Abstract :
Describes the design of an audio signal processor system using a digital signal processor (DSP). The use of a high speed DSP with 24-bit wide data buses allows the implementation of many digital audio algorithms. These algorithms cover standard audio functions: equalizer, volume and balance control, as well as special functions: reverberations, base width enhancement, adaptive equalizer, dynamic range control, etc. The special audio functions are only available through the use of digital signal processing routines.<>
