Fade
The Fade effect includes two components: Fade In and Fade Out. Use the Fade In effect to fade in the sound in the media file. If you select a part of the file with the mouse, this effect will fade in the sound of this exact part of the file. Otherwise the sound of the beginning of the file will be faded in. Use the Fade Out effect to fade out the sound in the media file. If you select a part of the file with the mouse, this effect will fade out the sound of this exact part of the file. Otherwise the sound of the end of the file will be faded out.
In the Properties Window you can change the effect properties. It's possible to select the necessary preset from the dropdown list or set custom values for Amplify Start and Amplify End.
