Abstract

Digital audio has become very popular in the last two decades. With the growth of multimedia systems and the World Wide Web, audio processing techniques, such as filtering, equalization, noise suppression, compression, addition of sound effects and synthesis. In this study, an audio enhancement technique using digital FIR filters is implemented. Digital filtering separate signal components based on their frequency content. So that signal can be enhanced with certain or desired frequency components using band pass digital filter. This approach is designed using Simulink and Xilinx DSP Tools, synthesized with ISE 13.2 and implemented on Virtex4 xc4vsx55-12ff1148 FPGA device. Results show the resource utilization on device using bandstop FIR filter designed by Equiripple technique.
