Abstract

This paper addresses the implementation of a real-time 20-band adaptive digital audio equalizer for room equalization. The system has been implemented on a TMS320C6711 DSP platform and performs adaptive filtering using techniques of fast filtering in the frequency domain that include an adaptation procedure. The paper explains how the structure of a previously designed graphic equalizer has been improved to support adaptivity, describes its operation as well as its functionality based on a graphical user interface, and presents the results of tests that have been conducted to optimize its performance.
