About

Transient Shaper

This audio plugin offers a simple yet powerful way to shape the attack and sustain of sounds. Its adaptive filters automatically adjust to various inputs, allowing precise control over transient intensity without complex settings. Achieve crisper attacks or soften harshness, and even silence note attacks entirely.

Highlights
  • Adaptive filters for automatic adjustment
  • Precise control over transient intensity
  • Ability to silence note attacks
  • Adjust sustain volume independently
  • Simple, intuitive controls

Blue Mangoo Transient Shaper is a high-quality transient designer effect. The key feature is the simplicity of the controls. The plugin's adaptive filters respond automatically to a wide range of inputs, giving you an extreme level of control over the intensity of transient sounds without the need to adjust complicated settings. The unique filters in the attack envelope allow the attack intensity to be reduced much farther than other transient plugins, to the point of totally silencing the note attack, if desired. EXPLANATION FOR READERS WHO HAVEN'T USED A TRANSIENT SHAPER BEFORE A transient shaper allows you to adjust the speed or intensity of note attacks, making them crispier and snappier, or softening them and reducing harsh click sounds. This is useful if you want to make a snare drum cut through the mix (increase attack) or to soften pick noise on a guitar (reduce attack). Additionally, it allows you to adjust the volume of the sustain (or release) part of a note, leaving the attack part mostly untouched. This is useful if you want to reduce room reverberation sound on drums, making them sound tighter. Usually what we call the "sustain" control actually adjusts the volume of all parts of the sound except for the attack, so in many cases it functions more like a release control than a sustain control, if we compare it to the controls with those names in an ADSR (Attack, Delay, Sustain, Release) envelope control on a synthesizer. WHAT UNIQUE THINGS DOES IT DO? - Adaptive filters handle wide variety of signals automatically without user input - Adaptive filters allow the attack adjustment to respond faster, allowing you to silence even the extreme earliest part of the note Note: except for the unusual ability to totally silence the attack, this plugin does basically the same thing that other transient plugins do. If you already have a transient shaper and you are happy with the way it sounds, this one will sound similar. So the only reasons to buy this are: - You don't have a transient shaper yet - You don't have the Blue Mangoo attack softener plugin yet - You do have a transient shaper but you would like one with simpler controls - You love collecting plugins

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

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).
