The Record audio repository plugin, a GSOC 2009 project, has been developed by Andrei Băutu and mentored by Jerome Mouneyrac. You can read an account of Andrei's experience in his blog Nothing fancy, Just blogging.
As always, help in testing is much appreciated. You're welcome to try recording some audio and video in the audio and video test course (login with username test and password test). Alternatively, you can download the Riffly and Nanogong repository plugin from the modules and plugins database.
