Vague binaural time diffusion

AAX/AU/VST3 for Mac + Windows


Vague is a binaural time diffusion processor. In its core, the signal travels through a virtual space comprised of 16 all-pass comb filter stages, with their delay times progressively increasing from start to end. The more stages the signal passes through, the more blurred and smeared it becomes, losing its definition and transient sharpness. But Vague goes much further than this: it offers binaural expansion via alternating, stereo-opposed time offsets in the individual all-pass stages, which adds quite a unique, three-dimensional vibe. Another very special feature is the four output snapshots taken as the signal passes through the virtual space: smoothly crossfading between them not only changes the diffusion density, but also makes the timeline granulated. Moreover, Vague can run multiple independent LFOs to modulate its main parameters, creating a wide variety of rich and charismatic effects: time diffusion and dimensional expansion, blurred unison, granular scrubbing, psychedelic reverberation, and much more.


What if you could take the early reflections part of a digital reverb, and turn it into an undulating, stereo-phasing, diffusing blurring granulating unison alchemic wonder? And what if you could give it an easy-to-grok UI? Sinevibes did just that, and the results are unlike anything else. [...] It’s not a reverb, and it’s not a model of anything else. It’s capable of a broad range of reflective, three-dimensional sounds, from unisons to choruses to longer textures. – Create Digital Music
Now, what is Vague? It smears very fascinating audio sources and gives them a very soft unnatural texture. These can sound like choruses, unison, or granular. But all very bizarre and different as you know the effects. [...] A big release from Sinevibes that once again brings a breath of fresh air to the effects scene. – Synth Anatomy
