This repository includes accompanying code for the DAFx24 paper "Interpolation Filters for Antiderivative Antialiasing". You can access the full text here.
The AA-IIR method with linear and cubic interpolation is applied for simulation of the hard clipping nonlinearity (hard_clipper.m) and the diode clipper circuit (diode_clipper.m).
Included libraries are interpolation for cubic interpolation methods, metrics for signal-to-noise ratio (SNR) and noise-to-mask ratio (NMR) calculation, utils for miscellaneous functions (plotting, signal generation, etc.).
