Praat 3.9, 18 October 2000
Editors:
- • Shift-click and shift-drag extend or shrink selection in editor windows.
- • 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.
- • LongSoundEditor and TextGridEditor: write selection to audio file.
- • 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, μ-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, μ-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: χ2, 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
- • Tutorials on all subjects available through Intro.
