MusicTAP
talks with audio legend
Bob
Ludwig
|
Our
audio affiliate site, MusicTAP
recently had the pleasure of interviewing with the legendary Bob
Ludwig. For those of you who may not know Bob by name, suffice
it to say that if you've listened to music in the last 30 years,
you've definitely heard his work. It's no exaggerations to say
that Bob is one of the world's leading audio mastering
engineers. The list of titles and artists he's worked on and
with is WAY too long to go into here (but you'll get a sense of
some of it in the interview below). Bob is also the president of
his own company, Gateway Mastering. He graciously agreed to
answer a set of questions formulated by TAP
editor Matt Rowe, as well as staff writers Greg Warner and Grey
Cavitt.
We hope that you'll enjoy the insight that Bob's answers
provide into the world of mastering and the role that it plays
in delivering quality music. |

Bob Ludwig: Before I start
with these "re-mastering" questions, I wish to remind
readers that my main job is doing first-time original mastering of
projects that have never been released before! I work with the major
labels- Sony Music Entertainment, EMI Group, Universal Music Group,
Warner Brothers Music, BMG Entertainment etc. I'm lucky to be among
a select group of mastering people artists and producers turn to for
engineering the final creative step of their new music.
For me, the pressure of doing original mastering brings about a
hundred times more pressure than doing re-mastering of existing
catalog work. The accountability of deciding how a new-born
conception will be presented to the public for the first time is a
much heavier responsibility than addressing a project for
re-mastering that had already been approved by the Artist. Most
audiophile and other small record companies don't often use
first-run mastering engineers for catalog re-mastering because we
are, of necessity, too expensive to hire.
While the competition between us is intense, all the top first-run
people know each other and we all consider ourselves friends. We
often help each other, sharing hard won knowledge about some piece
of gear, or even swapping lacquers when a batch was discovered to be
bad etc. We enjoy a high degree of professional ethics. Bad mouthing
of other engineers or gear is kept to a verbal minimum and almost
never in print. We make our living from state-of-the-art gear and
manufacturers often turn to this group for evaluation before
releasing something to the public. Professional mastering engineers
are the keepers of the artist's secrets. Seldom do we reveal what we
are about to work on without the record companies' permission.
MusicTAP: There are many
people, and I mean many people, that do not know or understand the
difference in sound other than does a re-master sound cleaner,
punchier. How would you explain to people the differences in order
to give them the ability to notice for themselves the improvements?
Bob Ludwig: To me there is no "rule"
that a re-mastering sounds "cleaner and punchier" or even
better than the original. There are so many factors, mostly, who is
involved with the re-mastering? What tapes were available?
There are several box sets out that are so poorly done, I could
site lots of examples that can show this, but of course I never
would.
So, to get back to the assumption that re-masterings always sound
better, when they do, the quality of Analog to Digital converters
has improved in the past 7 years or so thus, all things being equal,
projects can be re-done with better fidelity now. Also, the
availability of digital gear that runs at higher sampling rates and
wider bit depths keep the rest of the post production stream more
audiophile.
The only way to notice for yourself the difference in an original
recording and the re-issue of it is to play both side by side and
hear the differences.
MusicTAP: We're in an era
where re-masters arrive by the boatload from whatever label's ship
that has just arrived in the harbour brings to us. The problem is
that, as consumers, we are unable to differentiate what was the "original"
sound as recorded in the studio vs. new reissues of the same songs.
They sound cleaner but are they representative of the actual
masters?
Bob Ludwig: It's often hard to
tell. I just bought the SACD of one of my most favorite recordings
that I have heard since my childhood, Billy Holiday's Lady
in Satin. I put on the disc and my heart was broken, I
got none of the chills I used to get. I put on my old LP and the
chills were back! I noticed the LP was much slower than the new
re-mastering. So, only the people involved know which is "right",
but to me, the new version totally lost the magic, even if the new
speed can be shown to be "correct"... so what!
On the other hand, The Stones' Beggars
Banquet can be shown to now be at the same speed the
original Rosetta Stone singles
were and that the original EQ'd and compressed production masters
were at fault. The album sounds SO much better to me now. So it can
go both ways.
