aubio_meltohz method

double aubio_meltohz(
  1. double mel
)

convert mel to frequency (Hz)

\param mel input mel

\return output frequency, in Hz

Converts a scalar from the mel scale to the frequency domain using Slaney Auditory Toolbox's implementation:

If \f$ f < 1000 \f$, \f$ f = 200 m/3 \f$.

If \f$ f \geq 1000 \f$, \f$ f = 1000 + \left(\frac{6400}{1000}\right) ^{\frac{m - 1000}{27}} \f$
