What Is Frequency Domain Analysis?

- Jun 12, 2018-

Frequency domain analysis is an important part of audio analysis. Frequency domain analysis is mainly based on frequency response characteristics. The aforementioned sinusoidal detection, pulse detection, and maximum length sequence signal detection all yield the device's frequency response. The frequency response plot reflects the distribution of the frequency response of the audio device over the entire audio range. In general, the frequency component at the peak of the curve will have a large playback sound pressure and sound pressure; the frequency components at the bottom of the curve will have a low sound pressure and sound. If the wave crests and troughs fluctuate too much, it will cause more serious frequency distortion.
