Praat 4.0, 15 October 2001

Editors:

• Simplified selection and cursor in editor windows.

• Spectrogram, pitch contour, formant contour, and intensity available in the Sound, LongSound, and TextGrid editors.

• TextGrid editor: additions and improvements.

• Log files.

Phonetics library:

• ExperimentMFC: multiple-forced-choice listening experiments.

• Sound: To Pitch (ac)...: pitch contour less dependent on time resolution. This improves the constancy of the contours in the editors when zooming.

• TextGrid: additions and improvements.

• Sounds: Concatenate recoverably. Creates a TextGrid whose interval labels are the original names of the sounds.

• Sound & TextGrid: Extract all intervals. The reverse of the previous command.

• Filterbank analyses, MelFilter, BarkFilter and FormantFilter, by band filtering in the frequency domain." )

• Cepstrum by David Weenink: MFCC, LFCC. Cepstrum object is a representation of the complex cepstrum.

• Intensity: To IntensityTier (peaks, valleys).

• Replaced Analysis and AnalysisEditor with Manipulation and ManipulationEditor.

Phonology library:

• PairDistribution: Get percentage correct (maximum likelihood, probability matching).

• OTGrammar & PairDistribution: Get percentage correct...

Graphics:

• Improved spectrogram drawing.

• Special symbols: háček.

• Macintosh: improved screen rendition of rotated text.

Audio:

• Macintosh: support for multiple audio input devices (sound cards).

Statistics and numerics library:

• More statistics by David Weenink.

• Improved random numbers and other numerical stuff.

• Regular expressions.

Scripting:

• Formatting in variable substitution, e.g. 'pitch:2' gives two digits after the decimal point.

• Added fixed$ () to scripting language for formatting of numbers.

Documentation:

• Multidimensional scaling tutorial.

• Enabled debugging-at-a-distance.
