Signal Processors

One car audio component that gets mentioned more often than it might be understood is the signal processor. A signal processor controls the signal sent to the speakers in order to produce better sound. Car Audio Signal Processors can range from something as simple as the tri-way crossover circuit in a car amplifier to something as complex as a dedicated signal processor. The key to a high-end car signal processor is the Digital Signal Processor (DSP). A DSP is essentially a computer designed specifically for processing data streams on the fly, and they are very common in both audio and video applications.


Car Audio Signal processors can do many things to affect the sound the user hears, but it cannot do everything because the signal processor does not produce the sound directly. The job largely falls on the speakers. Even the best signal processor can only deliver the best sound the speakers can create, and low-end or factory speakers are generally unable to take full advantage of the perfectly balanced clean signal provided by a high-end signal processor. If you are seeking to buy a high-end signal processor you should also take the time to make sure your speakers are capable of producing clean enough sound to take full advantage of it.
