Why is it said that the sound from 1 microphone is not stereo 20

Mono is a relatively primitive form of sound reproduction, and early sound cards were more commonly used. When the mono message is played back through the two speakers, we can clearly feel that the sound is transmitted to our ears from the middle of the two speakers. This lack of localizability is naturally backward from today's point of view, but when the sound card was just getting started, it was already a very advanced technology.

Mono lacks positional localization of sound, and stereo technology has revolutionized that. The sound is assigned to two separate channels during recording, resulting in very good sound localization. This technique is particularly useful in appreciation, where the listener can clearly distinguish the direction in which the various instruments are coming from, thus making the instrument more imaginative and closer to the experience.

Stereo technology has been widely used in a large number of sound cards since Sound Blaster Pro, and has become a far-reaching audio standard. To this day, stereo sound is still the technical standard followed by many products.

Stereo is not equal to binaural, the popular introduction should be stereo must be composed of binaural, but binaural is not necessarily stereo, because stereo is recorded according to the principle of binaural effect, if a mono sound source is divided into two channels can not be called stereo, stereo is characterized by the ability to locate the sound left and right. Therefore, if you use a speaker, you will generally not be able to produce a complete audio signal.

The actual sound heard by a person reaches the left and right ears at different times and with different intensity, and people can distinguish the direction of the sound source by judging the difference between them. So only at least two channels can reproduce this effect.

oh。The signal coming in from a microphone is a mono signal.

First of all, stereo sound must be a stereo signal, but binochannel is not necessarily a stereo signal; To collect stereo signals, you must use a professional stereo microphone, and then configure some auxiliary microphones, set the sound image of the auxiliary microphone, and improve the sound field of the signal. In this way, the recorded sound is stereo.

It has to do with people having two ears, just as what two eyes see is three-dimensional, and what you see with one eye closed is different.

Of course, the signal coming in from a microphone is mono.

Even after entering the mixer, the 'stereo' output from the stereo out is already the same mono on the left and right.

What is stereo sound? The effect is as if you were in the environment, which is very realistic, so usually stereo sound is often achieved through multiple speakers!

Do you think it's achievable for a microphone to include multi-directional sounds?!

There will be a slight difference, mainly due to the different mediums.

Normally, the sound we hear is transmitted by air as a medium, and the sound transmitted by the microphone is transmitted through the bones, which is commonly known as "bone conduction".

When two different mediums are transmitted, our own ears will have different auditory effects.

Not quite consistent. The microphone is only a medium to transmit sound, but the quality of the medium will interfere with the transmission quality of the sound, and the sound quality that our ears hear directly is unattainable by many microphones, just like the world seen by the naked eye is still unable to be simulated by many cameras.

The sound is relatively consistent, it is impossible to be absolutely consistent, the acoustic-electric conversion effect of the microphone, and the electro-acoustic conversion effect of the speaker have a great impact on whether the restoration of the sound is consistent.

Normally, the sound we hear is transmitted by air as a medium, and the sound transmitted by the microphone is transmitted through the bones, which is commonly known as "bone conduction".

Sound to yourself, it will be a little different. But others sound consistent.

Hearing one's own voice through the microphone is transmitted to one's ears through air vibrations. And when you hear your own voice, your bones and air travel to your ears, and these two sounds travel in different ways, so they sound a little different.

But when someone hears you from the receiver or in a direct interview with you, it's airborne on the phone, so it won't make much difference.

The microphone is a microphone, there is a difference between ordinary and professional, we hear the sound can not be completely consistent, the sound quality is related to the microphone converter and the quality of each component and technology, so the output sound quality is different, we will hear different effects.

Nowadays, with the rapid development of technology, the more high-performance and well-matched microphones, the closer and closer to the original sound, the more realistic.

There will be some differences.

When recording, there must be a certain amount of sound loss in the recording of the equipment.

There are good and bad microphones, and a good microphone will have a higher degree of restoration.

Therefore, many singers will use their own special microphones for concerts, such as Zhang Jie and Zhang Liangying.

A good microphone will collect your voice very well, and the sound that is reserved is the original sound.

The sound transmitted through the microphone goes through many processes, and each step of the process will affect the final sound result. First of all, the microphone first captures your voice and transmits the sound wave signal to the sound card, which converts the signal into a digital signal, which transmits the digital signal to the speaker, which in turn converts the digital signal into sound waves.

It's not quite the same. I feel that the voice coming out of the microphone is much better than the voice I am talking about.

The sound from the microphone is basically the same as your original voice, but the difference lies in the equipment used, a good device is more similar to your own voice, but the recording from the microphone is different from the sound you hear yourself, the main reason is because you hear bone conduction, and the recorded sound is sound wave conduction.

If the microphone is good enough, it's basically the same. But many people will find that no matter how good the microphone is, the sound they hear is still different. Why?

This is because the sound we hear ourselves talking in our daily life comes through our bones. And the sound in the microphone is coming through the air. One is fixed and the other is gas, and the medium of propagation is different, and the final effect is bound to be poor.

That's why many people think it's nice to listen to their own voices on weekdays, but they're shocked when they hear their own recordings, and that's why.

It's different.

In fact, when the sound is transmitted through the microphone, it may already be distorted. Especially those very common walkie-talkies, as well as **these, when the sound is received by the machine, there is already a part of the energy lost. At this time, the recorded sound is more or less different from the sound we made before.

When we listen to this sound again, we can feel it.

Especially with different machine recordings, this difference will feel more noticeable.

It's inconsistent, how can there be changes.

The sound transmitted through the microphone and the original sound of oneself can not be completely consistent, because the microphone has certain limitations on the response and fidelity of the sound, and you can't 100% record your voice, and the sound heard by others is made by the microphone through the amplifier, and the amplifier will have a certain distortion, so the original sound can not be heard.

Stereo When we listen to sound, we can tell which direction the sound is coming from, so as to roughly determine the location 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 at a high frequency, some of the sound transmitted to the left ear will be reflected back by the head and limb of the person, 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".

If the spatial position of different sound sources can be reflected during recording, people can listen to the recording as if they are directly hearing the sound of various sound sources. The sound reproduced by this sound playback system with a three-dimensional sense is called stereo.
