What was new in 4.2?

## Praat 4.2, 4 March 2004

General:

  • July 10, 2003: Open source code (General Public License).

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:

  • Sun workstations: support audio servers.

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.
