BLEASS Vox is your gateway to effortless sonic manipulation. This cutting-edge processor immerses you in a world of sonic possibilities, effortlessly shaping every nuance of your vocal performances. Formant processing lets you alter the perceived character of a voice independently from its melody, opening up everything from natural tonal variations to dramatic vocal transformations. The Unison processor can spread up to 10 detuned voices across the stereo field, adding width, depth and weight without requiring a complex vocal processing chain. Vibrato adds controlled pitch movement for anything from gentle modulation to more pronounced special effects, with immediate hands-on control. BLEASS Vox includes two processing modes for different workflows. Real-time mode prioritizes speed and responsiveness for recording and live performance, while Standard mode delivers the accuracy needed for editing and mixing. BLEASS Vox can be used as an AUv3 plugin or standalone app on iPhone and iPad. BLEASS Vox is also available for Windows, macOS and Linux.

Features
Read full description

A vintage-inspired delay supercharged with deep modulation, flexible filtering, and creative timing that pushes echoes into new dimensions. Classic Delay, Reinvented Quantum Delay 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 switchable lowpass, highpass, and bandpass filters 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. Stereo or Dual Mono Every section of Quantum Delay — delay, filter, and feedback — can switch between stereo and dual mono modes. Create tight, controlled stereo images or break them apart for wide, offset, unpredictable spaces. Dual mono modulation unlocks complex stereo interplay and beautifully asymmetric echoes. Modulation Without Limits Quantum Delay integrates our advanced modulation system, letting you modulate nearly anything: delay time, filters, feedback parameters, stereo controls, 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 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). More information here: https://gs-dsp.com/products
