On the View menu, point to Enhancements, and then
click Crossfading and Auto Volume Leveling.
In the Enhancements pane, click the Turn on Crossfading
link, if visible.
Move the slider to select the amount of time that you want the
items to overlap.
Note
During playback, the audio crossfade feature
gradually overlaps the end of the current item (such as a song)
with the beginning of the next item. The result is a smooth audio
transition from one item to the next as the first item fades down
and the next item fades up. The effect is similar to how songs on
the radio are typically played.
To hide the crossfading and auto volume leveling
settings, in the Enhancements pane, click the Close
button.
