What was new in 4.3?

Praat 4.3, 26 January 2005

General:

Apply button in settings windows for menu commands and in script forms.
• Info window can be saved.
• Removed 30,000-character limit in Info window.

Phonetics:

• Speeded up intensity analysis by a factor of 10 (by making its time resolution 0.01 ms rather than 0.0001 ms at a sampling frequency of 44 kHz).
• Speeded up pitch analysis and spectrogram analysis by a factor of two.
• Sound: To Spectrum... now has a reasonably fast non-FFT version.
• Calibrated long-term average spectrum (Sound: To Ltas...).
• Pitch-corrected LTAS analysis.
• Sound: Scale intensity.
• PitchTier: To Sound (sine).
• Better warnings against use of the LPC object.

Voice:

• July 9, 2004 (4.2.08): Shimmer measurements: more accurate and less sensitive to additive noise.
• More extensive voice report: pitch statistics; harmonicity.

Audio:

• Reading and opening 24-bit and 32-bit sound files (saving still goes in 16 bits).
• LongSound: save separate channels.
• Macintosh: much faster reading of WAV files.

Listening experiments:

• Subjects can now respond with keyboard presses.

Graphics:

• One can now drag the inner viewport in the Picture window, excluding the margins. This is nice e.g. for creating square viewports or for drawing a waveform and a spectrogram in close contact.
• Unix: picture highlighting as on Mac and Windows.
• More drawing methods for Sound and Ltas (curve, bars, poles, speckles).

OT learning:

• Monitor rankings when learning.
• OTGrammar: Remove harmonically bounded candidates...
• OTGrammar: Save as headerless spreadsheet file...
• Metrics grammar: added *Clash, *Lapse, WeightByPosition and *MoraicConsonant.

Scripting:

• nowarn, noprogress, nocheck.
• Line numbers.
