MelSpectrogram

One of the types of objects in Praat.

An object of type MelSpectrogram represents an acoustic time-frequency representation of a sound: the power spectral density P(f, t).It is sampled into a number of points around equally spaced times ti and frequencies fj (on a Mel frequency scale).

The mel frequency scale is defined as:

mel = 2595 * log10 (1 + hertz / 700),

and its inverse is:

hertz = 700 * (10.0mel / 2595.0 - 1).
