Xiph.org Offers New CELT Demonstrations

Just before the holidays the folks at Xiph.org put up a nice demonstration page with a lot of detail about their CELT codec. Word of this new offering was announced on the IETF CODEC mailing list.

The samples and explanations provided are first rate. They clearly illustrate the merit in ultra-low-latency for some applications, as well as exemplify how CELT currently fares against other common codecs at a variety of bit-rates and with various types of source material.

SkypeKit: The Next Step In Skype Everywhere

Earlier today Skype announced the pending launch of a beta program for an SDK called SkypeKit. SkypeKit is intended to allow hardware developers to embed Skype client functionality into their devices.

SkypeKit seems to be a logical next step after having recently partnered with LG, Samsung and Panasonic to build embedded Skype clients for their newest HDTVs. I mentioned this previously.

There’s a bunch of coverage of the SkypeKit launch available at various places online. Engadget has their say and some nice pics of the Grandstream GXV-3140 Media Phone running Skype. Also a Litl webbook that looks like it’s running Skype with video.

Considering Our SILKen Future

Much is being made of the recent events in the IETF CODEC Working Group . Specifically, the fact that Skype has included the c source code for their SILK codec in the Draft RFC document.

Dan York has some excellent coverage including a good general backgrounder on the matter. Jim Courtney has also posted something interesting, as has Phil Wolff of Skype Journal.

A lot of what is being expressed seems to me unbridled enthusiasm for what is seen as a bold, even surprising move on the part of Skype. I agree that this is a gutsy move…and one that I applaud. However, I’m also here to reign in the enthusiasm just a bit. Tempering it with a dose of reality we can see this in a larger context and keep our eyes on the larger goal…ubiquitous wideband telephony.

Blabbelon In SILKy Wideband Audio

blabbelonVUC regular Tim Panton has been very busy lately. He was at Astricon where he gave a splendid presentation on the current state of Skype-For-Asterisk, including a live demo of it integrated with Google Wave. He later gave a similar presentation at eComm in Amsterdam, including a demo to the Google Wave team! Of course, we’ve been using his G.722 capable Java plug-in for web browser access to the ZIPDX wideband conference bridge for several months. That has been a genuinely useful bit of software, allowing anyone with a headset & decent broadband to experience HDVoice first hand.
