This paper describes the design and implementation of a FIR based 20-band stereo audio equalizer that offers good spectral selectivity and phase response. The underlying theory of fast filtering in the frequency domain is addressed, the architecture of the DSP system using a single TI TMS320C31processor is presented, the functionality of the interface, either software-based or hardware-based, is described, and a few test results are presented and discussed.
