First, there's a Wikipedia page here:
Then there's an oh-so-typical annoying
AF wordpress (I HATE wordpress) page here:
This article is resplendent with technical mistakes
typically made by non-engineers, media reporters who are
attempting to quote and sound knowledgable, lay people,
and so on. The explanation is a bit rushed, and peppered
with technical non-sequiturs. Here's an example:
mobile communication technology, low frequencies are also
used to optimize signal transmission."
This of course technically has nothing
to do with anything. But if you read between the lines
you can easily discern the sociological concern with phenomena
they don't understand and are disturbed by or afraid of,
which is fair. And there seems to be nowhere to turn to
for any kind of help or perhaps sympathy.
Really this is something the IEEE
should address in a cognizant fashion. The underlying
issue is there is a HUGE disconnect between real engineering
and the public, and because no one has any attention span
any longer, (an artifact of social media) a full and coherent
explanation (pretty much of ANYTHING) would take
too long and put everyone to sleep. And the language barrier
between plain folk and many/most engineers is, sadly,

Separately, in my 30+ years of tech
support, I have discerned that ALMOST NO ONE knows what
"Hum" is. People report 1kHz oscillating as
"hum". They report Square wave buzzing as "hum".
They report 59.94 video vertical interval beating against
60 Hz powerline noise as "hum". To be PERFECTLY
CLEAR, "HUM" is ONLY a 60 Hz ground loop or
120 Hz sine wave or close to sine wave power supply issue
in North America and 50 or 100 Hz similar in Europe. EVERYTHING
ELSE is a "noise", or a "tone", or
a "buzz". Note that in the NEXT issue (V3) of
CD I will have short demo tracks to explain this carefully,
coming spring 2021.
On Art Kelm's fabulous site www.Ground1.com
there's an explanation page of power / supply issues and
'noises' which might be further assistive: www.ground1.com/problems.htm

People often ask me
about "tweaking" options, whether it's ripping
your own CD libarary to WAV or FLAC files, or even for
some purposes 'better' MP3's.
Let's say you're ripping
some 70's or 80's rock and you notice there's not much
low end, the maybe the vocals sound nasal, the cymbals
are messy, whatever.
The REASON, by the
way, of why there might not be much low end is that often,
in the studio, there was so much low end in the monitors
(gotta get the vibe, you know) that there winds up not
being enough in the mix. But onward.
You should try OCENAUDIO
. It is a REALLY free, fantastic program from Brazil;
it works on windows, macs, and linux; it accepts all sorts
of DAW "plugins" (free or not free) and you
can do all sorts of things in real time. It "ESSENTIALLY"
is a free almost Steinberg Wavelab. Not that it's
a ripoff of any sort; it is a separate effort.
It is rock stable;
it has parametric EQ and a fantastic 31 band graphic with
1/2 dB steps - just hover over each freq and roll your
mouse wheel.. It has everything from noise reduction to
compression and limiting to the somewhat overused and
somewhat misuderstood "normalization" - in fact
2 versions of it. You can do non-destructive editing.
You can A-B things in real time. It will both open and
save to ANY format you ever heard of; and you can correctly
edit the metadata (and even add your own picture).
You do NOT need any
fancy stuff on your computer. Just rip a CD, load the
song into Oecnaudio, and mess around! You can record WHILE
on a web page, for instance YooToob, if that's your thing.
Once you set the levels by experimenting you're good to
go, and of course you can tweak the levels later - you're
safe as long as you don't clip anything !
OK, there is one caveat:
there are no instructions. But it's far better and easier
than many other things out there, and really free, no
nags, no spyware. Enjoy!

as opposed to a "nothing". so it's no longer

The issue of the speed
of sound has come up many times and I thought
I'd finally do something about it. Don Davis in his book
Sound System Engineering, uses 1130 ft/sec
and that is what I have used for the last 50+ years (!!!!)
of calculations. Considering the effort put forth by humans
measuring the speed of light, the relative ambiguity of
the speed of sound is positively amazing.
However certain anal retentive mathematicians
have a plethora of their own ideas about this, which you
might wish to peruse...

