ResDelay merges envelope filtering and stereo delay into a single unit designed to transform any audio input into captivating rhythmic and tonal textures. It excels at producing dynamic filter sweeps that respond to the audio signal, allowing you to add movement and groove to drum patterns, basslines, synth stabs, and arpeggios. The plugin's audio-reactive filtering opens and closes based on the signal level, enabling expressive modulation that can enhance tension and release within your tracks.

The filter section offers extensive control over its behavior, including threshold and decay settings that shape how it reacts to incoming sound. Users can adjust frequency range, resonance, and cutoff steepness to tailor the filter's tonal character, from subtle enhancements to pronounced squelchy effects. This flexibility makes ResDelay suitable for a wide range of sounds, from analogue-style bass to intricate pluck groups, providing a cohesive and polished texture.

ResDelay's stereo delay complements the filtering with independent delay times for left and right channels, including straight, dotted, and triplet timing options. It features stereo and ping-pong modes, alongside feedback and hi/lo cut filters for precise shaping of the delay tail. With 75 presets and comprehensive mix controls, this plugin offers a powerful tool to create rhythmic patterns and evolving soundscapes driven entirely by the source audio.
