ArdenButterfield/delay-lines ? reverse-engineered prompt

Build me a desktop audio plugin called EchoLocation Delay Lines.

I want it to feel like a visual delay web where each delay line can be dragged and stretched like a spider web, and changing the length of a line changes the sound in a musical way. When I make a delay line longer it should drop in pitch, and when I shorten it it should rise. The main experience should be playful and interactive, with a clear visual editor for shaping echoes, reverbs, filters, and resonant spaces by moving the lines around.

Please make it work as a real audio effect plugin with a polished interface, sensible defaults, and responsive controls. If there are demo sounds or example states that help show it off, include them. Use the existing project docs if they help, and look up current JUCE or plugin build docs online if you need to.
