The main functions of the equalizer include:
Adjust the spectrum balance: the equalizer can adjust the volume of audio signals in different frequency bands, so that bass, midrange and treble are more balanced in the whole spectrum. By increasing or decreasing the volume in a specific frequency range, the clarity and timbre of audio can be improved.
Correct audio defects: the equalizer can adjust the volume of frequency range according to the characteristics of audio signals to correct audio defects. For example, by increasing the volume of the treble frequency range, the brightness and details of the audio can be improved; By increasing the volume of bass frequency range, the bass effect of audio can be increased.
Eliminating feedback problem: In live audio application, equalizer can be used to eliminate feedback problem in audio system. By reducing the volume of the feedback frequency range, the feedback sound can be reduced or eliminated, and the stability and reliability of the audio system can be improved.
Adjust audio effects: Equalizers can be used to adjust special effects of audio, such as adding bass effects and emphasizing vocals. By adjusting the volume of different frequency ranges, you can customize and adjust various audio effects.
In a word, the equalizer can balance and equalize the audio signal by adjusting the volume or gain of different frequency ranges in the audio signal. It plays an important role in audio processing and audio system, which can improve the clarity, timbre and effect of audio, and improve the performance and sound quality of audio system.
