.0). On rating, ads, in-app purchases and monetization model there is nothing between them.
