Now, to the main topic at hand: your computer's USB audio port, which can connect to external audio devices that play music from any Web site, file, music service, or app. Luckily for us, it doesn't care whether your output is analog (the regular kind) or digital (USB). Happily for music fans, that vision was never realized, meaning that USB Audio devices-a standard compatible with Mac, Windows, and Linux-can play music from any source normally handled by your regular analog output-the one most people connect to headphones or speakers.Ĭonnected devices have largely obviated the need for onerous DRM technologies in the first place by letting listeners prove they have the right to listen to a piece of music simply by signing in to an app or Web site.

One solution that was bandied around back then: to create a Secure Audio Path (SAP) all the way from the playback software to our speakers, protecting then whole chain with digital rights management (DRM). The person who recorded the song can then share it via P2P with millions of music fans who would never bother connecting an analog recording device to a computer's output and hijacking the audio that way.
The analog hole can allow someone to record otherwise "protected" audio on its way to speakers. The fear driving this shift, which did not happen: the so-called "analog hole."
Once upon a time, there was this scary idea that computer manufacturers would lock down our machines with a purely-digital, "protected," end-to-end music delivery system.
