What Is a Digital Signal Processor?
Decades ago, companies took advantage of increases in computer power to create an integrated circuit (IC) called a digital signal processor (DSP). These ICs could perform adjustments to an analog signal in the digital domain, making everything very precise and repeatable. These days, almost everything has a DSP chip in it. Your smartphone, laptop computer, smart speaker and, of course, the stereo that came with your vehicle are just a few examples.
These DSP chips either include an analog-to-digital converter or work with external units to convert the analog audio signal into a series of ones and zeroes that represent that information. The processor can then apply equalization, filtering, delay and amplitude adjustment to the mathematical representation of the waveform. Once the processing is completed, a digital-to-analog converter transforms the data stream back into an analog signal that can be fed to the amplifier.

A key benefit of digital processing is its accuracy. If the calibration process for your vehicle requires a reduction in amplitude of 3.2 dB, centered around a frequency of 1.2 kHz with a Q-factor of 5.2, the software will allow that to be applied. Likewise, crossover frequencies are very precise, helping to ensure that the output of one speaker will blend smoothly with that of a speaker operating in an adjacent frequency range. These settings don’t vary over time or temperature. The result is predictable and repeatable performance that never needs tweaking.
Another massive benefit of a DSP is the ability for it to store the digital data for a predetermined amount of time before converting it back to analog. This programmable delay can be used to adjust the arrival times of sounds from different speakers in your vehicle so that everything arrives at the listening position all at once. When combined properly with level-matching and equalization, the result is an impressively accurate and realistic listening experience with a great soundstage and excellent imaging.

Tuning the sound by softeware or app,you can easily achieve any effect you want, and adjust it according to your own preferences.moreover,It provides additional expansion functions, such as adding a subwoofer or some tweeters, center speakers by choose proper models.
First and foremost, nothing should stand out in terms of frequency response. The balance between the highs, midrange and midbass should be smooth and natural. Both male and female voices should sound realistic and lifelike. Instruments should also sound genuine and authentic.
Depending on the listening preferences you provided to your technician before he or she began calibrating the system, you’ll either have a soundstage that spans the width of the dash, or you’ll be centered in the middle of the listening experience. Some may refer to this as a concert or a club-style configuration. In no circumstances should the sound seem to come from one side of the vehicle or the other.
Another tuning preference focuses on where the center of the soundstage is located on the dash. The most realistic listening experience should have the center of the soundstage placed in the center of the windshield under the rearview mirror. This configuration provides equal spacing on either side of the center image for other performers and instruments. Some people, including those designing many factory-installed systems, prefer to place the center image in front of the driver. There’s no right or wrong in this case – the decision is yours, and you should make your preference clear to the person calibrating the audio system.
