A Eulogy for the Headphone Jack

Medium, technology, progress, IO, headphones, apple, engineering, 2018, DRM

To any headphone jack, all audio is raw in the sense that it exists as a series of voltages that ultimately began as measurements by some tool, like a microphone or an electric guitar pickup or an EKG. There is no encryption or rights management, no special encoding or secret keys. It’s just data in the shape of the sound itself, as a record of voltages over time. When you play back a sound file, you feed that record of voltages to your headphone jack. It applies those voltages to, say, the coil in your speaker, which then pushes or pulls against a permanent magnet to move the air in the same way it originally moved the microphone whenever the sound was recorded.

Smartphone manufacturers are broadly eliminating headphone jacks going forward, replacing them with wireless headphones or BlueTooth. We’re going to all lose touch with something, and to me it feels like something important.

The series of voltages a headphone jack creates is immediately understandable and usable with the most basic tools. If you coil up some copper, and put a magnet in the middle, and then hook each side of the coil up to your phone’s headphone jack, it would make sounds. They would not be pleasant or loud, but they would be tangible and human-scale and understandable. It’s a part of your phone that can read and produce electrical vibrations.

In our campaigning on this issue, we have spoken to many, many members’ representatives who privately confided their belief that the EME was a terrible idea (generally they used stronger language) and their sincere desire that their employer wasn’t on the wrong side of this issue. This is unsurprising. You have to search long and hard to find an independent technologist who believes that DRM is possible, let alone a good idea. Yet, somewhere along the way, the business values of those outside the web got important enough, and the values of technologists who built it got disposable enough, that even the wise elders who make our standards voted for something they know to be a fool’s errand.

We believe they will regret that choice. Today, the W3C bequeaths a legally unauditable attack-surface to browsers used by billions of people. They give media companies the power to sue or intimidate away those who might re-purpose video for people with disabilities. They side against the archivists who are scrambling to preserve the public record of our era. The W3C process has been abused by companies that made their fortunes by upsetting the established order, and now, thanks to EME, they’ll be able to ensure no one ever subjects them to the same innovative pressures.
