Abstract
Disclosed is an audio calibration method that is applied to an audio calibration system. The audio calibration system includes a terminal, a server and an audio playback device, and the method includes: playing, by the terminal, at least one kind of test signal in response to a sound collection command, and performing ambient sound collection to obtain target audio data; uploading, by the terminal, the target audio data to the server, performing, by the server, environmental acoustic parameter recognition on the target audio data to obtain target environmental acoustic parameters; generating, by the server, a calibration parameter of a digital equalizer based on the target environmental acoustic parameters to obtain a target calibration parameter; sending, by the server, the target calibration parameter to the terminal, and transmitting, by the terminal, the received target calibration parameter to the audio playback device.