MusicTAP: Obviously, what was
recorded in the studio by the original band is what was recorded.
What guarantees do consumers have that remixed product doesn't have
the 'stamp' of the remixing team; that the re-mastered product is
not the audio vision of the team rather than what actually came off
the master tapes.
Bob Ludwig: There are only
guarantees when it says the artist were involved, otherwise, who
knows! Remixing can be dangerous, the older and fewer tracks, the
less dangerous. Sony's mixing Kind of
Blue or my mix (and mastering) of the new Patsy Kline
hits on MCA I did from the original 3-track masters one can't go too
far wrong. One removes a whole generation of tape hiss and
distortion this way. 8 track? Much more room to go wrong... 24
track? Almost impossible to duplicate the original in many cases.
Some cases like Tommy which
was remixed from the original 8-track (and I got to re-master it
several years ago), Pete Townshend told John Astley, one of the
remix engineers, that he wishes it had always sounded that way. The
Fleetwood Mac surround DVD-A I mastered with Ken Callait had some
new parts added, BUT they were parts the group had always wanted to
hear but there was no room on the stereo mix. Perfect!
If the artists are not involved, indeed, the re-mastered version
may not be the artist's vision. Often budgets don't allow such
participation.
MusicTAP: Why re-master at
all? What has new technology brought to us that gives the ability to
make a better original?
Bob Ludwig: Speaking for
myself, when I started my own business, Gateway Mastering & DVD,
I was finally able to have what I think is the ultimate new
technology, a great acoustic, a listening room with what are, to me,
the world's best and most accurate speakers, my unique serial #1 and
#2 Eggleston Works "Ivy" speakers (check their web site
for information). I use bridged Cello Performance Mark II amplifiers
capable of producing something like 3,000 watt peaks. I use the new
utterly amazing Transparent Audio Opus MM Speaker cables and even my
patch cords are made using Transparent Audio cable. Listening in my
room is a dream and it is often easy as pie to hear an older project
and know what to correct immediately.
The other main technology is intense investigation of superior
analog tape machine playback. We have ¼", ½" and
1" stereo machines with Ampex Class-A electronics, Aria
Discrete Class-A electronics and Tim DeParavicini's Esoteric Audio
Research tube electronics and a set of Cello tape electronics as
well. Choosing the best electronics for the particular job can often
get you half way to your destination before moving a knob.
MusicTAP: What is your
history? In other words, what started your career in re-mastering
and how did you get to where you are now? A small biographical
sketch.
Bob Ludwig: I am first a
musician. I have a Bachelor's and a Master of Music degree from the
Eastman School of Music in Rochester, NY. While at Eastman, I was an
announcer at a local classical commercial radio station and I was
also the Principal Trumpet player with the Utica Symphony Orchestra.
I was also in the school's recording dept. and recorded countless
recitals and large concerts. I freelanced for Century Records and
recorded many local school concerts through-out Western New York
State. While finishing up my Masters degree, Phil Ramone (then
unbelievable engineer and now famous producer of Paul Simon, Billy
Joel, Chicago, Barbra Streisand etc, etc.) came up to teach the
first recording workshop at Eastman. I was his de-facto assistant. I
left Rochester to work with Phil at A&R Recording in NY. I was
an assistant engineer and, while there, I learned the art of disk
cutting and mastering. Phil was my mentor, I couldn't have had a
luckier start in my career. Every engineer there spent some time
learning to cut disks as it was felt that one couldn't be a good mix
engineer if one didn't understand the limitations of disk cutting.
When I got to that part of my training I immediately enjoyed it and
starting attracting clientele from outside the regular studio work.
I could read scores and thus attracted classical companies like
Nonesuch Records, one of my oldest and much loved client.
