1. A method comprising:

  • receiving an audio output signal (OS) from a media system and passing the audio output signal (OS) to an audio buffer;

    receiving an audio input signal (IS) from an input system and passing the audio input signal (IS) to the audio buffer;

    converting the audio output signal (OS) and the audio input signal (IS) for comparison;

    comparing the converted audio output signal (OS) stored in the audio buffer with the converted audio input signal (IS) stored in the audio buffer to determine a probability and intensity of audio signal overlap between the converted audio output signal (OS) and the converted audio input signal (IS), the comparing using signal processing to detect a magnitude and offset of any matching signals present in the audio buffer;

    generating audio overlap data (OD) from the probability and intensity of audio signal overlap, the audio overlap data (OD) representing a magnitude and offset of the audio signal overlap; and

    using the audio overlap data (OD) to perform an audio signal compensation function on the audio input signal (IS).
