What does the process of digitizing sound signals include?

The process of digitizing sound signals includes sampling, quantization and encoding. The sound signal is an analog signal. For the computer to process it, it must be converted into a digital sound signal, that is, digitized.

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.
