Working in the Timeline

When you change the offset of a clip, the waveform moves inside the clip’s boundary to
indicate the change in offset. The length of the clip stays the same. If the clip has not
been resized, it will reach the end of the source audio file and start looping. As you
move the offset by dragging, the clip’s notches move to show the point at which the
clip will start looping.
Changing a Clip’s Playback Mode
Audio files you add to the Timeline can be either looping or non-looping. Looping files
are special audio files that can be used to create repeating patterns, and include
musical phrases useful for creating music beds. Audio files containing discrete, non-
rhythmic sounds, sound effects, and other non-musical sounds such as dialogue or
sound effects should be used as non-looping files in most cases.
When you add an audio file to the Timeline, the audio file is added as a clip with non-
looping playback mode unless the audio file is tagged as a looping file. You can change
the playback mode of a clip after you add it to the Timeline.
To convert the playback mode to looping, do one of the following:
m
Select the clip, then choose Clip > Convert to Looping.
m
Control-click the clip in the Timeline, then choose Convert to Looping from the
shortcut menu.
To convert the playback mode to non-looping, do one of the following:
m
Select the clip, then choose Clip > Convert to Non-Looping.
m
Control-click the clip in the Timeline, then choose Convert to Non-looping from the
shortcut menu.
Replacing the Source Audio in a Clip
Each audio clip in the Timeline has a set of properties specific to the clip, including
duration, speed, and transposition. You can replace the source audio in the clip while
preserving the clip’s properties. This feature has a variety of uses, such as letting you try
out similar audio files (for example, music beds or sound effects) while maintaining the
clip’s duration, position in the Timeline, and transposition.
