One of the types of objects in PRAAT.
An object of type MelSpectrogram represents an acoustic timefrequency representation of a sound: the power spectral density P(f, t).It is sampled into a number of points around equally spaced times t_{i} and frequencies f_{j} (on a Mel frequency scale).
The mel frequency scale is defined as:
mel = 2595 * log10 (1 + hertz / 700), 
and its inverse is:
hertz = 700 * (10.0^{mel / 2595.0}  1). 
With Inspect you will see that this type contains the same attributes a Matrix.