A spiritual visit from I. Lirpa
Those of you who are old enough to
have met or read about the interminable Mr. Lirpa will
agree with me that ANY visit from the esteemed gentleman
is an honor, all jokes notwithstanding. For years his
brilliant and weighty (literally...) inventions graced
the pages of Audio Magazine, and it is with a tip of the
historical hat that I ever so humbly present some offerings
which I can only guess were inspired by I. Lirpa's genius.
Oddly enough, a google search will only reveal scant information
about this secretive genius, yet the mere mention of his
name in certain technical circles is enough to cause joyful
havoc among the constituents.
Actually most of the thanks for this
month's content go to Wes Phillips, one of the resident
geniuses at Stereophile,
whos columns/journals/blogs (as mentioned below, for January
2006) I would not miss (nor should you) and some of whose
links I am honored to pass along.
In memoriam, Wes Phillips passed away
in August 2016. Rest in peace kind sir.

Happy Holidays ! A time for
rejoicing, merriment and presents. And although
'tis better to give than receive, sometimes (just

As for me, I have spent many
years experimenting and tweaking in search of ALL
the holy grails of audio and the one fabulous device
that keeps my attention AND keeps audio fun is the
204. Moan all you want about the purist approach
to audio (much more on this shortly) but the first
time you play a Miles Davis CD through this thing
and hear brushes on the snare that you never knew
were there, or hear a bowed bass playing way, way,
way in the back of the studio, you will be hooked.
And the first time you play some rock n roll CD
which used to sound like it had cardboard drums
and spitting rattlesnakes for cymbals and now you
can make it sound, well, "pretty darned good",
you will really love it. I have mine
on an umbilical cord (made from Mogami 2931, here:
) so it can sit on my lap and I can play with it
for each song. I guarantee this is the most
bang-for-the-buck fun you will ever have in audio,
for an MSRP of $399, and you need 4 RCA-RCA cables
and 4 Phono Jack -->Phone Plug adapters necessary
to interface with most home systems.
I arranged to have Colin Miller
at Secrets of Home Theater and High Fidelity check
one out for himself, and he has written a most remarkable
and complex review HERE.
I have also very successfully
set up 3 units ( = 6 channels ) patched in the analog
outs of a DVD player; this gives you awesome control
over all 5.1 channels of a home theater surround
presentation, ( I suggest doing this BEFORE any
Bass Management) and does a compelling job of improving
essentially anything that goes through it. Aphex
also makes a plethora of other wonderful audio processing
devices, each exemplary in their class. While most
of the processing devices I mention are intended
for professional applications, there are many reasons
to implement (or at least experiment with ) such
goodies in any exotic higher-end audiophile ( i.e.
home as opposed to 'studio' ) system. While
adjusting 36 controls might seem slightly daunting
to some, it's nothing compared with some mixing
boards with 7,000 knobs. And in all seriousness
you get used to the unit operationally VERY quickly.
Now don't get me wrong. We could
spend DAYS, if not a lifetime, discussing about
what's right or wrong about recording and mixing
audio (or whether it should be 'mixed' at all...)
and the various combinations of setups, microphones,
placement, mic preamps, wire (ahem, interconnects...)
power amps, and monitor speakers that are necessary
(or not) to capture the elusive soul of the recording,
ideally in its 3-D holographic acoustic space, and
preserve this musical splendor, with all its emotional
nuance, for days or generations to come. Whew!
But what we have, right or wrong,
for better or worse, at the end of the day, is a
REPEATABLE CD (or DVD or tape...) in our
hand. That CD, or DVD is not going to change - it's
going to be the same today, tomorrow, and next week,
(hence the oft-maligned "perfect sound forever"
line...) therefore you CAN experiment with it and
A-B various combinations of settings or preamps
or amps or speakers just as a listening experience
in and of itself, always knowing that you can go
back to square one, just in case.
Here's a spin... If we extrapolate
certain philosophies, such as espoused by Lexicon
and Yamaha - and I love to play devil's advocate
here - we might purposefully make original [studio]
recordings which are dry and 'confined' (perhaps
just close miked), and then process this dry sound
totally "choosing" the psychoacoustic
playback space, and presumably position within that
space. The playback space would be resynthesized
from algorithims made from measurements made at
all the world's great acoustic auditoriums... or
simply "invented" from front panel settings...
or perhaps drawn on a computer screen.
If we examine this philosophy
from a classical standpoint, we can then playback
