Break Through Car Audio with DSP 910792

The authors have designed digital audio signal processing circuitry having the following features for High Fidelity sound reproduction. The digital audio signal processing circuitry is suitable for car audio equipment.
  • Digital parametric equalizer for better frequency response
  • Sound field controller for creating spatial impressions
  • Linear Phase digital crossover network
  • Time alignment controller for adjusting the phase difference which is caused by the distance difference of listener and loudspeakers
It is difficult to produce practical circuit incorporating the above features using analog signal processing circuits.
The authors have designed circuits having these features using digital signal processing.
