What was new in 4.2?

What was new in 4.2?

General:

Phonetics:

Faster computation of spectrum, spectrogram, and pitch.
More precision in numeric libraries.
PitchTier: Interpolate quadratically.
TextGrids can be saved chronologically (and Praat can read that file again).
Sound editor window Time step settings...: Automatic, Fixed, and View-dependent.
Sound window: distinguish basic from advanced spectrogram and pitch settings.
Read TableOfReal from headerless spreadsheet file...: cells with strings are considered zero.
Sound window: introduced time step as advanced setting.
Sound window: reintroduced view range as advanced setting.
Ltas: Compute trend line, Subtract trend line.

Audio:

Graphics:

Better selections in Picture window and editor windows.
Picture window: better handling of rectangles and ellipses for reversed axes.
Windows: corrected positioning of pictures on clipboard and in metafiles.
Windows: EPS files check availability of Times and TimesNewRomanPSMT.
Polygon: can now also paint in colour instead of only in grey values.
Unlimited number of points for polygons in PostScript (may not work on very old printers).
Picture window: line widths on all printers and clipboards are now equal to line widths used on PostScript printers: a line with a line width of “1” will be drawn with a width 3/8 points. This improves the looks of pictures printed on non-PostScript printers, improves the looks of pictures copied to your wordprocessor when printed, and changes the looks of pictures copied to your presentation program.

OT learning:

Metrics grammar supports `impoverished overt forms', i.e. without secondary stress even if surface structures do have secondary stress.
Support for crucially tied constraints and tied candidates.
Support for backtracking in EDCD.
Queries for testing grammaticality.

Scripting:

ManPages: script links can receive arguments.
ManPages: variable duration of recording.
Support for unlimited size of script files in editor window on Windows XP and MacOS X (the Unix editions already had this).
Improved the reception of sendpraat commands on Windows XP.
