Interesting find from www.bells.com. BUSINESS MINDED IDENTITY WITH SOFT & HARDWARE ENGINEERING BACKGROUND WANTED FOR INTERNET VENTURE RE: RF-REMOTE CONTROL. EPAC is a new version of the Perceptual Audio Coder(TM) - developed by Bell Labs, the research and development arm of Lucent Technologies - which is an audio compression algorithm with the highest-quality audio at the lowest bit rates. At 128 kilobits per second, EPAC offers CD-transparent stereo sound. 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. 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. EPAC's variable bit rates and superior audio quality allow the coder to be used in multiple bandwidth applications. PAC was recently rated the best performing audio coding technology in a class of five tested in independent trials by Moulton Laboratories. In this test, PAC at 96 kbps outperformed the MPEG-2 Advanced Audio Coder (AAC). At 96 kbps, PAC also outperformed AAC at 128 kbps based on a repeatable statistical score. PAC is a technology which is supported across broad applications by Lucent. For example, Lucent Digital Radio (www.lucent.com/ldr), a wholly-owned venture of Lucent Technologies, will use PAC in its In-Band On-Channel (IBOC) digital audio broadcast (DAB) system. 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. e.Digital Corporation offers an engineering partnership for th world's leading electronics companies to link portable digital devices to PCs and the Internet. Engineering services range from the licensing of e.Digital's patented MicroOS file management system to custom product development and manufacturing services. For more information on the company, visit www.edig.com. 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 company's web site at www.lucent.com. -------------------------------------------------------------------------------- I am in the process of putting together a new concept of supplying churches and religious institutions with text-audio-visual data utilizing the internet as the carrier. The formentioned Lucent EPAC technology together with e.Digital's MicroOS file management system is just what I was waiting for. However I have a problem which has to be solved. Hence this page. I visualize a stand alone console running on 110/220V not a handheld device as announced. The reader can believe it or not but there is not a single manufacturer on this globe who produces a proper handheld Radio Frequency Remote Control. By proper I mean to say programmable,containing small memory,display and buttons. IR remote controls will not do. Obtainable retail price $ 150 - $ 200. Anyone interested to engineer such a RF remote control interfacing to the e.Digital's MicroOS file management system is welcome to contact me for further communications.

I thought it was the DSP and not MicroOS that allows a player play different formats.

Just my two cents worth -- EDIG has an operating system for FLASH MEMORY. Any number of compression systems could be used on flash cards, but it is the operating system that makes all of these "work". EDIG has an OS that supposedly is more "efficient" for flash as it allows quicker access to files. Correct me if I'm wrong, but it's the OS we should be concerned about -- not whose compression system is being used.
