01Overview

BLEASS Spectral Resonator goes beyond a conventional vocoder. It analyzes incoming frequencies and rebuilds them as shimmering harmonic banks, with harmonic shaping tools such as Stretch, Shift, Density, Blur and Unison with Detune. Harmonic filtering lets you keep all, even or odd harmonics. The plugin can be driven by audio or by its internal 4-voice generator, or played via MIDI. It is aimed at producers who want anything from subtle enhancement to animated, otherworldly textures.

Spectral Shaping and Sound Character

The core of Spectral Resonator is its harmonic processing. Each voice can generate up to 256 harmonics, and the Stretch, Shift, Density and Blur controls reshape that spectrum over time. Unison with Detune adds width and movement, while the All, Even and Odd filter modes let you favor particular harmonic families.

Used lightly, the plugin can add depth and body to a signal. Pushed further, the developer describes it as capable of dramatic, animated results, which makes it suitable for ambient and experimental sound design.

Performance, Freeze and Visual Control

The Interactive 3D Rainbow Spectrogram shows the spectrum in real time and doubles as a control surface: moving within it also adjusts the spectral filter. Freeze and Kill functions provide instant performance moves, holding a spectral snapshot or cutting it off immediately.

For note-based playing, the internal 4-voice generator can be replaced by full MIDI control with up to 8-voice polyphony, glide and latch.
