WireTap Pro is a so so app. My main problem with it is they are sooooo slow on updates. If a quicktime update comes out and breaks it, expect to wait for a while till they come up with an update so you can use it again. It also records (at least it did up until I stopped using it) your system sounds as well. So if your mail makes a ding sound for example, it will come out on your recording. It is also more expensive than audio hijack which is far superior.

Not a terribly bad program, there is just better out there. Plus, as you read here and in other posts they drag their feet terribly with updates.
