One of the types of objects in PRAAT.
An object of type FormantFilter represents an acoustic time-frequency representation of a sound: the power spectral density P(f, t), expressed in dB's. It is sampled into a number of points around equally spaced times ti and frequencies fj (on a linear frequency scale).
With Inspect you will see that this type contains the same attributes a Matrix.
