You can import or record audio to just about anything in Adobe Captivate. Right-click a slide object and you'll find you can selectAudio > Import to (or Record to). Right-click a slide and you'll find the exact same menu items. And if you want to import or record background audio, you'll find that you can do so by choosing Audio > Import to (or Record to) Background.
Once you've successfully added audio to the object, slide or background, you can then choose Audio and Edit the attached audio file. However, once edited the imported audio clip will no longer match the original file that you imported.
Ever wondered how you can get the edited audio clip out of your project so it can be used in other applications that accept audio? You'll be happy to learn that you can easily export audio clips. Here's how:
While editing an audio clip, click the Podcast button (located in the lower left of the Edit tab).
From the lower left of the dialog box, select Include MP3 files in export, Include WAVE files in export (or both) and then click theExport button.
