Lese – Sweep (Infinity Filter) 1.4.0 VST3, AU, AAX WIN MAC LINUX
Sweep is where it all began. What started as Max Patch in 2018 eventually evolved into this (and it’s Lese’s first plugin).
Using the same algorithms that sound engineers use to create shepard tones and risset filters, Sweep uses multiple filters to create the sensation of a sound endlessly fading in (or fading out).
In Sweep’s case, the left and right channels can be split and controlled separately for a more complex, stereo sweeping effect.
Intuitive Controls
Instead of manipulating the behavior of filters across the frequency spectrum with a multitude of complex controls, Sweep takes a simple approach: drag the “factor” sliders, like in a graphic equalizer, and the filter bank will follow the curve you create.
Randomness is cool.
Sweep has a built-in random noise generator that can slightly increase or decrease filter values depending on how the noise feels at the moment. Adjust the Phase parameter to customize the action type in each specific case, and increase the Complexity parameter to change the random movement from slow and subtle to fast and complex.
Peculiarities:
Curve-based band amplitude control
Optimized DSP processing system for peak/notch filters (up to 16 bands per channel)
A distribution function that allows the bands to be distributed linearly
Fractal noise based frequency randomization system
Vectorized, resizable interface
Sidechaining:
We’re using sweep as a kind of “pilot program” to introduce a new general-use “Sidechaining” system, where some parameters (where it would make sense) can have their knobs right-clicked on to open up a “Sidechain” menu.
This allows you to have this parameter be modulated by the level of either the main audio input, or the level of an external sidechain signal.
If feedback regarding the sidechain system is positive you can expect to see it added as a feature in lots of our current plugins, as well as a few we’re currently working on
Tempo Sync:
The cascade speed of the sweeping motion can now also be synchronized to the host’s BPM, for situations where some people have requested it.
This synchronization is subtle but can be a great addition in cases where the sweeping motion needs to be accurately reproduced each time in your sound playback.
