Beat Sync of Live Recordings

Hello there!

I am relatively new to Audition. I would like to make a beat that was recorded in a live preformance fit the beat grid exactly. As there was no metronome or so, the music is getting slightly faster over time. But as I want to mix it with other songs, I need it to fit the beatgrid perfectly.

So what I am looking for is something like Logic Pro's Flex Time tool. Does Audition have a feature like this?

Thanks in advance!

Felix
