Frequency scale conversion

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

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

Value
