2011 NAB Show Product Review: Audio

Despite a wide range of new audio product introductions, there seemed to be just one word on everyone's lips—loudness. But there were plenty of other products at the NAB Show too. Networking and distribution platforms based on MADI, audio over IP, and other transports continue to grow, with manufacturers offering systems that variously combine I/O, mixing, processing, routing, communications and other functionalities.
