Edit audio files from Adobe Flash, Premiere Pro, or After Effects
From Adobe Flash Professional,
Adobe Premiere Pro, or After Effects, you can quickly access Soundbooth to edit,
repair, and enhance audio files. While these applications support
many standard audio formats, the most versatile choice is Adobe
Sound (ASND). That format lets you readjust fades and effects, save snapshots
that restore previous edits, and create multitrack mixes.
In Adobe Flash, Premiere Pro, or After Effects, select
an audio or ASND file.
Choose Edit > Edit In Adobe Soundbooth
The file
opens in Soundbooth. When you save your edits in that application, the
file updates automatically in Adobe Flash and video applications.

For more information, search for “Soundbooth”
in Adobe Flash, Premiere Pro, or After Effects Help.
