Last Manufacturer of Pro Analog Audio Tape Closes 550

goosman writes "Quantegy, the last manufacturer of professional reel-to-reel analog audio tape in the world has closed their plant in Opelika, AL leaving a reported 250 workers without jobs, according to the Opelika-Auburn News. Emtec (the former BASF, which used to be AGFA) was the last European manufacturer and ceased manufacuring in 2002. An audio account of the closing can be heard at NPR."

    Seriously, Quantegy was the last munufacturer of the 2" analog reel-to-reel tape that is used in high-end recording studios. And of the 1/2" tape used for analog mastering.

    A dark day for those of us who loved the old analog sound.

    That's the kicker. Analogue tape can produce a certain sound which producers sometimes love. It's not about the accuracy.
    Having said this it can't be long before some manufacturer brings out a piece of software that can mimic the sound of analogue tape...

    If there is a market for 1/4", Maxell will reintroduce XL. Or some Chinese plant will start making it.

    Pro tape, especially 2", is staggeringly expensive. And it still offers some qualities of sound which take a significant effort to duplicate with digital. Yes, this is aberration, but it's a desirable *analog* aberration, and studios that use tape contribute sort of a gestalt to the overall product, an organic quality.

    I'm a big fan of digital, and I don't really care about analog tape, but I do sympathize with the folks still using 1" and 2" decks.

    Digital recording is only *just now* getting to the point where it can truly take over. (It's been there for playback for decades, sure, but production is another story.)

    But it's always been expensive to do 2". In the day, we'd get tapes that had been used once in a voiceover studio and bulk erase them.

    Oh well... I feel sorry for the plant workers and anybody still using an ampex console. Somewhere I think i still have a Teac 4-track 1/4", and boxes of unused, or only partly used, tapes. Ebay time?

    Now that there are so many digital recording formats, with various numbers of tracks, it is essentially impossible to create legacy recordings. Many programs we use today won't even run in 5 years let alone 100 and all we will have is basic 2 track mixdown masters of many records.

    With tape you could use whatever you wanted to record a record, it all got put to the same tape and in most cases the tape lasted a very long time, 50 years plus. Better yet, often times the recording equipment was better than the tape playback so as time went on you could get better sound off the same tape because technology had advanced. Digital is locked in stone forever, never to reveal any improvements. Even as a crude 2nd step backup there is the potential to bounce your multi-track masters to multi-track tape for preservation.

    one of my friends is a huge analog fan when it comes to his music making, all analog equipment, especially when it comes to sound processing and such, and he refuses to use computers in the process, but even he now uses a hard drive based 16-track recorder with a cd writer in it...previously he used a 4-track analog tape recorder.

    analog can be of high quality, particularly when it comes to balanced signals and such for all your inputs...but analog reel to reel? I can definitely see why that's going.

    First you got digital tape, of course DAT would be the most well known (at least it's the one I know) and while I doubt it can fill all the niches (particularly when it comes to multi-track recording) it can fill many.

    That's not to mention a 24bit/96khz sound card can be had for mighty cheap these days...of course if you need one with 10 inputs it'll cost a bit more. This kind of technology can probably fill much of the demand for multi-track reel to reel recording...still change is never easy, especially when you're talking about hundreds of recording studios who probably use the stuff still...

    I wouldn't be surprised if much of the cost of the upgrade would be negated by the fact you don't have to spend cash on tape all the time. Plus once it's in a digital format you can literally put it on anything, CD, DVD, tape, raid array, what not, and not have to worry about loss...of course this is assuming you're writing it on there uncompressed, or losslessly compressed.

    farewell analog tape...

    I have a really tough time believing that all of the analog tape ('pro gear' type, as measured in inches...ha) is going to be gone soon.

    As an 'audio guy' I have encountered so many 'analog heads' that I think for the wound-up-no-clue-audiophile-asshole market alone this would be worth somebodies while to maintain.

    ...I only wish I could be one of them. Analog recording offers so many advantages (read: quirks) to the producer/recordist...and not to mention the highest bandwidth available in analog audio media.

    Once again, before I ramble too far off topic... I don't believe it. There are far too many studios run by far too many producers which insist--for one reason or another (read: valid or not)--insist on nothing but analog...high quality analog....1" reels, 2" reels...1/2" reels....for mixdown, for final masters...etc. I simply do not believe it. Too many 'big name studios' operate with this techonlogy as the centerpiece of their of hundreds of thousands of dollars worth of equipment. There's something to think about.

    While I am continually saddened at the migration away for more sturdy analog ancestors of our current-day digital equipment, I simply do not believe that such a market--small but used to paying top-$$$ for everything....even tape--would be abandon outright.

    Reel-to-reel with a fat bandwidth (that you can actually measure with a ruler), and high inch-per-second rate is currently unbeatable in dynamic range and frequency response.

    As the proud owner of 2 brands of 24/96 cards (the good ones...or I would have 'settled' for a much cheaper 24/192 card--you know who I'm talking about) I can honestly say that analog--even my limited 1/4" experiences--is far more flexible with signal, has far more 'air' to it--a sound guy term for something we can't quite describe...try if you must--can handle a steading hammering greatly in excess of +0db...and all you get is a nice saturation....natural compression practically....try that with digital.......I can honestly say that if this is indeed the truth, I'm not only dismayed but horrified.

    Digital--no matter how sophisticated...no matter how high the sampling rate, no matter how deep the bits--is no comparison for super-highend analog tape.

    ...while you can pick up a 'good enough' or 'way beyond good enough' audio card for reasonable money--and 'pro gear spec' for much more money--it's damn impossible to get the same recording characteristics in digital.

    Don't get me wrong, I've always 'done it digital', for nearly 13 years now...except for the 'accessible' (Read: affordable) analog tape I've had access to....which even then was shown to be far easier to work with....but...good god.....no more 2" tape!????? anywhere!??!?!?

    If this is actually true--and I have many doubts that it is--well, then, this truely shows modern day mankind's ignorance...that, and savvy...in economic endeavors on "economy scale".

    I don't know whether to 'tsk' at those who believe it, or the fact--if it is indeed true.

    This is true only in an optimal sense. In a very real and practical sense, it's not true at all. Many tapes are stored in only moderately optimal facilities, and a lot are stored in attics, sheds, and basements. A major scourge is the "Sticky shed" syndrome as described here [geocities.com], for example. while the old Ampex tapes were major culprits, in my own personal experience I have seen a large number and variety of tapes suffer similar fates.

    Several months ago I had to resurrect a number of video tapes that had a similar problem. In short: tape is not as archival as vinyl. The question of archival quality audio reproduction is a hot topic being debated in library science. AFAIK, there have been no real concrete conclusions to the problem. From what I can gather, it seems very likely that the 21st century will simply disappear from history.

    I hope that's not true, but there are an awful lot of extremely obvious and seemingly implacable problems facing archival audio and video storage.

    While you have one very valid point that I can't argue--that digital audio will one day be 'nearly seamless'...and 'just about perfect'....it will have seams.

    I agree that one day--soon, at that--analog will be dwarfed in every way by what we do in the digital realm....it still won't be the same an equivalent analog counterpart...I'll let you choose what determines 'counterpart'

    Analog is a continuous wave....digital is not. Period. Aside from the idiosynchrosies that make analog a great medium (creative) to work in, digital has that one drawback.

    My point: For the love of God, man, do not confuse 'quality' with 'expense based level of accessability'.

    To get an 'audiophile quality' analog reproduction you need to have the higest in quality--and highest in price--equipment. For digital the entry level is much lower.

    My example: a $39 portable CD player (Via its line out) will have roughly the same (if not damn near identicle) quality output as a $1200 CD player....THD and frequency response being more limited by the output circuitry than any pickup circuitry.

    it'd take (Est.) roughly $5000 worth of analog gear...(being just the turntable and tone arm) to reproduce that.

    Take the high-end of analog audio....store bought vinyl reproducing ~60kHz signal, versus the high end of digital....DVD audio reproducing ~48kHz of signal...that's just the frequency...the real knock-out punch comes from the amplitude. The practically infinite variations between levels. As opposed to digital where it's quite tightly restricted. 16-bit audio (CD) does 65k discreet levels of amplitude....24-bit does 16.7mil. Quite a bit, yes....but, nowhere near par for reality, or even 'reference super-high-end-analog'

    Yes, digital high-end is far more (economically) accesible...but analog high-end is far more 'real'....'hiss' aside ;)

    Where I'm going with all this: I am not going to run 2" tape to listen to the latest album by my favorite band....but I want the studio that records them to. I want that level of 'actual perfect' to exist in some form and to be one day accessible...even if for nothing more than being able to either archive it digitally (using the real top-shelf digital technology for later down-sampling to the lowest-common-denominator of digital playback tech)...or for actual remasterability in later years.

    Remember: In the analog world, you CAN turn things up and down...in digital, all of it is artificial.

    mod parent up.

    Sure, my 96/24 pro-spec audio cards can record almost as well as my Tascam 4-track--think about that for a second--but, where is the cutoff and how sharp is the curve? (audio nerd joke)

    I mean it in all seriousness....The 'as-good-as-it-can-possibly-get' analog technology stomps and huge hole in the 'as-good-as-it-can-possibly-get' digital technology. Period.

    The second digital recording can accurately (read: perfectly) model the infinite level of amplitudinal variance granted to us by the analog domain...then I'll digress on this point. Even as a '95% digital' audio producer....and even then, I'm sure higher tape speeds and tape width would be an easy fix to stomp a hole in the digital champion.

    It can end up being an infinite race to higher sampling frequencies.... (remember your nyquist in digital, half of the top sampling rate is your actual top end frequency...and lets not forget about filter rolloff....22k tops for good cards, in reality...fuck the spec sheet)

    ...but you'll never beat that infinitely variable and infinitely dividable quality of analog.

    Oh, one more thing:

    > Next time you go to the record store notice how many High Resolution
    > DVD-Audio recordings are [being mastered from tapes].

    You could have saved yourself the bit in brackets, because that's about where SACD and its competitor are. For audio purists at least, the sad fact is that the CD is the cat's meow to the VAST MAJORITY of people, and the remaining dissenters just aren't enough of a market. I doubt higher quality audio will make much inroads in the future except in niche markets. Yes, the CD will be displaced, but it will give way to medium agnosticity rather than higher quality. IOW, people will be buying music in all shapes and forms (increasingly online), the CD will be just one of the formats, and of ever decreasing importance.

    Then again, maybe this trend will indeed facilitate higher quality audio. Since the software won't be bound to a particular medium anymore, new formats (such as SACD) won't have to reach critical mass anymore to survive. Studios can simply record everything at the highest rate, and then sell the audio at various quality (and perhaps price) levels. Since you're downloading your new album anyway, you can either buy the 96KHz 4GB version for $25, or the 44KHz 600MB version for $15, or the compressed-to-hell MP3 version for $10. It's up to you how you store and play it back. And the industry doesn't have to go through the risky business of pushing yet another audio format through. I'm not sure the labels are there yet mentally, though, since at the moment they still seem to think that the medium equals the music.

    reminds me of that story when I was growing up (in the 70's, when tube vs transitor was getting to be in vogue).

    the story goes that two engineers were arguing about the sound merits of tubes vs transistors. the tube guy liked the 'sound' of tubes and thought this was the correct sound. the transistor amp just didn't sound right to the tube guy.

    the transistor guy went back to the lab and re-evaluated his design and changed a few things. he returned to the bake-off and gave the tube guy another listen.

    "its sound great now! what did you do?" asked the tube guy.

    "well, I analyzed the distortion, hum and feedback problems your tube amp had and I installed filters and network to create the same set of intermod and distortion you find pleasing"

    morale: its not really the components, its the implementation.

    that said, I'll take an average digital signal over even a high-end analog one anyday. noise, hum and distortion are NOT my friends.

    Tom Scholz, legendary engineer/bandleader for hte rock band Boston, just last month gave an interview published at Gibson.com where he stated that he knew he was going to have to give up on analog reel-to-reel in the next year or two, because nobody would be manufacturing the tape anymore. He has switched to ProTools but hates it, and says he has to have an extra full-time professional engineer on his payroll just to operate ProTools. And he goes on and on about the specific limitations of digital recording (frequent computer crashes) and the digital medium, and the audible superiority of analog tape.

    The big problem here is that analog tape is the universal archival medium.

    100 years from now, engineers will be able to play back 2-inch 24-track tape if it's been carefully environmentally preserved. But in 2104, who will be able to access and remix the individual tracks on an IDE hard disk of an elaborately mixed album recorded in Cubase SX 2.2 optimized for a Motorola G4 processor running Mac OS X 10.2? Nobody. All we will have, if we are lucky, is a 16-bit CD with a stereo mix.

    In 1997 I interned at Crawford Productions, a huge broadcast post-production facility in Atlanta Georgia. The Martin Luther King Foundation brought in Reverend King's entire library of sermons and speeches, which were on 1/4 inch reel-to-reel and cassette, for archival restoration. While Crawford made DATs and CDs, they explained to the Martin Luther King Foundation that they were also re-copying everything to fresh 1/4 inch analog tape, and that this would be the preferred archival method and the tapes they should most jealously protect.

    What now?

    Yep. I used to work for a government agency that recorded missile telemetry on 1" 14 track analog tapes. If you stored them in a tightly controlled temperature/humidity environment they'd last a long time. The problem is that's relatively expensive, and it's not always clear what you most important reels are. We were asked to retrieve some data from a tape that was only about ten years old and it came off the reel like masking tape. We were able to restore them to a certain degree, but if it were audio it would have sounded like crap even after we were done. I had to clean the tape heads every 100' or so...

    The reality is in the dynamic domain -- you cannot afford 104 dB of dynamic range on tape. No, you can't. You can have it cheaply in digital.

    So what does everybody do? They mix so that every track is in the top 4 bits, because people perceive "louder" as "better". But it totally eliminates one of the main things that makes digital superior. The order of magnitude higher dynamic headroom. Thrown away because "we" lack the taste for anything like a quiet passage or a subdued element in a mix.

    I know of situations where 48kHz in the frequency domain is a problem, but none of them are musical in nature. 96kHz is enough of a sample rate for bat research, so it's plenty above the plateau of human proportions.

    The fidelity problem is solved. What's a problem now, is the want of specific aberrations, say as in vintage gear, that need to be simulated with signal processing, and that's by nature going to be artificial. Whether it sounds artificial is neither here nor there. A tube simulator, ribbon mike simulator, analog filter simulator, or tape saturation simulator is synthetic, and nothing synthetic is perfect.

    Good enough for production work? Certainly. Good enough that tube amps and tape decks and Telefunkens won't have a market? Wrong.

    ...I knew ye well.

    Having spent most of my teens, twenties, and thirties in recording studios (as a musician, engineer, producer, and owner), there's a lot I'm going to miss about analog recording on tape.

