Audio source input is the process of transmitting sound data from the sound source, that is, the sound card, to the power amplifier, headphones, and speakers. It is divided into two types: 1. Digital signal input, that is, the input is data, which is generally transmitted to the front stage; 2. , Analog signal input, that is, the input is processed data, which has become a sound source and can be played.

What is the audio input?
Audio source input is the process in which sound data is transmitted from the audio source (sound card) to the power amplifier, headphones, and speakers.
It is divided into digital signal input (the input is data, usually transmitted to the preamp) and analog signal input (the input is processed data, which has become a sound source and can be played).

The difference between sound source input and microphone
1. Different subjects
1. Sound source input: the sound data is generated by the sound source ( sound card) to the power amplifier, headphones, and speakers.
2. Microphone: It is an energy conversion device that converts sound signals into electrical signals.
2. Different sound processing processes
1. Sound source input: The input is processed data, which has become a sound source and can be played.
2. Microphone: The human voice vibrates the diaphragm through the air, and then the electromagnetic coil winding on the diaphragm and the magnet surrounding the moving coil head form a magnetic field cutting, forming a weak fluctuating current. The current is sent to the amplifier, and the reverse process is used to convert the fluctuating current into sound.
3. Different effects
1. Sound source input: It will not cause sound field scattering and directly reaches the output end.
2. Microphone: The microphone will inevitably cause sound field scattering in the sound field.
