Is there a Mac app that can be set to always record audio and only keep the last five to ten minutes (everything older than that would constantly be erased)? I'd like an app like this so I can speak my thoughts out loud and if I have a senior moment then I can go back and find the lost thought. It doesn't have to be an app, an Audio Unit would be fine as well. This sort of memory loss usually only happens to me when I get a bunch of ideas at once; I forget some before I finish writing (or typing) them all down.
