# Working With Sound Sequences

The sound features in Toon Boom Storyboard make it possible for you to edit sounds that you imported. If you want to play only a section of a sound sequence, you can select the exact part you want to use. You can adjust volume levels of sound sequences to fade in, fade out, or mute sounds, without affecting the original sound sequence.

You must work in the Timeline Workspace.

To customize the sound track features:

- To show the waveform of the sound sequences, select Sound > Show Waveform.

- Once waveform is displayed, you can also select Sound > Show Volume to display the playback sound level for each sound sequence.
- Select Sound > Sound Scrubbing to listen to the sound as you drag the red Current Frame slider forward and backward.

You can edit sounds that were created outside of Toon Boom Storyboard, then imported into the project.

To edit a sound sequence:

1. Verify that the volume is on for the view and the sound track you want to work with.

You may find it easier to edit the sound by customizing the display to show the sound’s waveform.

You can listen to the sound by dragging the Current Frame slider across the sequence to scrub the sound.

2. Do one of the following.

- Drag the cursor that appears at the start frame to the position where you want to set the new start of the clip. This will cut the beginning of the original file from playback.
- Drag the cursor that appears at the end frame to the position where you want to the clip to begin. This will cut the end of the original file from playback.

You can play back the sound to hear the edited version of the sequence. The original sound sequence is not modified. You can drag the boundaries of the edited sequence closer to or all the way back to their original positions to use more of the sound sequence.

To split a sound sequence in two:

1. Move the red Current Frame slider to the frame where you want to begin the second sound sequence that results from the split.

2. Select Sound > Split Sequence at Current Frame.

You can change the volume throughout a sound sequence by specifying new volume levels and adjusting the rate at which sound fades in and out. The original sound sequence is not affected, but you will hear the sound with the edited levels, when previewing a storyboard or playing its output as an animatic.

To display and adjust the volume levels of a sound sequence:

1. Select Sound > Show Waveform.

2. Select Sound > Show Volume.

A blue line, indicating the sound level, is displayed for each sound sequence. White squares mark the points at which the sound changes to a new level.

3. Click the line to add a new marker, or drag an existing marker to adjust the volume at a specific frame.

The slope of the line indicates how quickly the sound changes from one level to another. If the slope is steep, the change is abrupt. If the slope is less inclined, the volume changes at a more gradual rate.
