Before adding audio segments, you must first create them. Use any sampling hardware and software you choose. Viewer requires audio files to be in Windows audio (.WAV) format. If your files are in a different format, use the Microsoft Convert program (described in the Data Preparation Tools User's Guide) to convert them into .WAV format.
Each audio segment you create is contained in a separate file. Usually, you'll create a subdirectory of the project directory to hold the audio files for your title. For example, all of the .WAV files for the USA Tour sample application can be found in the \VIEWER\USA\SOUNDS directory.
