and publishers with greater confidence that their work is being represented with the highest digital
audio quality and is being protected with some of the strongest security technology available," said
Joyce Eastman, vice president of audio initiatives at Lucent Technologies. The Intel Software
Integrity System is designed to run on all Intel Architecture processor-based systems running
Windows(1) 95, Windows 98 and Windows NT clients, and Windows NT servers. Additional
information is available at developer.intel.com. Developed by Bell Labs, the
research and development arm of Lucent Technologies, ePAC uses psychoacoustic modeling - that
is, a representation of how humans hear sound - to compress music in a way that is not noticeable to
the ear. Music is compressed at a rate of 11 to 1, thus reducing the transmission time/bandwidth and
storage by the same ratio, while still retaining its fidelity. Both Intel and Lucent are members of the
Secure Digital Music Initiative (SDMI), the worldwide recording industry's effort to develop an
open, secure access system for digital music. Several recent improvements in ePAC have pushed its
performance levels to new heights, including: ePAC's improved quantization and coding, allowing
higher quality audio at lower bit rates, and ePAC's improved psychoacoustic modeling from Bell
Labs research, which provides CD-transparent sound at 128 kbps. ePAC's variable bit rates and
superior audio quality allow the coder to be used in multiple bandwidth applications.
Lucent Technologies' famed research and development arm, Bell Labs, has been at the forefront of
technology for the music industry for decades, with the introduction of sound for motion pictures in
1926; the invention of stereo recording in 1933; the invention of the transistor in 1947; the
introduction of computer-synthesized music in the 1950s; the introduction of psychoacoustics in the
1960s; sub-band coding of audio in the 1970s; the introduction of linear predictive coding in the
1980s, and the Perceptual Audio Coder in the 1990s.
Lucent Technologies, headquartered in Murray Hill, N.J., designs, builds and delivers a wide range
of public and private networks, communications systems and software, data networking systems,
business telephone systems and microelectronic components. Bell Labs is the research and
development arm for the company. For more information on Lucent Technologies, visit the
