Is Dr. Doherty saying that the now common advice to not worry about low recording levels is not good?

Dr. Douglas Doherty, "Is Lack of Warmth an Inevitable Trait of Digital Recording?" http://www.soundonsound.com/sos/jul12/articles/sounding-off-0712.htmAs an explanation for ONE of the factors for what he believes is inferior sound
quality with today's recordings he states: Quote:
In the old days, we always kept levels as far
above the magnetic tape’s noise floor as possible, but below its overload point. With
the digital revolution and the eradication of magnetic tape, noise floors apparently
became a thing of the past. So no more worries: just give yourself plenty of headroom and
then normalise. But — and it’s a very big but — lower digital levels mean lower bit
counts, and lower bit counts mean less detailed recordings ...
I grew up in this "new" generation of 24-bit
sound cards, where "peak at -12dBFS or lower" seems to be the generally recommended way to
record (as opposed to having everything up closer to 0dBFS). Is Dr. Doherty suggesting
something closer to the latter?
Thanks for the thoughts of all you guys who
really know what they're doing!

There a fair bit of bollox in that " sounding off". Cold digital recording s do NOT
develop from " lower bit counts giving less detailed recording " ( the biggest pat of the
bollox). it's from less harmonic distortion.
Less " phatness" if you will.
it's also from a lot of recording by a lot of people who only know some of the
Information to get " good" recordings.

But -12dBFS peak is not 'low'. We're dealing with comparable levels as we did to tape. The
only people who think levels are low are those who misunderstand what the meters are
telling them and get stressed about seeing 'unused' headroom!
And I still
don't get this obsession about 'warmth' - a digital recording is as 'warm' (and I've yet
to see a definition that allocates a consistent meaning to this word) as the source you
record.
It seems that many people want to record a source and have it
magically improved. I suspect that people purportedly looking for 'warmth' are really
looking for recordings that are 'better', but don't have the tools or skills to do it
themselves - hence the search for a 'magic' box, plug-in, or DAW.
And
'normalise'?! Where's a face-palm when you need it?...

Anything to oblige a friend....
I've only glanced at the article m'self thus far... but what I've read was enough
to raise an eyebrow and utter a sigh.
Leaving aside the physics and maths, I'm
with the Elf. You make the recording sound as you want it to... You have to learn to use
the tools at your disposal to get the sound you're seeking.

Agreed. I'm surprised that someone who owns such a company is spreading such

IIRC -12dB is only using 2 bits less than the full 24bit recording (6dB is a doubling in
level - voltage - and so equates to one bit of the data word, so 12dB equates to two
bits), so you'd still be getting a 22bit recording resolution. Since the noise floor of
the AD is probably down in the -100dB or so area, you could happily record at -24dB and
still get a 20bit recording with a -70dB noise floor (as long as you don't have other
analogue electronics contributing noise and bumping the noise floor up massively along the
way).
Remember the best CD remasters were transferred from tape at only 20bits
until quite recently, with a noise floor on tape that was at least 10dB higher than this,
so for individual tracks we're still in the realm of untold luxury of quality!

