1 2 |

`hz` |
a frequency in Hertz (cycles per second). |

`mel` |
a frequency in mel units. |

These functions convert between the linear Hertz and psychoacoustic Mel scales. The functions use formulas provided by Rietveld & Van Heuven (2009).

A frequency of 1000 Hz equals 1000 mel. For frequencies below 1000 Hz the mel scale is approximately linear; for frequencies above 1000 Hz the mel scale is approximately logarithmic.

Transformed value(s) in mel or hertz units.
