LATEST ADDITIONS

WIth DVD-Audio on the horizon, the standards wars have led to a dizzying number of new format variations. Not only do we have different data-rate proposals, we're not even sure how many channels we need. Which do you prefer: a universal audio standard, or a niche-market approach?

Recently, <A HREF="http://www.analog.com/">Analog Devices</A> announced the world&#198;s first High Definition Compatible Digital (HDCD) decoder chip with 32-bit internal precision. The ADSP-21061 SHARC programmable digital signal processor will enable HDCD decoding to be incorporated into a wide variety of consumer audio and home-theater products, according to an AD press release dated March 26. The SHARC DSP can perform up to 150 million operations per second, and includes one megabit of onboard memory, six DMA channels, and two serial ports. The highly integrated decoder is claimed to perform HDCD decoding without external memory.

Recently, Sound Advice, Inc., a specialty retailer of high-end consumer electronics, announced plans to open five to six stores in Florida over the next 18 months. The company expects that two to three of the stores will be in operation by the end of this calendar year, with the balance to be opened in 1999. Sound Advice is also exploring other ideas, such as smaller-format specialty stores in upscale malls and other high-end retail locations that feature high-quality brand names.

On April 7, <A HREF="http://www.carver.com">Carver Corp.</A> announced an agreement in principle for the sale of 3 million shares of restricted Common Stock of the company to one of its preferred shareholders, Renwick Special Situations Fund, L.P., for $375,000, or $0.125 per share.

"Digital audio quality at analog prices." That&#198;s how <A HREF="http://www.cirrus.com/">Cirrus Logic</A>'s Crystal Semiconductor division introduced a chip that may bring a new level of audio performance to a much wider audience. On April 6, Crystal announced its CS4334, an 8-pin, small-outline D/A converter. The 24-bit CS4334 will support sampling rates of up to 96kHz, and is being marketed as a low-cost, high-quality solution for computer, automotive, and portable audio applications, as well as DVD systems and set-top converter boxes. Crystal claims the new chip is the industry&#198;s smallest delta-sigma DAC.

At the recent <A HREF="http://www.microsoft.com">WinHEC '98</A>, <A HREF="http://www.nec.com">NEC Electronics Inc.</A> made available prototype sample units of 1394-to-POF (plastic optical fiber) repeater boxes that extend transmission of video, audio, and textual data over long distances via plastic optical fiber and copper media. NEC Electronics, one of the first companies to demonstrate this technology over plastic optical fiber and copper and wireless media, is also one of the first to demonstrate transmission speeds of 200Mbits/s over plastic optical fiber.

Not long after the single-disc CD player was introduced, the multidisc changer followed, with products from companies like <A HREF="http://www.sony.com">Sony</A&gt; and <A HREF="http://www.pioneerelectronics.com">Pioneer</A&gt;. Shortly after the changer was introduced, it became the most popular version of the new hardware format. In the past eight years, changers have consistently outsold single-disc machines. The high-end market was characteristically slow to embrace changers, but companies like <A HREF="http://www.calaudio.com">California Audio Labs</A> have been successful in this category with products like the CL-10, a five-disc carousel changer.