There was a new acetate disk cutterhead developed by Mr. Georg
Neumann, the SX-68. The sound improvement from this new cutterhead
was like going from 7.5 ips to 30 ips tape. There was a new company
opening up in NY that not only would be the first company to have
this new head but they also had fantastic European Studer and
Telefunken tape machine which were far ahead of the Ampex 440
machines of the time in tape handling and speed stability. This
company was named Sterling Sound and I left A&R to become their
first employee and, later on, Vice President of the company. Even
though it was early in my career, I was already doing most all of
Nonesuch's catalog. On the pop side, I was doing the original
mastering on Led Zeppelin II,
Houses of the Holy, Jimi
Hendrix, Janis Joplin, Peter, Paul & Mary, The Band, and lots of
other great stuff.
Every mastering engineer worth their salt has always done re-issues
of older works. I did all of Eric Clapton's Derek
and the Dominoes albums once, They have probably been
done 10 times since!
MusicTAP: How did you come to
start Gateway Mastering & DVD? What factors encouraged you start
your own mastering facility?
Bob Ludwig: When I was Vice
President of Sterling Sound many people thought I owned it. When I
worked at Masterdisk many people thought it was all mine. I was just
an employee at both facilities. I have always wanted the ultimate
sound environment and have the very best equipment. Most big
mastering facilities are places with 5 or more engineers, every time
an expensive piece of gear comes out all 5 engineers want it and it
is often too expensive for management to buy it for everyone, so
nobody gets one! By starting my own company the buck stops with me.
I can build the best room I wish and get all the gear I think is
best without being beholden to anyone else.
The biggest factor for starting my own business was my reputation
in the industry. When one goes to the bankers for a huge loan, they
want to see contracts, yet, independent mastering engineers never
have contracts with anyone, it is always "what was your last
hit"? Fortunately, my track record was enough for financing. Go
to www.allmusic.com
and search for Bob Ludwig under "artist" for a very
partial discography. None of my records from before 1972 seem to be
on this list (Led Zeppelin, AC/DC's Back
in Black, the early The Band records, Sly and the Family
Stone etc.) Search also under Robert Ludwig and Robert C. Ludwig
(most of the Nonesuch and New World Records classical credit me with
my proper name!).
MusicTAP: The recent
re-masters for The Police were wonderful to my ears. However, the
later albums for The Police, and I'm talking the chronological
order, seems to benefit a little less than the earlier (the first
two albums) issues. It's my feeling that there was a lot less going
on in the first two albums than there is in the remaining catalogue.
Is that an assessment that you would agree with? If so, why would
that be?
Bob Ludwig: I agree with you.
The reason the recent albums don't experience as much improvement is
that Hugh Padgham mixed them and he did near-perfect mixes! What's
to fix?
MusicTAP: You've re-mastered
the Essential Leonard Cohen.
My, and many others', love for LC is as heart rending as his lyrical
output is. Your re-masters deepened the underlying 'darkness' of his
music. Do you have to prepare to re-master a certain disc,
especially one so full of tonal qualities like Leonard Cohen?
Bob Ludwig: With my schedule I
never get to prepare! I walk in the studio and do whatever comes in
the door right then and there. Leonard was totally involved with the
Essential LC and guarded his precious sound from being anything
other than what he wanted. I love Leonard, he is one of my favorite
artists.
MusicTAP: What was your most
challenging project?
Bob Ludwig: When I originally
cut the masters for the second Band album (Up
on Cripple Creek etc.), the vinyl of their first album
had all the low bass cut-off as it was done by a union cutting
engineer at Capitol in NY. The Band's sound IS that low, huge sound.
It was almost impossible to cut moderately loud and still keep the
bass without skipping. In fact, I think on some cheap turntables
some of them DID skip anyway!!
The Velvet Underground masters were hard to do, they were sometimes
so raw.
MusicTAP: Which project in
your career was your most satisfying? One that gave you the most
'bang for your buck', one that you're most proud of?
Bob Ludwig: Many come to mind,
all equally favorites:
Reference discs for Music from Big Pink
The rest of the early Band albums especially the second one (I
didn't get any credit, as was the norm, until the Moondog
Matinee vinyl came out).
Dire Straits' Brother's in Arms
which almost single handedly established the new CD format.
