Adding Audio files to MediaShout requires that the audio file be in a format that's stored on your local hard drive. We generally recommend MP3 format, since this is the universal de-facto standard in audio file storage. If you have a CD, you'll need to rip the CD to your hard drive. Many audio programs, including iTunes (instructions for iTunes) and Windows Media Player (instructions for Windows Media Player) offer this ability as a free feature.
Once the file is ripped to your hard drive, all you need to do is add the audio file via the Soundtrack tab. Once on the Soundtrack tab (#1), make sure Cue (#2) is selected and then browse for your file (#3). Please see the picture for clarification.
