Introduction to basic frequency-domain components of various sounds

1. drum (size) Kick drum):

the drum is one of the most important parts of a song because it pushes the rhythm forward. Here we will discuss how to deal with the three common types of drums: the first one is called the "1980s drum". You must be familiar with the following: strong and powerful, rich in intermediate frequency, and a "bang" sound containing heavy hits, to get this nostalgic drum sound, you can first filter out the frequency below 60Hz, and then increase it to 3 to 6 dB (size) with a Q value of about 1 at Hz according to the situation ), it sounds like hitting your chest. Next, we will increase the bandwidth by about 6 dB in 1.5-1.5 kHz to increase the "bang" sound (size) q value in 2.5-), and then decrease the bandwidth by about 4 dB (size) At Hz) q: 1.0 ). The second type is the most popular Bonham rock drum. I usually get this sound at-Hz and increase it by 4 dB or more. I also need to filter out all frequencies above kHz, sometimes there may be another type of drum that is commonly used now: it is relatively empty and has a friction sound. If you want this sound, you can filter out all the sounds below Hz and increase them around Hz, increase by about 4 dB at-Hz. Filter out all frequencies above 2 kHz.

2. military drum:

currently, there are two types of most widely used military drums: compact and powerful, another loose and relatively long (size) is usually used for Ballads-style songs) First, any military drum does not require sound below Hz, so it is filtered out. The center frequency of the Military drum is usually within several hundred Hz in the vicinity of 1 kHz. Therefore, it is very beneficial to increase the frequency by 3-6 dB. For the Compact Military drum, you can try to increase the average frequency (near (size) 5 kHz) and some high frequency (size) 8-9 kHz) respectively. The increase can start from Mbps, change the frequency of the upgrade to the desired effect. Filtering out frequencies below Hz and above 11 kHz will make the drums sound quite comfortable. For the loosely-formed military drum, some improvements need to be made at the low end (near the (size) 250hz). I usually upgrade it to 6 dB. High Frequency does not need to be significantly improved like the Compact Military drum, but slight improvement near 7 kHz is usually beneficial, and the upper frequency band can be filtered out. The key is the intermediate frequency. First, move the upgraded frequency between-2 kHz, find the frequency that can resonate, and then adjust the increase amplitude and Q value. For this type of military drum, it is often necessary to add a longer start time (size) Attack Time) compression and heavier reverb to work with it.

3. Round (size) cymbal ):

For these high-frequency drums, the frequency below 4 kHz can be reduced, and the increase in the high-frequency zone (size) is 10-14 kHz) is about 3 dB.

4. shaker, tambourine, conga, and hand clap:

shaker and tambourine are similar, to be bright and run through the high-frequency zone, I usually filter out all frequencies below 2 kHz to slightly increase the high frequency, for example, 6 dB increase at 9 kHz; the hand bell should be slightly bit When the sound is received, I will filter out the frequencies below 1.5Hz, increase 4 dB at or 2 kHz, and slightly increase at 7 kHz. For the tambourine (size) conga, I usually use a scanning method to find the resonant frequency point and slightly increase or decrease it based on the situation. It should be noted that it is not possible to increase too much, especially when the resonance frequency is low, it may interfere with the drum and bass. To highlight the impact of conga, I usually perform a slight improvement in the intermediate frequency (near (size) 5 kHz), for example, 6 dB improvement. The clap sound can be thick by raising the medium and low frequencies. Generally, it increases by 2 dB (size) by 1.5 at Hz ). To enhance the impact, the medium frequency (size) can be increased by about 4 dB near kHz) and the high frequency (size) can be increased by 2-around 8 kHz ).

5. Piano:

If the piano is the main instrument and only forms music with the voice of a person or a few companion instruments, you do not have to make too many adjustments. If there is no bass, I usually slightly increase the low frequency (size) in addition, it can be slightly increased in the high-frequency zone (near size) 8.5khz), such. If the piano is very plump with other 7-8 instruments, You need to perform some attenuation balancing processing on the piano. Since the piano playing is mostly concentrated in the central audio area, you may need to slightly degrade in the intermediate frequency area (size) 3 or 4 kHz) to make it sound less "honky". Filter out frequencies below Hz, because these frequencies will undoubtedly interfere with the background drum and bass. A slight improvement near 8 kHz can make the tweeter sound brighter. In addition, try to make the transition from the intermediate frequency to the high frequency more natural.