I was
astonished to see that he had written that. Dr D is a very intelligent and knowledgable
chap, but that is just misguided IMHO.
Narcoman and Elf have made all the
sensible, relevant and pertinent points, but just to labour the point...
Quote:
lower digital levels
mean lower bit counts, and lower bit counts mean less detailed recordings ...
The first part of that statement is
clearly true. For every 6dB below 0dBFS the audio will exercise one fewer bit in the
24-bit word that describes the amplitude.
However, to suggest that results in
a less detailed recording is utter nonsense. It results in a noisier recording, certainly.
The signal-to-noise ratio is degraded -- just as it is with any analogue system used in
the same way. But the audio has no less 'resolution'.
I explained all this in
an article called Digital
Problems, Practical Solutions four years ago.
The erroneus idea of
reduced 'resolution' with lower wordlength usually comes from demos like this 8-bit (undithered) piano recording in which you can clearly here
distortions and artefacts and all manner of nasty things. Some would say that is proof of
'less resolution'...
However, that example is not representative of the
complete digital process because it only demonstrates crude amplitude quantisation, which
is inherently grossly non-linear. All digital audio systems worthy of the pro-audio
industry use dithering to perfectly linearise the quantisation process. This results in no
distortions, no artefacts, and only a smooth benign noise floor -- exactly like any
analogue recording chain or device.
Here is the same piano recording but properly dithered. You can hear a
perfectly clean and detailed piano recording there, with no loss of resolution whatsoever.
However, there is a constant noise floor...
Taking it to an extreme, here is a 3-bit recording of the same thing, but with 'noise-shaping'
dither which makes the noise floor slightly less objectionable through a spectral
shaping process.
That's really just a three-bit recording. So if you set
your recording levels to peak around -100dB that's pretty much what you'd be left with.
Does that really sound like it's lacking resolution or detail? I can hear all the
subtleties of the performance and the room acoustics buried in the noise.
I
have seen and heard Prism Sound demonstrations where they have shown it perfectly possible
to hear a clean, undistorted signal 15dB below the theoretical limit of a 16 bit system if
proper dithering is employed with good quality converters.
So sorry... it's a
common argument against digital audio, but it simply ain't true.
Quote:
I grew up in this "new"
generation of 24-bit sound cards, where "peak at -12dBFS or lower" seems to be the
generally recommended way to record
It is the recommended way because it is the technically correct way, the same way
as we evolved the use of analogue systems, and for exactly the same reasons.
The issue, as the Elf has said, is that people get scared when they seen unused space at
the top of their meters, becaues they simply aren't used to seeing the headroom margin
revealed in that way. Analogue meters just don't show the headroom margin -- but it's
still there and for very important reasons.
And the 'warmth' thing is as
Narco said -- a lack of masking harmonic distortions that make things sound cuddly and
make mixing rather easier because the details aren't as exposed. It's not hard to
introduce similar effects to a digital system if that's what you want, via plug-ins or
external analogue hardware. But as far as I'm concerned having a clean and faithful
recording chain is a good thing.... and I happily record with peaks under -10dBFS and
average levels around -20dBFS without any concerns whatsoever.

Yeah, the implication is that this loss of 'resolution' and detail makes things sound bad
in relation to analogue. But since all the reduction in word length means is that the
signal is closer to the noise floor, then by that logic digital should sound better than
tape. Strange article. J

Strange indeed. He does make a lot of very good points though and I agree
completely with his suggestion that:
Quote:
...digital signal processing that repeatedly loses bits
...(bonkers bit deleted)... and you have a recipe that can result in sounds lacking any
sense of reality. Couple this with a plethora of low-cost microphones, single‑chip mic
preamps, A‑D/D‑A conversion based around a single chip alongside rudimentary analogue
interface circuitry, and we begin to approach an explanation for what’s going on
There's a lot of truth in
that.
But...
Quote:
Digital coldness is actually a lack of fidelity
Doesn't tally with my experience. Record an
orchestra, or even just a voice to digits and it comes back sounding just like it did
leaving the console. Do that with tape and you get something back that sounds obviously
different. Often it's 'nice' different, but different all the same -- which to my
understanding of English implies a lack of fidelity. Conversely, it also that means that
the digital system must have better fidelity, surely!

Doesn't this all boil down to what we like to hear. It doesn't really matter what the
graph says. I think that what happened was that people of a cetain vintage (me included)
"got used to" hearing that analogue warmth (whatever that is, distortion etc) and that
anything else sounds sort of wrong.
You can tell them until you're blue in teh
face that digital has better fidelity (true copy of the original) but they will just never
ever buy the argument because when they listen, it doesn't sound "right" to them.
It's not just anal boffins arguig about this stuff though. It's all types of people and
people with access to the best gear and the best rooms and the best reproduction
equipment. Kate Bush (and she's listened to a playback or two i'd wager) was on the radio
talking about her "Director's Cur" record and she said that she was going to work to tape
because it sounded warmer, that she missed that sound.
Perhaps there's a
confusion about "fidelty", perhaps because people used to use "HiFi" and it has "HiFi"
written on album covers, they associate that sound with "fidelity".
Or
perhaps because there isn't a signal chain in the world that can make a violin sound
exactly as it does if you're sitting in the room while it's being played, the analogue
reproduction is a better approximation to the ear.
It's all about what we hear.
So, less fidelity, but maybe less is more.

