frequencyToWindowSize

maelzel.snd.freqestimate.frequencyToWindowSize(freq, sr, powerof2=False, factor=2.0)

Return the size of a window in samples which can fit the given frequency

Parameters:

• freq (int) – the lowest frequency to fit in the window

• sr (int) – the sampling rate

• powerof2 – if True, force the size to the next power of two

• factor – the factor used to fit to account for phase shifts. Without this the window will not fit an entire cycle of the given frequency unless the signal is in perfect sync with the window.

Return type:

int

Returns:

the size of the window in samples
