One of the types of objects in PRAAT.
An object of type BarkSpectrogram represents an acoustic time-frequency representation of a sound: the power spectral density P(z, t). It is sampled into a number of points around equally spaced times ti and frequencies zj (on a Bark scale).
The bark to hertz transformation is defined as:
|hertz = 650.0 * sinh (bark / 7.0),|
while its inverse is defined as:
|bark = 7.0 * log (hertz/650 + sqrt (1 + (hertz/650)2).|
With Inspect you will see that this type contains the same attributes a Matrix object.
