Embodiment 1

[0036] An embodiment of the present invention provides a method for adjusting an audio equalizer, see figure 1 , the method includes:

[0037] 101: Obtain the original gain parameter and gain adjustment parameter of each frequency band of the audio equalizer. Among them, the original gain parameter of each frequency band indicates the corresponding gain value of each frequency band before the user adjusts the audio equalizer; the gain adjustment parameter of each frequency band indicates the value of each frequency band when the user adjusts the audio equalizer. The gain value set by gain.

[0038] 102: Obtain an inverse gain adjustment parameter of each frequency band of the audio equalizer according to the original gain parameter and the gain adjustment parameter of each frequency band of the audio equalizer. Wherein, the inverse gain adjustment parameter of each frequency band is used to eliminate the volume change caused when the gain of each frequency band of the audio ...

Embodiment 2

[0049] An embodiment of the present invention provides a method for adjusting an audio equalizer, see figure 2 , the method includes:

[0050] 201: Obtain the original gain parameter and gain adjustment parameter of each frequency band of the audio equalizer.

[0051] Wherein, the original gain parameter of each frequency band of the audio equalizer indicates the corresponding gain value of each frequency band before the user adjusts the audio equalizer. Specifically, after receiving the user's instruction to adjust the audio equalizer, read the current gain value of each frequency band of the audio equalizer to obtain the original gain parameters of each frequency band of the audio equalizer.

[0052] Wherein, the gain adjustment parameter of each frequency band of the audio equalizer indicates the gain value set for the gain of each frequency band when the user adjusts the audio equalizer. Specifically, after receiving the user's instruction to adjust the audio equalizer,...

Embodiment 3

[0074] see image 3 , an embodiment of the present invention provides a device for adjusting an audio equalizer, the device comprising:

[0075] The obtaining module 301 is used to obtain the original gain parameter and gain adjustment parameter of each frequency band of the audio equalizer; wherein, the original gain parameter of each frequency band represents the corresponding gain value of each frequency band before the user adjusts the audio equalizer; The gain adjustment parameter of each frequency band indicates the gain value set for the gain of each frequency band when the user adjusts the audio equalizer;

[0076] The processing module 302 is used to obtain the inverse gain adjustment parameters of each frequency band of the audio equalizer according to the original gain parameters and gain adjustment parameters of each frequency band of the audio equalizer acquired by the acquisition module 301; wherein, the inverse gain of each frequency band Adjustment parameters ar...

Abstract

The invention discloses a method and a device for adjusting an audio equalizer, and belongs to the technical field of communication. The method comprises that: an original gain parameter and a gain adjusting parameter of each frequency range of the audio equalizer are acquired; an anti-phase gain adjusting parameter of each frequency range of the audio equalizer is obtained according to the original gain parameter and the gain adjusting parameter of each frequency range of the audio equalizer; and gain of each frequency range of the audio equalizer is adjusted respectively according to the gain adjusting parameter and the anti-phase gain adjusting parameter of each frequency range of the audio equalizer. The device comprises an acquisition module, a processing module and an adjusting module. When the gain of each frequency range of the audio equalizer is adjusted according to the gain adjusting parameter and the anti-phase gain adjusting parameter of each frequency range of the audio equalizer, only tone quality is changed without changing volume so that operation is simple, time is saved and safety test can be passed without influencing sound effect.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and device for adjusting an audio equalizer. Background technique [0002] With the development of communication technology, users can not only make calls and send short messages through mobile terminals such as mobile phones, but also play music through mobile terminals such as mobile phones. In order to give users the best sound experience, in the player of mobile terminals such as mobile phones, audio equalizers with various fixed frequency band gain modes (such as classical mode, pop mode, dance music mode, rock mode, etc., fixed frequency band gain modes are provided) The gain value of each frequency band of the mode audio equalizer is a preset fixed value, which cannot be adjusted by the user), and even provides a custom mode audio equalizer with a frequency band of -15dB~+15dB. The user can set the audio equalizer to one of the modes according to actual nee...
