Resizing Audio Clips

You control the duration of an audio clip (the amount of time the clip plays back) by resizing the clip. When you add a clip to the Timeline, the clip has the same duration as the source audio file.

You can shorten clips to play back only a part of the source file. When you resize a clip by shortening its left edge, you change the point in the source audio file at which the clip starts playing, making the earlier part of the source audio inaudible. When you resize a clip by shortening its right edge, the part you shorten becomes inaudible. You cannot lengthen the left edge of a clip with non-looping playback mode beyond the beginning of the source audio file.

When you lengthen a regular, non-looping clip beyond its original length, Soundtrack Pro adds blank space at the end of the clip.

When you lengthen a looping clip, it repeats the source file multiple times. The notches at the top and bottom of the clip indicate the end of each repetition of the source audio file.

To resize an audio clip
  1. Place the pointer at either the left or right edge of the audio clip.

    The pointer changes to a Clip Resize pointer.

  2. Click the edge of the clip and drag left or right to resize it.

    Note: Holding down the Command key while trimming or moving a clip toggles the current snapping state.

When you resize a clip, the edge being resized jumps to the nearest Snap To position if snapping is turned on. If you want to resize the clip independently of the Snap To value, change the Snap To value or turn off snapping before you resize the clip. For information about snapping, see Using Snapping.

To resize an audio clip to the boundaries of adjacent clips
  1. Place the pointer at either the left or right edge of the audio clip.

    The pointer changes to a Clip Resize pointer.

  2. Click the edge of the clip.

  3. Hold down the Shift key and drag left or right to resize the clip.

    Resizing clips is limited to the boundaries of adjacent clips.

Using the Trim Command

Soundtrack Pro lets you adjust the In and Out points of clips in the multitrack Timeline using the Trim command. You can either trim the In point of a clip to the playhead or trim the Out point of a clip to the playhead.

Note: If no clips or tracks are selected, using the Trim command applies the trim to all clips under the playhead.

To trim the In point of selected audio clips to the playhead
  1. Set the playhead at the point where you want the clip to begin, then select the clip or clips you want to trim.

    You can trim multiple clips in the same operation.
