Wikimedia: The world’s most popular audio file format arrives at Wikimedia

Wikimedia: The world’s most popular audio file format arrives at Wikimedia . “Until this month, no Wikimedia site supported the world’s most popular audio file format, MP3, because the technology for encoding and decoding these files was encumbered by restrictive patents.
With the expiry of these patents, however, we are now supporting MP3 uploads for trusted users on Wikimedia Commons—a free media repository that hosts the majority of the images, videos, and audio recordings for Wikipedia and other Wikimedia projects.”
