Studio quality reverb for AUv3 compatible hosts / Audiobus / Inter-app audio and songs from your iTunes music library. AudioReverb is an algorithmic reverberation app which combines the flexibility of vintage algorithmic reverbs with the sonic quality of convolution based reverbs. The creation of high quality reverb needs a realistic simulation of the important early reflections together with a smooth and colorless reverberation tail. The early reflections are the most important clue for the human ear to get a feeling about the dimension and character of a room. Most algorithmic reverbs offer a number of different algorithms to simulate different natural rooms like chamber, halls or artificial ones like plates. AudioReverb uses impulse responses from real acoustic spaces and classical reverb algorithms to emulate their acoustical properties. The resulting reverberation sets new standards in clarity and sense of space ! Use AudioReverb for enhancing your listening experience with your favourite iTunes songs. Use AudioReverb as professional reverb plugin to improve the quality of any Audiobus or Inter-app audio compatible App. • Smooth reverb tail generation. • Early Reflection Modelling. • 118 factory presets. • 4 Band Equalizer. • AudioUnit for AUv3 compatible hosts. • Inter-app audio compatible effect. • Audiobus 3 compatible as effect. • Reverberate any song in your iTunes library. • Low latency live usage with mic and headphones. • Audio recorder. • Audio file export via pasteboard / open in / e-mail
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.
- 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

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).
