What is DSP in a car?
1 Answers
DSP in a car stands for Digital Signal Processor for audio. Due to the limited space in a car, the numerous speakers, their less-than-ideal distribution, the irregular shape of the car interior, strong glass reflections, and severe acoustic defects, coupled with the limitations of speaker frequency response, enclosure materials, and space, the sound reaching the human ear can be significantly distorted. By digitizing the audio signal and using digital technology to correct these defects—including adjustments like EQ, crossover, delay, and phase—it is possible to produce a high-quality sound with accurate sound imaging, strong spatial presence, high resolution, and a balanced frequency response across highs, mids, and lows, tailored to human hearing preferences.
