# Trimming the Start and End of a Sound File

If you want to play only a section of a sound file, you can use the Sound Element Editor dialog box to select the exact part you want to use.

For example, let’s say there is a bit of noise at the start of the sound. You can use the Sound Element Editor to cut the noise at the start of the sound file.

The Sound Element Editor does not change the original sound file; it only plays a section of it, ignoring the rest. This allows you to reuse the full sound in other scenes in the movie. However, this means that the entire sound file is included on export. So if must be considerate of file size, it is better to edit sound files completely in a sound editor before you bring them into Toon Boom Studio.

Toon Boom Studio does not change the sound to fit into the number of frames you select. If the number of frames you select is longer than the played sound, no sound is heard from that point on.

To select the section of a sound file to play in your scene:

1. Select the Sound element and select Element > Edit Sound. The Sound Element Editor dialog box opens.

2. Select the sound you want to work on from the Sound Element panel.

To distinguish one sound file from another, check the frame numbers that appear above the sound waves or select a sound wave and click the Play button in the Current Sound panel (only the select sound will play).

3. Using the Current Sound panel, you can decide which part of the file you want to play by dragging the left and right boundaries of the selection area.
