Google is in the early stages of giving Chrome a completely add-on free approach to live audio and video chat, the company's Henrik Andreasson said this weekend. The company plans to integrate the WebRTC protocol first in its open-source Chromium project before rolling it into the regular Chrome browser. The step should give the browser both high- and low-bandwidth audio formats, iSAC and iLBC, as well as use the VP8 codec behind WebM for video.
