Today we wanted to talk about three audio conferencing companies that have added USB 2.0 connectivity to their professional audio conferencing product line. ClearONE, Phoenix Audio and Vaddio. Phoenix Audio has actually had USB in the product for a very long time, more than 10 years actually. Phoenix started with a product called the Duet in June 2005. The Duet has a built-in microphone and speaker with echo canceling and noise reduction capabilities. More are on the USB technology timeline here: http://software.conferenceroomsystems.com/ .
