An audio processor is a chip used to analyze and modify the output of digital or analog audio devices, delivering better audio performance or intelligent functions. It can be found in a variety of sizes, prices and performance points, from multi-channel processors in cars and professional studio equipment to tiny low power chips for smart speaker voice recognition.
Adding quality speakers and amplifiers to your car can really improve your listening experience, but factory stereos often have built-in sound shaping and equalization designed to limit bass output and prevent your aftermarket speakers from producing the full range of sparkling high-frequency sounds, thundering bass, and coherent natural-sounding vocals you want for your vehicle. An audio processor removes these sound-shaping limitations to give you the best sound possible from your aftermarket system.
When you listen to music through your car's factory stereo, your ears can pick up unwanted noise from the environment or other sources. An audio processor can reduce this noise by using active noise control to create a signal that is identical to the unwanted sound but with the opposite polarity, canceling it out.
The volume level of an audio signal can vary greatly over time, as the listener moves around or different devices are used in the environment. Dynamic effects monitor the volume and adjust it automatically based on various factors to ensure that your audio is always playing at the right level.
What Is a Sound Processor?
A sound processor, or digital signal processor (DSP) as they are also known, is an electronic chip that manipulates number-crunching digital signals like audio. It’s a common feature in headphones, smart speakers, car entertainment systems, professional studio equipment and much more.
A digital sound processor is a piece of hardware that can be used to strip away the factory-supplied equalization that comes with a car stereo and send the audio signals to aftermarket amplifiers and speakers to make them perform more accurately. They can remove all the preprocessing that car makers do when they design their in-car sound system, enabling your music to play with a natural balance of sparkling highs, thundering bass and coherent vocals you’ll love.
A quality sound processor will strip away all the factory-supplied equalization that comes in your vehicle’s audio system and send the clean signal to your aftermarket amplifiers and speakers. The result is an enhanced audio experience that will match your driving conditions and the environment inside of your vehicle.
It’s important to find a good quality sound processor because not all sound processors will provide an excellent upgrade to your car’s in-car audio. So, you have to be sure that you pick one that has the right features and a solid warranty. It’s best to shop around at a specialist mobile enhancement retailer where they have the DSP in a demo vehicle and can show you how each step will improve the performance of your in-car audio.
Digital Signal Processors
Digital signal processors (DSPs) are the core of most modern audio equipment, including headphones, smart speakers, studio audio gear, and vehicle entertainment systems. They run the math that lets your Apple AirPods Pro or Sony 360 Reality Audio amplify bass to match your favorite track, recognize voice commands for Google Assistant, and even tune the sound of your in-home home cinema speaker system to the way you listen to music.
A DSP enables the performance of sound-shaping functions that are too expensive or inefficient for mass-produced, OEM speakers. It also allows for the sonic improvements that are often necessary to overcome the limitations of factory car stereos.
DSPs can be found in a wide range of prices and performance points, from multi-channel processors for car audio systems and professional studio equipment to tiny low power chips for smart speaker voice recognition. They speed up the execution of complex algorithms while consuming less power than a typical CPU.
The first dedicated loud speaker processor appeared in the professional sound reinforcement market in 1979. Meyer Sound Laboratories' UM-1 UltraMonitor was an example of the new type, and other manufacturers followed suit.
Today, a large number of signal processing vendors sell dedicated speakers processors that offer sophisticated EQ, crossover, dynamics, and system protection functions for a variety of applications. Some models have user-definable presets, while others can save their settings to internal or removable drives.
