Cross-fade is used whenever you need to loop part of a sample, so it seamlessly repeats, with no audio "gaps" or unwanted artifacts. This is particularly useful when you have, say, sampled a synthesizer, and want to loop part of the sample while the note is sustained.
In the wave editor, select part of the sample you wish to loop (typically, after the initial attack, and before the release). The cross-fade processing will take an amount of sound, just before the loop start, and mix it with the loop tail.
For example, with a 500ms cross-fade, 500ms of audio before loop start will be faded-in with the last 500ms of the loop tail, where this portion will be faded-out.
That's why you can't cross-fade directly from the start of the sample, as you need some audio samples to mix with the loop tail.
The higher you set the cross-fade time, the smoother the transition will be.
You can create very unique sounds, drones, background loops, and of course it's useful for looping sampled instruments (synth, keys, etc.).

Cross-fade is destructive (meaning it modifies the samples in the audio file), so make sure you 'save as' to keep your original file intact !
