Apple and Telos Push the Internet Audio Envelope with Audioactive Live MPEG Streaming

Cupertino, CA. Apple Computer, Inc. continues its push into the Internet audio domain (see previous story on Apple’s VCD “Virtual CD” technology introduction) with aggressive support of a new live audio streaming system.

Apple is partnering with Telos Systems to deliver Audioactive™ Internet streaming. Apple plans to debut Audioactive with a live webcast tomorrow (Sept.27) featuring the cranberries and Me’shell Ndegeocello, live from Shoreline Amphitheater in Mountain View, CA. (6:00pm PST, 9:00pm EST).

Apple plans to deliver all of its future live webcasts in Audioactive format, including upcoming dates featuring Black Crowes (Sept.29), The Samples (Sept.30), and The Ugly Americans (Oct.2), all from the Fox Theater in Boulder, CO. Upcoming performances from the Strand Theater in Providence, RI are expected to be announced at a later date.

Audioactive is designed for live webcasting, rather than pre-recorded audio-on-demand materials. It is fully compatible with Macromedia’s Shockwave™ plug-in and Shockwave audio standard, so that millions of web surfers who already use Shockwave can automatically receive live Audioactive broadcasts. For audio that is not streamed live, tools like Macromedia’s Director™ can provide the editing, processing, and compression necessary for creating audio files.

“I think people are going to be blown away when they hear this,” says Steve Church, President of Telos Systems. “We’re going to demonstrate that audio on the Internet can have quality that rivals traditional broadcasting.”

Telos plans to implement the IP Multicast standard in Audioactive. Apple has already announced IP Multicast support in its QuickTime TV environment, which sends live audio and video over intranets (local-area IP networks), and potentially the Internet. Many network implementation experts consider IP Multicast to be the best near-term hope for solving the bandwidth problems inherent in moving audio and video broadcast media to the web.

The Telos Server System for Audioactive is implemented on Apple’s Network Server 700 running under AIX. The key hardware component enabling live audio streaming is the Telos Netcoder.

Netcoder is a dedicated hardware-based encoder, which offers much more processing power than systems bound to general-purpose CPUs. A five DSP-chip compression engine performs MPEG-2 layer III bitrate reduction, the most powerful audio method endorsed by the competitive MPEG standards process. On the core compression technology, Telos partnered with the audio and multimedia division of Germany’s Fraunhofer Laboratory, a world leader in pure research in the audio compression field, and the inventor of MPEG layer III.

In the upcoming webcasts, the system will deliver three feeds of increasing quality: one for 28.8 users, which results in better than AM quality audio; one for 56K (single-channel ISDN) users, which offers near FM quality audio; and one for 96K (2-channel ISDN or better) users, which offers near-CD quality audio.

“Apple continues to demonstrate its multimedia leadership on the Internet. We are now in a much improved position to show off our capabilities to music lovers who surf the Internet,” said Steve Franzese, V-P, Interactive Marketing and Online Services for Apple. “We are also pleased to find a technology ally with significant experience and a similar commitment to the music industry.”

Telos Systems is based in Cleveland, OH. The company was the first to apply DSP technologies to audio broadcast products. The Telos range now includes high-fidelity ISDN audio codecs for remote broadcasting, systems for call-in talk shows, and audio processing equipment for FM radio stations.

Pentium PC and Power Mac users are invited to download the free Audioactive player (helper application) in order to listen to the live music webcasts. If you don’t want to wait for the webcasts, you can hear examples of Audioactive streaming right now at the Apple Webcasts site.

With a T1 interface, this one goes for $2,750 (US). The dual-processor version features a peak performance of 74 Mflops, two stereo codecs, and 512 Kbytes of SRAM per DSP.

Creative Tehcnology Jumps Onto the Web & Net Bandwagon with NetSynth, WebPhone

Milpitas, CA. Creative Technology Ltd., of SoundBlaster™ fame, and the world’s leading provider of multimedia products for personal computers, today announced extensive plans to move its product lines towards net and web worthiness.

