In addition, if you've used any of the sound formats listed in the first column in the following table, make sure you distribute the format's corresponding Xtra:

*If you convert an Authorware 3, 3.5, or 3.5.1 file containing audio to Authorware 4, you need to distribute the Authorware 3.x Sound Xtras with the piece.

**Shockwave Audio doesn't work on all Macintosh models. It's limited to Power Macintosh computers.

When you distribute an Authorware piece, create an Xtras folder in the folder that contains either the run-time application (Runa4w or RunA4M) or the Authorware piece you're distributing (if you packaged it with the run-time). Put the Xtras in the Xtras folder.
