quantisation
Converting to steps
Quantisation is the British spelling of quantization.
In physics, it describes restricting a quantity to discrete values rather than a continuous range—the foundation of quantum mechanics.
In signal processing, quantisation converts continuous analog signals into discrete digital values: The audio quality depends on the quantisation bit depth.
In music production, quantisation snaps notes to a timing grid.
