Speex Joins Xiph To Bring Free VOIP To The Masses
xercist writes "Xiph.org
has added a new project to their plate of goodies-
Speex.
Speex is an audio codec specifically for, you guessed it, voice.
It has integration with Xiph's
OGG
container, but is mainly being used right now for VOIP.
There is currently an XMMS
plugin
available, and is also supported by
LinPhone,
OpenH323,
and
GnomeMeeting.
Asterisk PBX
is working on adding support.
This is not a new project -- Jean-Marc Valin has been hard at work writing
the codec for quite a while now. However, Jean-Marc is now a full-fledged
member or the Xiph.org team, and in celebration, Speex beta one is being
released.
Xiph.org has brought you
(or is currently working on bringing you)
Vorbis,
Tremor,
Theora,
Tarkin,
Icecast2,
cdparanoia,
now Speex,
and, of course, the
Moaning Goat Meter.
This is a LOT to do, so please
donate
to show your support."
I've been playing around with speex when i was working on an audio conferencing. It's a simple api, and the audio quality comes out okay for voice too. (unless you try sending music through, then it really just craps out)
If only I could get the windows side of the cross-platform audio caputre stuff so nice.

Voice over IP doesn't send voice data over TCP, it uses UDP. UDP isn't complicated at all - it just gives you a way to uniquely identify a machine and say "send this data to it." It doesn't even guarantee delivery of the data. It's probably the best, most accepted way of sending addressed, digital data over wires.
Now, imagine you're a company that's just put an office up. Would you rather install two sets of wires to each desk (ethernet and phone network), one of which requires you to get a licensed contractor in if you need work done on it? Or a single set of wires which can be maintained by the people who run your computers?
(I am the Speex author) There are already at least two Windows front-ends: here and here. There may be others I'm not aware of. Note that I haven't developed of tested any of these since I don't use Windows.