a piano solo and choose whether we are in Carnegie
Hall, or the Boston Symphony - or in Smoky Joe's
Cafe. We could even introduce the clinking glasses
and background conversation chatter into the surround
channels if we wished.
But imagine we play back a rock
"concert". Perhaps we want to catch the
vibe from out in the middle of the audience. Perhaps
we want to experience what the musicians hear onstage.
Perhaps we want to feel as though WE are the guitar
player, standing RIGHT IN FRONT OF that stack of
Marshalls... or perhaps we want to A-B all of those
positions and then decide which we want to play
again later. Technically this is certainly possible,
if not a totally plausible scenario.
All if not most of the "party
modes" (and resynthesis modes, and anything
above 5 channel surround) built into modern home
theater receivers are an implementation of this
philosophy to some extent. Of course you can get
carried away... playing the London Symphony through
a "Smoky French Cafe at midnight" synthesized
reverb switch position might not exactly be your
cup of tea. Or it might.
There's a very interesting psychoacoustic
paradigm which takes over after awhile. As mentioned
below, playing with a studio reverb processor, a
pair of headphones, and a single input microphone
can be wildly entertaining. But as you slowly increase
the reverb parameters, something odd happens: as
you listen, your entire psychoacoustic mechanism
seems to phase lock onto this new "sound"...
until IT becomes the norm, and turning the reverb
down or off then becomes "wrong". This
whole enjoyable and remarkably educational field
of experimentation is not to be missed by any serious
student of the world of audio.
I had the pleasure of helping
to design and build what was considered one of the
very few ultimate equalizers in the world, built
into the Crystal Sound recording and mixing board,
designed by the late Andrew Berliner and an illustrious
plethora of outside consultant engineers. There
were many occasions when visiting mixers and audio
engineers were literally moved to tears when they
would say that for the first time in their life
(or career...), they turned a knob and finally some
electronic circuit responded in an emotionally fulfilling
way that they had only previously heard in their
Equalizers are fun. Equalizers
are interesting. Equalizers are dangerous. And of
course equalizers don't make anything equal; they
help to make things NOT equal !
If an A-440 note played
on a trumpet and an A-440 note played on a guitar
were "equal", than they would both
sound the same! The fact that they are NOT equal,
and have a completely different attack, sustain,
decay and release envelope, and have differing
amplitude and phase relationships pertaining
to EACH part of their harmonic structure, is
the essence of what enables us as listeners
to both recognize them and tell them apart.
Imagine two identical Martin acoustic guitars,
one with metal strings, one with nylon strings.
And as we get closer and closer to the "same
sound" one of the differentiations is the
panning position in the stereo mix. If we were
to hear these two instruments coming out of
the same mono speaker, we would be VERY hard
pressed to tell them apart.
So learning about equalizers
and how to use and abuse them is also very entertaining;
and while the more dramatic use would be when an
EQ is applied to each separate microphone channel,
you can certainly enjoy when the overall stereo
2-channel mix has been "fixed" (or broken...)
with an overall equalizer. During the mastering
process, MOST of the time, an equalizer is
applied to the overall mix as part of the magic
"final sonic seasoning", one of the last
steps before you, the listening and tasting audience,
get to taste the audio wares.
Probably the number one equalizer
ever made and available for purchase especially
for the home has to be the Cello Audio Palette (a
Stereophile review HERE)
built by the real Mark Levinson. Good luck on finding
one: it's a bargain at $30,000.
A more affordable and SUPERB
equalizer, with exemplary circuit design and performance,
is the Meyer
CP-10 . This is one of the very few devices
capable of properly fixing what most people refer
to as "room problems"... except that you
cannot really fix a "room problem" without
fixing the room itself, but you can attempt to compensate
somewhat in the opposite or inverse direction so
that you are attempting to subtract from the audio
coming out of the speakers whatever the room anomaly
is; in the hope that two wrongs make a right. Sometimes
they do. Sometimes the result is like seasoning
food - a little goes a long way and too much is
simply too much. But the joy of discovery and experimentation
-- that is the gift.
Many other companies make EQ's,
from combinations of parametrics to 1/6, 1/3, 1/2
and one octave adjustment points; from crossovers
to simple in-line devices that are patched in if
necessary or desired; the world of EQ is an amazing
one that should be part of your audio experience.

