00:00:48
This week, we're talking archives.

00:00:50
Archiving your material, very important.

00:00:52
And we're joined by a couple of guests.

00:00:54
We have Ben Chesterman and Craig Field from

00:00:56
the National Australian Archives.

00:00:59
Or the National Archives of Australia.

00:01:01
I'm not quite sure.

00:01:02
Which way around is that, by the way?

00:01:04
National Archives of Australia.

00:01:08
Good.

00:01:08
Excellent.

00:01:09
We cleaned that one up.

00:01:10
Now, archiving is something we don't normally think

00:01:13
about until we've lost something.

00:01:14
But just give us a bit of a

00:01:16
background on the National Archives that you work

00:01:19
on and some of the things that you

00:01:21
actually have to work with.

00:01:22
And also, who the heck are you?

00:01:25
We'll start with that.

00:01:27
My name is Ben Chesterman.

00:01:28
I'm the Digital Audio Visual Preservation Manager, which

00:01:31
is a proper bureaucratic handful of a title.

00:01:35
So my team takes in audio, which is

00:01:39
obviously something we're all familiar with, but also

00:01:42
film sound, 35, 17.5, 16 mil film.

00:01:46
And then the video side as well, which

00:01:49
we won't talk about on this podcast.

00:01:51
It's a dirty word, I'd imagine.

00:01:53
Within my audio team is headed up, I

00:01:56
guess, by Craig Field.

00:01:58
Yeah.

00:01:58
Hi.

00:01:58
My name's Craig Field.

00:02:00
And like Ben, I'm part of this team

00:02:02
here at the National Australian Archives.

00:02:06
And yeah, I head up the audio department

00:02:08
here.

00:02:09
And we look after lots of different formats,

00:02:12
things that we can discuss later if you

00:02:14
like.

00:02:14
But yeah, it's an interesting thing.

00:02:16
Both Ben and I come from the corporate

00:02:18
world or come from music production and post

00:02:21
-production, and we're both quite new at the

00:02:24
archives.

00:02:25
So we're quite young archivists, but keen nonetheless,

00:02:31
all right?

00:02:31
So let's start with this then.

00:02:33
To give us an overview of what you

00:02:36
guys do, if someone said to you, what

00:02:39
does the audio department of the National Archives

00:02:41
of Australia do, what's your answer?

00:02:43
The remit of the National Archives is to

00:02:45
deal with all government agency records.

00:02:49
And that could be anything from the Department

00:02:51
of Defence.

00:02:52
It can be Royal Commissions.

00:02:53
It also includes the broadcasters, Film Australia, ABC,

00:02:58
SBS.

00:02:59
But unlike, say, the National Film and Sound

00:03:01
Archive, our priority is not, I guess, the

00:03:03
cultural significance of a record.

00:03:05
Any record.

00:03:06
It could be something as dry as The

00:03:08
Wool Board or the Bicentennial Authority's backstage stuff

00:03:12
at Rose Tattoo in Akkadak.

00:03:14
Or it could be some Royal Commissions and

00:03:17
really significant records like that.

00:03:19
So there is a lot of cultural tags

00:03:21
that come into it, security as well.

00:03:24
But obviously the primary remit is to make

00:03:27
that material safe and accessible to the researchers,

00:03:31
the public, and those agencies in the future.

00:03:34
I guess the U.S. equivalent is the

00:03:36
Library of Congress?

00:03:37
Yeah, absolutely.

00:03:38
That's correct.

00:03:39
And we very much engage with them in

00:03:41
regards to what our specs are and TCO6

00:03:44
and all these sorts of specifications.

00:03:46
And that stuff is done with the Library

00:03:48
of Congress and also, I will add, within

00:03:50
the agencies here.

00:03:51
So NFSA and us work quite closely together.

00:03:54
So the Film and Sound Archive, to be

00:03:56
clear though, is separate to you guys, obviously,

00:03:59
but does a similar thing.

00:04:00
But it's sort of the archive of Australian

00:04:02
treasures, I guess, isn't it, in terms of

00:04:04
recordings?

00:04:05
Yeah, that's right.

00:04:05
There's definitely a sort of lens of cultural

00:04:08
significance that they put onto whether they accept

00:04:11
a transfer.

00:04:12
With us, we probably accept everything.

00:04:15
And then there's a lot of crossover.

00:04:16
They'll contact us because they may only have

00:04:18
a low-res copy or a dub of

00:04:21
something.

00:04:22
We may have the original source.

00:04:24
So we do a lot of that.

