Frequently Asked Questions and Solutions for Professional Audio Tuning

Common audio tuning problems and solutions

1, the microphone is dry, singing tired:

Reason: The IF energy of the microphone is not enough; the solution: increase the 800Hz frequency band;

2, bass hard:

Reason: The upper limit energy of the subwoofer is too strong; the solution: attenuation 125-160Hz;

3, bass dispersion:

Cause: The low frequency lower limit energy is too large; solution: increase the subwoofer lower limit frequency;

4, bass mixing:

Cause: The low frequency center frequency energy is too strong; the solution: attenuation 60-80Hz;

5, the sound is thin, or the sound is dry:

Cause: The medium and low frequency energy is insufficient; the solution: increase 250Hz;

6, the sound hit the ear:

Cause: The intermediate frequency is too strong; solution: attenuation IK-1.25KHz;

7, sound fried:

Cause: The medium and high frequency energy is too strong; the solution: attenuation 2K-4KHz;

8, the sound is harsh:

Cause: The high frequency energy is too strong; the solution: attenuation 6KHz;

9, the voice is irritating:

Cause: The high frequency is not compliant; solution: attenuation 8K-1OKHz;

10, the sound hair:

Cause: The ultra-high frequency energy is too strong; the solution: attenuation 12K-16KHz;

11, feeling high, medium and low frequency disconnect:

Cause: The frequency band near the frequency dividing frequency is excessively attenuated; Solution: Increase the balance near the frequency dividing frequency and increase the degree of convergence;

12, the combination of sensory microphone and accompaniment music is not good:

Reason: 1 The ratio of microphone and music is wrong; 2 The effect of pre-delay parameter is incorrect; Solution: 1 Re-adjust the ratio of microphone to music at 6:

    4; 2 reduce the delay time of the effector;

13. Feel the lack of flexibility in the bass.

Cause: The subwoofer is not coordinated; the solution is to attenuate the frequency close to the lower limit of 40 Hz or 50 Hz, and raise the reference frequency band by 80 Hz;

14. The vocals are not clear enough:

    Reason: The middle and low frequency is too fat; the solution: attenuation 300-500Hz;

15, the voice is not transparent:

Cause: The medium and high frequency is insufficient; the solution: the mixer's intermediate frequency sweep to 3K, appropriate upgrade;

16, the subwoofer is too soft, powerless:

Cause: The crossover point is set too low. Solution: Increase the crossover point to about 120 Hz and increase the 100-125 Hz band.

17, the full-range speaker does not feel transparent:

Reason: The medium and high frequency is missing; solution: increase 3·5KHz;

18, the microphone sound is too hard:

Reason: The ratio of medium and low frequency to medium and high frequency is incorrect; solution: attenuation 500-630Hz, attenuation 1.6K-2.5KHz;

19. After the microphone is added to the reverb, the sound is mixed;

Cause: The low frequency of the reverberation sound is too much; the solution: properly attenuate the low frequency of the reverberation on the mixer;

20, the ultra-low frequency sound pressure is not large, but the resonance sound is strong:

Cause: The ultra-low frequency lower limit energy is too strong; the solution: greatly attenuate the frequency band below 50 Hz;

21, the sound layering is not good:

Cause: The intermediate frequency is too strong; the solution: wide range attenuation 800-1.6KHz;

22. Insufficient high frequency space:

Cause: The high frequency band of the high frequency unit is not good; the solution is to fully attenuate the frequency band below 10K to 2KHz, and then increase the gain as a whole;

23, the system has a pressure limiter, when the pressure limiter starts working, the bass is scattered;

Cause: The start time of the compressor is too fast; the solution: slow down the start time of the compressor;

24. After the microphone is added to the excitation process, the sound is hairy and stinging;

Reason: The excitation amount is too large, and the excitation frequency is too high; the solution: reduce the excitation amount and reduce the excitation frequency;

25, after the music is added to the incentive, the bass is mixed and feels hypertrophy;

Reason: the amount of incentive is too large, the excitation frequency is low; solution: reduce the amount of excitation, increase the frequency of excitation;

26, the microphone sound thin, flat;

Cause: The low frequency is insufficient; the solution: the mixer balance sweep to 300Hz or so, or the equalizer boosts 250~300Hz;

27. After the microphone is added to the reverb effect, the clarity is reduced and the singing is tired;

Reason: The reverb tail is too long. Solution: Use the reverb tail attenuation knob DECAY to speed up the reverberation tail decay time. After the vocal stop, the half beat to 1 beat reverb stops.
