Using the Attach Sound tool

You use the Attach Sound tool to record a sound note or select an audio file that is played back when the user double-clicks the Sound Note icon. Note that your computer must have a microphone in order to record your own sound notes and add them to your PDF document.
To record a sound note for playback in your PDF document, follow these steps:

1. Click the Attach Sound tool on the Advanced Commenting toolbar pop-up menu.
2. Click the Speaker mouse pointer at the place on the page in the PDF document where you want the Sound Note icon to appear. When you click this pointer, Acrobat opens a Sound Recorder dialog box.
   
3. To record the sound note, click the Record button and speak into your computer’s microphone. When you finish recording, click the Stop button. To play the note before adding it to your document, click the Play button (which replaces the Stop button).
4. Click OK in the Sound Recorder dialog box. The Sound Recorder dialog box closes, and the Sound Attachment Properties dialog box opens.
5. Click the Appearance tab and select an icon for the sound attachment —either Ear, Microphone, or Sound (speaker) in the Icon list box. Click the Color button and select a new color for the sound attachment icon on the color palette that appears. Increase or decrease the opacity of the sound attachment icon by typing in a new percentage number in the Opacity text box or using the slider button.
6. Click the General tab and edit the default text in the Author, Subject, and Description text boxes. Text entered in the Description text box identifies the sound file when you position the mouse pointer over its attached sound icon.
7. Click the Review History tab to view any recent changes to the status of the attached sound during a review cycle. When you’re finished changing Sound Attachment properties, click Close to exit the dialog box.

You can also select a prerecorded sound file to play back when the Sound Attachment is played. To select a prerecorded sound file, click the Browse button in the Sound Recorder dialog box to open the Select Sound File dialog box. Click the folder that contains the desired sound file, click the sound file icon, and then click the Select button.
To play a sound note that you’ve added to a PDF document, double-click its Sound Note icon with the Hand tool or right-click (Control+click on Mac) its icon and then click Play File on the context menu.
