Android phone guitar tuning is not accurate?
You should be able to adjust it accurately. The same guitar tuning app has Android version and ios version, and the functions are the same. As long as the guitar itself has no quality problems or the guitar strings are very low-end, it can be tuned accurately with the mobile app. Sometimes there may be a little error, and manual correction is also possible. It is best to use a professional tuner or a tuning effect device for tuning.
How to adjust the 12 segment of Android large-screen navigation equalizer?
The adjustment method of Android large screen 12 segment eq equalizer is as follows:
The trick of EQ adjustment is to "reduce more and add more", keep the original value of the frequency band you want to highlight, and then turn down the volume of the frequency band you want to weaken.
Second, if you want to highlight the male voice (middle and low frequency), leave 0 at 120Hz and 500Hz, 60Hz and 80Hz can be set to -2 or -3, and the rest are set to-1; If you want to highlight female voice (medium and high frequency), leave 0 for 500Hz and 1kHz, set-120Hz and 1.5kHz, and set-1 for the rest.
How to adjust the equalizer in Android big screen navigation player?
The method of adjusting timbre by equalizer;
1, adjustment of low frequency band, adjustment of pitch, fullness and firmness of various sound sources.
Generally, the frequency range of 20Hz-3 15Hz is divided into low frequency bands, and this adjustment focuses on the main pitch of various sound sources, just like a pyramid. Without the basic part, there would be no steeple part, so the adjustment of bass frequency is very important.
2. Adjustment of intermediate frequency band.
Adjust the second and third overtones, roundness and brightness of each heavy sound source:
Generally speaking, the frequency range from 400 Hz to 2.5 kHz is divided into intermediate frequency bands. As we all know, the tonic pitch of most sound sources will be in the bass part, so their second overtones, third overtones and fourth overtones will be in the middle frequency band; Of course, there are also some sound sources with high frequencies, so the tonic is high in the middle frequency band. In short, the focus of this adjustment is to adjust the second or third overtones of most sound sources and the roundness and brightness of timbre.
3. Adjustment of high frequency band.
Adjust the overtone, color sense and penetration of various sound sources;
Generally, the frequency range of 3. 15kHz-20kHz is divided into high frequency bands. The focus of this adjustment is to pay attention to overtone, color sense and penetration of various sound sources.
4. Adjustment of equalizer in most comprehensive sound systems.

Supplementary explanation:
Mixer, also known as mixer, is used to amplify, mix, distribute, modify and process the sound quality of multiple input signals. It is an important equipment for playing and recording programs in modern radio broadcasting, stage amplification, audio program production and other systems. Mixers can be divided into analog mixers and digital mixers according to the way signals come out.
There are differences in the number of input channels, the number of panel function keys and the output instructions of Mixer. In fact, to master the use of the mixer, we should make an overall investigation. Practice makes perfect through practical operation and contact. The mixer is divided into three parts: input part, bus part and output part. The bus part connects the input part and the output part to form the whole mixer.
Find it useful. I like it.
How to adjust the 36-segment eq equalizer on Android big screen?
Tuning method of 36-segment eq equalizer on Android large screen:
1) Put the measuring microphone in the center of the hall, and put the selector switch on the spectrometer in the OCT file (this file is an octave filter file, corresponding to the characteristics of pink noise). At this time, the LED display on the real-time spectrometer is the frequency characteristic curve of the listening environment. The flatter, the better the frequency characteristics of the club structure sound.
(2) Input pink noise into the mixer, and adjust the mixer to the standard output level, usually OVU, and the output level is +4dB. It should be noted that at this time, the equalizer EQ on the mixer is set to a flat line, that is, all of them are set to zero, which will not increase or decrease the frequency of each segment of the test signal. The frequency adjustment potentiometer at each point of the club equalizer is also temporarily set to zero. Slowly increase the power amplifier volume regulator to hear the pink signal sound, and monitor it with a sound pressure meter until the sound pressure level of the powder noise signal in the hall reaches about 85dB.
(3) Pink noise, as the input test signal of the system, is obtained from white noise through -6dB/oct filter. Compared with white noise, pink noise has higher low-frequency energy. Because the energy distribution of pink noise is close to the real music signal, it is often used as a test signal for audio engineering and audio equipment. The power capacity of general speakers also uses pink noise. Generally, the frequency response of CD players above midrange can be 20 Hz-20 Hz+0.5 dB, which can meet the test requirements.
(4) Adjust the frequency enhancement/attenuation of each point on the equalizer to make the frequency characteristic curve on the spectrometer a straight line.
