Most masters debug the subwoofer, but only measure the low frequency by the performance of a kick drum (drum). The kick drum is only a part of the bass. It is a unit of the whole set of drums. At the same time, playing is the overall rhythm part, listening to the bottom drum alone, can only be said to be "sound", can not be used to evaluate the advantages and disadvantages of the bass system.
The five drums and three cymbals cover the high, medium and low frequency bands of the audio. Put them in a group, 8 parts are referenced to each other, and the frequency band is too high or too low to be easily exposed, such as: (å’š, times, big, times), the sound of 'å’š' (drum ) When it is obviously louder than several other parts, it is 40~80Hz too high. It is quite accurate to judge the balance of each frequency band by the sense of music, and it is almost uncomfortable. Spectrometer testing is also affected by environmental factors.
The kick drum is only a small part of the bass, which represents the bass portion of the rhythm part in the drum. The accompaniment of electric bass, double bass and piano left hand are all in the low frequency band. These instruments are played by the chord parts, which play a role in the band. In the low frequency range, only they have details, relatively speaking. The drum is a very monotonous instrument. Therefore, evaluate the texture of the bass, mainly listening to the stringed instrument.
The electric bass we often hear, it plays with the kick drum at the same time, commonly known as "bass drums", it feels only the sound of the drum, but the tail sound is very long, this tail sound is from the bass. Most people think that such a bass is not good and the tailing is serious. Find a way to turn off the "tail". Although the drum sound is clean, the chord is incomplete, the sense of hearing is fragmented, and it looks like a limping walk.
According to the survey, more than 70% of the people did not pay attention to listening to this part, a senior musician said: Someone has not recognized the sound of bass in his life. And the subwoofer and the 6-inch mid-range horn just split the bass into two. If the sound wave is brought back in the air again, it will test the technician's appreciation ability. Therefore, the chord sound is read and played in the whole system. Important role. The middle and high-pitched suits have a crossover set by the manufacturer, which is not the same.
Then, the most common problem in car audio is bass, which is the most common low-frequency instrument. So, today I want to focus on bass and interpret chords.
Bass held the whole music scene in the air, just as several people from Tang Yin and his men marched slowly through the clouds, narrating the hardships and bumps of the road. If there was no bass, it would fall down at once, and the music lacked the motivation to move forward. It is like losing the body of the soul, losing direction and no target. Thin and boring. This is an important factor that supports the audience's continued appreciation. That is, we usually say "tolerance"
What kind of chord sound is correct, it is recommended that you listen to full-range speakers or headphones, they are sent out in a unit. First, there is no cut, and second, there is no reflection of the car. Very harmonious and complete. It's easy to find the feeling.
The band's score is roughly divided into 3 sections.
1. Melody: Walk the same line with the human voice. Representative instruments include violin, erhu, flute, keyboard right hand area, guitar SOLO, etc.
2. Accompaniment: Chord part. Play a role in setting off the atmosphere. The representative instrument has the left hand area of ​​the keyboard, cello, double bass, electric bass and so on.
3. Rhythm: There is no fixed pitch, it is as stable as a pendulum, and the speed of the whole band is controlled to keep everyone consistent. Representative instruments include drums, cymbals, cymbals, wooden fish, scorpions, cow bells, bamboo boards, etc.)
Finally, the overall deployment, multi-instrument comparison method. Like the balance, with the midrange as the fulcrum, the bass is on the left and the treble is on the right. To maintain balance, it is natural to hear. Balance between the cello and the violin, the bass and the guitar should be balanced, the bottom drum and the cymbal should be balanced, a drum, two drums, the floor drum should be balanced, the piano left hand and string accompaniment, balance with the right hand melody, male voice and The female voice should be balanced. These instruments are all in pairs in the band, in order to maintain a sense of balance. This is broken down, everything is simplistic, repeated cross-validation debugging, and finally it will be quite perfect. Better than rigid instrument debugging. Don't be afraid, people feel more accurate than instruments.
