The definition and function of audio processors
    Audio processors, also known as digital processors, are mainly used to process digital signals. Its internal structure is usually composed of input and output sections, with rich and diverse functions. Through an audio processor, we can easily control music or background music to present different sound effects in various scenarios, thereby enhancing the impact of the music. In addition, it can also control many audio functions on site, providing a high-quality audio experience for meetings or performances.

Common types of audio processors
    1️⃣ Speaker processor: This type of processor is typically used to connect the mixing console and the power amplifier, replacing analog peripheral devices for signal processing. Common models include the DA series of 2-in-4-out, 2-in-6-out, 2-in-8-out, 4-in-6-out, and 4-in-8-out, etc. They are equipped with simple fixed processing modules inside, such as parametric equalization, crossover, delay, and mixing, etc.
    2️⃣ Multifunctional digital audio processor: This type of processor usually has 8 inputs and 8 outputs or more channels. All input channels are equipped with phantom power and can be directly connected to conference gooseneck microphones. Their functions are more complete. Some even come with drag-and-drop programming processing modules, allowing users to freely build the system as needed. Such processors are often used in conference systems to replace analog systems composed of small mixing consoles and peripheral equipment.
    3️⃣ Digital audio processors with network audio transmission function: This type of processor adds network audio transmission function (such as supporting CobraNet) on the basis of the above functions, enabling the mutual transmission of audio data within a local area network and facilitating the interconnection and communication among multiple meeting rooms. They also support control functions, enabling flexible use of centralized or decentralized control over the network.
    4️⃣ Large-scale centralized processing digital audio matrix: This is a host with extremely powerful processing capabilities. The audio from each room is packaged into network data through interface boxes and sent to the processing host in the main control room. After being processed by the host, it is then sent to each room via the network for playback. Such audio networks are generally based on gigabit Ethernet CobraNet or other protocols, and support real-time transmission and control simultaneously. It is mainly applied in large-scale broadcasting systems or conference centers and other places. Compared with small network audio processors, large processing matrices are centrally placed in a certain computer room. The processing control of all rooms must be completed by the machines in the main computer room. Therefore, no matter whether one or more rooms are used, the processors in the main computer room must be kept on at all times.

Application scenarios of audio processors
    Music production: In music production, audio processors can assist producers in adjusting various parameters of the music, such as volume, sound quality, and sound effects, thereby creating the desired music effect.
    Conference system: In the conference system, the audio processor can ensure that each participant can clearly hear the speaker's voice while reducing the interference of noise and echoes.
    Broadcasting system: In a broadcasting system, the audio processor is responsible for processing various broadcasting signals to ensure that the broadcasting content is conveyed clearly, accurately and promptly to the audience.
    By understanding different types of audio processors and their application scenarios, we can better utilize these devices to enhance the quality of music production and conference systems. Whether they are professionals or ordinary users, mastering the knowledge of audio process

The role of an audio processor
    The audio processor can help users control music or background music, making it produce different sound effects in various occasions, enhancing the impact of the music or background music, and also controlling many audio functions on the spot.
    The audio processor integrates many functions, among which the frequency division function is very important. Frequency division can provide corresponding adjustments based on the different frequency information of the audio equipment in different working states. This function enables the audio processor to adapt to many audio devices. As long as the audio equipment can work normally, the audio processor can accurately process the sound information and convey it to the audio equipment.
    In addition, a live scene is usually composed of multiple audio devices. When these audio devices are in use, there will inevitably be some time differences. The delay function of the audio processor can precisely solve this time difference problem, as it can make correct corrections to the time differences.
    Information Expansion: An audio processor, also known as a digital processor, processes digital signals. Its internal structure is generally composed of an input section and an output section, and its internal functions are more complete. Some come with processing modules that can be drag-and-drop programmed, allowing users to freely build systems.
    Most general digital processors use 4 to 8 full parameter equalizers. There are three adjustable internal parameters, namely frequency, bandwidth or Q value.

The difference between an audio processor and an effector
    Effectors are classified into two types based on their principles: analog effectors and digital effectors. Inside the analog effect unit are analog circuits, which are used to process sound. The inside of a digital effector is a digital circuit, which is used to process sound. The most important component of the digital circuit in the digital audio effector is, specifically, the digital audio processor. So it can be said that the digital audio processor is part of the effects unit (digital effects unit). The digital audio processing system focuses on the methods, rules and utilization of audio information acquisition, representation, transmission and processing (encoding, transformation, recognition, synthesis, understanding and storage), including the input module, output module, access/communication module, control and storage module, as well as the core audio processing module.
1、Audio input
    Audio input involves putting the sound signal to be processed into the system. Sound signals can be collected through devices such as tape recorders, video recorders, televisions, and microphones.
2、Audio output
    The main function of audio output is to restore the audio signal processed by the system into a form that users can perceive. Speakers, audio equipment and headphones are commonly used audio output devices.
3、Control and Storage
    Control equipment is mainly used to control audio processing devices during the processing, such as keyboards, mice, various switches, etc. Storage devices are mainly used to temporarily or permanently retain audio signals themselves and related information during processing, such as various RAM, ROM, hard disks, flash memory, optical discs, etc.
4、Access/Communication
    The operation of access and communication enables users to retrieve or send the processed or further processed audio signals into the audio processing equipment as needed. Access refers to local operations, such as CDS or hard disks; Communication refers to remote access operations, such as those based on local area networks or Inemet, etc.
5、Audio processing
    Audio processing is divided into two categories: software and hardware. In a computer, audio time processing (reverberator and delay unit), timbre processing (equalizer and exciter), and dynamic processing (noise gate and compressor) are achieved through software or hardware. Common audio processing software such as GoldWave, Adobe Audition, etc., and hardware such as sound cards, dedicated DSPS, etc.
