Infinity Filter

Sweep is an effect that filters.

Utilizing the same algorithms that sound designers use to create shephard tones / risset filters, Sweep uses a bunch of filters to make your sound feel like it’s rising (or falling) endlessly.

In Sweep’s case, the left and right channels can be split and controlled separately for a more complex, stereo aware sweeping effect.

Sweep is available as a free to download VST / AU plugin for both Windows and Mac platforms.

Extra Information

  • Curve-based band amplitude control
  • Optimized peak / notch filter array DSP (up to 16 bands per channel)
  • Distribution function, allowing for linear distribution of bands
  • Fractal noise-based frequency randomization system
  • Vectorized, resizable interface

  1. Factor band control. Your filter amplitudes will match the curve generated by these control points.
  2. Factor band toggles. Bands 1 and 3 are shelves, and the middle band mimics the response of a "band pass" filter.
  3. Factor band control parameters. The factor bands are generated with the same kinds of parameters as filters are. (first number box is the center frequency, second is the gain, third is the bandwidth (or Q)).
  4. Cascade speed. Controls the rate at which the filters move upwards or downwards in frequency. When split mode is off, a blue slider will appear inside this one to control the other channel.
  5. Split Toggle. When disabled, the left and right channels can be controlled independently of one another.
  6. Cascade Filters. The number of filters to process inside the cascades. When split mode is off, a smaller blue slider will appear inside this slider to control the other channel.
  7. Filter Q. Controls the bandwidth of the individual filters within the filter cascades. When split mode is off, a smaller blue slider will appear inside this slider to control the other channel.
  8. Random Phase. Adjusts the phase of the randomization system.
  9. Random Complexity. Changes how "complex" the randomization function is. At higher values, you will notice quicker, and more eccentric movements when randomness is turned up.
  10. Randomness. Mixes the randomization function into the standard calculated frequencies of the cascade filters.
  11. Q Bias. Increases or decreases (whichever way it's moved from the center) the bandwidth of the cascade filters as they move through the frequency range. Turning it down increases bandwidth in the higher frequencies, turning it up vice versa.
  12. Logarithmic / Linear Mix. Changes how the cascade filters are distributed. At 0%, filters are spaced evenly according to how we perceive pitches (logarithmically), and at 100%, filters are distributed evenly according to a normal number range (ex. 1000, 2000, 3000, 4000, etc).
  13. Dry / Wet Mix. Changes how much filtering is applied to the output signal.

  • Windows: VST3
  • OSX (Intel / ARM): VST3, AU

Should run fine on any recent operating system.