00:04:25
Oh, wow.

00:04:25
So you're sort of backing each other up

00:04:27
as well, almost, then archiving each other.

00:04:29
Absolutely.

00:04:30
Yeah, absolutely.

00:04:31
Yeah, absolutely.

00:04:31
And the ABC too.

00:04:32
We do almost daily transfers back and forth

00:04:37
between ABC Radio, Archives and us when they

00:04:40
have things that we need and vice versa.

00:04:42
The ABC is the Australian Broadcast Commission, guys,

00:04:45
for you guys in America.

00:04:46
That's what the ABC is.

00:04:48
So let's go through the process then.

00:04:51
If something comes in to you guys, how

00:04:54
do you sleep soundly at night knowing that

00:04:56
it's securely archived then?

00:04:58
What's the process?

00:04:59
What happens?

00:05:00
So I guess on the physical side, you'd

00:05:02
start with a transfers team.

00:05:04
So they would engage with the agency to

00:05:07
make sure that's packed properly and all the

00:05:10
rest of it.

00:05:10
Obviously the first part of it is getting

00:05:12
the material to our repository safely.

00:05:14
Then everything is stored in the proper conditions

00:05:17
depending on that format.

00:05:19
And there are vaults here in Sydney as

00:05:21
well as in Canberra, probably the largest one

00:05:23
in Canberra.

00:05:24
And depending on those formats, so film sound

00:05:27
needs to be dealt with much colder temperatures

00:05:30
generally than, say, an optical format like CDEC.

00:05:33
So that's part of it.

00:05:35
And then also there's an accessioning they call

00:05:38
within the archives.

00:05:39
That's where a team will sit down with

00:05:41
the paperwork or the files that come from

00:05:43
the agency and record that in our database

00:05:47
so that we actually describe that record, as

00:05:50
it's called, and make sure that that's accurate.

00:05:53
Then in terms of what we do digitising,

00:05:56
I'll hand over to Craig for that side

00:05:58
of things and treatment and so on.

00:05:59
Well, again, I guess the first thing we

00:06:01
do is have a look at the format

00:06:02
and see what there is.

00:06:04
There's a wealth of knowledge here at the

00:06:06
archive, as you can imagine.

00:06:07
There's a lot of people like Ben and

00:06:09
myself who've had pretty extensive professional careers and

00:06:13
find themselves at the archives.

00:06:15
In my second week here, someone who's been

00:06:19
here a long time put his hand on

00:06:21
my shoulder and said, don't worry, son, everything

00:06:24
old ends up at the archive.

00:06:29
Thank you so much.

00:06:31
There's a lot of grey hair in the

00:06:32
room right now.

00:06:35
I haven't been offered a job yet, but

00:06:38
maybe my time is now.

00:06:40
Your time may be coming.

00:06:44
So that's one of the first things that

00:06:47
we do, obviously, as Ben mentioned.

00:06:49
It goes to lending.

00:06:50
It's very well cared for and put in

00:06:53
different spaces.

00:06:54
At our repository, for example, we've got cold

00:06:56
rooms that are, you know, supersonic temperatures that

00:07:00
are climate controlled, so to speak, where the

00:07:03
air is refreshed every X amount of time.

00:07:07
When there's certain amounts of particles in the

00:07:09
air, the air is extracted and then put

00:07:10
back in so that canisters can be kept

00:07:14
at the best condition.

00:07:15
We've got dehumidifying ovens and things like that

00:07:20
for analog tape.

00:07:22
Obviously, it's just best practice, really, and all

00:07:25
those different formats require different techniques and different

00:07:30
things, you know, right down to a HB

00:07:33
pencil and a cassette tape.

00:07:36
So some of it's preserving the actual original

00:07:39
format and the earliest, most original format possible

00:07:42
physically for as long as possible, and then

00:07:45
part of it is transferring this to a

00:07:48
medium that can be replayed over and over.

00:07:52
Yeah, absolutely.

00:07:53
Some things can't be shared from our particular

00:07:57
archive, the National Archives.

00:07:59
Some things are kept for under government policy

00:08:03
and some things are available for public research

00:08:05
and public access.

00:08:08
But ultimately, what we try to do is,

00:08:12
and again, I'm quite new at the archive,

00:08:15
but it is a complete surrogate copy of

00:08:19
the content, as pristine as humanly possible, and

00:08:22
that obviously, say, in the, if we're talking

00:08:28
a quarter-inch tape that's 40 years old,

00:08:30
that can require a fair bit of care

00:08:34
and understanding about what the format is and

00:08:38
preparation before you do the recording because you

00:08:41
might only have one shot of it.

