Wiki Campus Radio
One possible use for the Sandbox Server would be to allow Wikiversity participants to chat and record discussions. The goal is to record the discussion, edit it and have a high quality OGG sound file. Discuss possible times above. As a proof of concept a few Wikiversity participants recently used open source software to hold an online discussion and talk about Wiki Campus Radio and the Sandbox Server. I like the idea of having a "distributed time" approach in which people can "layer" comments onto a past discussion. I did not participate in the original discussion, but I was able to add in my comments after the initial discussion.
An edited version (six minutes) of the voice chat session is in
. This edited version was made from the much longer
. I used GarageBand to edit the original sound file. GarageBand will open AIFF, WAV, AAC and MP3 files. I used the GUI audio file converter called Super (for Windows, see this review) to convert the original OGG audio file into an AAC audio file. Using GarageBand, I edited out dead air, speech that was too quiet or too loud as well as off topic dialog. I just wanted a short audio clip that would demonstrate an ability to record multiple people having a discussion. GarageBand is also good at increasing the volume of quiet sounds and reducing the volume of loud sounds, so I was able to even out some very quiet input and some very loud input. GarageBand produces .m4a files, a form of MPEG. For video OGG files, I use the conversion method shown at Podcasting. I decided to try Music Man demo to convert the audio m4a file to an OGG file. It worked fine, but I am in the market for a totally free alternative (note: the VLC media player for Mac OS X did this conversion, but produced an OGG file that is more than twice as large as the file made by Music Man). --JWSchmidt 03:55, 2 February 2007 (UTC) Modified and expanded version.