Sure...Nobody is arguing that tape doesn't sound different. And of course it may well
sound subjectively better, to some or even most people. The point that we're arguing is
that warmth and 'beauty' that tape has is nothing to do with higher fidelity. Quite the
opposite. The probem with digital, if you approach from the 'digital is a problem'
standpoint, is that its fidelity is too great. In that respect the article is arse about
face. The point is not that digital is 'just as good'...That's up to the individual, and
of course Dr Doherty is quite within his rights to state that, for him at least, tape is
better. The point is why it's different. J

I was trying to moot that perhaps it's an issue of semantics.
It's probably
impossible ot say why. I would say that analogue sounds more "real". But there's every
chance, and probably almost a certainty that it's not as real while it's floating through
the air, just more real by the time our brain has interpreted this moving air.

My own take on this (as a musician - Jesus - don't ever listen to musicians) is that
digital is the truth, analogue is not the truth. Why do we need all the extra "warmth"?
Because the musicians are inadaquate and need it. That's why. Digital at 24 bits is the
real thing, you hear every nuance, you also hear everything that is crap. So only the
really great musicians survive.
So long live digital. All else is bullshit.

Of course you're right in that maybe nobody completely understands why things sound the
way they do, but in my experience it's all about distortion. The computer is bad at it,
and analogue is good at it. That's why the attack of compression in the computer doesn't
sound right...Because in analogue there are subtle distortions around that attack that
give the compression a sound. We might be able to measure that, but the computer can't
replicate it any more than it can sound like a console, a valve, a tape machine or a
guitar amp. Yeah of course it's WAAAY better than it was five years ago, and in five years
time it'll be way better again. But it's still weak. Take all these plug ins, Waves analog
buttons, the Slate Digital stuff etc, yes they sound quite good when you first listen to
them, but I think most of us have had that moment of disappointment when you take it all
off and the mix sounds better without. Analogue has this way of distorting without going
mushy that we still don't have in digital. When that nut is properly cracked, and of
course it may never be, then the perfection of digital will be tamed. IMO. J

That is very true. However, I'm one of those
who grew up on analogue - but I can see and hear that digital sound is an incredible
improvement on that awful wow and flutter (I have a keen sense of pitch) and all that mud
that anologue gives us. However, the musicians are rarely as good these days.

Yes people believe in the experts so much and are afraid to question them.
SOS will
prove it to you and they aren't arrogant, just a bit tetchy sometimes eh!
Hugh proved that an audio signal can still be deciphered by the ear by using one bit,
but noise will be a factor.
There's a compromise between Bit depth and sample rate
but we have a good standard today.
I agree with Ariosto that digital is king.

100% agree. I'm 46 years old. I grew up on
analogue, gradually moved to digital, recently brought analogue tape and desk back into my
set-up.
I'm going off-topic a bit here, but analogue recording sounds different
but not better. How can it sound better? It is more fun maybe, because of nostalgia
and having to work with its limitations (fewer tracks, bouncing, running out of tape,
cleaning the heads) and limitations tend to bring out the best in artistic endeavour. But
"sounding better" just because you are recording to tape? Nah.
Quote Ariosto:

musicians are rarely as good these days.
100% agree again, but I don't think it has much to do with analogue vs.
digital recording. Kids seem less willing or able to devote the time to practicing an
instrument than they did when I was their age. There are too may other ways to occupy
their time: the internet and video games being the two biggest time sinks. Also, the age
of superstardom for musicians is coming to an end, so maybe they aren't drawn to by the
awe and glory like we might have been, or are more attracted by the DJ route. Less live
venues doesn't help for those kids who do make it as far as performing. But that's
a different discussion.

I was floored to actually read the column--by now, it's clear to me that there's a certain
cohort of older fellows who simply hate digital, and are always pining for the good old
days of analog tape. Nothing is going to dissuade them from believing that the good old
days were the best, and that analog is being unfairly (though inevitably) thrown into the
trash. Fine. But to utter falsehoods is not fine. It's simply embarassing. Thanks to
Hugh Robjohns for clearing up (!) the strange technical notions of another aging
ranter.
P.S.: I think another thing that might be bothering the Doctor is the
democratization of music production. Fair enough. I'd agree that there's a lot of
hackers out there (I'm one of them) using cheap stuff to try to put their stuff out there,
or just trying to do really good with what they've got. But I'd never represent myself as
a pro--I thoroughly believe in professionalism myself, and I readily condemn the folks who
present themselves as pros in the audio profession. But the worm has turned, and we are
never going back to "the good old days," and that's that. I say full speed ahead.

