Abstract
Wireless microphone signals are detected by processing an input signal to determine a number of frequency bins within a channel frequency band having an energy level above a first predefined threshold (S); identifying locations of the frequency bins having an energy level above the first predefined threshold, when the number of bins is greater than zero (S, S); for each frequency bin having an energy level above the first predefined threshold, processing signals within a narrow frequency band of the frequency bin (S); determining a number of signal peaks within the narrow frequency band that are above a second predefined threshold (S); and generating a message indicating a presence or an absence of a microphone signal based on the number of signal peaks (S, S).
