Rare indeed is the audiophile who has not experienced—at least momentarily—the strong desire to make a high-quality recording of something. Many audiophiles are not only music lovers, but musical amateurs as well, or at least have family members or friends who sing or play an…

The fundamental object of the invention is to provide...the listener a realistic impression that the intelligence is being communicated to him over two acoustic paths in the same manner as he experiences in listening to everyday acoustic intercourse....—Blumlein, et al, British Patent #394,325, issued June 14, 1933
Seeking a more affordable alternative to the Schoeps, I asked Jerry's advice. His recommendation, the Audio-Technica AT-825 stereo microphone, has the practical advantages of comparatively affordable price (list $595, Markertek $389), slim design (it's the size and shape we usually associate with a microphone), and internal battery power. The AT-825 is designed to be pointed straight along its length at the sound source (unlike a side-address mike, the body of which is intended to be positioned vertically). Clipping the AT-825 into the provided stand clamp so that its legend is visible at…

Two recent listening experiences of mine echoed the overblown praise Jon Landau lavished upon Bruce Springsteen after he heard The Wild, the Innocent & the E-Street Shuffle. But all hype aside, Landau was right: Springsteen was the future of rock'n'roll—or at least what passed for the future of traditional rock in those pre-MTV, pre-techno, pre-house, pre-gangsta, pre-rap, pre-hip-hop, pre-grunge, pre-Mariah Carey, pre-Garth Brooks, pre-sampling, pre-digital days. And I believe that, Landau-like, I too will be right. I have heard the future of audio, and it is digital—digital technology…

The Audio Engineering Society held its 95th Convention in New York's Jacob Javits Convention Center in October 1993. The gathering is both a trade show for introducing new recording products and a forum for audio scientists presenting papers describing their research. Stereophile has found AES Conventions essential to keeping up with what's happening at the cutting edge of audio technology. Consequently, John Atkinson and I spent four days at the New York Convention, with Larry Archibald dropping by for a few papers and exhibits. Peter…

Until now, developers and reviewers of perceptual coders have relied only on listening tests, because conventional measurements provide little guidance. At the New York AES convention two new methods were demonstrated that can provide valuable information about audible flaws in low-bit-rate coders. Both operate on the same principle as the perceptual coders themselves—namely, the concept of "masking" in critical bands (see later).
The cochlea of the inner ear behaves as a bio-mechanical spectrum analyzer. A tone at any frequency…

The internal battle between the head and the heart, between the analytical and romantic sides of our nature, is a difficult one. I'm an engineer, so it seems as if my cold, calculating side should have the upper hand. This is true in a lot of cases; most of my actions and decisions are based on straightforward, logical analyses. However, things like a house full of castaway dogs, or a garage full of quixotic British cars and Italian motorcycles, suggest that my heart holds sway reasonably—perhaps distressingly—often.
This struggle is often in full force when I venture into the…
The Power 3 didn't sound perfectly neutral, however. Its overall character was slightly cool, dry, and distant—exactly the opposite of the VTL's slightly warm, liquid, immediate personality. On the vinyl version of the Ray Brown Trio's Soular Energy (Concord Jazz LELP 111, Bellaphon 180gm half-speed-mastered version), Brown's bass sounded a little more prominent with the VTL, but more consistent across its range with the Power 3. Similarly, the VTL had a bit more midrange and upper-midrange bloom than the SF, so Emily Remler's guitar and Red Holloway's sax were tonally richer and more vivid…