+1,000,000
Let's open the debate.
As I see it there are 3, modern, analogue
'things':
Recording using multi-track tape This forces an artist,
especially a band, to record a certain way. Witness the recent Foo Fighters album where
the entire project was recorded in a garage, on tape, via analogue desks and outboard. It
actually became a promotional selling point for the album. The band must be good musicians
and well rehearsed because errors can't be "fixed in the mix". Editing has to be expertly
done with a razor blade. The equipment has to be expertly maintained. Et cetera. This
method of recording brings out the craftsman aspect of musicianship, studio engineering
and production. And a huge chunk of what makes studio personnel tick is respect for
craftsmanship.
Using analogue outboard (including software
emulations) This is when specific, characterful outboard is used to deliberately
affect the recorded sound. Analogue tape need not be involved at all. Tube compressors,
classic EQs, classic reverbs. This is really the search for something new resulting in
reaching back in time for something old; the realisation that, just because the previous
generation used it, doesn't mean it has been superseded.
Analogue Synths vs.
soft synths "My old Moog sounds waaaaaay better than your Arturia soft synth."
Yet again this is the search for something new (which originally began as the search for
something cheap) resulting in reaching back in time for something old.
Somehow these 3 analogue things have been conflated into 1 thing, namely that analogue
sounds better.
- Is it because it is more immediate to use? Knobs and sliders
versus mouse & click?
- Is it because it is easier to understand? Signal
levels nudging the red line versus digital dB overhead, floating point summing on virtual
mix busses, clock jitter, etc?
- Is it because it is associated with the
halcyon days of post-war music when bands and songs seemed less [ ****** ], and life in
general seemed less complicated?
Does the latest Foo Fighters album sound
better than the previous one? No. It sounds absolutely amazing, and definitely different
to the previous one, but not better.
Could Rob Swire manipulate the entire
audio frequency range to make Pendulum's trademark beefy sound by using tape and outboard
alone? Not a chance. He analyses each track's frequency curves in his DAW to make sure
everything has its place and room to breathe.
Only a pedant would argue that an
Arturia or GeForce soft synth doesn't sound authentic enough, especially in a mix, and
especially when the old duffers who used the originals are nowadays more than happy to
endorse and use the soft versions.
My personal situation is that I make music
using analogue synths (currently a Juno 6 and a Eurorack modular which has become the love
of my life). This is partly for nostalgia (I was too poor in the 80's to afford them),
partly for the sound but mostly for creativity and speed. My synths can't store presets so
I have to twiddle knobs instead of calling up familiar old sounds and using the same old
chops, and I have to record their sounds there and then and move on. I record using Apple
Logic for reasons that should be obvious. Sometimes I route my synths through a 1975 Akai
3-head reel-to-reel and back into Logic for that 'recorded to tape' sound. That's just for
fun, and looks as cool as f_ck in the corner of my studio, and it does make a difference
to the sound (and the noise floor!), but I also have tape plug-ins that sound exactly the
same.
So I guess I'm one of those older dudes who sees the analogue smorgasbord
for what it really is and cherry picks what he needs to get the best out of his pitiful
artistry.
Don't leave me hanging: RSVP.

Sounds about right, but I am not at all sure that analogue is any simpler then digital!
Sure, if you look at analogue in the same simple minded way that gives rise to
silly stairstep 'waveforms' in books for the hard of thinking about digital audio then
maybe it appears simpler, but having been there I am a LONG way from convinced that it
really is. You seldom see a scope cart in a studio these days, or even a
tentelometer, both of which were standard equipment back in the day.
When you
dig into the detail of how these things really work I think analogue is in some ways more
complicated then digital because digital allows many, many simplifying assumptions that
work most of the time (at least until you get right down to the physics), analogue has
simplifying assumptions that tend to hit the buffers rather sooner. Understand your tools, and know where the limits are, and you can get the result either
way, but for my money digital is usually faster for most things most of the time.
Regards, Dan.

