twittergram.com can now handle wav files
Thursday, June 28, 2007 by Dave Winer.
As an experiment, I uploaded a mini-podcast I did with my parents in 2004. It's a wav file.
There is a new optional parameter on the web service. Scroll down to the section in red to see the change (eventually the color will be removed).
The web interface has also been changed to support wavs. You don't need to know anything other than you can choose a wav from the file dialog and if it meets the size criteria, it should work.
