Hz and 10khz can highlight details and make people sweeter. The increase of 14khz and 20khz may cause the sound to become gorgeous and metallic, but it is also easy to change the noise and become more digital. It is recommended that the 20khz slider should not give gain, and the 14khz slider can gain a slight gain. The appropriate gain of 5khz can improve vocal clarity. Appropriate depression of 1.8khz and 2.5khz can play a role in softening and purifying. Appropriate lifting can play a sharp role, but the two sliders should not be ups and downs. The amplitude of 2 dB is already quite bold. The 220hz and 311hz sliders are slightly warmer to make them look warmer. The specific adjustment needs to be adjusted by the user according to the actual environment and equipment, which is also very meaningful. Instrument adjustment range: â— Stringed instruments: brightness adjustment 6KHz and 12KHz, fullness 170Hz and 310Hz, plucking sound 1KHz and 1KHz â— Piano: bass 60Hz and 170Hz, presence 3K and 6K, attenuation 12KHz 14KHz 16KHz sound thin and vice versa. â— Bass drum: 3K percussion, 60Hz bass. â—Drum/tweeter drum/tambourine: fullness 170Hz and 310Hz crispness/presence 6K â—é’¹: sharp sense 6K and 12K. â— Accordion / Organ: Fullness 310Hz, Presence 6K â— BASS: 1K plucking sound, 60Hz bass effect, chord noise (squeaking string) 3K â— Electric guitar: fullness 170Hz and 310Hz, brightness 3K â— Muji: Piano body sound 310Hz, sharpness / macro brightness 3K and 6K, attenuation 12KHz 14KHz 16KHz sound thin and vice versa. â—Small: Fullness 170Hz and 310Hz, crisp 6K some music adjustment methods: 1. When placing string music or symphony, you can increase 60Hz and 170Hz by half, 310Hz, 600Hz to increase quarter by 1K without lifting or a little attenuation, 3K and 6K are properly upgraded, 12K, 14K, 16K can raise 16K to the maximum. The three of them can form a slope of 30 degrees. 2, in the solo or chorus can be slightly increased 170Hz and 1KHz, 3K and 6K slightly attenuated. Frequency description <80Hz Below 80Hz is mainly a low-frequency percussion instrument for replaying music, such as drums, timpani, and a few instruments with very low frequencies such as piano, cello, and large. If this is good, there is no The impact on music appreciation is not great. It is not easy to replay this part, and the requirements for equipment are also high. Many advanced equipment, in order to perform good music in the frequency band above 80 (or 80 or more Hz), would rather cut off the frequency below 80 (or 80 or so) Hz, so as not to affect the playback, but affect the effect of the main frequency band. Extreme low frequency 20Hz is the lower limit of human hearing. It can test the low frequency playback lower limit of your equipment. 25Hz, 31.5Hz, Hz, 40Hz, 50Hz and 63Hz in low frequency are the lower limit of playback of many speakers. If your speaker is in some of these frequencies The sharp drop in sound indicates that this frequency is the lower limit of the low frequency playback of your speakers. 80-160Hz The sound in the 80-160Hz frequency band mainly expresses the thick feeling of music. If the sound is good in this part, the music will feel thick and emboldened. If this part is good, if it is lacking below 80Hz, it will not even feel the lack of bass. If the performance is not good, the concert has a dull feeling, even if it is weak. It is the playback limit of many subwoofer speakers, which can be used to determine the upper limit of your subwoofer speaker frequency. 300-500Hz The sound in the 300-500Hz frequency band is mainly for vocal (singing, recitation). This band can express the thickness and intensity of vocals, but the vocals are bright and clear, otherwise they are thin and turbid. The general equipment of 800Hz 800Hz is easy to broadcast, but be careful not to overdo it. If there is too much, the frequency response of the sound will be narrowed, the treble will be lacking in level, and the low frequency fullness will not be enough. 1000 Hz 1 kHz is the standard reference frequency for audio equipment testing. The parameters usually given in audio equipment are tested at 1 kHz. 1200Hz 1.2kHz can be a little more appropriate, but should not exceed 3dB, can improve the brightness of the sound, but too much will be the sound is hard. 2000-4000Hz 2~4kHz has a great influence on the brightness of the sound, and this sound is generally not suitable for attenuation. This section has a great influence on the level of music. Appropriate improvement can improve the brightness and clarity of the sound, but there is not too much protrusion at 4 kHz, otherwise the female voice will be too heavy. 