Mixing is blending and adjusting the sounds that comprise audio in a sequence. A sequence can contain many audio clips on one or more audio tracks. Actions you perform when mixing audio can be applied at various levels within a sequence. For example, you can apply one audio level value to a clip and another value to the track that contains the clip. In addition, a track that is actually a nested sequence may already contain volume changes and effects applied to the tracks in the source sequence. Values applied at all of these levels are combined for the final mix.

You can modify an audio clip by applying an effect to the clip or to the track that contains the clip. Consider applying effects in a planned, systematic way to avoid redundant or conflicting settings on the same clip.
