It’s only mid-week and it’s already been quite a trip in the audio codec landscape. Broadcom announced that they are releasing into open source under the LGPL their BV16 and BV32 audio codecs. The relevant page on their web site includes documents outlining the techniques implemented in the codecs and C source code.
I’m not familiar with either of the Broadcom codecs. I see that they are available in some versions of Counterpath’s X-Lite and Eyebeam soft phones. Support for these codecs in hardware is something that I’m yet to determine.
