What is the difference between mono and stereo 20

Mono can only ** one channel of the song (generally the left channel), and stereo is two-channel, can hear the sound of the left and right channels synthesized, human ears will not be able to distinguish from which direction it comes, so it is called stereo.

The sound quality of stereo sound is better

Mono is a relatively primitive form of sound reproduction, which is to mix audio signals from different directions and record them by recording equipment, and then replay them by a speaker.

Stereo refers to sound with a three-dimensional sense. The sounds produced by nature are stereo sound, but if we record, amplify, etc., and then play back these stereo sounds, all the sound is emitted from one speaker, and this reproduction sound (compared to the original sound source) is not stereotype. At this point, the original sense of space, especially the spatial distribution of sound clusters, is lost because all kinds of sounds are coming from the same speaker.

This replay is claimed to be monophonic. If the entire system from recording to playback can restore the original sense of space to a certain extent (it is impossible to restore it completely), then this kind of reproduction sound with a certain degree of spatial distribution characteristics such as a sense of orientation and hierarchy is called stereo sound in sound technology.

First, the meaning is different.

Mono is the oldest and most basic way of recording sound with only one audio channel. Because mono has only one audio channel, there is no difference in the information received by our brain from the left and right ears, and the auditory system will not produce psychoacoustic localization, so there will be no difference in width and depth.

Stereo is stereo sound, that is, the songs you listen to now are the corresponding headphones, two earbuds, and ** device are two speakers of which audio. Stereo In this sense, everything that is produced by nature is stereo. Such as thunder, trains, gunshots, etc.

Second, the principle is different.

1. Mono.

Mono is the mixing of audio signals from different directions, which are recorded by a recording equipment and then played back by a loudspeaker.

2. Stereo sound.

Stereo sound is derived from the principle of binaural, in which two speakers are placed in space at an angle to each other, and each speaker is provided by a separate channel. The signal from each channel is processed at the time of recording: the principle of processing is to mimic the biology of the human ear when it hears sound in nature.

Third, the sound effects are different.

There are two rings that divide the headphone head into three parts is stereo and binaural. There is only one ring, and the one that divides the earphone head into two parts is mono.

Mono can only be a song with one channel (generally the left channel), and stereo is two-channel, you can hear the combined sound of the left and right channels, and the human ear will not be able to distinguish which direction it is coming from, so it is called stereo When we listen to the sound, we can distinguish which direction the sound is coming from, so as to roughly determine the position of the sound source. The reason why we can tell the direction of sound is because we have two ears. For example, if we have a sound source in front of our right, then because the right ear is closer to the source, the sound travels first to the right ear and then to the left ear, and the right ear hears slightly stronger sound than the left ear.

If the sound source is of high frequency, some of the sound transmitted to the left ear will be reflected back by the human head, so it is not easy for the left ear to hear the sound. This slight difference in the perception of sound between the two ears is transmitted to the nerves of the brain, allowing us to tell whether the sound is coming from the front right. This is commonly referred to as the "binaural effect".

Mono means that two speakers produce the same sound, and binauro means that two speakers will make different sounds, so that stereo sound will be produced.

Mono refers to the process of a sound channel, using a microphone to pick up the sound, and using a speaker to play the sound.

Binaural refers to a channel with two sounds.

Binaural is the principle of stereo sound, two speakers at a certain angle to each other are placed in space, and each speaker is provided by a separate channel. The signal of each channel is processed when recording: the principle of processing is to imitate the biological principle of the human ear when hearing sound in nature, which is basically the difference in phase of the two channel signals in the circuit, so that when standing on the intersection of the axis lines of the two speakers, you can feel the stereo effect when listening to the sound.
