Abstract

The invention discloses an audio equipment sound effect commissioning method and device. The method comprises the steps of detecting the limit value and the standard value of each frequency point in an audio equipment balancer when audio equipment is in each sound effect mode, determining frequency response curves of the audio equipment when the audio equipment is in each sound effect mode according to the limit value and the standard value, determining the target frequency response curve among the frequency response curves of each sound effect mode corresponding to a target audio mode contained in a commissioning instruction, when the commissioning instruction is received, and using the target frequency response curve to adjust the frequency points in the audio equipment balancer. Compared with the prior art, the method effectively prevents failure of sound effect mode switching when the volume of the audio equipment is large and ensures the effectiveness of sound effect adjustment, since the frequency points in an audio equipment balancer are adjusted according to the target frequency response curve corresponding to the target sound effect mode when the sound effect mode is adjusted.

Description

technical field [0001] The invention relates to the technical field of audio debugging, in particular to a method and device for debugging sound effects of audio equipment. Background technique [0002] At present, terminal devices with speaker output, such as televisions and interactive electronic whiteboards, need to adjust each sound effect mode before use, so that the sound effect of each sound effect mode can meet its corresponding application occasion. [0003] The existing debugging method is generally to set the gain value of the equalizer in the user menu according to different application requirements, and obtain the corresponding frequency response curve. The disadvantages of this debugging method are: for different sound effect modes, since the output power increases with the frequency response gain, it may exceed the maximum power of the speaker, it is necessary to use the DRC (Dynamic Range Control, dynamic range control) threshold to limit the output amplitude...
