This command fades audio, i.e. smoothly gradates its volume from one level to another. If a selection exists, only the selection is faded, otherwise the entire document is faded. The command displays the Fade dialog, which lets you specify the type of fade:
| In | Fade from silence to full volume. |
| Out | Fade from full volume to silence. |
| Custom | Fade from one arbitrary level to another: in this case the starting and ending levels must be specified, in decibels. |
To make the fade logarithmic instead of linear, check the Logarithmic checkbox. To do the fade, click OK or press Enter.
