# nearest_k_p

ShortTimeFFT.nearest_k_p(k, left=True)

  Return nearest sample index k_p for which t[k_p] == t[p] holds.

  The nearest next smaller time sample p (where t[p] is the center position of the window of the p-th slice) is p_k = k // `hop`. If `hop` is a divisor of k then k is returned. If left is set then p_k * `hop` is returned else (p_k+1) * `hop`.

  This method can be used to slice an input signal into chunks for calculating the STFT and iSTFT incrementally.
