Digital Frequency Shifting For Electroacoustic Feedback Suppression
In the field of electroacoustic installations, several more or less sophisticated methods may be used to avoid annoying feedback “howl” and boost the potential acoustic gain (PAG) by a few dB. This paper discusses the use of a digital frequency shifter instead of more popular narrow-band filtering techniques. The device has been implemented using a readily available programmable DSP platform and its efficiency has been proven by measurements in various environments.
