Blabbelon In SILKy Wideband Audio
VUC 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.
Having read & listened this far into this series you should now have some grasp of how narrowband (G.711) compares to wideband (G.722/G.722.1) and even super-wideband (G.722.1C) audio for telephony applications. The differences in many cases are quite pronounced, even startling. What you hear in the examples are just the most obvious properties of the encoding, sampling rate and by implication, the available audio bandwidth. It’s worth understanding a bit more about the evolution of the role of the codec over time. This will help you frame up how the Siren codecs fit into the Asterisk realm.
Over the past year I’ve become acutely aware of the problems possible with blog hosts. Even the good ones have trouble periodically. I’m not seriously unhappy with my current hosting company, but I am wondering what’s better. I’m inclined to think that a bone fide dedicated server shared by a handful of users would be better than my current arrangement.
This mornings attempt to get through my backlog in Google Reader turns up two interesting and kinda related news items. First, Kingston Technologies has introduced a line of low-end solid state disks (SSDs) called the
