  • identifying the first audio signal;

    determining whether a quality of the first audio signal is below a quality threshold, said determining comprising;

    obtaining a portion of a second audio signal having a higher quality than the first audio signal from a second audio source;

    time aligning the obtained portion of the second audio signal and the identified first audio signal; and

    calculating a metric based on a difference between the obtained portion of the second audio signal and the identified first audio signal, wherein the metric is calculated in accordance with;


    Sq=(H*H+O*O)/(H−

    O
    )*(H−

    O
    )where H is the obtained portion of the second audio signal, O is the identified first audio signal and Sq is the quality of the identified first audio signal; and
