Extended data

Digital audio processor is a kind of digital audio signal processing equipment. It first converts multi-channel analog signals into digital signals, and then processes the digital signals with a series of tunable algorithms to meet the application requirements of improving sound quality, matrix mixing, eliminating noise, eliminating echo and eliminating feedback, and then outputs multi-channel analog signals through digital-to-analog conversion.

Definition of audio processing

Audio processing is an audio processing device that we often use when using many large electronic devices. It can help us control music or soundtrack, make it produce different sound effects in different scenes, increase the shock of music or soundtrack, and also control many audio functions on the scene.

Functions of digital audio processor

The internal architecture of digital audio processor usually consists of input part and output part. The functions of the audio processing part are generally as follows: the input part generally includes input gain control, input equalization adjustment, input delay adjustment, input polarity conversion and other functions. The output part generally has several common functions, such as signal input distribution routing, high-pass filter, low-pass filter, equalizer, polarity, gain, delay, limiter starting level and so on.

Types of digital audio processors

1, simple speaker processor

There are simple fixed processing modules, such as parameter equalization, frequency division, delay, frequency mixing and so on. , which is used to connect the mixer to the power amplifier to replace analog peripherals for signal processing.

2. Multifunctional digital audio processor

All input channels have phantom power supply, which can be directly connected to the conference gooseneck microphone. Its internal functions are relatively complete, and some of them have drag-and-drop programming processing modules, which can form a system that users can build freely. Such a processor can generally replace an analog system composed of a small mixer and peripheral devices in a conference system.

3. Digital audio processor with network audio transmission function

Audio data can be transmitted to each other in the local area network, which is convenient for the interconnection of multiple conference rooms. The audio network also supports the control function, and can realize flexible operation of centralized control or decentralized control of the network.

4. Centralized processing of large digital audio matrix.

It is an extremely powerful host. The audio of each room is packaged into network data through the interface box and sent to the processing host in the main control room. After being processed by the host, it is sent to each room through the network for playback.
