What does analog audio mean?

Analog audio is the technology that transmits, records, plays back and processes sound signals in an analog state, and it is the most basic and traditional technology that sound systems rely on. Analog audio, also known as analog signaling, refers to the use of electrical signals to mimic the change in physical quantities of sound; sound is a signal that changes continuously in time and amplitude, so analog electrical signals also change continuously in time and amplitude.

Introduction of analog sound quality and timbre

However, there are many drawbacks to the processing of such signals, such as poor immunity to interference, susceptible to mechanical vibration, analog circuits that produce distortion, and long-distance transmission affected by the environment and so on; although it is a signal that can be heard directly by the human ear, the real effect is often difficult to hear.

Therefore, to hear beautiful music, analog signals need to be converted to digital signals, also known as sampling, through a device called an ADC. This is then edited and produced to get great music.

The technique of transmitting, recording, and replaying sound signals in an analog state, plus processing. Analog tone when the sound is picked up and processed by magnetic recording or mechanical scale way to record down, at this time on the magnetic tape on the remaining magnetic changes or dense pattern, the record sound groove of the grain undulation changes are corresponding to the changes in the sound signal, proportional.
