What Is A DSP Audio

Even though the digital signal processor has been around for a very long time, the audio signal industry is starting to make it a very essential feature or component in its audio product. DSP audio as it is commonly called is not just any hardware, and there is a lot to learn about this device. What is a DSP audio? What are its functions? How do you get the best out of the DSP audio device and more is what this post is here to talk to you about, so read this post today.

You might be confused what the term DSP means if it is your first time to come across it, but it is a self-explanatory term which means digital signal processor. This is a high quality technology that is commonly found in so many devices like vehicle entertainment systems, studio audio gear, smart speakers, smartphones, and even headphones. It is considered as the cornerstone or foundation of so many modern products you will find on the market today.

You might have knowledge of what a CPU’s processor is back in your school days, and digital signal processors on the other hand are designed to help with number-crunching digital signals just like in audio. Performing mathematical functions like subtraction and addition is what the digital signal processor is designed to do, and they do this at a very high speed using a smaller amount of energy.

One thing about the digital signal processors is the fact that they come in variety of sizes, performance points, and prices, and this explains their presence in professional audio equipment, car multi-channel processors, low and tiny chips found in speakers for smart voice recognition function. There are so many things you can achieve using the digital signal processor, and enhancing execution of audio-related algorithm using less power is one of them.

Let us break down what the digital signal processor means some more. It might come as a surprise to you when you realize that the DSP component can be found in smartphones. Recognizing your voice for google voice function, controlling noise cancellation, enhancing bass boost, and helping to decode MP3 files are all functions of the digital signal processor installed inside of your phone.

Do you have an idea that the digital signal processor can change your listening experience forever? I bet you had no idea. Offering a top class processing power that works for a wide and high quality range of effects is what the digital signal processor is designed to offer. The fact that it consumes less amount of power makes it unique, and consuming less amount of power means you will enjoy prolonged battery life.

Just because the digital signal processor has all this functions doesn’t mean you will find it on just any devices specifications sheet. When used in headphones, they are found inside of a bluetooth chip capability. Other devices on the other hand are known to provide other capabilities like speaker capability, DAC, and ADC alongside the digital signal processor on a single chip.

The digital signal processor is one topic that even experienced professionals get overwhelmed when reading about them. When learning about digital signal processors, it is very important that you have a very good idea about the components that make it up. This is what we want to show to you next in this interesting post, so without wasting further time, below are the key components that make up the digital signal processor.

Components Of The Digital Signal Processor

  • The program memory
  • The data memory
  • The computer engine
  • The input/Output

The role of the program memory isn’t difficult or challenging, as all that it is tasked to do is store programs the digital signal processors uses for processing its data. The role of the data memory isn’t so different from that of the program memory as it is tasked with storing information needed by the digital signal processor. Accessing data from the data memory, program from the program memory, and performing math processing is the role of the computer engine.

Finally, the input and output is designed to perform a range of functions that connects the digital signal processor to the outside world. You can see from all we have about the digital signal processor that is a very core or vital part of any system. The information from a digital signal processor helps in controlling video compression, home theater systems, telephone, and security by a computer.

The signals from a DSP device gets compressed faster so it can be transferred from efficient and quickly from one place to the other. A very crucial fact about the digital signal processor you must is the fact that its signals can be enhanced. Manipulating or enhancing the signals from a DSP device helps in improving the quality of the signal, making sure that the information provided cannot be easily sensed by humans.

This tells you how intelligent digital signal processors are, even though real world signals gets to be processed in their analog form, you have the advantage of accuracy and high speed when you process signals digitally. The fact that a digital signal processor is easy to program makes it easy to use in several types of application, and all of these makes the use of digital signal processors more common in the world of car audio components.

There are so many modern cars that have digital signal processors in them, but there are several other cars that do no come with digital signal processors. Now that we have mentioned using digital signal processors in cars, let us throw more light on what they really do.

Digital Signal Processors In Cars

Installing a digital signal processor in a car audio’s system comes with a lot of advantage and benefits. You will have a great amount of control over output and the entire system is one of such benefit, and the fact that it offers all the vital hardware required for an audio system to function at its peak is yet another reason why you should not miss out on installing a digital signal processor in your car today.

If you want to get the best out of whatever you are listening to then you should consider installing a digital signal processor inside your car, but do not confuse its benefits as a requirement for having it installed in your car audio system. There are car audio systems that are designed to sound very good without the help of any other component or hardware, and this is because they have an EQ in the head unit that handles tweaking of audio content.

Bearing this in mind, we just want to make it clear that an audio system can sound very great without having a digital signal processor inside of it. Adding a digital signal processor to your car audio setup is simply enhancing the system you already have. This means that adding a digital signal processor would not make your car audio quality sound excellent all of a sudden.

The only benefit it offers is making sure you have additional control over the signals coming out from your audio system. This is why professionals are of the opinion that adding a digital signal processor to an audio car setup that already sounds good is just a way of fine-tuning and gaining precise control over the entire system. Another fact you should know is that digital signal processors are easier to install compared to amplifiers.

This is why most modern amplifiers today come with digital signal processors installed inside of them. This has left people wondering if they should just get an amplifier and DSP device separately, or shop for an amplifier that already has a digital signal processor inside of it.
