Crashes when creating a new audio recording

Really promising app, unfortunately it crashes when you try to create a new audio recording from the menu. A fix would be greatly appreciated for a $9 app!

Developer Response ,

Thank you for reporting it and I am sorry for encountering this. This issue is fixed in version 1.5.

Can’t open pre-recorded files

Wasn’t clear from the description (since it said "import from any source") but the app won’t import a pre-recorded file. There is no help file, nor documentation. Tried .wav, mp3, and m4p without luck.
