Car Audio DSP

During the 70s, significant advances were made in the field of integrated circuits (IC). Many companies used this increase in computing power capabilities to develop digital signal processor (DSP) chips. Today digital signal processor (DSP) chips are found in an array of audio devices ranging from Smart TVs, Smart Phones, Soundbars, and, yes, car audio amplifiers. Digital signal processors (DSP) are used to accurately manage the frequency as in a crossover function and manage the time domain for better phase relation between drivers and speakers. Another popular function for audio DSP is tone management, sometimes referred to as equalization. Although you can buy amplifiers that have integrated DSP modules or options as a general rule, you want the DSP processor to be a dedicated unit. This gives you the most flexibility in system design. With that said, it is important to point out that DSP is great, but at the same time, just a band-aid. Fundamental system design measures need to be taken to achieve accurate sound quality. In recent years we have seen many try to use DSP to fix severe audio issues and fail. While they are a great tool, they are no magic wand.