8000-12000Hz 8~12kHz is the high-pitched area of ​​music, which is most sensitive to the high-frequency performance of audio. Appropriate highlighting (below 5dB) will greatly help the level and color of the sound, and will also make people feel high-pitched. However, too much will increase the background noise. For example, the noise of the system (sound card, sound source) will be clearly expressed, and the sound will be sharp and hairy. If this is lacking, the voice will lack appeal and vitality. 14000Hz above 14kHz is the overtone area of ​​music. If it is lacking, the sound will lack the appeal and noble feeling. For example, the violin will not have "song". This part should not be too much, basically flat or slightly attenuated (not more than -3dB). 20000Hz 20kHz is the upper limit of human hearing, which can test the upper limit of high frequency playback of your equipment. 16kHz-20kHz may disappear in some equipment. At this time, it may be that your equipment cannot replay this frequency. If you are older, it may be due to your hearing loss. The sine wave sweep signal 20Hz-20kHz sine wave sweep signal is automatically smoothed and changed from 20Hz to 20kHz. By playing this test information, you can quickly determine where the frequency has problems. The equalizer adjustment can be divided into the following main segments. : The low frequency of the 20Hz--60Hz part often gives a very loud feeling, such as thunder, which is a powerful and powerful feeling in music. If the elevation is too high, it will be turbid and the clarity will be poor. The 60Hz--250Hz part of this frequency includes the pitch of the pitch and rhythm sounds, and its ratio to the high-pitched tone constitutes the balance characteristic of the tone structure; the strong tone is full, the weak tone is thin, and the strong is the rumble. The 250Hz--2KHz section includes the low frequency overtones and lower harmonics of most instruments. The 2KHz--4kHz part of this frequency is an intermediate frequency. If it is raised too high, it will cover the speech recognition tone, especially if the 3kHz boost is too high, it will cause hearing fatigue. The 4kHz--5KHz section is a field-sensing frequency band that affects the clarity of sounds such as languages ​​and instruments. Raising this frequency band makes people feel that the distance between the sound source and the listener is a little closer; if the attenuation is 5 kHz, the distance of the sound will be farther; if it is raised by 6 dB at around 5 kHz, the sound of the whole mixed sound will be made. The power is increased by 3dB. The 6kHz--16kHz section controls the brightness, macro brightness and sharpness of the tone. The tone and pitch sound of each frequency band is a term used to describe the sound quality of the instrument. Since each instrument has its own spectral distribution characteristics, the pronunciation of the same instrument is in different sound zones, although the sound perception is not necessarily the same. But the tone is roughly the same. The terms that describe the timbre characteristics are generally closely related to the instrument. The timbre term is generally richer than the sound, and the correlation between them is as follows: Dull: This kind of sensation is given by the frequency of about 20 Hz, and when it is higher than 80 Hz, the sound will be thicker, so the sound with dullness is generally low, and there is very little overtone component. The instrument source with this pitch characteristic is generally the bass area of ​​the bass instrument. Heavy: From the perspective of sound sensitivity, the heavy feeling is the unique sound effect at the 80 Hz frequency point, and from the sound pattern characteristics, the short bass sound type musical instrument has a stronger sense of gravity. Low: Low is often used to describe a slightly richer sound. His fundamental frequency may be the same as a dull sound, but most of its higher harmonics are more abundant than dull sound. Deep: This is an emotional adjective, often used to express the color of the "loose" low frequency response, the fundamental frequency is slightly higher than the low sound. Generally with deep sense of the instrument, the most typical is the cello and the bass area. Thickness: This kind of sound is a characteristic of a wide-spectrum sound source, so the thick sound is generally a sound source with a low fundamental frequency and a wide spectrum. Thickness: Thickness refers to the low-frequency sound with high integration, and the typical sound source with a thick sense is the low-range of the celesta. Plump: This is the sound characteristic of the sound source with a frequency between 100 and 250 Hz. Generally speaking, the sound source in this frequency band will