Problems solved by technology

Originally, the workload of adjusting the speakers one by one is already very large, but now it needs to be repeated many times (the number of times is unknown, the time spent and the workload required are very huge
Especially for non-professionals, audio system debugging and calibration is almost an impossible task
[0006] (2) Even if the system has been adjusted and corrected many times, it still cannot guarantee better acoustic effects
Even if engineers adjust each speaker one by one, since the sound system is a systematic project, each speaker will affect each other, and when the engineer adjusts each speaker, it is difficult to predict how the adjusted speaker will affect other speakers. How the speaker will affect it (or how other speakers will affect this speaker), so it can only be estimated empirically

Embodiment 2

[0136] The difference between this embodiment and Embodiment 1 is that in the step S54:

[0137] If the entity DSP data corresponding to the virtual DSP data includes the speaker layer DSP parameter, the array layer DSP parameter and the system layer DSP parameter, then according to the modified virtual DSP data, the corresponding entity DSP data is sent to the microprocessor corresponding to the active speaker A control signal, the microprocessor modifies the corresponding DSP parameters in the corresponding entity DSP data according to the DSP parameters in the virtual DSP data included in the control signal;

[0138] If the physical DSP data corresponding to the virtual DSP data only contains the DSP parameters of the speaker layer, a new DSP parameter is obtained by superimposing and calculating the DSP parameters of each layer of the virtual DSP data, and then the modification is sent to the microprocessor corresponding to the active speaker Corresponding to the control s...

Abstract

The invention relates to the speaker control technology, in particular to a sound system correction method. The method includes that an active speaker provided with array-layer digital signal processor (DSP) parameters (a speaker, particularly, with more than binary frequency) is utilized, and multi-layer DSP parameters are virtualized by introducing speaker models to solve the systematic multi-layer adjustable problem, and further, an array group model is introduced to achieve the synchronous adjustment of each speaker model of an array group. The technology cannot only reduce the difficulty of speaker system debugging correction and the work amount, but also can obtain excellent system sound effects.

Description

technical field [0001] The invention relates to a sound box control technology, in particular to a sound system calibration method. Background technique [0002] Speakers with built-in digital signal processors (DSP) and power amplifiers (also known as active speakers) can perform operations such as EQ adjustment, delay, limiter, and frequency division on the input audio signal through the digital signal processor, so that the speakers can achieve the best performance. working status. [0003] At present, the conventional adjustment methods for the sound system composed of active speakers are as follows: (1) First adjust the input processing parameters and output processing parameters of the digital signal processor of a single speaker (speakers with frequency division above two), such as EQ, delay, limiter, etc. (2) Test the effect of the sound system, and adjust the digital signal processor parameters of the relevant speakers based on experience and further refinement of...
