Survey: HD Radio Awareness on the Rise
Ann Arbor, MI - Sep 11, 2008 - Research from Mark Kassof and Co. shows that 67 percent of 18-64 year olds have heard of HD Radio. This represents a dramatic increase from a similar Kassof study in 2006, when only 38 percent had heard of HD Radio.
Consumers' understanding of HD Radio has also grown. Now, 21 percent indicate HD Radio delivers higher quality sound, versus 17 percent in 2006. Significantly, 8 percent now volunteer that HD Radio delivers more stations or choices, versus only 1 percent two years ago.
On the downside, this year's research also finds continued misconceptions about HD Radio. Now, 7 percent indicate that HD radio is satellite radio, up from 3 percent in 2006. And 3percent think they receive HD Radio even though they have not purchased an HD Radio-capable receiver.
The research findings are based on 688 telephone interviews in the U.S., conducted from Sept. 4-7, 2008.

APT Worldnet Oslo Updates
Telco and IP codec
The Worldnet Oslo Audio Multiplexer offers a modular platform for the delivery of multiple channels of audio, voice and data over both IP and T1 networks. New for 2008: plug-in voice modules can combine both telephone and intercom traffic along with program audio and data for integrated, efficient networking over high-speed digital links. The range includes a wideband voice module offering four independent, fully duplex 7.5kHz channels as well as four-wire E and M and two-wire FXO and FXS modules for the creation of off-premise extensions and PBX links. Available audio modules include analog, AES/EBU, simplex, duplex and phase-matched options with support for both linear and compressed audio. One key challenge in the migration to IP-based audio delivery is the lack of a stable reference clock throughout an IP network. Worldnet Oslo now offers the option of adding an AES/EBU external synchronization input to the IP transport module. This enables the use of a common audio reference clock throughout all units on the IP network and ensures that the audio clock of all units is stable to achieve the highest audio quality possible over the entire network. Single frequency networking is enabled throughout an IP audio network. This enables highly accurate clock information to be distributed via a Global Positioning System (GPS) in conjunction with the Worldnet Oslo's IP audio transport module. The SFN option on the Worldnet Oslo minimizes FM bandwidth while avoiding the issues of synchronization and phase matching associated with distributed transmitter sites.
Barix Technology Radiobox Pro
PC-free audio streaming
Radiobox Pro is a PC-free, two-channel encoding/decoding solution based on a Barix audio-over-IP electronic architecture. The IP-based platform is ideal for broadcasters seeking reliable STL and IP transport. Radiobox Pro incorporates the Barix Instreamer encoding and Exstreamer decoding technology under the hood along with new features to meet the analog and digital-audio transport requirements of radio stations of all sizes. The 1RU rack-mountable box adds XLR and AES/EBU connections, full-duplex capability and support of uncompressed audio data throughout the transport chain. In addition to STL, Radiobox Pro can be used for solid-state audio playout in the broadcast studio or at the transmission tower. It adds a built-in Compact Flash card slot to store standby programming in the event the live connection is temporarily lost. The presence of the card slot marks a significant design change from the previous version, which included a USB slot for program redundancy. The Barix Instreamer/Exstreamer audio-over-IP technology enables automatic reconnection to the live stream once the connection is back online. Radiobox Pro offers multiple local and remote control options including access to the Radiobox interface from 3G mobile phones. It supports LPCM decoding through Barix Exstreamer technology up to 48kHz and MP3 decoding up to 320kb/s.
