It is not clear what exactly the parameters signal_window_size and averager_window_size do:

signal_window_size: Number of samples which will be averaged in order to prevent noise ... should be very small for high Signal frequencies. Having a big value here can nullify any high frequencies on the signal.

averager_window_size: Number of data-chunks (after avergaing) for which the frequency (number of 0 transitions) will be calculated at once ?? Not clear to me what is the purpose.
