+correct content-type this time ;) Note this has already been merged, but still worth mention for visibility.

We are about to merge in support for audio derivatives to Timed Media Handler (TMH). The big value here, I think is encoding to AAC or MP3 and adding a /listen to this article/ feature to the mobile app. https://gerrit.wikimedia.org/r/#/c/39363/

This can really help with improving accessibility of Wiktionary pronunciation media files as well.

Also AAC / m4v ingestion, could make audio recordings a lot easier to import into the site, i.e a "record a reading of this article" mobile app feature #2 ;)

There are already thousands of spoken articles, with some promotion their could probably be a lot be more: http://en.wikipedia.org/wiki/Category:Spoken_articles

The software patent situation for mp3 is sad, considering how long the mp3 format has been around: http://www.tunequest.org/a-big-list-of-mp3-patents/20070226/

I think AAC is a similar situation, encoder wise: http://en.wikipedia.org/wiki/Advanced_Audio_Coding#Licensing_and_patents

But fundamentally Wikimedia is not "distributing" these encoders and there are no royalties for media distribution. Likewise we are not shipping decoders ( the decoders are in browser or the mobile OS )

I don't know why Wikimedia's commitment to being accessible in royalty free formats, somehow also precludes making content accessible for folks on platforms that ~don't~ decode royalty free formats. But hopefully we can change that over time.

Not sure if this is the right forum for this, but I hope we could come out of this thread with rough consensus to enable these formats to help increase the reach of audio works.