The second Led Zeppelin album and Houses
of the Holy
Jimi Hendrix: The Cry of Love
and Band of Gypsys
All of Bruce Springsteen's records, especially Born
in the USA which was the first commercially released
compact disc that was manufactured in America!
Nirvana
Bryan Ferry's entire output
Hall and Oates entire output
Almost all of Rush's entire output.
Any of the Eric Clapton records I did.
ZZ Top's unbelievable records like Deguello
Lou Reed's records
Many of the famous Nonesuch Records Explorer
Series of amazing world-music.
The Rolling Stones re-issues on Hybrid SACD
Sly and the Family Stone There's a Riot
Goin' On (Family Affair,
etc).
I could go on and on...
MusicTAP: Is there a work out
there that you'd love to revisit? By that I mean, is there material
out there that you'd love to re-master?
Bob Ludwig: Yes, all of Sly
Stone's work and Prince's early albums.
MusicTAP: What was working
with Phil Ramone like?
Bob Ludwig: Phil was my
mentor, and he in turn was influenced by Tom Dowd; both men are pure
genius. His A&R (Arnold and Ramone) Recording Studios was the
cream of the independent studios in NYC at the end of the 1960's.
Nothing could touch them back then. He had the best engineers and
the best maintenance people. They all own their own businesses now.
I'm on an advisory board with Phil for NARAS, I just love hearing
him talk, about anything!!
MusicTAP: What is the usual
process from when Gateway is contacted for a project to the final
release?
Bob Ludwig: Someone calls us
and schedules a day I can work on their record. Either I do it
alone, or the producer and sometimes, artists attends. The day
arrives, I listen to their raw tape and hear in my head how I think
it could sound. I turn the knobs on the right gear to make it sound
like I hear it in my head. I master it, discuss if any remixing
needs to be done and do any further editing that needs to be done.
When the artist, producer, A&R person and the manager all agree
I have gotten as much musicality out of their original master tape
as possible, the approved master is copied to the appropriate medium
desired by the plant (PCM 1630, exabyte DDP tape, Pre-master CD-R,
or Yellow Book CD-ROM.) The actual parts going to the plant are
quality controlled from top to bottom by one of my engineers,
usually with headphones to catch problems one can't hear in
speakers, and notes are made of any abnormal sounds that are in fact
approved.
On very rare occasions the artists may ask me to approve the final
CD pressing (they can sound quite bad or match what we have given
them) which I may do.
MusicTAP: Gateway Mastering
and you have been at the cutting edge of high resolution mastering
in the digital format for years. Do you still feel on that edge, and
if so, what from that special view do you see approaching?
Bob Ludwig: Absolutely on the
edge! I was one of the first to have Tim DeParavicini's 1" wide
stereo tape machines (I already have had my first Number One hit
with the 1" machine, Creed's single With
Arms Wide Open was mixed to 1". As wide as ½"
sounds, 1" sounds wider! I have the ATR Services "Aria"
pure discreet Class A solid state tape amplifiers as well. I am also
the first to own the ATR Services 2" eight track with an extra
time code track for doing surround sound from analog mixes. I just
purchased a state-of-the-art 8 channel surround console with 120
volt rails on it from Sound Performance Laboratories in Germany. In
the digital domain, the gear is finally starting to catch-up to the
promise high resolution digital brought to us. It has been ten years
since I bought one of the first 96kHz/24 bit converters from dCS in
the UK. There was a while when I had serial #1 of some of their
gear. I once had a 192kHz converter where the only thing I could do
with it was play it back through another 192kHz converter! There was
no means of easily storing it for a while.
MusicTAP: Do you typically get
involved with surround or stereo remixing, or do you focus on the
mastering?
Bob Ludwig: I have mastered
over 100 surround sound projects. The only mixing I do is on special
occasions like Patsy Klein or re-balancing stems, I once mixed a
Mariah Carey vocal, but all that is rare, I have plenty to do with
just mastering!
MusicTAP: What are your
feelings about the various sound formats that you have worked with
over the years, and what do you specifically think about the new
high-resolution formats?
Bob Ludwig: Analog tape has
always sounded wonderful. Vinyl disk is a medium our ear really
loves, a good vinyl turntable and phono preamp is a very musical
thing. When digital was first introduced in the 1970's before the CD
was invented, I initially loved the sound of it. I got to work with
some amazing sounding early digital recordings like Donald Fagen's
The Nightfly, Rush's Moving
Pictures, The Police's Synchronicity.
No hiss and 100% speed stability, for the first time, on classical
piano. I loved it. The 3M digital and Soundstream digital machines
sounded very good. Then when CD players came out I got bothered,
like a lot of other people, with the brittleness and lack of echo
detail and soundstage that characterized "bad" digital
sound. It certainly wasn't "Perfect Sound Forever" as was
advertised! As our ears got better and gear got better I pushed for
engineers to stop using 16 bits DATs and move up to 88.2kHz or even
192kHz/24 bit recordings. The final result is definitely better. Now
I love the new high resolution digital formats. Finally, the high
resolution digital is always better than analog from a technical
specification and, while not always, it can even sound better to our
ears. I'm still a great believer in the use of tube gear and analog!
MusicTAP: This question is for
the benefit of newcomers to SACD. What is DSD, and what are the
benefits of it?
Bob Ludwig: Direct Stream
Digital is an updated version of an old technology Sigma-Delta
conversion process that dbx used in the late 1970's. Instead of
sampling the sound at 96kHz per second with a 24 bit wide word, DSD,
the present system, is a one bit sample but done at over 2.8
Megahertz per second. The benefits are that it is considered a
direct replacement for the CD with surround sound added. No video
screens (or no extra added value for some minds), put it in the
player, press play and music comes out! It can have the added
advantage right now of having a hybrid layer that is near 100%
compatible with all existing CD players.
MusicTAP: What are the
advantages to a floating control room?
Bob Ludwig: The floating floor
keeps the sounds in the two mastering studios we have from
interfering with each other and the outside world. It can reduce
airborne noise and especially impact noises.
MusicTAP: How much freedom do
you usually have with projects?
Bob Ludwig: It's the Artist's
record so I do everything possible to restrict my freedom to bring
our their vision of their music. Having said that, people use
first-run mastering people like Stephen Marcussen, Doug Sax, Ted
Jensen, Greg Calbi, George Marino, Tony Dawsey etc. because of their
reputation. People know that these people can often bring out
musical elements hidden in the mixes that the producers would never
have thought possible. They are worth the extra money when your
project will be competing with all the other records out there. We
are all here to serve the producer/artist and the music. If they
want it mastered backwards, we will be happy to do it. The producers
use our "take" on it as a great starting point.
MusicTAP: What are the
different challenges in working with older master tapes compared to
newer ones? How do you feel about the quality of the older versus
the newer tapes, and how does that affect your mastering approaches?
Bob Ludwig: Many of the analog
tapes from the 1970s-1990s didn't age well as the lubricant doesn't
last a long time. These tapes will gum up the heads so badly that
they will actually come to a halt and not pass through the machine!
There is a method of baking the old tapes that literally brings them
back to life, although sometimes it does increase the print-through
all analog tapes experience where the sound of one layer of the tape
is superimposed on the next layer of the wound tape. The Rolling
Stones ABKCO tapes were sufficiently old to not suffer from any of
these problems and did not need any baking. They were in terrific
physical shape. Some of the analog Police tapes did need some baking
to restore them. Really old tapes like the Agfa 555 or 525 and BASF
tapes play as though they were recorded yesterday. None of this
affects my mastering approach.
MusicTAP: How much equalizing
do you typically have to employ, and what is its role in bringing
out the sound of a master tape?
Bob Ludwig: Equalizing is one
of the prime tools of a mastering engineer. The idea is always to
make everything sound as musical as possible. Like analog tape
machines, I have many different equalizers, each on "state-of-the-art"
in it's own way, yet they all sound different which is why I own so
many. In the analog world, the tube Manley "Massive Passive"
equalizer can create a beautiful over-all color for a recording. The
GML (Massenburg Labs) equalizer can do surgical, precise equalizing
without making any kind of sonic signature. Others like the Avalon
have very musical EQ curves and the Millennia Media has the ability
to operate either in solid state or as a tube eq. In the digital
domain, George Massenburg also makes a wonderful digital equalizer.
