Are you ready for High Definition Audio?
Here’s what you need to know before making
a decision to buy new audio gear.
OK....so….what I’m about to say isn’t going to
win me any friends among other OEMs. It’s
better not to talk about the elephant in the
room, especially with outsiders. but HD audio
has arrived and conventional audio can’t
reproduce it. Oh, sure, it’ll “play” the music,
maybe even resolve some of the improved
detail, but HD’s huge increase in Dynamic
Range is beyond its reach.
Let me put this in perspective; I’ve been at
this for some thirty years. As a speaker
designer, the last time we faced a challenge to
our product’s dynamic capabilities came in
the 1980s, when Compact Disc arrived.
Dynamic Range, DR, is engineering speak for
the ratio between the loudest and softest
sounds your stereo should be able to deliver.
Vinyl records were rather limited with a best
case DR of 75dB. Transducing that was not
difficult. Then, when CD raised the bar to
96dB, or about one hundred times, meeting
the test was a challenge. The industry pushed
the available technology as far as it could and,
pretty much, more or less, our best efforts
came thru OK. But just barely. It was a
stretch. A lot of us came up short. Dull,
lifeless sounding stuff. Customers noticed,
and the most astute among them sought out
the most successful products. I think that my
company did better than most thanks to
those of you who have owned and enjoyed our
speakers.
Since that time, this has pretty much been the
state of things. But now, thanks to the higher
data density of HD Audio, we have a
technically possible DR of 140dB. So now we
can match human hearing’s range of about
120dB with room to spare. In practice, 110dB,
or so, meets our needs for realistic music
reproduction. So, problem solved on the
source side.
But that does pose a serious problem on the
reproduction side: 110dB is more than 20
times CD’s 96dB, which had already tested the
limits of conventional tech. Is it possible to
squeeze out that much more? Nope. NOPE.
Not even close. A new approach is needed.
Happily, the needed advances are at hand. At
Meadowlark, we’ve been working with them
for several years. Multiple, NCore amplifier
modules and high bit rate Digital Signal
Processing combined with the latest thinking
in transducers.
Here’s my point: our industry will respond to
HD Audio with next generation products,
some sooner than others. So, if you’re even
toying with the idea of buying conventional,
last century style audio gear, my advice is:
don’t.
And please don’t fall into the trap of adding an
HD source to your conventional system, only
to find you’re not getting much more out of it.
That’s like trying to watch 4K video on an
standard def TV. To get the most out of HD
Audio, you’ll need next gen speakers.
Speakers that can handle it.
