To create an audio optimization definition file

1. Use a text editor, such as Notepad to create a text file.
2. Type the version number and the number of music segments the file contains.

   The version number should always be the number 1.

3. Type the start and end times (in milliseconds) of each segment, and separate each start and end time with a comma.

   For example, typing 1, 3, 0, 10000, 50000, 80000, 150000, and 200000 indicates that there are three music segments; the codec will switch to music mode at 0 to 10 seconds, 50 to 80 seconds, and 150 to 200 seconds.

4. Encode the text file in Unicode.

   If you use Notepad to create the file, you can save the file as Unicode by choosing the Save As command on the File menu, and then, in Encoding, clicking Unicode.
