BLEASS’ Spectral Resonator plugin transforms audio into spectral layers with over 250 playable harmonics

BLEASS has launched a new plugin, the Spectral Resonator, which lets users transform vocals, synths, drums, guitars, and more into spectral layers with up to 256 playable harmonics.

The plugin works by converting your signal into the spectral domain, where it then applies creative effects. The spectrum can be shifted, blurred, and de-structured, with decaying tails and harmonic filtering. When blended with the source signal, this adds a controllable layer of pitch and timbre to your sound.

BLEASS says that the sound produced by Spectral Resonator is not dissimilar to a vocoder, but “extends beyond the confines of that classic effect into the realms of harmonic delays and tuned reverberations”.

Its internal generator can produce up-to four tunable voices, and can be used as the basis of the resonators’ frequencies. Alternatively, these pitches can be derived from incoming MIDI notes, so you can essentially play Spectral Resonator like a synth, with up to eight voice polyphony, glide and pitch-bend.

As with other BLEASS tools, the plugin champions an interface that is simple to use and allows for deep control. Users can experiment with principal resonator settings via rotary controls, while a rainbow spectrum analysis display doubles-up as a means of controlling the integrated filter.

The plugin also features a Freeze button, which holds the resonators in their current state, and a Kill button, that immediately stops any hanging resonances.
