Nonlinear Filter delivers vintage analog character and dynamic tonal shaping to your audio productions. Inspired by the classic sounds that shaped iconic tracks, this plugin offers a range of filter types including low pass, band pass, high pass, and notch filters. Whether you're aiming to add subtle warmth or dramatic tonal shifts, Nonlinear Filter provides a straightforward approach to filtering with a distinctive analog edge.

The plugin allows you to adjust key parameters such as cutoff frequency and resonance, enabling precise control over how the filter interacts with your sound. With a drive feature that enhances the filter's nonlinear behavior, you can introduce saturation and distortion for more character and presence. Multiple modes offer different flavors of nonlinearity, from clean filtering without coloration to richly distorted textures that add complexity and depth to your audio.

Part of a comprehensive suite of effects known as Snapins, Nonlinear Filter integrates seamlessly with Kilohearts’ modular hosts like Phase Plant, Multipass, and Snap Heap. These lightweight, powerful plugins present essential controls clearly and efficiently, making them ideal for both standalone use and complex routing setups. Available individually or as part of Kilohearts Toolboxes, Nonlinear Filter is designed to enhance your creative workflow and expand your sonic palette.
