Thanks to Nick for laying the foundation and writing the code on the formulas. Corrected another bug in the new Sound: To TextGrid (silences).Attached is a revision to Nick’s script for gathering data.Sound window: the pitch drawing method is Curves, Speckles, or Automatic.Corrected yet another bug in the new Sound: To TextGrid (silences).Linux: corrected a bug introduced in 4.5.02 that prevented sounds from playing and other weird things.Table: added independent-samples t-test.Sound: Change gender.: corrected a bug that often caused a female-to-male conversion to sound monotonous.Macintosh scripting: European symbols such as ö and é and ç are now allowed in file names in scripts and in MacRoman-encoded file names sent by other programs through the sendpraat subroutine.SSCP: Draw confidence ellipse: corrected a bug that would sometimes not draw the ellipse when N was very large.Scripting: removed several kinds of restrictions on string length.Support for 32-bit floating-point WAV files.Phonetic symbols: ˈprimary stress and ˈseconˌdary stress.Macintosh: playing a sound now uses CoreAudio instead of SoundManager.sendpraat scripts correctly wait until sounds have played.Linux: made Create Strings as file list.Linux: better scroll bars in object list for Lesstif (Debian).ManPages allow picture scripts with separate object lists.Macintosh: recording a sound now uses CoreAudio instead of SoundManager, " for more compatibility with modern recording devices, and the possibility to record with a sampling frequency of 96 kHz.Sound objects can be stereo, for better playback quality (most analyses will work on the averaged mono signal).Made cross-correlation pitch analysis as fast as it used to be before 4.5.11.Scripting: removed a bug introduced in 4.5.06 that caused some variables not to be substituted.For stereo sounds, spectrogram analysis is based on power density averaged across channels (rather than on the power density of the channel average).For stereo sounds, pitch analysis is based on correlations pooled over channels (rather than on correlations of the channel average).Scripting: some new predefined string variables like preferencesDirectory$.The workaround is to temporarily disable file info tips when the file selector window is on the screen. Windows XP: worked around a bug in Windows XP that could cause Praat to crash when the user moved the mouse pointer over a file in the Desktop in the file selector.Linux: made it more likely to find the correct fonts.Sound-to-Intensity: made resistant against undefined settings.Picture window: keyboard shortcut for Erase all.Macintosh: better image drawing (more grey values).Windows audio playing: attempt at more compatibility with Vista.Scripting: allow comments with “ #” and “ ” in forms.PitchTier Formula: guard against undefined values.Scripting: allow assignments like pitch = To Pitch.Scripting: removed a bug that could make selection checking (in command windows) unreliable after a script was run.OT learning: corrected HarmonicGrammar (and LinearOT) learning procedure to the stochastic gradient ascent method applied by Jäger (2003) to Ma圎nt grammars.Macintosh: improved drawing of spectrograms for printing and clipboard (this was crippled in 4.5.18, but now it is better than before 4.5.18).Macintosh: much smaller sizes (in kilobytes) of spectrograms for printing and clipboard this improves the compatibility with other programs such as Microsoft Word for large spectrograms.OT learning: added decision strategy MaximumEntropy this has the same harmony determination method as Harmonic Grammar (include the additive constraint noise), but there is some more variability, in that every candidate gets a relative probability of exp(harmony).OT learning: OTGrammar window shows harmonies. Sound files: reading FLAC audio files (implemented by Erez Volk).
