About audio channels and audio components
Audio files can contain a single audio channel or multiple audio channels. Channels usually
correspond to microphone inputs during recording or to speakers for multichannel output. For
example, a stereo audio file usually contains left and right channels that match what you hear
from the left and right speakers during playback.
Final Cut Pro automatically groups channels into audio components according to how the
channels are configured for the clip. You can expand the audio portion of clips to view and edit
audio components down to the individual channel level. You can then make separate volume
or pan adjustments or apply and keyframe different audio effects for each component. For more
information, see
on page 168.
The number of audio components you see corresponds to the number of channels you’ve
configured in your source clip.
Note: Many popular digital audio file formats, such as AAC and MP3, use interleaved stereo files,
which do not contain separate left and right channels. A stereo clip with interleaved left and
right channels appears as a single audio component in the Audio inspector and the Timeline. If
you change the clip’s channel configuration from Stereo to Dual Mono, the channels appear as
two separate audio components.

Ways to view audio clips
When you work with audio waveforms in the Timeline, you can zoom in or out or change the clip
appearance to make the waveform taller or shorter.
Final Cut Pro also includes several ways of viewing and working with audio and video within
clips. You can:
•
Expand a clip to view and edit audio components down to the individual channel level.
•
Expand a clip to see separate audio and video.
•
Detach audio from a video clip to work on the audio and video as separate clips.
•
Change the background appearance of a clip to show reference waveforms, which make it
easier to see audio waveforms when the volume is diminished.
