Actually, wouldn't accept="audio/*;capture=microphone"
basically indicate that the server wish to accept anything as audio?
Which means it's up to the browser to decide what is best (among a list 
of the most common audio formats most likely).

The proper way however would be to do:
accept="audio/flac, audio/wav, audio/ogg, audio/aac, 
audio/mp3;capture=microphone"
indicating all the audio formats the server can handle.

audio/* basically says to the browser that it can send anything even raw 
data or a image as if it was audio,
and the website would have to respond to the user that this was 
unsupported or that they should submit these formats instead.

Although I guess that audio/* could be taken as a sign that the browser 
should negotiate directly with the server about the preferred format to 
use. (Is POST HEADER request supported even?)
