Design of an Automatic Feedback Detection and Elimination System

ABSTRACT

The main focus of this project is to detect and remove acoustic feedback from a digital audio signal. This project was inspired from experience with this problem in everyday situations dealing with the amplification of an audio signal using a microphone and speaker based system. The technology developed will be applicable to any digital audio signal to improve signal quality, available gain from the system, protect equipment from unnecessary strain, and protect hearing. The algorithm will involve development of C++ coding and comparison testing between the processed and unprocessed signal will show the accuracy of the feedback detection and removal.
