pub fn mel_to_hz(mel: Smpl) -> Smpl
Expand description

Convert mel to frequency (Hz)

  • mel Input mel to convert

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

If f < 1000, f = 200 m/3. If f >= 1000, f = 1000 + (6400 / 1000) ^ ((m - 1000) / 27)
