def getRMS(data):

    ''''Compute and return the audio power ("loudness").
    Uses numpy.std() as RMS. std() is same as RMS if the mean is 0,
    and .wav data should have a mean of 0.
    Returns an array if given stereo data (RMS computed within-channel).
    `data` can be an array (1D, 2D) or filename.
.wav format only.
    data from .wav files will be normalized to -1..+1 before RMS is computed.'

 Give me a Python program to compute and return the audio power ("loudness")?
