To download the latest version of the MacOS edition of Praat, click once on the following disk image file:
After downloading, your web browser might open the .dmg file directly; you will then see the program Praat or Praat.app. If your browser did not open the .dmg file, then you should double-click the .dmg file in the Downloads window (or in the Downloads folder in your home directory); after double-clicking you may see the program Praat or Praat.app directly, or you may see a disk icon called Praat6405, which when you open it will show you the program Praat or Praat.app. To install Praat, just drag the program Praat or Praat.app to your Applications folder (or anywhere else).
To start up the Praat program, just double-click it. If you use Praat for the first time, choose Intro from the Help menu.
If you have trouble starting Praat for the first time:
To protect you against harmful software, MacOS enforces increasingly severe security measures, initially trusting only apps that you downloaded from the App Store. This is a good thing, but it does make it increasingly difficult to start up reliable applications that you download from outside the App Store, such as Praat. Your Mac can throw a variety of messages at you:
If you want to see good-quality phonetic characters on your screen and in your clipboard, you have to install the Charis SIL and/or the Doulos SIL font. These fonts were created by the Summer Institute of Linguistics. To install them, first download the archives:
Then unpack the .zip files, if your web browser has not already done that. This will give you folders called CharisSIL-6.200 and DoulosSIL-6.200. When you open these folders, you will see TrueType fonts such as CharisSIL-Regular.ttf, CharisSIL-Bold.ttf, CharisSIL-Italic.ttf, and CharisSIL-BoldItalic.ttf, and DoulosSIL-Regular.ttf. For each of these five fonts, double-click it, wait for the Font Book window to appear, and then click Install Font.
Recording. If your recorded sound is all zeroes, then you may have disallowed Praat to access the microphone; in that case, go to System Preferences -> Security & Privacy -> Microphone and put a check mark next to the Praat symbol.
Playing on macOS 11 BigSur or macOS 12 Monterey. If there is a click or crack at the end of a sound, go to Praat -> Preferences -> Sound playing preferences, and set Silence After to 0.5 seconds or so.
Playing on macOS 10.14 or 10.15. It is possible that your sounds play terribly, with cracks, repetitions and pauses. A likely cause is a macOS bug that you can solve: open Audio MIDI Setup (in Applications -> Utilities), go to MacBook internal loudspeakers (or so) -> Output, change the Format from 48000 Hz to 44100 Hz, and play a sound again in Praat, which should now sound correctly. Even though your Mac will change this setting back to 48000 Hz, sound output is likely to continue to sound correctly.
Sounds are recorded into a buffer whose size you can set with “Sound recording preferences”.
The best way to produce pictures is to use the clipboard or “Save as PDF file...” in the Picture window. Both the clipboard and “Save as PDF file...” produce PDF pictures. Most word-processing programs newer than 2006 accept such PDF pictures, at least on the Mac; if you use Microsoft Word 2008 or later, make sure to save your document as a .docx file, because if you save it as a .doc file, Word will convert the inserted PDF pictures into mediocre bitmaps.
To run Praat from a terminal window, write a Praat script and specify that script on the command line, optionally with arguments, e.g.:
/Applications/Praat.app/Contents/MacOS/Praat --run playsinewave.praat 377 0.9
For details see Calling from the command line in the Scripting manual.
On a modern computer you would use Praat 6.4.05, as suggested above. If that does not work on your computer, you can probably try an older version:
