What are the concepts of digital surround channel and 7 1 channel

The sound channel is based on the sound channel, and the single rear ** channel is divided into two channels, the rear left and the rear right, and the sense of sound orientation from the back is stronger after separation, which brings a more realistic sense of sound field when playing games or appreciating ***. The channel has a two-way rear center, and the biggest function of this two-way rear center is to prevent the listener from hearing the deviation of the sound field because he is not sitting on the emperor's throne. Because the human ear is divided into left and right, if there is only one center speaker behind you, the sound field will be deviated, and this deviation will cause sometimes you feel that the sound is closer to the left, because your left ear receives the sound first, and sometimes you will feel that the sound is on the right, and the sound field will not have a three-dimensional sense, almost a very flat sound, it sounds wrong.

The reason is: when the front of your ears is not directly facing the pronunciation point, you need two horns to correct the phase difference, which is why you need to use at least two horns (stereo) to listen. In a computer speaker system

1 refers to the number of speakers, and the difference between them is in the number of surround speakers: there are 2 surround speakers (left and right surround), 3 surround speakers (left and right surround plus rear channels), and 4 surround speakers (left and right surround plus two rear channels).

Front, center, rear, subwoofer

Channel refers to the use of 4 surround speakers.

The function of the vocal channel is simply to establish a set of sound fields around the listener with a relatively balanced front and rear sound field, surround is actually virtual, in fact, there are only 5 sound zones (left front hidden flame surround, right front surround, center surround, left rear surround, right rear surround). The remaining 2 registers (left and right) are assigned from the main register.

The earphone channel refers to the earphone support channel input, the earphone of the channel is integrated with a speaker in the front, middle and rear of each earcup, and there is also a woofer in each earcup, the sound quality is clear, the sound effect is more prominent, and the general use of Zhaoying in the game gives people a better hearing effect.

Sound problems, the sound is the best.

As soon as I talk about the concept, you will know the difference.

1. First of all, the two channels are the left and right channels, but when the two channels can be adjusted separately (note that they are separate), and the sound can form a sound field with the ** signal, so that you can feel that the sound changes with the environment, one will be left and one will be right, then this is surround two channels.

1 surround sound belongs to 6 channels, it includes 6 channels: center, left front, right front, left rear surround, right rear surround, and subwoofer. But it is generally believed that the subwoofer does not belong to the vocal channel, so the subwoofer is the one in it. And so on, there are, channels, etc.

In the same way, when each channel can be adjusted separately to adjust the sound size, especially when the two back channels and the front channel form a sound field, it is called surround sound. For example, if you are playing a racing game and you overtake from the left, if you hear a sound coming from the center front right first, and then from the rear right channel, then this has a surround effect.

Since the two sets of channels face each other, the sound field in the basic sense is formed, and the Doppler effect can be realized.

and other complex sound effects. Listening to the sound in the vocal tract, you only need to move your position slightly, and you will feel the difference in the distance of the incoming sound.

Surround sound is a category that falls under the category of stereo sound.

In China, stereo sound usually refers to two-channel stereo with two channels, and more than two channels are called surround sound.

One of the key points to distinguish surround sound is that the sound source contains surround channels in addition to the left and right main channels, that is, in addition to the left and right channels in front of the listener, there are also several surround channel speakers placed behind the listener.

Binaural stereo can only reproduce the sound in front of the listener (you can hear the left and right position and distance of the instrument, but you can't hear whether the instrument is in front of the listener or behind), and surround sound can restore the sound from the front and back, such as the footsteps from behind when watching a movie, and the applause from the audience behind the left when listening to a theater recording, etc., there is a feeling of being surrounded by sound.

It's flat sound, it's stereo sound.

It's a square hexagonal, plus a center and bass in front. All sounds are in one plane.

It's four on the head, four on the feet, and one bass. The bird flies from the ground to the sky, and its trajectory can be heard completely, which is the true meaning of sound.

Use it to play games and watch movies, and you will have a real sense of immersion.

It's the same as 8 with 8 independent channels! The difference is that there are seven channels plus a separate subwoofer active speaker! Choose well! The bass part is shocking!
