About TapeDeck
Audio recorder exclusively for Mac OS X 10.5+, designed with a quick-capture workflow in mind. You’re never more than a single mouse click (or keystroke) away from making a new recording, which are called, unsurprisingly, “tapes.” TapeDeck records directly to compressed MP4-AAC audio, making it equally useful for quick high-fidelity samples or hours and hours of lecture.

As you can see, TapeDeck was designed to emulate a real cassette tape recorder (perhaps you have a similar model in your basement), but with a few key differences:

- Every recording you ever make is immediately saved in the box of Tapes.
- You cannot record over an existing tape; clicking Record automatically starts a new tape for you.
- Many more features.