Daniel Weiss has a special "linear phase" digital
equalizer quite unlike anything else. Equalizers can make dull tapes
sound normal, they can make bright tapes sound normal, whatever it
takes. Use of them varies from nothing (if it doesn't need it and
already sounds good) to amazing amounts, totally depending on the
circumstances.
MusicTAP: What do you think of
"pro-sumer" mixing and mastering software packages such as
SoundForge, Bias PEAK or Bias Deck, et al?
Bob Ludwig: I'm not aware of
anything ever coming into me on those formats, so no thoughts.
MusicTAP: How has Pro Tools
changed your methods, and what are your thoughts about it? Do you
even use it?
Bob Ludwig: We have 8
different brands of professional workstations at Gateway Mastering &
DVD. We receive material on all of them from time to time. ProTools
is the most ubiquitous of them all. About 60-70% of the projects we
do come in on analog tape. Of those that come in on digital, the
vast majority come in on ProTools as a source. The new ProTools HD
which can operate at 192kHz is fantastic for multi-track work, but
not as perfect as a mastering tool. Producers sometimes bring in
music mixed to "stems" with vocals (with all effects and
reverb) on one or two channels, background vocals on another pair,
then the instrumental track on yet another pair and occasionally
certain important instruments may be isolated. This way, if there is
a problem with the vocal levels it can be corrected right there in
mastering by remixing it!
MusicTAP: Were you pleased
with the Rolling Stones reissues and the reactions, both
commercially and critically, to them?
Bob Ludwig: Jody Klein, the
Senior Vice-President of ABKCO who was responsible for the project
and the rest of the team, Teri Landi from ABKCO, Steve Rosenthal
from the Magic Shop and the other transfer engineers in the UK were
all thrilled. I have had many people come up to me and tell me that
these records have made them listen to music again. What they mean
is, as professionals, we hear a lot of music but seldom get a chance
to kick-back and put something on and just listen for enjoyment!!
This was about the highest compliment I could ever receive. As you
probably know, even one title like Hot
Rocks outsold every other SACD and DVD-Audio disc ever
made combined!!
MusicTAP: Why did you choose
the controversial option of converting The Rolling Stones master
tapes to PCM for editing before transferring them to DSD? What were
the benefits and the drawbacks?
Bob Ludwig: I did not choose a
thing, I had zero to do with that decision.
ABKCO had embarked on an archiving program of their master tapes to
DSD. When they decided to do the Stones re-mastered set they decided
to send me masters that were already quality controlled for no
drop-outs, no sticky splices, best source, etc. etc. It took about 4
months of fitting it into my schedule as it was, if I had be given
the analog sources, which I would have been glad to work with, it
would have been intolerably expensive and much longer. I was pleased
to work with the SACD tapes, it kept me much more fresh for the
important creative work and not bog me down with the physical
decisions. With the Meitner converters on the most high resolution
monitoring system one can not reliably pick the master vs. the copy.
MusicTAP: Did you choose the
same route with the Police discs?
Bob Ludwig: Universal asked me
if I would prefer working from the original tapes and of course I
said yes. This was not a vast catalog situation. I was supplied
original analog tapes and digital tapes of those albums recorded to
digital. I insisted that they check for any analog sources that
might have been made at the same time as the digital sources. They
found them but I discovered the analog tapes were made as backups
from the digital masters, so there was no extra resolution on them,
only hiss!
MusicTAP: Is there any truth
to the rumors that the Stones re-masters would be pressed to vinyl
from analog tapes, or were those bootleg projects and rumors?
Bob Ludwig: Sorry, I can't
speak about any projects my clients have not announced to the
public. I am much too busy to be reading most internet newsgroups.
The few times I started reading some of the Stones comments, I
stopped as the people writing them didn't have a clue what they were
talking about. Plus, I found many of these people don't actually
like the music, they just like to collect and talk about minutia.
MusicTAP: Can you drop hints
about any future re-mastering jobs under way?