The key audio product involved in this shift is NetSynth™, a Sound Blaster compliant software synthesizer licensed from Seer Systems. NetSynth plays high-quality MIDI on-line. It offers wave-table synthesis technology, 32-note polyphony, and high-quality reverb, so users can experience a sound fidelity not commonly found from Internet sources today.

It also supports physical modeling of audio, implementing waveguide synthesis via Sondius® technology from Stanford University. NetSynth includes one WaveGuide instrument, to demonstrate the richness available through this relatively new synthesis technique.

The software engine of NetSynth is also available to OEM’s supporting SoundBlaster cards as WaveSynth™.

Creative is also jumping in to Internet telephony, with WebPhone™, a point-to-point communication device that operates like a real phone over the Internet. It comes bundled with a SoundBlaster card. The WebPhone has an interface like a cellular phone, and it features full-duplex audio, speed dialing, voice mail, and e-mail capabilities.

Other audio technologies that Creative is touting as keys to its Internet push are its own 3D audio simulation and SoundFonts™, as well as RealAudio from Progressive Networks, which will be bundled with its Internet-ready products.

Audio On Demand Will Go Mobile in 1997 with Listen Up

upertino, CA. The audio-on-demand market continues to heat up. A month ago, Progressive Networks introduced RealAudio Player Plus software that allows web surfers to tune into personalized audio content on the net as if scanning favorite stations with a radio receiver. Now, Audio Highway aims to go one better by delivering personalized audio content to listeners on the go.

Audio Highway yesterday announced the Listen Up™ player, a small, portable device which delivers personalized audio content to “information-hungry, on-the-go consumers.”

“With a Listen Up Player and an Internet account, consumers will be able to peruse and select audio versions of news, general information, entertainment, education, books and business selections for storage and replay through their player,” says Nathan Schulhof, President and CEO of Audio Highway. “Coupled with the Internet, Listen Up gives consumers the freedom to select the audio content they want to hear and a mechanism to hear it when and where they want to.”

The Listen Up Player is just out of final design. The company says it will retail at $299 (US). It is similar in size to a typical pager, approximately 4 x 2 x 1.5 inches, and it weighs less than four ounces. Sound is delivered via headsets or through transmission to an automobile or home stereo system.

Audio Highway will initially store audio selections on its web servers, where Listen Up customers will be able to view and select personalized audio selections. Once chosen, audio selections will be delivered to the hard drive of a consumer’s personal computer, then transferred to a Listen Up player via a pass-through parallel port.

The Listen Up player that Audio Highway plans to ship in early 1997 will store up to one full hour of audio content in internal memory. It will also include a Listen Up docking station, headphones, AudioWiz™ system software, and a car adapter. It will run for three months on two AAA penlight batteries.

“We will begin national field testing of the Listen Up Player this November,” Schulhof said. “We will formally introduce Listen Up, Audio Highway and its other products and services at the Consumer Electronics Show in January 1997 in Las Vegas. We plan to begin shipments of Listen Up players that same quarter.”

At launch, all Audio Highway content is going to be ad-supported, and delivered free of charge to consumers. For every hour of selected audio content, consumers will receive three minutes of audio advertising messages, in six 30-second spots.

Audio Highway has already signed agreements with a number of media companies to provide a wide selection of continually-updated audio content to its customers. Among the initial content choices available to Listen Up consumers will be tens of thousands of selections ranging from news, books, self- improvement programs, magazine articles, radio and television programs and movie reviews.

Content providers taking part in the November trials of production units include Associated Press, Berlitz, CMP Media, SyberVision, Harper Audio, Newsweek, PR Newswire and Time-Warner Audio Books, among others.

Audio Highway customers will also be able to forward email messages to their Listen Up players. Audio Highway software will be available to convert text email messages into electronic speech for future playback in a mobile environment. As a mobile digital recording device, Listen Up players will also allow consumers to record messages that can be forwarded to individuals with email accounts for future playback through another Listen Up player or a multimedia PC.
