How to Edit Sounds Adobe Flash CS6
Adobe Flash CS6 provides a useful way to do basic editing on placed sounds using the Edit Envelope dialog box. The Edit Envelope dialog box performs basic trims and volume effects and lets you adjust volume and pan settings for each sound placed in your movie.
Although nothing quite replaces well-recorded and edited source files, you can do last-minute, nondestructive edits so that your sounds complement the rest of your movie.
To edit a sound, select a keyframe that has a sound placed on it or add a sound to a new keyframe and then follow these steps:
Select the keyframe on which the sound is placed.
In the Property inspector, locate and click the Edit Sound Envelope button (the pencil icon to the right of the Effect drop-down list) in the Sound section.
The Edit Envelope dialog box appears with a waveform preview. The center time ruler has two sliders on the far left and far right.
Move these sliders to edit the in and out points of the sound or to trim unnecessary silence.
The lines above each waveform represent the volume envelope.
Click the lines above each waveform and drag them up or down to adjust the overall volume of the sound or to add handles and vary the volume at different points during the sound.
The higher the line or handle, the louder the sound.
Use the Effect drop-down list in the upper-left corner to choose from several preset volume and pan effects to enhance your sound.
When you’re done, click OK and then press Enter or Return to play your movie and hear the changes made to the sound.
