Simple, but deadly. Hyper Boost combines a two-band tone control with a hard-hitting soft clipper. Use it early in the chain as a bold saturation effect or throw it on late for subtle, precision mix adjustments. A power-up for your sound. Tone Control - Retro-inspired treble and bass tilt filters. Gentle, not surgical - Adjustable center frequency - Three configurations: Pre (EQ before clipper), Post (EQ after clipper), Emphasis (saturate a frequency band while keeping flat response overall) - Output trim Clipper - Drive input up to +36 dB - Adjustable ceiling and edge for precise control over the clipping curve - Three clipping algorithms: - Juicy: reproduces an infamous stock clipper - Tight: adapted from a classic soft-knee limiter - Hardest: loud and brash hardware-style clipping - Real-time curve visualizer with max peak metering Core Features - Morph Settings for smooth transitions between two complete configurations - Auto Bypass saves CPU when input is silent - AB settings comparison - HQ mode with 4x oversampling and ADAA - One-click loudness matching - All parameters automatable with precise playback - Light and dark interface modes - Internal undo/redo - Auto gain - Use your AUv3 plug-in in a compatible host app or DAW - Standalone app includes support, manual links and in-app purchase options for license purchase Two-week trial included, one-time purchase for full unlock. Unlock your plug-in via in-app purchase from the standalone app or activate in the plug-in using an existing desktop license. Your in-app purchase activates the plug-in on all of your iOS devices. Owners can claim a crossgrade code in the standalone app to receive a discount on a desktop license.

About

BLEASS Spectral Resonator

Transform audio by manipulating its frequency content to create unique spectral textures and resonances. Generate complex harmonic sounds from internal tone generators or MIDI input, with deep control over pitch, timbre, and spectral filtering.

Highlights
  • Spectral domain audio conversion
  • Frequency shifting, blurring, and filtering
  • Internal tone generator and MIDI input
  • Up to eight voices of polyphony
  • Detailed control over resonance parameters
  • Interactive 3D spectrogram visualization
  • Freeze and Kill controls
Read full description

By converting audio into the spectral domain, BLEASS Spectral Resonator can shift, blur, filter, and restructure the frequency content of any sound before generating resonances. When blended with the source signal, this adds a controllable layer of pitch and timbre. Used fully wet, it produces rich and complex spectral textures. Resonances can be generated from an internal four-voice tone generator or directly from incoming MIDI notes. With up to eight voices of polyphony, glide, pitch bend, and up to 256 harmonics per voice, BLEASS Spectral Resonator can be played from MIDI to create tuned harmonic resonances and evolving spectral textures. Intuitive controls provide detailed manipulation of the resonator behaviour, including unison, detuning, harmonic stretching, density, damping, decay, and harmonic filtering. Harmonics can be restricted to even or odd series, while spectral shifting and blurring further reshape the resulting resonances. A spectral-domain filter lets you select the frequency range used to excite the resonators. The interactive 3D spectrogram visualises resonator activity over time while also providing direct control over the spectral filter. BLEASS Spectral Resonator also includes Freeze and Kill controls for holding or clearing active resonances. Designed to combine deep spectral processing with an accessible interface, it opens new possibilities for harmonic, rhythmic, and dynamic sound design, including inharmonic or atonal material such as drums. BLEASS Spectral Resonator is also available for Desktop. Find more information here: http://www.bleass.com/spectral-resonator
