Description

technical field [0001] The present invention relates to the field of audio technology, in particular to a frequency response correction method, server, terminal equipment and system. Background technique [0002] Frequency response, referred to as frequency response, refers to the change relationship between the sound pressure and phase of the audio output device and the frequency of the audio signal when the audio output device of the terminal equipment outputs the audio signal; the frequency response reflects the response of the audio output device to different frequencies. The response ability of the audio signal, if the frequency response characteristic is represented by the frequency response curve, the flatter the frequency response curve, the higher the response ability reflected by the frequency response, and the smaller the distortion of the audio output by the audio output device. [0003] Therefore, in order to make the distortion of the audio output by the audio ...

Problems solved by technology

[0005] However, the inventors of the present invention have found that when testing the frequency response correction parameters of the audio output device of the terminal equipment, the test environment in which the terminal equipment is located may not necessarily meet the ideal test environment requirements. The ideal test environment requires such as relatively quiet , an environment without acoustic interference, which makes the currently tested frequency response correction parameters inaccurate, resulting in low accuracy of the frequency response correction results for the output audio signal, and there may still be audio output from the audio output device Possibility of high distortion
