Abstract

The invention belongs to the technical field of audio systems, and particularly relates to an audio system balance adjustment method and device. The position of the best balance point of an audio system is calculated according to coordinates of audience positions, and the distances between all voice boxes and the best balance point position are calculated according to the positions of all the voice boxes; the standard distance is calculated according to the distances between all the voice boxes and the best balance point position, and finally according to the distances between all the voice boxes and the best balance point position, the standard distance, volume change rate parameters based on the distances and delay change rate parameters based on the distances, the volume and delay time of all the voice boxes are adjusted. Due to the fact that sound channel balance of the audio system is automatically adjusted according to the positions of audiences and positions of all the voice boxes, the balance adjusting effect is effectively improved, manual adjustment is not needed, and operation is simple.

Description

technical field

[0001] The invention belongs to the technical field of audio systems, and in particular relates to a method and device for adjusting the balance of an audio system. Background technique

[0002] At present, most multi-channel audio systems rely on the user's own hearing skills to judge whether the channels are balanced in terms of channel balance adjustment, and must also be adjusted manually. Obviously, such an adjustment method is time-consuming and laborious, and is limited by the user's own hearing ability. Even many users cannot adjust the channel balance well and cannot obtain the desired sound balance effect.

[0003] In addition, in the use of the sound system, the randomness of the speaker positions of each channel and the randomness of the listener's position will inevitably lead to the listener not receiving the best sound balance effect, which greatly reduces the user experience. If the audience wants to adjust the sound balance effect, each spea...

Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] figure 1 The implementation process of a sound system balance adjustment method provided by the embodiment of the present invention is shown, and the details are as follows:

[0022] Step 101, calculate the best balance point position of the sound system according to the listener's position coordinates.

[0023] In the embodiment of the present invention, the geometric center point of the audience position is first calculated according to the audience position coordinates, and the geometric center point is used as the optimal balance point position of the audio system. The specific calculat...
