# Fading the Sound In and Out

You can modify the volume throughout a sound clip by adjusting the fade-in and fade-out times; these are also known as envelopes.When you play the sound clip the volume adjusts over time to fade the sound. The fades only affect the playback; the original sound file is not affected.

To adjust the fade in/out effect on a sound clip:

1. Select the Sound element and select Element > Edit Sound. The Sound Element Editor dialog box opens.

2. In the Sound Element panel, select the sound you want to work on. A more detailed version of the selected sound appears in the Current Sound panel.

3. In the Current Sound panel, click the waveform to add an envelope marker.

4. Drag the envelope markers to adjust the volume at each frame and the time of the transition.The line from the edge of the clip to the envelope marker identifies how the volume either increases (fades-in) or decreases (fades-out) over time.

| You can also adjust the volume (mix) sound in the Sound Element Editor. In the Sound Element panel, select the sound whose volume you want to adjust. In the Current Sound panel, drag the volume slider to the new level.
