BLEASS Spectral Reverb is an effect and sound design tool that gives you precise control over how ambience evolves across the frequency spectrum. Its intuitive Spectral Maps let you shape different frequency regions independently, creating anything from smooth, expansive spaces to fragmented and glitchy textures. Attack, Decay and Width each come with their own frequency-dependent Spectral Map, extending the core reverb far beyond conventional controls. Freeze and Kill bring instant control over evolving tails, while Block Size, Hop Factor and Smooth Size let the spectral engine move from clean and precise to rough, fragmented and characterful. Four processing slots can host any of six dedicated spectral effects: Spectral Gate, Harmony Follow, Spectral Ducker, Spectral Enhancer, Pitch Shifter and Frequency Shifter. Shape, enhance, duck or shift selected parts of the spectrum, with external sidechain support for even more responsive processing. Explore spacious, polished, abrupt, fragmented and harmonic reverbs with the depth and immediacy of BLEASS Spectral Reverb. BLEASS Spectral Reverb is available as an AUv3 plugin or a standalone app. BLEASS Spectral Reverb is also available on Windows, macOS, and Linux.
