When you replace the source audio in a clip, the clip’s duration and offset stay the same.
Only the portion of the new source audio file equal to the clip’s length plays. If the new
source audio file is a music loop and it is shorter than the clip’s length, the clip loops
when it reaches the end of the new source audio file. Notches appear on the clip to
indicate the point at which the clip starts looping.
You can replace the source audio in all clips using the same source audio file with another
source audio file by using the Select All Occurrences and Replace Selected Loops
commands together.
