How to choose entertainment audio according to the sound quality of the audio?

　　, The stage performance of the sound field

　　The spatial sense of the sound field is closely related to the placement of the speaker: the three-dimensional height, width, and depth of the sound field extend to the wall. This height, width, and depth will form a convex and concave shape or a relatively flat, square, rectangular, or elliptical shape. , That is, the overall sound field shape that extends up, down, left, and right, front and back. This shape of the sound field is the space of various shapes. The best space of the titanium sound film is to fill the entire listening room, and it is easy and transparent. The sound field has a sense of space, and even has the performance of penetrating the surrounding walls. Basically, in addition to good entertainment audio equipment, there must be an appropriate space size. It is difficult to achieve a perfect sense of space in a small space.

　　The level and sense of positioning of the musical instruments and vocals in the sound field. The level refers to the three-dimensionality of the musical instruments and other sounding bodies in the sound field and the changes in depth or distance. The sense of localization refers to the three-dimensionality of the sound field of the sound field. s position. The level and sense of positioning are good, and various musical instruments and human voices have a three-dimensional body feeling. If the entertainment audio system equipment is not good enough or the speakers are not well placed, the body feeling will not be heard, especially if there is a deep level of body feeling. The overall sound field should be formed on the stage behind the left and right speakers. If the sound rushes forward, it is not right, especially when the low frequency performance is rushed forward, it feels like a heavy blow to the chest. For a while, I thought it was a high volume force that feels enjoyable, but it will be fun to listen to it for a long time. Very uncomfortable, it is incorrect performance.

　　2. The density and weight of sound

　　The density and weight of the sound in the overall shape of the sound field are related to the amount of sound details and the stability of the sound field. The sound field has high stability and strong weight. It is also the performance of the accurate positioning of the instrument and the appearance of the body. . The high density of the sound is the performance of more details and full sense of sound. The higher the density, the better the enveloping or hug feeling of the ears or the body, and it will feel like being on the spot.

　　Three, the transparency and clarity of the sound

　　The transparency of the sound field is related to the sound itself and the cleanness of the background, and in terms of instrumentation, it is related to the contrast of S+N/N. Good transparency, good sense of space, clarity must be good, sound mixing, sound paste such as interlayer fog or hazy yarn, the sound field must be relatively flat and no depth, the sound image is larger or even a ball, the common bass hypertrophy of the titanium sound film This is just one example, or the bass is lumped into a ball. Some people think that the bass is strong and powerful and they are happy. This is actually wrong. You can compare it to a live music concert.　　 Clarity is often confused with the phenomenon that the mid-to-high volume feels more and brighter. The mid-to-treble tone is brighter and more frequent, and the overall low-frequency ratio is reduced. The low-frequency clarity is difficult to do well, and it can be determined from the degree of discrimination of the bass drum's end rhyme or the slight vibration of the Double Bass string.

　　Four, the balance of high, middle and low frequency bands

　　The high, medium, and low frequency bands of the sound are balanced to be pleasant. Too bright (too much high frequency), especially lip-tooth sounds, is uncomfortable, too dark (too little high frequency) is not vivid, and low frequency expansion (too much) will overwhelm the subject , And the lack of low frequency will be like the lack of something in the bottom plate, lack of integrity, or the midrange is too strong and not thick enough, it lacks the warm and rich sweetness, and becomes dry.

　　Five, the beauty of sound quality

　　requirements are not only smooth, the music can also infect all emotional communication, or the softness or surging heroic feelings like a spring breeze, poetry and painting, and the sound quality is not beautiful, it produces the feeling of raw, cold, hard, thin, and thin.
