We’re still on the hunt for a ‘video conferencing/webinar service type thing’ at Open Knowledge and a couple of weeks ago we tried out Mumble.
Mumble is a voice chat application for groups that has been designed primarily for gaming. Mumble is the client application and Murmur is the server application. The client, Mumble, runs on Windows, Mac OS X and Linux and I had no problem downloading it once.
There isn’t a huge amount to say about Mumble, it does what it says on the tin, but we were all extremely impressed with the latency and sound quality. It pretty much felt like you were talking to someone on a good landline, or better to be honest. The reason for this is ‘de-noising’ – apparently this a standard part of Speex 1.1 implementation.
One annoying thing is the text-to-speech feature – which speaks out all the chat messages. Luckily this can be turned off, and I can see some advantages in having it.
I guess the biggest issue with Mumble is that you can’t screen share, so the possibilities are limited. But as a voice chat application it was pretty smart!
There is a good FAQ on the technical aspects of Mumble.