Bob Ludwig: No, it is my
policy not to discuss anything my clients do not announce.
MusicTAP: You have done a
marvelous job introducing Steely Dan to the CD era. Might you repeat
the job with SACD?
Bob Ludwig: The very first
surround project I mastered was the DTS CD release of Gaucho.
Universal has recently announced that Gaucho
will soon be released on SACD. Warner has already released Donald
Fagen's The Nightfly on
DVD-Audio this past December. Elliot Scheiner mixed both albums
originally and I mastered both originally. It is great to have the
original team together again for the SACD and DVD-Audio versions.
They sound totally amazing thanks to Elliot Scheiner's fantastic
mixing, there wasn't much for me to do.
MusicTAP: Today's bands going
into the studio have the ability to create their material using the
highest quality means available to them. Will this potentially
negate the need for re-mastering in the future, say 30 years from
now?
Bob Ludwig: Could be once the
DVD-Video, DVD-Audio and SACD surround sound is omnipresent, people
may not be interested in further speaker expansion. Perhaps in 30
years it will be broadcast directly into our heads and will need
re-mastering for yet another format to come!
MusicTAP: What might upcoming
technology add to 50/60 year old masters? Let's say for the fun of
it, Who's Next 30 years from
now.
Bob Ludwig: Noise reduction
that is ever more effective with less negative effects. Equalizers
that are tuned to a musical scale and can actually follow an
instrument playing through the scales, allowing the mastering
engineer to almost "remix" the problems in the master
tapes.
MusicTAP: How closely do you
work with the artist? I'm assuming that the bigger the artist, the
more involvement they may want. Or does the Producer generally just
hand off the final mix and say 'go to it'? What might a set of
guidelines be, for example?
Bob Ludwig: Usually Producers
attend sessions, and if the artist is also a producer or co-producer
they come. A big percentage of my sessions are client attended. I
like having the person who can make a decision right there in the
spot. We certainly so a lot of session work these days via the
internet sending massive files over the net for quality checking
around the world.
Almost always, there are notes from the Producer or we have a phone
call for as long as we need to be on the same page. They depend on
my musical skills to maximize the musicality inherent in their
tapes.
MusicTAP: What is your spin on
the analog vs digital argument? When you hear amateur audiophiles
rattling about the 'warmth of vinyl' and the 'brittleness or
flatness' of digital, do you feel that so much smoke is being blown
about nothing or is there validity?
Bob Ludwig: Early digital
devices could sound pretty good (Soundstream digital, 3M 32 track
multi-track and 4-track) or pretty bad (average consumer CD player).
The explosion of CD caused great research in the digital-to-analog
conversion process, but there were only a handful of professional
machines actually recording thus less research in the
analog-to-digital conversion process.. Finally, in the mid-80's the
quality of the ultra-critical analog-to-digital converters started
happening. Designers finally found that digital could be so
accurate, the slightest error in the ANALOG part of the design was
easily heard! Now, a great converter takes as much care with the
analog circuitry as the digital. With high resolution digital, it is
almost impossible to pick out the original from the copy, while with
vinyl, one can ALWAYS pick out the original vs the vinyl playback!
MusicTAP: What would you say
to people considering what you do as a career? What would be a
logical progression?
Bob Ludwig: First, be a
musician! It is a apparently a very difficult thing to be a
successful mastering engineer, if you look at the mastering credits
on big selling commercial CD releases you will see the same names
now as one did 10 or even 20 years ago. It is a very small group of
people on the "A" list. I think I have the best job in the
world (although the long hours are not great!)
MusicTAP: What do you see
beyond SACD/DVD-A/XRCD? What do you envision as being a new update
(if you were creating one) to the reproduction of music in the next
10 years? 20 years?
Bob Ludwig: The Blu-Ray disc
has already been announced, and I look forward to this even newer
technology that was announced a year ago!
MusicTAP: Bob, thanks for this
wonderful opportunity to help the consumer to understand a little
more about the process. We know that you're very busy and really
appreciate your taking some time out here.
Bob Ludwig: You are welcome!
