Accidentally closing saving recording window

[Jezza]

I have a class where I need to record ourselves doing a long discussion - it was 70 minutes long. I was responsible for recording it, but when class ended, I forgot i was saving the file and accidentally pressed Command + Q. Usually when things need to be saved, a window would pop up and ask something like "Would you like to finish saving before quitting?" or something like that, but this time it didn't for some reason - other apps would do this like Word Doc, etc. It didn't mention anything, but now I cannot seem to find my recording anywhere. Is there any way to recover the recording?? PLEASE HELP!!!