6. embes:

There are many different types of embs and different processing methods. My favorite is this bass: plump, thick, and every note is outstanding. I usually do this with BBS: filter out all the frequencies below Hz, reduce the frequencies above Hz, and increase the tonality by 6 dB at Hz, increase the noise of the dial by Hz to increase the noise of the chord, and then combine the appropriate pressure limiting effect to produce this bass sound suitable for multiple music styles. For slaps and punches, the processing method is basically the same, but there are two differences: do not start to reduce the high frequency from Hz, in the intermediate frequency (size) 4-6 dB (near 2 kHz) to highlight the slap sound. The low frequency filtering point can be set at 50Hz to keep enough rumbling sound.

7. electric guitar:

same as piano, the processing method is determined based on the effect of the entire work. If there is only one rail electric guitar plus drums and bits, it can make the electric guitar sound loud; if there are several rail electric guitar, there are also piano, electric piano, blow and other instruments, therefore, an electric guitar must occupy a reasonable position in the spectrum to be integrated into music. In the first case, as long as there is no conflict with Beth, it can be as loud as possible. When I deal with a small rock band with only one guitar player, it will try to improve the low frequency of the electric guitar, generally, it will increase by Hz or more, and pay attention to the integration with BBS. In addition, according to the sound characteristics of the electric guitar, it can be slightly improved at 700-800hz. If it is needed to highlight the intermediate frequency, it can be upgraded near 3 kHz. If you want to obtain the squashed sound (size) crunchier, you can increase it by about 6 dB in the high-frequency zone (size) by 7 kHz. Similarly, it is a good habit to filter out unwanted low frequencies and high frequencies, but listen carefully to avoid filtering out useful generic and harmonious sounds. For the second large band, assume there are two other electric guitar players. First, filter out frequencies below Hz and above 9 kHz, focusing on the intermediate frequency. You can first use the frequency sweep to determine which frequencies need to be improved and which frequencies need to be reduced. I found that 4 kHz increase and 6 kHz attenuation can achieve good results, but sometimes the opposite is true, mainly depending on the overall requirements of the work. Make sure that the sound of an electric guitar is slightly different when playing at the same time. Otherwise, it sounds harsh.

8. Guitar and string:

For different sound mixing works, the balanced processing of the wooden guitar is significantly different. Filter out all frequencies below 90Hz, and make a slight improvement at Hz. Significant improvements in the intermediate frequency and high frequency: 10 dB was upgraded at 2 kHz and 9 dB was upgraded at 7.1khz. After processing, the wood guitar sounds brighter than other instruments. The balanced handling of strings is very similar to that of a wooden guitar. In many music instruments, I usually filter out most of the low frequencies, and then increase the average frequency (size) to 7 kHz by about 4 dB, in the end, we may use a slope curve to increase air sensation in the high-frequency zone (size) at 10 kHz.

9. Copper Tube and woodwind instrument:

Generally, the intermediate frequency is very prominent, and it is very important to handle the intermediate frequency well. For instruments such as the trumpet, the low frequency filtering points can be set at Hz or higher. when processing the intermediate frequency, avoid turbidity. For the brass instrument with a strong bass, the opposite is true. The high-frequency part needs to be filtered out. For example, if the part above 9 kHz is filtered out, the medium-low frequency should be improved, for example, around kHz. Remember to filter out the frequency bands below 40Hz to avoid low-frequency noise caused by certain speakers. Most woodwind instruments need to highlight the airflow sound, which can be achieved by increasing the frequency band above 9 kHz. The banma pipe can play very low notes, so do not filter out its low frequency. However, for most woodwind instruments, filtering out low frequencies is helpful.

10. lead singer:

11. Background voice:

There are two types of background Voices: one is standard high-octal chorus, I usually use the same balanced setting as the lead singer, and the other is three to four background voices with different voices, the audio and video range spans the entire sound field. In this case, I will use different balanced settings to make them sound spacious and unconventional: for High-sound voices, I usually filter out frequencies below Hz, for low-definition audios, filter out frequencies below Hz and minimize the intermediate frequency (size) (1-4 kHz) without losing the definition of chorus ). In the middle and high frequencies, I made great improvements until I heard the voice of an angel.
