Uma rádio HD a emitir em 5.1 Surround

Pela primeira vez uma rádio nos EUA está emitir em 5.1 Surround, o «formato» sonoro equivalente/idêntico ao Superaudio CD - ou seja, permitindo (com um descodificador) a recepção em cinco colunas.

Jorge Guimarães Silva esclarece, a meu pedido: «Equivale à passagem do Mono para o Estéreo, mas a primeira transmissão em surround 5.1 foi feita pela União Europeia de Radiodifusão (EBU), em 12 de Outubro de 2003, aproveitando o "Dia da Rádio". escrevi um texto sobre isso em 12/10/2003: http://telefonia.weblogger.terra.com.br/200310_telefonia_arquivo.htm»

«Telos Systems and CBS Radio said WZLX(FM), Boston would become the first station in the nation to broadcast all of their format in 5.1 surround sound using the MPEG system on its HD Radio signal. The change is expected to occur within the next 90 to 120 days. The companies hope the move will attract the attention of Boston-based receiver makers such as Boston Acoustics and Bose, as well as other stations, to get them excited about MPEG Surround sound capability, said Steve Church, chief executive officer of Telos Systems and Frank Foti, president of Omnia. "This is going to create a significant boost to radio's aural impact and will be an important motivation for consumers to buy HD Radios," said Church. The station will hold off on promoting the 5.1 surround until there are compatible MPEG Surround receivers in the market, said Church and Foti, who added MPEG has developed a reference design for receiver makers. Other stations are interested in adapting their studios and music formats to surround sound, said Foti, who added the classic rock and classical formats currently have the most music recorded in 5.1 surround. Telos/Omnia is helping WZLX convert its record library to surround and Fraunhofer is providing the MPEG Surround encoder. WZLX is a Classic Rock-formatted station».
