You can extract audio from clips and generate
new audio master clips in a project. The original master clips are
preserved. Any source channel mappings, gain, speed, duration, and
interpret footage adjustments in the original master clips are applied
to the new, extracted audio clips.
In the Project panel, select one or more clips
containing audio.
Choose Clip > Audio Options >
Extract Audio.
Adobe Premiere Pro generates new audio files containing
the extracted audio, with the word “Extracted” added to the end
of the filenames.
