Abstract

The invention relates to the technical field of sound boxes, in particular to a sound debugging method and device based on an amplitude-frequency response curve; the method comprises the following steps: acquiring an audio signal acquired by a microphone, generating a measurement amplitude-frequency response curve of the audio signal, and then, taking a preset standard amplitude-frequency responsecurve as a reference, debugging the measurement amplitude-frequency response curve according to an amplitude-frequency curve fitting target curve algorithm, obtaining a target amplitude-frequency response curve, obtaining corresponding DSP parameters of the target amplitude-frequency response curve, setting the DSP parameters to a sound box DSP, so as to complete debugging of the sound box in a sound system. Therefore, according to the embodiments of the invention, the sound debugging operation can be simplified, and the debugging efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of audio speakers, in particular to an audio debugging method and device based on an amplitude-frequency response curve. Background technique [0002] The sound field is the space in which sound waves propagate. In the indoor environment, when the user needs to play music through the speaker, the audio signal emitted by the speaker is affected by the sound field during the transmission process, which may easily cause distortion of the audio signal. Therefore, in order to reduce the impact of the sound field on the audio signal, it is necessary The audio signal is processed so that the user can obtain a good listening experience at the listening position. [0003] At present, the conventional debugging method for a sound system composed of speakers is to delay, limit, and Frequency division and other operations to adjust the DSP parameters of the speaker, so that the entire audio system can achieve the best...
