What is the concept of "sound field"? In the birthplace of fever music, there are two words related to the sound field, one is "Sound Field" and the other is "Sound Stage". "Sound Stage" mainly refers to the position and shape of the band's arrangement on the stage, including length, width, and height. It is the concept of a three -dimensional space. The "sound field" we refer to is actually "Sound Stage" because if " "Sound Stage" is directly translated into "Sound Stage" or "Sound". As for "Sound Field", it is actually corresponding to the "sense of space" we previously introduced. Therefore, when we mention the "shape of the sound field", it actually refers to the shape arranged by the band regenerated by your equipment. Due to the uneven distribution of the frequency response curve and the impact of speaker direction (such as the width of the room is greater than the depth or the depth greater than the width), the sound field broadcast by the audio is actually more or less different from the situation when the original recording is when the original recording is different. Essence Some sound field shapes were originally four or four, and there were no arches. Of course, the different shapes of this sound field stage cannot be in line with the original when recording. There is a question worth noting: during the live performance, the band's arrangement is greater than the depth; but in the recording studio, in order to produce sound effects, the orchestra's arrangement method often changes, usually depth will be extended, especially the percussion instrument Will be farther. This is not the arrangement we see in the concert hall.