will pleasantly overload your inputs for days.
Perhaps you're located in the
chilly northern parts of our fair land, and you
need something to warm you up. Well TUBES
RULE as you will no doubt notice if you
where Eveanna Manley will keep you warm and entertained
for hours with her unique brilliance and awesome
We have our own links section
devoted to tubes on links PAGE
4, as well, and there is a nice page of tube
(ahem, valve) links here: www.audiotools.com/valve.html
There are plenty of interesting
and fascinating tube designs out there. Here are
a two: Jim Fosgate's all tube surround sound processor:
; and Kevin Hayes offerings: www.vac-amps.com
There are also other processors
that are simply interesting, weird, bizarre, but
nontheless fun, and I would be remiss if I didn't
include professional reverb /echo devices. I once
spent a week one night buried under a pair of headphones
connected to a Lexicon PCM70; the input to the unit
was a SINGLE MICROPHONE sitting on the table. Simply
playing with the sound(s) of my own and others'
voices kept me enraptured for a long time. Our own
Lexicon, in Waltham, was and is one of the original
manufacturers of professional digital processing
/ reverberation devices, and their studio units
are the standard of the world. Investigate them
We all know that much of the
time, one hand has no idea what the other hand is
doing: the AM radio world doesn't speak to the FM
radio world; the HIFI world doesn't speak to the
Surround-Sound world; and as an even more extreme
example, the live sound world (i.e. rock concerts)
doesn't speak to the world of installed sound, such
as houses of worship and discos... neither speak
to the "70 Volt" world of distributed
sound in airports... and yet their common denominator
is audio, amplification, speakers, microphones,
and so on. Yet the philosophies, jargon, buzzwords,
and so on are rather different. MOST of the so-called
PRO audio equipment, while suggested for the +4
world of "Pro" nonetheless interfaces
quite well, thank you, with the "consumer"
world of "-10". And yet, because
of dealership and distribution, the worlds of HIFI,
Pro, "Installed Sound" and MI hardly ever
mingle. That is one reason when I suggest (or demonstrate)
a Professional piece in a so-called consumer system
everyone is always so blown away -- they had NO
IDEA such things were possible, or even available!
If you have difficulty interfacing
so-called consumer / semi-pro / prosumer / PRO equipment,
check out these remarkable interface boxes made
by (again) Aphex: the Model
228 Audio Interface and the Model
124 Audio Interface . One of the best tutorials
for interfacing audio equipment is the PDF user
manual of the Model 204, here: www.aphex.com/pdf/204/Aphex_204_user_man.pdf
1.4Mb). The 204 mentioned above needs no additional
interfacing devices other than perhaps an adapter
(or 4 wires...) ; it connects to and from anything.
Take a look at some of the offerings
from Drawmer ( www.drawmer.com ),
TC Electronic ( www.tcelectronic.com ),
Eventide ( www.eventide.com )
( check out the H8000 HERE ),
Behringer ( www.behringer.com )
, and read about the grandaddy of the digital reverb
devices, the EMT 250 HERE
with some nostalgia about the older metal 'plate'
reverbs and how they were built. Do you think that
the 'digital' sound of CD's or DVD's is harsh?
Do you yearn for the kinder, gentler days of soft
tape saturation and pleasantly involving even-order
harmonic distortion? Check out what Rupert Neve
has done, HERE.
If you really want to have the
last word in control of your audio environment,
(bad pun...sorry) check out the Vocal Eliminator:
. Now you can sing along with Sinatra, or replace
him with your own voice track. The history of their
development from simple "wiring channels out
of phase" to today's digital processing is
quite an accomplishment, and a story of dedication.
ALL of the devices listed above
are real hardware boxes. Some processing gadgetry
is ALSO available (or sometimes ONLY available)
as software plug-ins for digital audio workstations,
but even in their best implementation there is no
substitute for the hands-on analog feel of a real
processing device - as cute as the computer screen
pictures make the gadgets look. Some of the processing
devices really are ALL ANALOG (such as the Aphex
devices) while some are all really digital inside,
with an analog front end input and corresponding
analog output, but all digital in the middle. All
the Lexicon and Eventide reverb devices would be
an example of this.
Perhaps you want to have a bit
o' winter fun without disturbing others - you need
headphones/earphones, right? Not those $2.98 (or
even $29.95) foam earbuds that everyone has plugged
into their ipods, but something, well, more serious.
Very much more serious. Of course the BAS has done
wonderfully comprehensive reviews of headphones,
and we have a links section here: links
page 4 (right column, near the middle). My suggestion?
You haven't lived until you connect up Etymôtic
Research model 4's, HERE
directly to your power amp, with buildout resistors,
and a good dual pot... (email me HERE
if you need the circuit) These are not a toy! As
I used to say in my audio store, Prepare to be Amazed!
So here's the scenario: Santa
comes down the chimney, and decides to relax for
a bit, sitting in a superb
leather "theater" chair, a pair of
4's nestled in his beard, a just-big-enough
subwoofer strapped to his chest, and the chair
is loaded with buttkickers,
and they are properly timed for the best psychoacoustic
response with a nice Rane
digital delay, and the Buttkickers are also
equalized with a nice Rane
EQ, and the whole mix is going through a Dolby
Headphone circuit, as our Santa enjoys his milk
... And if I were Santa, I'd put a shot of Amaretto
Di Saronno into that milk or toddy or coffee or...

