This article mainly introduces what the sound signal in the computer refers to, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, let the editor take you to understand it.

The process of digitizing sound signal includes sampling, quantization and coding. Sound signal is a kind of analog signal, and if the computer wants to process it, it must be converted into digital sound signal, that is, digitization.

Sound signal is a kind of analog signal, and if the computer wants to process it, it must be converted into digital sound signal, that is, digitization. The process of audio signal digitization is generally divided into three steps: sampling, quantization and coding.

Take a sample. Sampling is to convert a continuous analog signal into a signal with discrete time and continuous amplitude.

Quantification. Quantization is to convert each sample of continuous values (analog quantities) in amplitude into discrete values (digital quantities).

Code. In order to facilitate the storage, processing and transmission of the computer, it is necessary to compress and encode the sampled and quantized sound signals according to certain requirements.

Thank you for reading this article carefully. I hope the article "what is the sound signal in the computer" shared by the editor will be helpful to everyone? at the same time, I also hope that you will support and pay attention to the industry information channel. more related knowledge is waiting for you to learn!
