Well, I guess this should be researched quite well, before investing time in this feature: WAV WAVEform audio format <http://en.wikipedia.org/wiki/WAV> (WAV) is a Microsoft <http://en.wikipedia.org/wiki/Microsoft> and IBM<http://en.wikipedia.org/wiki/IBM> audio file format <http://en.wikipedia.org/wiki/Audio_format> for storing audio on PCs. It is the main format used on Microsoft Windows<http://en.wikipedia.org/wiki/Microsoft_Windows>systems for raw audio storage. The WAV format is most commonly used with an uncompressed, lossless storage method (pulse-code modulation) resulting in comparatively large audio files. Today, the WAV audio format is no longer popular being superseded by other more efficient means of audio storage.

The legal status is not so obvious. Maybe you even need a lawyer to judge this correctly. Again, is .wav really so popular, that it justifies the effort?

In my GSOC project , i plan on adding *.wav support* to commons ,since its not patent encumbered i think it should be fine Context: "Pronunciation Recording Extension" https://www.mediawiki.org/wiki/User:Rahul21/Gsoc I would like to get the communities feedback on this. Is the reason that the dependencies you found all require this format?
