signalfilter | A signal filtering library | Learning library

signalfilter is a HTML library typically used in Tutorial, Learning applications. signalfilter has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

“The 1€ filter (“one Euro filter”) is a simple algorithm to filter noisy signals for high precision and responsiveness. It uses a first order low-pass filter with an adaptive cutoff frequency: at low speeds, a low cutoff stabilizes the signal by reducing jitter, but as speed increases, the cutoff is increased to reduce lag.” [Casiez 2012]. This library provides convenience functions to deal with the most common scenarios: single signal, coordinates (as PVector or individual floats), multiple channels. Look at the examples and the documentation for more information. To learn more about the 1€ Filter algorithm, read the CHI 2012 paper (PDF) by Géry Casiez. You can also try the online demo of the 1€ filter for a comparison with other filters.
