Adding Replay as audio to a Studio presentation

Hello all!

This is my first time reaching out to the community here and I really hope I can find some help.

I was trying to do some audio recordings in Studio, but for whatever reason the recording wouldn't save properly.  So I decided to record the audio in Replay, thinking I could just add it in later.

But when I try to add it in now, the file extension isn't there to pick from to find the files and Replay only publishes in mp4 video format.  I just need the audio!  I am a little frustrated.  I only had limited time with a high-end microphone and it will put my project back to have to redo my recordings.

If anyone can tell me how to get the Replay files into a standard mp3 or wave format so I can add them to my Studio presentation (or whatever other solution is best!), I would really appreciate it!

Thanks so much - Isabelle
