Quantizing refers to the process of dividing a continuous signal into a discrete signal, typically in digital signal processing. It is an important aspect of digital audio production. A few synonyms for this term are sampling, digitization, discretization, rounding off, and quantification. Sampling is the process of extracting a portion of the signal at specific intervals. Digitization is the process of converting analog signals into digital ones. Discretization is converting continuous signals into a sequence of discrete values. Rounding off involves approximating numerical values to the nearest digit. Quantification is the process of assigning numerical values to physical quantities. Using these synonyms can help to add variety to your writing and improve clarity in your communication.
