To download the latest version of the MacOS X edition of Praat, click once on one of the following disk image files:
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 Praat5403, 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).
Any Mac operating system since Lion (10.7) fully supports 64-bit applications. Praat's 64-bit edition is therefore preferred, because it can work with larger sound files than the 32-bit edition, and can have more than 2 GB in its memory; also, the 64-bit edition supports some newer interface features, such as that you can scroll by swiping over your trackpad, or zoom by pinching on your trackpad. If you have Mac OS X 10.5 or 10.6, you have to install the 32-bit edition instead.
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 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 CharisSIL4 and DoulosSIL4. When you open these folders, you will see TrueType fonts such as CharisSILR.ttf, CharisSILB.ttf, CharisSILI.ttf, CharisSILBI.ttf, and DoulosSILR.ttf. Drag these five fonts to the /Library/Fonts folder in the top folder on your hard disk, if you have write access to that folder. Alternatively, you could put the fonts in the Library/Fonts folder in your home folder, although other users of your computer cannot use them in that case.
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.
