turer. For information on using your specific DDR with After Effects, refer to your DDR manufacturer's plug-in
documentation.
Edit audio in Adobe Soundbooth or Adobe Audition
While working in After Effects, you may want to use the more comprehensive audio-editing capabilities of Adobe
Soundbooth or Adobe Audition to fine-tune your audio layers. You can use the Edit In Adobe Soundbooth or Edit
In Adobe Audition command to start Adobe Soundbooth or Adobe Audition from within After Effects.
If you edit an audio-only file (for example, a WAV file) in Adobe Soundbooth or Adobe Audition, you make changes
to the original file. If you edit a layer that contains both audio and video (for example, an AVI file), you edit a copy
of the layer's audio file.
Important: Adobe Soundbooth is only available for Windows and for Mac OS running on Intel processors. Adobe
Audition is only available for Windows. Neither Adobe Soundbooth nor Adobe Audition are available for Mac OS
running on PowerPC processors.
