The sound quality of car audio system is different from that of live music performance.
Many audio players are music lovers, and they also use live music to describe how the sound system is characterized. In the car audio, especially for the racing car audio system, there are specific discussions and quality standards for the SQ sound quality. Appreciation of the sound system In addition to appearance and design, most people will agree that the end should listen to the receipt of the goods; and the very emotional sensory identification of the ear identification, how to determine the restoration of the sound system and live music What is the difference between viewing? Today we will talk about the difference here!
Usually we go to the scene to listen to music is not sitting on the stage, but in the crowd. Therefore, what we consider to be “live feeling†refers to the sound heard on the audience seat at a certain distance from the performance stage. The recording of the record is different. Usually, the microphone is placed in the middle of the stage, and the instrument and the singer are very close. This kind of intimate contact is like moving from the distant audience to the center of the band on the stage. The trait of pop-track multi-track recording and mixing.
　　 So, what is the difference between the music that these two different distances and the environment hear? In fact, the answer can be imagined by your own experience. The middle and high notes heard in the auditorium position are softer, the bass is full and the dive is deeper, and the stage space before and after is strong. And when we stand in the middle of the stage and listen to music like a microphone, our feelings are just the same as before. The middle and high notes are not necessarily soft, the teeth are strong, the gasping sound of the throat is close, so the singer’s throat The sound of the silk is particularly clear. You can imagine that the person around you is close to the ear, just like the microphone sings like the singer's mouth. The feeling of the middle and high notes has changed. At this time, it is not enough to be full and moist, feeling the bass or the bass. At the time, the balance and extension of the bass, including the sense of volume, seems to be reduced. Why? In fact, because the bass has a long wavelength, its extension must meet the wavelength requirements for space. Therefore, the bass speed heard in the middle of the stage is fast and the volume is average. From this, we can imagine that some equipment emits the sense of volume and low frequency extension that is not in the recording of the recording, because of the distortion caused by the distortion of the equipment itself. When the cone is still shaking when it should stop shaking, the so-called "quantity" is increased. However, many times we like this kind of "quality" bass. Not only that, but also think that this bass is correct! So, the problem is coming! The debate will naturally happen!
Different "live feelings" difference:
Detailed difference
The details in the recording of the film "The sense of the scene" are much more than the details of the "live feeling" in the audience. Sometimes because of the close recording relationship, some noise and details will affect the presentation and highlight of the main theme of the music. Therefore, the high-resolution recording of a lot of details will make you feel that the music is not very good!
High pitch difference
The high-pitched energy of the recording "live feeling" is stronger than the "live feeling" on the auditorium, and even has a harsh feeling. The sound of the vocals and the sound of the throat are more pronounced and strong in the "live feeling" of the recording. Sometimes, the delicate female voice heard in the audience will be covered by the tooth sound and the throat sound in the recording "live feeling". Unless the microphone is covered with a windscreen, you may not feel the delicate.
Difference in the midrange
The midrange of the recording "live feeling" is thinner than the midrange of the audience "live feeling". On the one hand, due to the high detail of the high-pitched sound, the extremely high-frequency part will be excessively energized, which makes us feel that the mid-range part is thinner.
Speed ​​difference
The speed of the recording "live feeling" far exceeds the "live feeling" in the audience. The closer the distance from the developed sound body, the shorter the sound propagation time and the faster the sound speed. The speed of the sound of the audience's "live feeling" is also significantly slower due to the distance.
Bass difference
The sense of low volume in the recording "live feeling" is significantly less than the sense of low volume in the auditorium "live feeling". This is because the recording of the near-field recording is fast and close. Under the influence of these two fundamental factors, the bass speed is fast and the sense of volume is naturally no more than the long-distance listening.
Difference in atmosphere
The atmosphere of the recording of the recording must be "tight", and listening to the stage at a distance can be easy and calm. If you watch the war from a distance, the general feeling is that the atmosphere is calm. The tense atmosphere that directly participates in the engagement with itself is the feeling that is not seen from a long distance. From this, we can think that when you are in the middle of the band, you will be directly infected by the tension of the musician's concentration.
As the audio equipment that really restores the music information of the record, which one should be the most appropriate or positive reference standard? The answer has already surfaced. Since you are playing an audio recording, you should of course use the "live feeling" of the recording. Guideline.
