YouTube user canzona uploaded a video to the web, downloaded it, then re-uploaded it one thousand times, gradually eliminating "all human qualities" of his voice and image.

The final video in canzona's series is a mess of distorted colors and sounds; you can recognize from the motion that the original featured a person talking into the camera, but all individual characters and specifics have been lost, replaced by artifacts created by YouTube's video and audio compression algorithms.

All 1,000 steps of the process — which took a full year — are available on canzona's YouTube profile. The project is titled "I Am Sitting in a Video Room," and it's inspired by an audio art project recorded by composer Alvin Lucier more than 40 years ago.

The first, 100th, 250th, 500th and 1,000th steps are embedded below.

Why Did This Happen?

Each time you upload a video to YouTube, that video is compressed by YouTube's servers so the file size becomes small enough to easily stream to web viewers.

Image compression is achieved by recording only changes from one frame to another rather than all of the data in each frame, removing small differences in color that the human eye usually can't detect while an image is in motion, and through other small modifications to the image. The idea is that these small changes will not result in any dramatic loss in quality to the untrained eye.

However, when you compress the same thing 1,000 times over, it's like the old adage about making a copy of a copy — the changes pile on top of one another and the image is so corrupted that it becomes unrecognizable. The same goes for audio compression.

The Inspiration: Alvin Lucier's "I Am Sitting in a Room"

In 1969, avant garde composer Alvin Lucier made an audio recording of a brief speech, then played the speech on the speakers and recorded that playback. He repeated this until the acoustics of the room caused some frequencies to overwhelm others more with each recording. The result was a recording that sounded more like a message from another dimension than a man's voice.

Lucier's work often focused on the natural, physical properties of sound instead of musical theory. YouTube's canzona was inspired by Lucier's work to create "I Am Sitting in a Video Room" — even the words that he speaks are similar to those in Lucier's original work.

There have been other digital projects inspired by "I Am Sitting in a Room." Arguably the best known is Residuum's entirely synthesized variation; he uses a computer voice synthesizer and applies a digital filter that emulates the echoes of a real room. By the 57th iteration, a crystal clear resonance sound replaces the original phrasing.
