pydsm.audio_weightings.f_weighting¶

pydsm.audio_weightings.f_weighting(f, normal=True, power=True)¶

Returns the F-weighting as a function of frequency.

Parameters:

Parameters:	f : float or array of floats frequency where the weighting function is computed normal : bool whether the function should be normalized to have unit gain at 1 kHz. power : bool whether the function should express the weighting in terms of acoustic power or signal amplitude
Returns:	w : float or array of floats value of the weigting function

f : float or array of floats

frequency where the weighting function is computed

normal : bool

whether the function should be normalized to have unit gain at 1 kHz.

power : bool

whether the function should express the weighting in terms of acoustic power or signal amplitude

Returns:

w : float or array of floats

value of the weigting function

Notes

The F-weighting function is documented in [R6].
