BLEASS Spectral Resonator conjures an iridescent palette of resonating harmonics that add colour, texture and contrast to your audio. Whatever the input, the results are rich, expressive, and deeply enchanting.

The sound produced by BLEASS 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. BLEASS Spectral Resonator converts your signal into the spectral domain, where it applies a range of creative effects. The spectrum can be shifted, blurred, and destructured, with decaying tails and harmonic filtering. When blended with the source signal, this adds a controllable layer of pitch and timbre to your sound. Alternatively, replace the source entirely and let BLEASS Spectral Resonator take over with its rich, complex textures at full wet.

An internal generator, capable of producing up-to four tunable voices, can be used as the basis of the resonators’ frequencies. Alternatively, these pitches can be derived from incoming MIDI notes, making it possible to play BLEASS Spectral Resonator as though it were a synth, with up-to eight voice polyphony, glide and pitch-bend. The plugin then generates up-to 256 harmonics/partials from each of those base resonators, with each harmonic contributing its own overtone resonances to the overall effect.

BLEASS Spectral Resonator enables deep control over the sounds being produced, and does so via a user interface that’s as easy to master as it is beautiful to behold. The principal resonator settings are governed by intuitive rotary controls, while the gorgeous spectrum analysis display doubles-up as a dynamic means of controlling the integrated filter. This filter operates in the spectral domain and lets you select the frequency band sent to the resonator.

Beyond MIDI control, 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.

BLEASS Spectral Resonator opens up entirely new possibilities for harmonic, rhythmic, and dynamic sound design, even with inharmonic or atonal sources such as drums.

Looks interesting - pity about the awful demo

Here's another demo:

Hmm, have to see how this compares to nudist’s fermenter, which I just bought the other day.

I guess fermenter does not really do vocoding.

There are a handful of presets which really impressed me.
Probably too expensive to buy just for those, so would need to demo it and wait for a decent sale if they do those.

They need to make demo strictly with vocoder sounds.

I'm curious how it compares to Ableton Live's spectral resonator. Maybe this weekend I can demo it.

I forgot that GsDPS's Magic plugins also exist.

Is this like Bismuth that came out a couple of months ago - https://lunacy.audio/products/bismuth/

Any demos as a vocoder?

idk if it's similar. i can't take a plug in seriously if it has animated crystals in the center of the gui so didn't look beyond that.

Then you are missing out, which is fine if you dont mine missing out because you dont like crystals in your UI lol

yeah.. i'm fine w/it. also, have too many plug ins to explore as is. i don't want to own everything for the sake of owning it.

someone is always saying "you're missing out" about some plug in.. who cares.. i don't

What kind of latency does this thing have? Is it ok for real time processing?

Tried it, does not disappoint, many interesting sounds + midi tracking can keep it musical.