inevitably have rich sound effects. Generosity: If the spectrum is wider, a richer sound will be produced. Full: This is a kind of low-frequency sound called strongness. Generally, the electric bass with "turbine distortion" effect is added. This sound characteristic is very obvious. Bright: Generally, when the fundamental frequency of the music is higher than 500 Hz, it will become brighter. Even when it is as high as 7500 Hz, we can't say that it is not bright, so the brightness of the sound source is a relatively general. adjective. The brightness is most noticeable at 2800 Hz. Loud: It is often used to describe a high-definition sound with a neck, and when the spectrum is above 4000 Hz, the sound source does not have this pitch characteristic. Hongliang: A high-bright sound with a certain fusion. Rounded: refers to a softer, high-brightness sound. Soft: Compared with roundness, the softness is more dull and is a relatively low-brightness sound. Crisp: Sounds with a spectrum between 4000 and 8000 Hz generally have a certain crisp effect. Sorghum: refers to the high-penetration crisp sound, and the typical instrument with this phonological feature is 唢å‘. Sharp: The sound of the spectrum concentrated around 6800 Hz is generally sharp and harsh. Sharp and sharp: If you have a sharp sound with a similar distortion, you can produce a sharp sound effect. Slim: Music with a spectrum above 8000 Hz generally has a slender sound effect. Fusion: Soft sounds that are generally difficult to highlight have a certain sense of integration. Of course, all sources can be measured by the degree of fusion or non-fusion. In musical instruments, it is generally believed that the viola and cello have the best sense of fusion. Cognac: This is an antonym of fusion. The high-frequency sounds that are generally lacking in harmonics and dissonant overtones have some degree of cognac. Among the instruments, he is mainly caused by the lack of resonance in the extremely high-pitched area. Solid: A narrow-band sound system of around 600 Hz, and a short-sounding sound pattern, all have a certain sense of sound. Void: refers to a dull sound with a "staining" effect, which is often used to describe the sound of a big wooden fish. Warmth: This is a word that describes the color of the music. He is generally proportional to the "staining degree" of the sound. For example, the clock has a subtle sound. Rough: If the low-frequency sound has an effect similar to overload distortion, it can form a rough sound. Rough: Roughness is a rough sound with a slight sand sound. Generally, the trumpet and the horn have this vocal characteristic when playing the bass zone. Hoarse: Specially made with a false "sound" sound effect. Vigorous: This is an adjective with affection, generally refers to the hoarse sound in the lower frequency band, such as the bass area of ​​the big pipe. Tension: This is the result of some special discordant overtones in the tone. The sense of strength: the sense of strength in the low frequency band specifically refers to the sound in the 200~500 box frequency band, such as: the bass area of ​​Dagu and Dahu, the sense of strength is better. In the middle and high frequency bands, the sense of strength refers to the high-penetration, high-protrusion, soft-sounding sound. In the middle and high-pitched areas of the general high-pitched brass instruments, they have a good sense of strength. Penetration: refers to the high-protrusion, high-brightness sound, the penetration is more obvious around 4500 Hz. Glimmer: refers to a high roundness sound with a certain sense of standing. Sadness: Despair and warmth are anti-sense, and it is also a kind of emotional. The typical instrument sound source with this phonological feature is the midrange of the midrange oboe. Gloomy: High-tension low-range sound can form a gloomy sound effect. Flat: This is the sound effect unique to the 2500 Hz. Music near this frequency point is generally obviously "flat" feeling. Such as: Banhu, Erhu, etc., the second kind of sound characteristics are very obvious. Darkening: If the spectral components above 6000 Hz are missing from the tone, the pronunciation can be made "dark". Deficiency: This is caused by the increase in noise when the instrument is at a higher scale. This noise is usually similar to the airflow. Extremely high frequency: 16K-20K color enhancement has mystery; 12K-16K high frequency overtone, brilliance; 10K-12K high frequency overtone, gloss; high frequency and high frequency low section: 8K-10K S sound; 6K-8K brightness Transparency, enhance the tooth tone, and reduce the sound of the sound; 5K-6K language clarity, improve the sound sharp, easy to fatigue; upper frequency: 