Description:
 def calculate_nfft(samplerate, winlen):
 """Calculates the FFT size as a power of two greater than or equal to the number of samples in a single window length. Having an FFT less than the window length loses precision by dropping many of the samples; a longer FFT than the window allows zero-padding of the FFT buffer which is neutral in terms of frequency domain conversion. :param samplerate: The sample rate of the signal we are working with, in Hz. :param winlen: The length of the analysis window in seconds.
