This is a module that uses the WAMI audio recorder http://code.google.com/p/wami-recorder/ and lets anyone record a message onto a Web page. The message is saved as a file in Drupal.
It currently works as a file field widget.
For user sessions, before actually saving the file permanently, I have a function called wami_jam_session_set(), and wami_jam_session_get().
Then, I use this capability to create a WAMI field widget.
I would like to make it work with the File Field "Sources" module, but currently it's not quite compatible yet. If it was, then you could allow users to either upload audio files or record a file directly from a Flash recorder on the Web page.
Is this something that could be turned into a Drupal project?
