DelayCat is such a creative approach to a modern delay plugin, the interface is easy to understand but the capabilities of the plugin are incredibly complex.

Bring new depth and motion to convolution with IRidia, an impulse-response exploration tool that reimagines how reverberation and spatial texture are discovered and shaped. Using AI-driven analysis, IRidia organizes your samples into perceptual clusters based on underlying acoustic characteristics, transforming a static list of files into an intuitive, navigable sonic space.At its core, IRidia features a creative convolution engine built for exploration rather than selection. Instead of choosing a single impulse response, you fluidly move through, and create, clusters of IRs—blending, morphing, and transitioning between spaces to uncover entirely new reverberant textures. From subtle room coloration to vast, evolving atmospheres, IRidia turns convolution into a performable, expressive instrument, opening the door to endlessly interesting spatial possibilities.

What's The Big Idea?

Concatenative Synthesis  

is a method of synthesis for creating new sounds from short pieces, or segments, of audio. This process resembles granular synthesis but offers more control through feature analysis based selection of the grains (segments).

 

DelayCat is a unique tool that combines concatenative synthesis with a delay line. It works by analyzing and breaking down your sound into segments in real-time. Then, it uses these segments to create new delayed sounds, selecting segments with a special algorithm incorporating delay time.

 

With DelayCat, you can make all kinds of effects, from regular delays to completely new textures. It gives you more control over your sound, mixing the best parts of regular delays and concatenative synthesis into a unique blend.

 

DelayCat can also use the analysis data for things like figuring out when a sound starts (onset detection) and intelligent automation of different parts of the delay.

DelayCat was published and presented at the International Conference for Digital Audio Effects (DAFx) in 2023 during the early development of the plugin. The technical research paper is publicly available via the DAFx archive.
