formats is as follows:
IE 9+ (versions prior to 9 do not support the audio element): MP3, MP4, and WebM
Chrome 5+: MP3, MP4, WAV, Ogg Vorbis, and WebM
Firefox 3.5+: WAV, Ogg Vorbis, and WebM (4+). MP3 and MP4 support will be added to Firefox
but only when a third-party decoder is available.
Safari 4+ and Mobile Safari 3+: MP3, MP4, and WAV
Android (2.0+): MP3, WAV, Ogg Vorbis, and WebM (2.3.3+)
