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

Abstract

The invention relates to a sound box control technology, in particular to a method for debugging a speaker system. The method comprises a step of establishing a speaker system model, a step of modifying virtual input processing parameters and a step of modifying virtual output processing parameters, wherein the speaker system model comprises a plurality of sound box models; each sound box model corresponds to one entity speaker and comprises the virtual input processing parameters and the virtual output processing parameters; the virtual input processing parameters comprise one or a plurality of pieces of virtual DSP (Digital Signal Processor) data; and each piece of DSP data comprises a plurality of layers of DSP parameters which belong to the same type. Therefore, no matter how many layers of DSP parameters each entity DSP data of each active speaker comprises, the multilayer adjustment of the input processing parameters of system layers can be implemented by the technology, so that the debugging and correcting operation of the speaker system is simplified, the debugging efficiency is improved and the debugging effect of the system is ensured.

Description

technical field [0001] The invention relates to a speaker control technology, in particular to a method for debugging a speaker system. 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 refinemen...
