From Audacity Development Manual
Crossfade Clips applies a simple crossfade to a selected pair of clips in a single audio track.

  Accessed by: Effect > Crossfade Clips

  There are no parameters to set for this effect; the effect operates on the audio that is currently selected.

  If the crossfade takes an appreciable time, a progress dialog will appear as below:

## Instructions

1. Place two audio clips into the same track.
2. Select (approximately) the same amount of audio from the end of one clip and the start of the other.
3. Apply the effect.
4. The selected regions will be crossfaded.

Note, the audio clips do not need to be touching. Any white-space between the clips is ignored.

If the selected region is continuous audio with no splits, the first half and last half of the selected audio will be crossfaded.

Advanced Tip: A discontinuity in a waveform, such as a large click, may be smoothed by applying a short crossfade across the glitch.

## Limitations

These should not occur in normal usage:

- There may be no more than two clips selected in each channel.
- The selection may not start or end in white-space.

## Examples

Example of using the effect for a simple crossfade

1) Place your audio clips end to end in a track.

2) Zoom in a bit.

3) Select the part that you want to crossfade (does not matter if the tracks are right up against each other or not - just select the parts to crossfade).

4) Select the Effect > Crossfade Clips.

5) Simple crossfade completed

Example of using the effect to repair a glitch

You can use Crossfade Clips to fix glitches when there are no convenient zero crossing points for making a clean edit. 1) Audio surrounding the glitch is selected

2) Using Effect > Crossfade Clips repairs the glitch.
