Voice Memo HELP!

Hi,

I accidentally recorded ON TOP of a recording i made earlier at a super important meeting.

I've tried iExplorer, and I find my memo and everything, but of course I can't see my memo BEFORE i recorded on top of it.

Is there a super nerd, who knows what I could do?

I'm on a iPhone 5, iOS 8.3.

Thanks in advance.

Best,

Simon
