Remix feature not working for audio clip
Hi all,
In Adobe Audition is have this audio clip I want to remix (so I can extend its duration), only it's not working. Constantly when I press the "Remix" button it says "Analysis failed". I tried to remix just a normal song I had and this worked fine. It seems like all the time when I want to remix this small 2 seconds clip it's not able to remix it.
The screenshot attached shows the Analysis failed.
How can I solve this so I can extend my audio clip?
Mike.
