Abstract
A method and apparatus for processing audio signals. One system includes a communication device including a transceiver configured to send and receive audio data, and a microphone configured to convert sound waves to a first audio signal. A speaker is configured to convert received electrical signals to an acoustic output and is configured to convert sound waves to a second audio signal. An electronic processor connected to the microphone and the speaker is configured to receive the first audio signal from the microphone, receive the second audio signal from the speaker, determine a correlation value between the first audio signal and the second audio signal, and compare the correlation value to a correlation threshold. In response to the correlation value being below the correlation threshold, the electronic processor generates an output signal based on the first audio signal and the second audio signal, and transmits the output signal.
