How to recover audio recording? in Evernote for iOS Issues (Versions 8.24.6 and under) Posted November 30, 2013 I use Disk Aid. I did a voice recording with it just to see. In the folder that you see the inbox and your email, you should also see a file with the extension .m4a. That file appeared after I did the recording. I'm thinking if the recording is somewhere it isn't within evernote.
