LEADING classical recording company Deutsche Grammophon (DG) has produced new technologies, which it asserts substantially improves the sound of records. Dealing with Yamaha, it's started producing CDs employing a new technology that it requires 4D Audio Recording. The very first 4D recordings have already gone on the market in Australia. It's so clear and natural, states DG, "you will not feel you are listening to your recording". You do not require any special gear to listen to that the benefits: almost any CD player is going to do, although naturally the sound is best when performed through great high-fidelity loudspeakers.

Having listened extensively to a few 4D CDs within the last couple of months, then I'm impressed. I've yet to be completely suckered to the illusion which a 4D recording is a live performance. The 4D documents are surely among the very best illustrations of orchestral songs I've heard. There aren't any sonic woods, but also the sound isn't obviously natural as well as gallop. In orchestral collections, each device remains clearly delineated, instead of blurring to a fuzzy melange of sound.
Instrumental timbre, which most elusive of all recording aims, is especially noticeable. The 4D process is largely the job of Klaus Hiemann, also the manager of DG's recording facility in Hanover, as well as the specialized leader Stefan Shibata, also a gifted recording engineer and also one-time roadie for both Elton John and Joe Cocker. It's Hiemann's unshakeable belief that "the only real goal of recording technologies is the fact that it must eventually be inaudible". For many years he's been working together with engineers in Yamaha toward this fantasy: designing gear that could "eliminate the listener's awareness of their specialized moderate, allowing the enjoyment of a totally natural sound quality".
You will find four new elements in the 4D recording platform which they've come up with: a brand new remote-controlled mic preamplifier; a industry-leading 21-bit analog-to-digital converter; a device known as a "stagebox" that sits to the recording platform one of the musicians; along with brand new electronic mixing and mastering procedures. We shouldn't be overly disturbed about the technicalities here. Suffice to state that the stagebox, that retains the preamplifier and analog-to- electronic converter, brings critical phases of the recording procedure as near as you can to the true performance.

By multiplying the long pathway which formerly lay between mic and studio, then the 4D system eliminates significant sources of sound cancelling. A fast word for those techies, also, on 21-bit recording. Regular 16-bit digital recording attempts to recreate the waveforms of audio utilizing 65,536 possible gradations, or even little stairs and steps. Together with 21-bit recording, you'll find over two million stairs and steps, which makes it feasible to replicate a much more precise waveform. It's a tricky business: due for the function with Yamaha, DG claims to possess the sole 21-bit converters available right now.
DG's 4D records could be identified with just a little 4D emblem on the front part of the CD box. For Broadway musical fans, there's a brand new record of Leonard Bernstein's On The City by a mostly operatic cast like Frederica von Stade; Michael Tilson runs the London Symphony. The recording was made in London's Barbican Centre with all of the ambiance of a live theatrical performance: the perfect program for 4D technologies (DG 437 512-2).
A lot more classical records are expected on 4D in forthcoming months: it isn't yet clear if other companies will license the technologies to deliver exactly the same brand new clarity to jazz and rock. SONY Australia has announced four new CD Discman compact disk players: 3 portables plus one designed especially to be used in the auto. Even the D-822K Car Discman includes a special dual-damper shock absorber program, and it can be promised to eliminate the bypassing of brief passages once your vehicle hits a bump. Sony says it could endure shocks as large since 1G _ enough to make sure that bypassing is uncommon under ordinary driving conditions. The player is created of heat-resistant materials to resist the high temperatures created in automobiles left parked at sunlight.

The automobile Discman includes straps to join to auto speakers and power throughout the auto cigarette lighter socket. There's a very small palm- best remote controller, which Sony claims makes for secure operation and effortless access whilst driving _ you do not need to take your eyes off the street. Even the D-882K also offers special digital processing systems which may be employed to add a thumpier bass if this is your fancy, or even to boost low- level sounds which could be difficult to listen to commonly at a moving automobile.
