What is a Car Audio DSP?

[VanEloise]

DSP, also known as an audio processor, handles digital signal processing. Its internal structure typically consists of input and output sections. It offers more comprehensive functionality, with some models featuring drag-and-drop programmable processing modules, allowing users to freely configure the system. Here are the functional features of DSP: 1. Input Gain: Controls the input level of the processor. The adjustable range is generally around 12 decibels. 2. Input Equalization: Most digital processors use 4-8 full parametric equalizers, with three adjustable internal parameters: frequency, bandwidth or Q value, and gain. 3. Input Delay: This function adds some delay to the input signal as soon as it enters the processor. It is commonly used for overall delay adjustment when the processor and its controlled speakers serve as auxiliary devices. 4. Input Polarity Inversion: Allows the polarity phase of the entire processor to switch between positive and negative, eliminating the need for rewiring.
