What a Wonderful Piece of Work is Opus

When we talk of free software, we typically think of things like GNU/Linux, Apache or Firefox. But one aspect that often gets overlooked is that of multimedia codecs.

The haiku is copyright 2007 by Edward W. Felten:

We own integers,
Says AACS LA.
You can own one too.

Here is your very own 128-bit integer, which we hereby deed to you:
