A Linear Fade, the most simple type of fade, is used in converters, where the level or amplitude of the signal rises or falls at the constant rate.

An important parameter is the "Fade In" and "Fade Out" time. Most appropriate "Fade In" or "Fade Out" time can be around 0.5s. This value is selected in "Preferences / Effects" by default, and can always be adjusted.
