Plot Twist
How Splines Quietly Run Your Signal Chain
Splines are flexible, elegant curves used to connect points smoothly. While they’re often associated with animation or design, they have a surprising number of uses in digital audio. From smoothing parameter changes to shaping waveforms, splines are hidden in plain sight making our audio signal processing chains fluid and expressive.
This talk is for anyone curious about what splines are, how they work, and the ways in which they show up in various audio effect processes. We’ll build an intuitive understanding of splines, show how they differ from other interpolation methods, and explore their use cases in everyday audio programming.
Through visual demos and code examples, we’ll connect the mathematical idea of a spline to real-world, audio signal processing scenarios and show how you can start using and optimising them in your own projects.