ON THIS BELOW
November... Time to kick back, relax,
eat too much turkey, and sit in the ol' easy chair (sweet
spot to you audiophiles) and soak up some tunes. But wait,
what shall we listen to this year? Where are the cool
places to find music that's recorded (and perhaps mixed)
well, not some crummy clipped compressed low bitrate hodgepodge
that some kid did on his laptop, but some serious audio
goodies, destined to show off our awesome systems and
fill up our emotional spaces with the nuances of great
performances? Where indeed!!!
To get your blood going, and warm
things up a bit, check out John Novello's new CD,
ORGANIK, on his own site, www.KeysNovello.com

He also has amazing stories to tell and some incredible
books. Don't miss it.
Somewhat more local to Boston is a
most unusual band / group / experience called BellevueCadillac.com

one of my favorites).
The British Library has a master listing
of classical record companies HERE
, and there's an oddly complete and esoteric overall listing
, at Trovar.com, which somehow manages to convey the dusky
smell of the back bins of a record shop in the 50's, and
since I don't have my scent synthesizer turned on, I just
don't know how they do it...

PART B: Now about the malware warning
above, repeated here:
be aware that many offsite links attempt to place
malware, scumware, spyware, scripts, tracking cookies
and ads on your computer, and having a cognizant program
of protection, such as using Webroot AND Malwarebytes
(they get along) is a very prudent move. This
suggestion extends to 2019 !
Besides all the dangers of surfing
naked, recently it was discovered that Sony has placed
an intrusive ROOTKIT software program on certain CD music
discs under the guise of DRM (Digital Rights Management).
There's an article about it here, in Wired Magazine:
and a short but sweet page in PC Magazine, here:
And there have been a number of other repercussions in
the last few days. There's a list of the affected CD's
(with some pictures) on the Electronic Frontier Foundation
The original discovery was made by Mark Russinovich of
Sysinternals.com, who has a superb explanation about it
in his column / blog here:
A fellow writing on Slashdot has his version and list
of the affected items here:
The Washington Post has a number of related articles here:
which deal with the class action lawsuits which are invariably
coming, and news of even more developing scams, where
one emailer claiming to "help" actually is using
the embedded program as a "carrier" for further
Of course the premise is they think
they're doing this because if you are playing the CD in
a computer you are "obviously" copying it, otherwise
what rational person would want to actually listen to
such bad audio?... There is no danger if the CD were to
be played in a CD or DVD player, only a windows computer
where the drive is under control and management by the
It's certainly logical and rational
to view this from both sides. Sony and the musicians are
darned tired of being ripped off (I would suspect
the musicians way more than Sony) and the end user often
thinks he or she can do anything they want with the disc
once they "buy" it, which, unfortunately, is
simply not true.
And this just in, (Nov 11) if you
think you might "have" this problem, Sophos
has published a removal program and rather intense explanation
To add insult to injury, I see that Apple
has started an equally (to me) offensive practice / tactic
of forcefully installing a drive-by mini download of Quicktime,
placing executable startup files and .dll's in the windows\system
folder, and modifying the registry, all by simply visiting
a page where the user has placed a quicktime presentation
into their web page --- the video does not even have to
Personally, I would never install
quicktime, nor would I ever allow it on machines on my
network or that I had control over. On the 2nd driveby,
to a different page, luckily I had Spysweeper installed
and running and it alerted me, (to the next-time-startup
action) but I still had to delete these unwanted vermins,
by both finding and deleting things manually AND by having
to patch the registry manually, a task not necessarily
for the faint of heart. Be aware of the insipid blue weird-looking
"Q" (or maybe it's a "q") showing
up in the systray. Of course you might actually WANT this
on your machine...that's your business. Some people actually
use Netscape and like Bose speakers. Whatever.
In the instances where these surf-by
intrusions took place, I am 100% sure that the posters
of the websites HAVE NO IDEA that this is taking place,
and, most likely simply don't know otherwise and view
Quicktime as an innocuous method of showing a cute video
on their site.
Perhaps in a future column we can
examine and see who is the lesser of the multiple evils,
and what to do about it. Those of you who are determined
to examine this more closely might notice that a surprisingly
large portion of the windows registry is taken up with
reporting your 'playback' activities to the CDDB. And
that's the tip of the iceberg.
For a further glimpse of all of this
and way more of what's coming - and if you think cookies
are bad wait till you hear about PIE - get this month's
issue of PC Magazine or look at the article here:
. It would appear that Macromedia, once the company
that you loved to love, has gone over to the dark side
now that they're in bed with Adobe. Perhaps an in-depth
examination of where this is all going and has come from
is in order, certainly as it pertains to music, the "content"
that we all listen to on our aforementioned audiophile
systems. Stay tuned for that.
Here it is October; time for
Halloween and spooky goings-on in audio, and while
we're at it, other 'sciences'.
Let's contact the dead through
audio - starting with EVP, Electronic Voice Phenomena,
Then we have the psycho-phone,
from Thomas Edison: www.sdparanormal.com/page/page/265918.htm
As Thomas Edison put it, when
working on his own device for contacting the dead:
I am inclined to believe that our personality
hereafter will be able to affect matter. If this
reasoning be correct, then, if we can evolve an
instrument so delicate as to be affected, or moved,
or manipulated by our personality as it survives
in the next life, such an instrument, when made
available, ought to record something (Scientific
American, October 30, 1920.)

