-
• Grouped editors can have separate zooming and scrolling (FunctionEditor preferences).
-
• Cursor follows playing sound in editors; interruption by Escape key moves the cursor.
-
• TextGridEditor: optimized for transcribing large corpora: text field, directly movable boundaries, more visible text in tiers, SpellingChecker, type while the sound is playing, complete keyboard navigation, control font size, control text alignment, shift-click near boundary adds interval to selection.
-
• Stereo display in LongSound and TextGrid editors.
-

-
• SoundEditor: added command Extract selection (preserve times).
-
• IntervalTierEditor, DurationTierEditor.
-
• Added many query commands in editors.
Phonetics library:
-
• Sound: To Formant...: sample-rate-independent formant analysis.
-
• Sound: To Harmonicity... (glottal-to-noise excitation ratio).
-
• Pitch: support for ERB units, draw all combinations of line/speckle and linear/logarithmic/semitones/mels/erbs, optionally with TextGrid, Subtract linear fit.
-
• Spectrum: Draw along logarithmic frequency axis.
-
• TextGrid: modification commands, Extract part, Shift to zero, Scale times (with Sound or LongSound).
-
• Matrix: To TableOfReal, Matrix: Draw contour....
-
• Concatenate Sound and LongSound objects.
-
• File formats: save PitchTier in spreadsheet format, read CGN syntax files (XML version), text files now completely file-server-safe (independent from Windows/Macintosh/Unix line separators).
Statistics and numerics library:
-
• Principal component analysis.
-
• Discriminant analysis.
-
• Polynomial: drawing, root finding etc.
-
• TableOfReal: Draw box plots....
-
• Covariance: To TableOfReal (random sampling)....
-
• SSCP: Get sigma ellipse area....
-
• Query DTW for “weighted distance” of time warp.
-
• Distributions: To Strings (exact)...
-
• Strings: Randomize
Phonology library:
-
• OTGrammar: To PairDistribution.
Graphics:
-
• Full support for colour inkjet printers on Windows and Macintosh.
-
• Full support for high-resolution colour clipboards and metafiles for Windows and Macintosh programs that support them (this include MS Word for Windows, but unfortunately not MS Word for Macintosh).
-
• Colour in EPS files.
-
• Interpolating grey images, i.e. better zoomed spectrograms.
-
• Linux: support for 24-bits screens.
Audio:
-
• Asynchronous sound play.
-
• Linux: solved problems with /dev/mixer (“Cannot read MIC gain.”) on many computers.
-
• Added possibility of zero padding for sound playing, in order to reduce clicks on some Linux and Sun computers.
-
• LongSound supports mono and stereo, 8-bit and 16-bit, u-law and A-law, big-endian and little-endian, AIFC, WAV, NeXT/Sun, and NIST files. •vRead two Sounds from stereo file... supports 8-bit and 16-bit, u-law and A-law, big-endian and little-endian, AIFC, WAV, NeXT/Sun, and NIST files.
-
• SoundRecorder writes to 16-bit AIFC, WAV, NeXT/Sun, and NIST mono and stereo files.
-
• Sound & LongSound: write part or whole to mono or stereo audio file.
-
• Read Sound from raw Alaw file.
-
• Artword & Speaker (& Sound) movie: real time on all platforms.
Scripting:
-
• Formulas 5. Mathematical functions: added statistical functions: i2, Student T, Fisher F, binomial, and their inverse functions.
-
• Windows: program
praatcon
for use as a Unix-style console application.
-
• Windows and Unix: Praat can be run with a command-line interface without quitting on errors.
-
• Unix & Windows: can use <stdout> as a file name (supports pipes for binary data).
-
• sendpraat now also for Macintosh.
-
• sendsocket.
-
• Read from file... recognizes script files if they begin with “
#!
”.
-
• Script links in ManPages.
Documentation
-
