Funicular

Funicular transforms Playdate into a portable real-time audio effects processor.

Connect an external audio source using a standard CTIA headset splitter, then build a chain of three DSP effects to create everything from tape wobble and vinyl coloration to delay, fuzz, filters and bit crushing.

The DSP engine is written entirely in C and processes live audio with low latency. Effects can be freely reordered, presets can be saved and recalled, and the crank provides an intuitive way to adjust parameters.
