USING ADOBE PREMIERE PRO 217 Editing Audio More Help topics "Review project settings" on page 52 "Work with submixes" on page 245 "Work with tracks" on page 138 Channels in audio clips Clips can contain one audio channel (mono), two audio channels-left and right (stereo), or 5 audio surround channels with a low-frequency effects audio channel (5.1 surround). Although a sequence can accommodate any combination of clips, all the audio is mixed to the track format (mono, stereo, or 5.1 surround) of the master track. Premiere Pro lets you change the track format (the grouping of audio channels) in an audio clip. For example, sometimes you may want to apply audio effects differently to the individual channels in a stereo or 5.1 surround clip. You can change the track format in stereo or 5.1 surround clips so that the audio is placed on separate mono tracks when the clips are added to a sequence. Note: You can change a master clip's track format only before you add an instance of the clip to a sequence. Premiere Pro also lets you remap the output channels or tracks for a clip's audio channels. For example, you can remap the left channel audio in a stereo clip so that it's output to the right channel.

Sequence audio tracks can contain many audio clips, and the audio tracks of video clips. 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 contains the audio for 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. Chris and Trish Meyer provide an overview on the Artbeats website of how to mix and time multiple audio tracks for maximum clarity and story-telling impact.
