Introduction to audio and video processors

A digital audio processor is a digital audio signal processing device that can convert analog signals input from multiple channels into digital signals and perform a series of tunable algorithm processing to meet application requirements such as improving sound quality, matrix mixing, noise reduction, echo reduction, and feedback reduction. The processed digital signals are then output as multi-channel analog signals through digital-to-analog conversion.

The main functions of digital audio processors include:

Input part:

Input gain control (INPUTGAIN)

Input equalization (several bands of parameter equalization) adjustment (INPUTEQ)

Input delay adjustment (INPUTDELAY)

Input polarity (phase) conversion (inputpolarity)

Output part:

Signal input distribution routing selection (ROUNT)

High pass filter (HPF)

Low pass filter (LPF)

Equalizer (OUTPUTEQ)

Polarity (polarity)

Gain (GAIN)

Delay (DELAY)

Limiter start level (LIMIT)

DSP technology:

Digital audio processors usually use advanced digital signal processing (DSP) technology to provide efficient audio processing capabilities and ensure the accuracy and purity of sound quality.

Built-in multiple audio processing algorithms, including multiple EQ, dynamic compression, limiter, delay, etc., to achieve full-band balance adjustment, dynamic loudness control, echo cancellation, noise reduction and other functions.

Flexibility and scalability:

Users can control and configure through the USB interface, or expand more functions through the programmable interface.

Supports a variety of audio input and output interfaces to meet different audio processing needs3.

Application scenarios:

Applicable to almost all audio processing scenarios such as recording studios, playback halls, cinemas, stadiums, etc., and can easily achieve high-quality audio processing.

Product examples:

SP480 digital audio processor: Equipped with the latest SHARC ADSP-21488 400MHz floating-point DSP, it provides excellent processing capabilities and ensures efficient and accurate audio control.

MAXIDRIVER3.4 digital audio processor: A full-featured digital audio processor that integrates gain, noise gate, parameter equalization, frequency division, compression limiting, and delay.

Digital audio processors have a wide range of applications in the field of audio processing, from professional audio systems to home theaters, and can provide high-quality audio processing effects. Choosing a suitable digital audio processor can be determined based on specific needs and budget.
