    <title>Microphone</title>
    <p>
        If you have a microphone with reasonably flat response you can use it together
        with a pink noise test signal to estimate how flat is your audio setup frequency
        response.

            The amount of time the microphone signal will be measured. Higher values will
            reduce noises.

        <p>
            Saves the last measurement to be used as background noise. Usually you would use
            this before turning on the pink noise.

        <p>
            Subtract the stored background noise from the measurement.
