Qualcomm Announces New Audio Standard for the Internet


Qualcomm products mentioned within this press release are offered by Qualcomm Technologies, Inc. and/or its subsidiaries.

Qualcomm Incorporated (NASDAQ: QCOM), a world leader in wireless communications and advanced electronic messaging solutions for the Internet today announced an agreement with Apple Computer to integrate the Qualcomm PureVoice™ audio compression technology into Apple's QuickTime®, enhancing the audio capabilities of applications utilizing QuickTime. Qualcomm's specialized PureVoice sound compression technology combines high-quality with very efficient data storage. Unlike other audio encoder/decoder extensions, PureVoice technology delivers audio files using a specialized compressed format. The result is significantly more efficient transmission of messages with sound quality comparable to standard telephone transmission.

Based on Qualcomm's superior voice compression technology, PureVoice technology is a land-line quality standard developed for IS-95 CDMA wireless systems. PureVoice encoding technology offers smaller file sizes and can reduce file size and transmission time by a factor of 10 or more, compared to other common formats such as .wav. For example, a typical one-minute voice mail message in a .wav file would be about 1M byte in size and take over seven minutes to transmit using a 28.8kbps modem. The same voice message coded with PureVoice technology would be less than 90kbytes in size and normally take less than 45 seconds to transmit.

Voice quality is difficult to quantify and it is usually measured with a subjective metric called the Mean Opinion Score (MOS). In MOS testing, listeners judge the quality of voice encoders by scoring them with numbers ranging from 1 (very poor) to 5 (excellent). The PureVoice technology ranked 4.12 on the MOS test, demonstrating a high voice quality similar or better than that found in regular telephone communications. More specifically, PureVoice technology ranked very close to land-line quality and better than toll-quality.

"PureVoice technology offers the best combination of both worlds: high-quality voice capture capability and smaller file size for increased performance," said Jim DeBello, vice president and general manager Qualcomm's Eudora® division. "Since PureVoice is an audio technology designed specifically to capture voice bandwidths, the difference in quality is easily discernible from other voice capture technologies that have not been similarly optimized."

The agreement states that Apple will distribute PureVoice technology as a system extension to QuickTime 3.0 for Mac OS and Windows platforms, including a full coder/decoder for use during compression, and an optimized stand-alone decoder for playback for Internet and multimedia applications. Scheduled for shipment with QuickTime 3.0 early next year, PureVoice technology will be available simultaneously on Windows 95, Windows NT™, and Mac OS®. The PureVoice technology player-recorder is currently available as a stand alone product and as a plug-in for Eudora® e-mail software via the Eudora Website,

"The combination of QuickTime and PureVoice technology will give users an increased ability to include high-quality voice messages, resulting in a significantly enhanced experience on the Web. We believe that the capability PureVoice technology brings to QuickTime will make it an Internet standard," said Carolyn Goates, Apple Computer Inc.'s product manager for QuickTime for the Internet. "Voice-based communications provide a depth and clarity of information that written messages cannot easily incorporate. Voice inflections, tone and other human communication factors transcend what can be entered by keyboard. By including PureVoice technology with QuickTime, Windows and Macintosh® developers will have greater flexibility to create new, more dynamic Internet and multimedia applications. This new standard for audio quality further strengthens QuickTime's position as the industry standard for the Internet and multimedia development."
