Professional speaker system adjustment method

Abstract

The invention relates to the speaker control technology, in particular to a method for adjusting a professional loudspeaker system. The method comprises a loudspeaker system modeling step and a virtual input processing parameter modification step. The loudspeaker system model comprises a plurality of speaker models. Each of the plurality of the speaker models corresponds to an entity active speaker and comprises virtual input processing parameters and virtual output processing parameters. The virtual input processing parameters comprise one or more virtual digital signal processor (DSP) data, and each of the DSP data comprises multiple layers of DSP parameters of a same type. Accordingly, no matter how many layers of DSP parameters each of the entity DSPs of the active speaker comprises, the technology can achieve the multi-layer adjustment of systematic input processing parameters, so that the debugging correction operation of the loudspeaker system is simplified, the debugging efficiency is improved, and the system debugging effect is guaranteed.

Description

technical field [0001] The invention relates to a sound box control technology, in particular to a method for adjusting a professional loudspeaker 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...

AI Technical Summary

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