    • First of all, there's the act of opening a fresh reel of Ampex 456 tape -- the polymer scent, akin to the smell of a new car. You'd place the reel on the deck, thread it carefully, and then fast-forward to the end and rewind to the beginning. This would "seat" the tape so it would align with the transport. But it was almost a ritual act, the first step in recording a new project.
    • After each take, the tape would have to be rewound, either to the top of the track or to the punch point. It was an enforced pause, a chance to let your ears cool off for a few seconds or a minute, maybe take a sip of coffee or beer. I'm not the only engineer who missed this.
    • Flipping the reel: maybe once in a blue moon I'd lay a backwards guitar or piano track, or record some backwards reverb (one of my favorite effects). But when one of the channels on an old Ampex 24-track deck went south, flipping the tape and copying the track over to another track was our quick and dirty workaround (it was only a reference track anyway, and the deck was fixed the next day). Of course, nowadays we have hard drives and we all know that they never ever fail.
    • Splicing: okay, I'll readily admit that in the early '90s Digidesign Sound Designer made me hang up my razor blade and splicing block forever, but it was a hell of a useful skill at the time. I had a lot of fun in the pre-sampler days making 1/4" tape loops (some of them were 20 or 30 feet long and ran around the room, using microphone stands as tensioners).
    • The essential qualities of analog tape: head bump and tape compression. The first is really a quality of analog decks, a low-frequency emphasis between 60 and 200 Hz, where the belly of a kick drum sound lies. Tape compression allows you to selectively saturate certain tracks, like snare drum, where the effects of distortion actually work in your favor. Attempting the same thing with digital only leads to madness. Note that there's a DSP plug-in available for ProTools that simulates these qualities.
    • Longevity: properly stored and cared for, analog tape lasts decades. Perhaps even a century or more. Sure, there was that problem with 3M reels and flaking back in the '80s, but that was nothing that an hour in a convection oven at 200 degrees couldn't cure (heh). I have reels from the '70s that I can still listen to. Compare this with my own personal dead media problem: I have to keep a Mac 512K running if I want to be able to access MIDI sequences I wrote back in the mid-'80s. The software won't run on anything past System 3.2, and the file format is proprietary and not published anywhere (Opcode Sequencer 1.5). I've done straight-through conversions to a standard MIDI file format, but you lose certain features that way (named tracks, loops, etc.). Without a standard multi-track digital audio format that works across platforms and software packages, one that can be perpetuated for decades, musicians, producers, and record labels will find themselves in the same conundrum. Remember that a tape recorded on an Ampex deck will (theoretically) work on a Studer, an MCI, a Tascam, or an Otari. Think 20, 50, 100 years from now. Think reissue, remaster, box set.


    I'm not about to start the analog vs. digital flamefest. I see more good about digital than bad, but there are a few qualities of analog (particularly the last point above) that are worth preserving.

    Due to a problem with the German tape recorder, the tape was not completely erased and the voice of Adolph Hitler was intermittently heard along with Eisenhower's voice. This caused a great deal of fear and confusion among the German people

    Something similar [cox.net] happens at the end of Pink Floyd's Dark Side of the Moon. Apparently, the master tape wasn't fully erased after its last use!

    In theory. But you're not going to find any ADC's with enough dynamic range to actually do anything with digital post-processing. Think about what's going on with tape. You have non-linear smooshing of the wave form as the input reaches a critical value. This (by Fourier analysis) causes a shift upwards in frequency and (also by Fourier analysis) causes the maximum relative variation to decrease. (The maximum relative variation is the supremum of the absolute values of differences of waveform values in an interval). Now consider what a (linear) ADC is doing. It's sampling 44.1 or 96.whatever thousand times per second. Each sample consists of an input waveform measurement. You have 16 or 24 bits of accuracy to work with. That is a lot of dynamic range -- but you're still sort of screwed because if you try to do digital compression, you're going to end up with a bunch of data points in between bits. The obvious solution is to use non-linear weighting in your ADC. But this isn't going to work with ProTools or any other digital audio gear (without conversion to linear weighting, negating the benefits), and there's major inertia to deal with in the professional audio market.

    The engineer who did that was Bob Carver of Phase Linear. He characterized the highest rated tube amps and built a transistor amp with the same transfer function. In blind A/B/X tests, "high end" listeners couldn't tell the difference.

    Didn't sell.

    Then, almost as a joke, he designed the Carver Silver 7 [wardsweb.org] tube amp. 20 tubes per channel. $25,000 each. Two huge chassis per channel. Huge transformers. Same transfer function.

    Named the "best amplifier of the decade" by The Absolute Sound.

    Incorrect. The definition of irony is whatever someone reading the word irony understands it to be, no more and no less.

    If I say IANAL or 1337, are you going to complain that it's not a real word? Why would you be concerned when the 10,000th person uses irony to mean coincidence? Have you not clued in to the Slashdot dialect yet?

    Someone please mod me and the parent to which I'm replying off-topic so that others don't have to waste their time.

Stellar rays prove fibbing never pays. Embezzlement is another matter.
