Replace artifacts with ambient sound
Replace artifacts with ambient sound.
Repeat step 2, and select an artifact that doesn’t interact with musical frequencies. (In our example, we selected the second cough, which emphasized upper frequencies above the music.) Hold down Ctrl, drag the selection to an area that contains only ambient sound, and choose Edit > Copy. Again hold down Ctrl, drag the selection back over the artifact, and press Delete. Then choose Edit > Paste.
The Ctrl key lets you move marquee selections horizontally only, ensuring that they stay in the same frequency range. When you delete the contents of these selections, feathering occurs at the top and bottom edges, reflecting a smooth rolloff curve at the highest and lowest frequencies. (Note that if you paste into a marquee selection without first deleting its contents, Adobe Audition combines pasted and existing audio.)
