A VHDL-implementation of my
model is used to add saturation effects to audio signals
in real time making it possible to emulate magnetic tapes and
side effects of coils and transformers in analog audio signal paths.
The model runs with surprisingly low resource usage and has
full coverage of the typical effects though. It shows a
deviation of less than 5% from the measured behavior of
classical ferromagnetic materials.
