iPods used to ship with a “Don’t steal music.” sticker across their screens; Apple may want to plaster that warning on the Mac App Store listing for Piezo ($10) from Rogue Amoeba. This app does one thing: it saves audio from any application on your Mac. Safari, Spotify, and FaceTime are just a few of the many examples. If it makes noise, Piezo can record it.
The interface is incredibly simple. Once you choose you source from the drop down menu, simply hit the record button to start and click it again to stop. Done. That’s it. You do have the option of changing the quality and title of the recording, as well as adding comments. If you want to try out the app before you buy it, Rogue Amoeba has a free trial on its website that adds noise after ten minutes of recording per launch.
