Praat Changelog

What's new in Praat 6.4.07

Mar 18, 2024
  • The command Sound & Pitch: To PointProcess (cc), which is also used when computing the times of pulses in the Sound window, could cause Praat to freeze when the pitch ceiling (and the measured pitch) were very high; this problem existed since at least 2001.
  • eSpeak: new version, with e.g. Tigrinya.
  • Support for 119-dpi graphics on Windows.
  • Repaired a bug that could cause the Artword windows to crash if the Time field was left empty.

New in Praat 6.4.06 (Feb 26, 2024)

  • Sound files on Windows: corrected a bug (existing since July 2021) that prevented reading FLAC files with special characters in their names.
  • FormantPathEditor without Sound: corrected several bugs that caused Praat to crash (such as Formant listing, using the Pitch menu...).
  • Spectrogram painting: improved painting of very quiet spectrograms at extreme dynamic ranges.
  • Scripting: folderExists.
  • Scripting: home-relative paths (such as ~/sounds/*.wav) in more locations, such as fileNames$#, Create Strings as file list..., and createFolder.

New in Praat 6.4.05 (Jan 29, 2024)

  • Many typos in manual.
  • Made TIMIT label files readable on Windows.
  • Prevented 8000 files from being read at start-up.