No spooky audio page would be
complete without a look into the Taos Hum . The
actual Taos Hum page is here: www.amasci.com/hum/hum1.html
Some audio phenomena are not
necessarily spooky, just "different".
I would suggest that this page and its links offers
a WHOLE new perspective on what constitutes "audio",
as an informational / entertainment / psychological
/ psychoacoustic phenomena:
The root URL is: www.johnduncan.org
We generally mean "audio"
to mean "sound"; and we generally mean
"sound" to encompass 20Hz -20kHz. Theoretically,
of course, mechanical vibration at ANY frequency
might be considered sound, even if it isn't within
the 20-20k realm of our normal hearing perception.
The range of infrasound would therefore extend downward
from 20Hz down to essentially the leading edge of
the big bang, with a frequency of 1 Hz per x-billion
years (that's 1.6 -17Hz ,give or take
a few milennia); and then there's ultrasound, from
20kHz up to some frequency limit that may be arguable;
I suggest 200kHz, since we consider above that to
be radio waves (i.e. R.F., since the regular AM
broadcast band starts at 540 kHz...) although something
could be VIBRATING at 540kHz mechanically,
could it not?... although the medical profession/industry
calls up to perhaps 15 MHz "ultrasound"
so you won't be concerned or frightened that you
are being bombarded with "RF". The word
"sound" sounds so benign.
...and here's a spooky page
(literally) about infrasound and bass: www.barbelith.com/topic/14012
As we enter the realm of Halloween,
we expand outward like an amoebic psuedopod into
the gray moist areas of psuedo science and what
I like to call "comic book science", (i.e.
everything from "Beam Me up, Scotty" to
food replicators to transporters...) and we have
a plethora of people and websites claiming to concern
themselves with "vibrations", the frequencies
of which are not always mentioned or explained...
This site has a "Brain

the page, is here: www.braintuner.com

up. Here's their page on (low frequency) GSR:

so cool I had to include it: www.biof.com

and record voices of dead people, I'd suggest using
a phantom powered mic.

John Mulcahy has conjured up some pretty
nifty software called "Room EQ Wizard" which requires
not only an in-depth investigation, but suggests all sorts
of further study and comparisons as to how we measure things,
are we measuring the correct things, can we hear various
differences with different measuring techniques, and so
For example, a pet bugaboo of mine
has been a ballpark measurement of "THD" when
we clearly know that odd order harmonic distortion and
even order harmonic distortion sound completely different,
and therefore a summation statement of "THD"
is essentially meaningless, because it doesn't specify
which distortion is predominant... This noble effort of
John's has started to provide some discussion on AVS forum,
the thread of which is here:
