What was new in 3.5?

Praat 3.5, 27 May 1997

New editors:

TextGridEditor replaces and extends LabelEditor: edit points as well as intervals.
AnalysisEditor replaces and extends PsolaEditor: view pitch, spectrum, formant, and intensity analyses in a single window, and allow pitch and duration resynthesis by overlap-add and more (would be undone in 3.9.19).
SpectrumEditor allows you to view and edit spectra.

Praat shell:

History mechanism remembers all the commands that you have chosen, and allows you to put them into a script.
ScriptEditor allows you to edit and run any Praat script, and to put it under a button.
• All added and removed buttons are remembered across sessions.
ButtonEditor allows you to make buttons visible or invisible.

Evaluations:

• In his 1996 doctoral thesis, Henning Reetz compared five pitch analysis routines; Sound: To Pitch (ac)... appeared to make the fewest errors. H. Reetz (1996): Pitch Perception in Speech: a Time Domain Approach, Studies in Language and Language Use 26, IFOTT, Amsterdam (ICG Printing, Dordrecht).

Documentation:

• 140 more man pages (now 330).
• Tables and pictures in manual.
• Printing the entire manual.
• Logo.

New types:

• Labelling & segmentation: TextGrid, IntervalTier, TextTier.
• Analysis & manipulation: Analysis.
• Statistics: TableOfReal, Distributions, Transition

File formats:

• Read and write rational numbers in text files.
• Read 8-bit .au sound files.
• Read and write raw 8-bit two’s-complement and offset-binary sound files.

Audio:

• 16-bit interactive Sound I/O on Mac.
• Record sounds at 9.8 kHz on SGI.

New commands:

• Two more pitch-analysis routines.
• Sound to PointProcess: collect all maxima, minima, zero crossings.
• PointProcess: set calculus.
• TextGrid: extract time-point information.
• Compute pitch or formants at given time points.
• Put pitch, formants etc. in tables en get statistics.
• Many more...

Macintosh:

• 16-bit interactive sound I/O.
• Fast and interpolating spectrogram drawing.
• Phonetic Mac screen font included in source code (as a fallback to using SIL Doulos IPA).
• Keyboard shortcuts, text editor, help under question mark, etc.
