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 gua

Example Embodiment

[0040] Example 1

[0041] The sound system of the method for calibrating professional sound systems for stage and film and television in this embodiment includes a plurality of active speakers, the sound system is provided with one or more array groups, and each array group includes one or more active speakers. This embodiment employs an active speaker as described below.

[0042] like figure 1 As shown, the active sound box includes a signal input unit 11 , a digital signal processor 12 , a power amplifier unit 13 and a speaker unit 14 . The signal input unit 11 is used to receive the audio signal input from the outside of the speaker, and transmit it to the digital signal processor 12 . like figure 2 As shown, the digital signal processor 12 is provided with an input processing module 121, and the input processing module 121 stores a set of input processing parameters, and the set of input processing parameters includes a plurality of physical DSP data. The type of th...

Example Embodiment

[0098] Embodiment 2

[0099] The difference between this embodiment and the first embodiment is that in the step S43: if the physical DSP data corresponding to the virtual DSP data includes the speaker layer DSP parameters and the array layer DSP parameters, then according to the modified virtual DSP data, the corresponding The microprocessor of the active speaker sends out a control signal for modifying the corresponding entity DSP data, and the microprocessor modifies the corresponding DSP parameters in the corresponding entity DSP data according to the DSP parameters in the virtual DSP data contained in the control signal;

[0100]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...

Abstract

The invention relates to a sound box control technology, in particular to a method for correcting a stage and video professional sound system. According to the method, the multilayer adjustable problem of system layers is solved by adopting active speakers with array layer DSP (Digital Signal Processor) parameters and introducing sound box models to virtualize a plurality of layers of DSP parameters; and an array group model is also introduced to implement the synchronization adjustment on each sound box model of an array group. All in all, according to the technology, not only can the difficulty in debugging and correcting the sound system be simplified and the workload is reduced, but also the system debugging can be ensured to obtain a better sound effect.

Description

technical field [0001] The invention relates to a sound box control technology, in particular to a calibration method for a stage, film and television professional audio 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...
