While it adds a step, this approach lets you choose the export format, filename, and location for the replacement audio.
You can also isolate the audio you want to work on in Audition using the Work Area bar (soloing the tracks you want to keep, or muting any unwanted tracks) and then export it from Premiere Pro as an uncompressed audio file so it can be imported into Audition.
The alternative routeīut if you prefer a more controlled, manual approach (I do), there is another way. Just right-click on the extracted file in the Premiere Pro sequence and choose Restore Unrendered. Tip: It’s also worth noting that the clip’s original audio can easily be restored if things go south and you need to backtrack. So just make sure that your current installation hasn’t inherited a previous version’s behavior by selecting the Next to original media files option. But Premiere Pro used to save the copy in a scratch disk location instead, which tended to break things if you moved the original project to a new location and left the extracted file behind. These days, the default behavior is to save the extracted file alongside the original file. Make sure you know where the rendered files are being saved.
