What is the difference between digital audio and analog audio?

First, the technical means are different

1. Digital audio: It is a technology that uses digital means to record, store, edit, compress or play sound.

2. Analog audio: the technology of transmitting, recording, replaying and adding processing of sound signals in an analog state.

Second, the characteristics are different

1. Digital audio: it is to first convert the audio file, and then convert these level signals into binary data for saving, and when playing, these data are converted into analog level signals and then sent to the speaker for broadcast.

2. Analog audio: after the sound pickup processing is recorded in the form of magnetic recording or mechanical scale, at this time the change or dense pattern of the residual magnetism on the tape, and the undulating changes in the texture in the record sound slot are corresponding to and proportional to the change of the sound signal.

Third, the advantages and disadvantages are different

1. Digital audio: The price is high, because its requirements are high, so the manufacturing cost will rise sharply.

2. Analog audio: In the process of recording, transmission, processing and amplification, distortion and noise are easy to occur, making it difficult to greatly improve the electroacoustic technical indicators of analog audio software and hardware.