There may be something to the analogue v. digital debate we haven't yet considered.
In essence, we live in a world that is "analogue", i.e. inconsistent, somewhat
unpredictable and in a never-ending state of flux. In the natural world, nothing can ever
be reproduced exactly, even one more time, let alone millions of times. This includes
sound. No instrument can be played identically again. Not a single note can be made to
sound exactly like the previous one. The physical, molecular properties of performer,
instrument and room do change irrevocably, moment by moment.
Maybe this is
what's weird about digital technology. Digital recordings, to me ears, typically sound
"locked in", as if they can't "breathe", as if the life of the original performances has
been sucked out of them. "Perfect", yet in a deadly way.
I remember, sitting
with a friend a while ago and listening to old vinyl records, mostly jazz but also 70s
pop. His stereo system was cheap junk, really, bought at some garage sale, and the
speakers were tiny. Yet, there I was, listing with amazement to the depth of the stereo
field. I was struck by the realism and excitement that came across in particular with the
way the bass was projected into the room we were sitting in. You could literally see the
performers with your mind's eye, and you could get a sense of the studio, too. The effect
was, as if a small version of the actual recording studio had been transported into the
listening space; as if we were witnessing a true representation of the original
performances.
This is what recorded music used to sound like (you can tell
I'm a bit older). Music used to regularly transport me into the middle of the recording
session. It was as if the band was right there in front of me. However, when I listen
to contemporary recordings, this never happens. By contrast, I feel as if I'm miles away
from the action, as if I'm not needed. My presence seems entirely superfluous. (Little
wonder, I haven't felt like buying an album for ages, not helped by the demise of good
songwriting and story telling in music).
Real life is not broken down into
digits, it is not ones and zeros. It is not quantised, dithered, processed and eventually
reconstituted from strings of numbers.
Perhaps this is what's fundamentally
wrong with digital media - it is alien to and separate from the natural world around it.
It never interacts with it. To the contrary, as we all know, it needs to function
perfectly and 100% identically each time, for it function at all. Errors in the digital
domain are unworkable and consequently unacceptable. So, we end up with sterile,
lifeless, non-interactive, forever unchangeable digital products that fail to reach us on
levels deeper than the most obvious (the same would be true for paintings v. computer
graphics, or film v. digital photography)
If this is true, I can't see how
digital could ever catch up with analogue, since it wont be possible. If we require the
medium to interact with us and the environment, to be moved on deeper emotional (let alone
spiritual) levels, digital technology will eventually be considered incompatible with
artistic expression.
Alternatively, man could adapt to technology, even
merge with it. This is a very real possibility, too.

I'm sorry, but to me it's as if you writing in a foreign language. Many people try to set
up some sort of division between science and technology on one hand and the natural,
artistic, "human" world on the other. I've never seen it myself. Science is a human
endeavour, just as art is a human endeavour. Much harm has come from trying to force them
apart (cf C. P. Snow's Two Cultures).
In the present discussion digitisation is
just a technique, no more and no less. Words like sterile and spiritual can be applied to
digital products and analogue products equally. What matters is the end result, not how
you got there.

Indeed.
However, if you try to understand the point I'm making, you'll see that digital technology
behaves very differently from more traditional, analogue ones, in particular when it comes
to capturing and reproducing real events.

Of course it does. But if you'll try to understand the point I'm making, that's
irrelevant. What's relevant is what the final product sounds like and that is down to how
the maker uses the techniques they have chosen to use, not on what the techniques are.
I dare say that on pottery forums there is endless debate about the merits of
different clays and glazes and whether to use gas fired or electric kilns, but as a viewer
all I am interested in is whether the pottery moves me.

In case anybody's wondering, I'm in no shape or form "anti-science", "anti-maths", or any
of the sort. I love technology. For a start, it allows me to publish my musings
worldwide, free and instantaneously. Fancy that.

In any case, how "analogue" is analogue in truth?
Tape is sampled at the bias
frequency. FM radio by the IF (ok, 10.7MHz but pulse counting discriminators were said to
give the lowest distortion and ran at about 200kHz IIRC?).
It could even be
argued that vinyl audio is sampled by the surface noise? That is what, a 13bit system. But
it all starts with tape.

I guess you could say analogue data is "sampled" on a molecular level, when you consider
audio tape or photographic film (ever noticed the incredible depth of field and realism in
old photographs, in spite of inferior lenses when compared with modern ones?). The
achievable resolution of analogue is finite, too.

Photography is a chemical process, tape recording is not. The
bias frequency must be at least twice the upper HF input (familiar?).Tape domains are not
"molecular" in size. And have you ever noticed the incredible amount of noise on old
recordings compared to modern ones?
