The sound signal is an analog signal. In order for the computer to process it, it must be converted into a digital sound signal, that is, digitized. The process of digitizing sound signals is generally divided into three steps: sampling, quantization and encoding.

sampling. Sampling is to convert a time-continuous analog signal into a time-discrete, continuous-amplitude signal.

Quantification. Quantization is the conversion of each sample with a continuous value (analog quantity) in amplitude into a discrete value (digital quantity).

coding. In order to facilitate computer storage, processing and transmission, the sampled and quantized sound signals must be compressed and encoded according to certain requirements.
