Description Usage Arguments Value Author(s) References Examples

Perform frequency scale conversions between Hertz, Bark- and different variants von the Melscale.

bark2hz(z)
hz2bark(f)
hz2mel(f, htk = FALSE)
mel2hz(z, htk = FALSE)

`f`	Frequency in Hertz
`z`	Frequency in the auditory frequency scale
`htk`	Use the HTK-Melscale (`htk = TRUE`) or Slaney's Melscale from the Auditory Toolbox (`htk = FALSE`)

The value of the input in the target frequency scale.
