Adobe Audition lets you use advanced techniques to edit
audio. If you have installed Adobe Audition, you can apply the Edit
In Adobe Audition command to a clip containing audio.
When you apply the Edit In Audition command to an audio clip,
the audio is extracted and the edits are made to a new clip containing
the extracted audio. The audio in the original master video clip
is preserved.
When applying the Edit In Audition command to clips in a sequence,
Premiere Pro renders the audio into a new audio clip that is imported
into Adobe Audition. If an In/Out range was marked in Premiere Pro,
these markers become visible in Audition. When saved the clip is
saved in Audition, the edited clip replaces the original clip in
the Premiere Pro Timeline panel. The original master clip in the Project
panel is untouched. Effects or markers applied to the original sequence clip
are preserved in the edited clip.
You can edit the audio in Adobe Audition many times. For each
subsequent edit in Adobe Audition, Premiere Pro sends the audio
clip that it created for the initial editing session.
From the Project panel, the Undo command deletes the extracted
audio clip that’s been edited in Adobe Audition. For a clip in a
sequence, the Undo command reverses the render and replace actions
by returning the original audio clip to the sequence. In this case,
the newly created audio file is not deleted from the Project panel.
Note: The Edit In Audition command is not available for Adobe Dynamic
Link clips.
