On any AUDIO clip click the FX button, to open the effects editor.
Click the green + sign on the toolbar and choose AMPLIFY.
Click in the preset field and choose FADE IN and OUT.
Drag the blue line to create a plot similar to what is seen below. Each time the line is dragged it creates another keyframe (dot). To delete a keyframe, right-click on it.
Once you are satisfied, click the button just to the right of the green + on the toolbar: SAVE AS EFFECT CHAIN TEMPLATE. Name it. That template will appear at the bottom of the audio effects window. It is a custom audio template.
To apply the effect to a single clip, open the audio effects window and click on that template.
To apply it to multiple clips, select (highlight) the desired clips, then click AUDIO EFFECTS on the VP toolbar and choose the FADE IN and OUT template. You will be prompted to apply to all selected clips or just one.
