Using The Sound-Editing Controls - MACROMEDIA FLASH 8-USING FLASH Use Manual

Flash Player 6 (6.0.40.0) and later supports MP3 files with ID3 v1.0 and v1.1 tags. With ID3
v1.0 and v1.1 tags, the properties are available at the end of the data stream. If a sound does
not contain an ID3v1 tag, the ID3 properties are undefined. Users must have Flash Player 6
(6.0.40.0) or later for the ID3 properties to function.
For more information on using the ID3 properties, see
ActionScript 2.0 Language Reference.

Using the sound-editing controls

To define the starting point of a sound or to control the volume of the sound as it plays, you
use the sound-editing controls in the Property inspector.
Flash can change the point at which a sound starts and stops playing. This is useful for
making sound files smaller by removing unused sections.
To edit a sound file:
1.
Add a sound to a frame (for more information, see
on page 313), or select a frame that already contains a sound.
2.
Select Window > Properties.
3.
Click the Edit button on the right side of the Property inspector.
4.
Do any of the following:
To change the start and end points of a sound, drag the Time In and Time Out
controls in the Edit Envelope.
To change the sound envelope, drag the envelope handles to change levels at different
points in the sound. Envelope lines show the volume of the sound as it plays. To create
additional envelope handles (up to eight total), click the envelope lines. To remove an
envelope handle, drag it out of the window.
To display more or less of the sound in the window, click the Zoom In or Out buttons.
To switch the time units between seconds and frames, click the Seconds and
Frames buttons.
5. To hear the edited sound, click the Play button.