4K-5K instrument surface loudness, enhance the instrument distance, the distance of the instrument is far; 4K penetration Force, enhance coughing; 2K-3K is most sensitive to brightness, enhances sound hard, unnatural IF: 1K-2K transparent, smooth, lifting has a sense of jumping, loose loose; 800 strength, increase throat weight; 500 -1K vocal pitch, sound contour, enhance voice lordosis, drop voice contraction; 300-500 voice main sound zone, enhance voice monotony, drop voice hole; medium frequency low section: 150-300 sound strength, male voice strength, enhance sound Hard, no features, landing: soft, floating; low frequency: 100-150 fullness, improve turbidity, drop thin; 60-100 thick feeling, enhance roaring (bang), landing weakness; 20-60 sense of space, enhance low frequency resonance (å—¡), landing emptiness; low frequency upper section 80-160; low frequency 40-80; low frequency lower section 20-40; ultra low frequency 32-~. The effect of sound in each frequency band is that the sound frequency of the human ear is from the lowest 20Hz to the highest 20KHz, while the human speech frequency range is concentrated between 80Hz and 12kHz. The sound of different frequency bands is different for people. 1. The 20Hz--60Hz part of this promotion can give a strong feeling to the music, giving a very loud feeling, such as thunder. If the elevation is too high, it will be turbid, resulting in poor definition, especially for low-frequency response and low-frequency audio equipment. 2. The 60Hz--250Hz part is the low-frequency structure of the music, which contains the basic sound of the rhythm part, including the main sound of the pitch and rhythm sound. Its ratio to the high-pitched tone constitutes the balance of the tone structure. Raising this section will make the sound full, and excessive boost will make a rumble. Attenuating this band and the high midrange will make the sound thin. 3. The 250Hz--4KHz section contains the low-frequency harmonics of most instruments, and affects the clarity of sounds such as vocals and instruments. The adjustment should be in accordance with the settings of the front bass, otherwise the sound quality will become very dull. If the lift is too much, the sound will be like the sound in the phone; if the 600Hz and 1kHz are excessively raised, the sound will be like the sound of the speaker; if the 3KHz is raised too much, the speech of the speech will be masked, that is, the articulation will be unclear and the lip sound will be " m, b, v" are difficult to distinguish; if the 1kHz and 3kHz are excessively raised, the sound will have a metallic feel. Since the human ear is sensitive to this frequency band, this segment is usually not adjusted, and excessively increasing this segment will cause hearing fatigue. 4. 4kHz--5KHz section This is the frequency band that affects the sense of presence (distance). Raising this frequency band makes people feel that the distance between the sound source and the listener is a little closer; the attenuation will make the distance of the sound farther; if it is increased by 6dB around 5KHz, the sound power of the whole mixed sound will be improved. 3dB. 5. The 6 kHz--16 kHz section controls the brightness, macro brightness and sharpness of the tone. Generally, raising this part makes the sound loud, but not clear, and may cause the tooth to be too heavy; attenuating this part makes the sound clear and the sound quality is slightly thin. This band is suitable for reducing vocals. The features of several common EQ combinations are listed below. â— POP: Pop music, which requires both vocal and instrumental music, the combination is average, so the fluctuation of the EQ curve is not very large. â—ROCK: Rock music, its high and low ends are greatly enhanced, the bass makes the music powerful and powerful, the rhythm is strong, and the high-pitched parts are clear and even harsh. â— JAZZ: Jazz, compared with POP, it enhances the 3-5KHz part and enhances the sense of presence. â—ClassICal: Classical music, it is also promoted in two parts, mainly highlighting the performance of the instrument. â— VOCal: vocal, the frequency of the sound emitted by the human voice is relatively narrow, mainly concentrated in the intermediate frequency part. In addition, it should be noted that each person's sound perception of different frequencies is different, and the frequency response of the audio playback device is also different. The human hearing curve is only drawn according to statistical data, so others sound very natural. It may feel uncomfortable, and the adjustment of the equalizer needs to be individually adjusted according to the characteristics of the listening and the playing device used.
