The Apogee ONE

I will occasionally write reviews here of products that I’m particularly enthusiastic about, or which I find myself using frequently. The Apogee ONE is just such a product: it’s a very high quality digital audio interface (I just made my high-school English teacher cringe by stringing five adjectives before a noun).
But first: what the heck is a digital audio interface anyway?
Simply put, it’s a device that translates an audio signal (for example, the sound of my voice captured by a microphone) and converts it into a digital signal that can be processed by a computer. Specifically, this little device has an input (actually multiple inputs, though you can only use one at a time) and a USB output that plugs into your computer (specifically, your Macintosh—I don’t believe that Apogee supports Windows PCs). Let’s say you want to record a podcast; you’d plug in the digital audio interface into your computer via its USB port, then plug a microphone into the audio interface, then start your recording program (Garageband or Logic Pro for me) and record something.
