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.
