Voice bot is a real time channel vocoder. A vocoder takes the spectral information of one sound also known as a modulator and uses it to shape another sound called a carrier. The resulting sound is a bit like a singing robot. Use the microphone to play live or record your own loops for playback, with a few different trigger modes using the keyboard. Further process the sound with a bit and sample crusher, delay and flanger. Play with the built in 25 key dynamic keyboard or using core MIDI with options for MPE. Run voice bot stand alone on iPad and iPhone or as a AUv3 plugin in your favourite host. Connections to other apps are also available through Audiobus and Inter Appp Audio. +++ Microphone input +++ Vocoder with up 128 filter bands +++ Polyphonic carrier source or Mono with glide settings +++ Built in 3 Oscillator carrier source, with saw, square and noise shapes +++ Record or import carrier sample loops +++ Freeze spectrum +++ Bit and sample rate crusher +++ Pitch tracking using Yin algorithm +++ 4 tap stereo delay +++ flanger +++ Multiple sample loop trigger modes +++ 25 key dynamic keyboard +++ Core Midi, Bluetooth Midi, Inter App Audio Midi and AUv3 MIDI +++ Midi CC available for all audio parameters +++ Limited MPE Midi support +++ Modulateble parameters: bands, bit crush, sample crush, delay feedback, flanger mix, vibrator and pitch bend
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).