00:08:43
That's right, one shot.

00:08:45
It's a one-take thing.

00:08:46
Yeah, one shot.

00:08:47
Which is, you know, when we were talking

00:08:49
earlier about DSD and things like that and

00:08:51
no editing, that really motivated me professionally as

00:08:57
an engineer that you've got one shot at

00:08:59
this, man.

00:09:00
You've got to get everything set up, get

00:09:01
it right, get it done.

00:09:04
Why is that?

00:09:04
Because a lot of people listening may not

00:09:06
understand that the process of, we call it

00:09:09
baking the tapes here in the US, but

00:09:10
why is it you get one shot at

00:09:13
that?

00:09:14
Is it because after the tape is baked

00:09:16
and then it is played, it falls apart,

00:09:18
something like that?

00:09:19
Not necessarily.

00:09:20
In fact, if you don't bake it, it'll

00:09:22
fall apart more possibly, I think.

00:09:25
Yeah, that is right.

00:09:26
The baking is to try and minimize the

00:09:29
shedding, but you will get some.

00:09:31
But the baking does affect the emulsion, so

00:09:33
you are wanting to try and digitize well

00:09:39
on your first pass.

00:09:40
You have to know, I guess.

00:09:42
Right.

00:09:42
Do you know what we found that works

00:09:43
great for baking?

00:09:44
Do you remember?

00:09:46
I mean, they're even perfectly sized like the

00:09:47
reals.

00:09:48
So do you remember back in the day

00:09:49
they used to have these, like, get all

00:09:50
your bananas and slice them and slice your

00:09:52
strawberries and then you dehydrate them?

00:09:54
Food dehydrators.

00:09:55
Yeah, and really you're dehydrating the tape, and

00:09:57
that works better than tossing it in the

00:09:59
oven at 150 degrees, I think.

00:10:01
But what do you guys do as far

00:10:03
as baking tape?

00:10:04
We've got a microwave downstairs that is thrown

00:10:05
in every five seconds.

00:10:07
That's right.

00:10:07
It's in the kitchen.

00:10:09
I don't know about rust in a microwave.

00:10:12
Yeah, yeah.

00:10:13
Look, technically, don't use the term baking, okay,

00:10:18
because the last thing you want to do

00:10:22
is have a baked tape.

00:10:23
Well, hang on.

00:10:24
When you're recording to tape, we call it

00:10:26
baked.

00:10:26
It's baked in once you've recorded it to

00:10:28
tape.

00:10:29
You certainly can have it.

00:10:31
Yeah, yeah, it is.

00:10:32
And most of the people in the studio

00:10:33
are baked.

00:10:34
That's not a problem.

00:10:35
I don't know about that.

00:10:36
That's a given.

00:10:38
But when you're getting there, you don't want

00:10:41
to bake that tape, okay?

00:10:42
You do want to dehumidify it.

00:10:45
Dehydralize is the term they use.

00:10:48
Dehydralize.

00:10:49
And as Ben stated, what they've found, and

00:10:52
it was the Library of Congress that came

00:10:55
up with some of the disciplines that they

00:10:57
use in these ovens, they used to use

00:11:01
a process where the ovens were set to

00:11:03
38 degrees and they would put a tape,

00:11:07
two-inch, quarter-inch, one-inch, they would

00:11:10
put in there for four days.

00:11:12
And they used that standard for many, many

00:11:15
years, and it's only recently after extensive tests

00:11:19
that they've now changed that temperature to a

00:11:22
standard of about 48 degrees and a constant,

00:11:24
and they give it 48 hours in there.

00:11:28
And they have found that that helps the

00:11:31
emulsion, you know, pretty much just rejoin the

00:11:35
tape so that it's solid, so that you

00:11:37
can play it back.

00:11:38
Because after a period of time, there was

00:11:41
a lubricant that was commercially applied within the

00:11:46
manufacturer of the tape, and that lubricant amongst

00:11:50
other chemicals slowly starts to break up and

00:11:53
causes the emulsion that's on the top of

00:11:57
the tape that we would magnetize to lift

00:12:00
and shed and break up.

00:12:03
And the warmth and the constant warmth and

00:12:06
that constant temperature helps that emulsion just join

00:12:10
back to the back of the tape and

00:12:12
can give you a chance of...

00:12:15
So it's still only one pass, though, by

00:12:17
the sounds of it.

00:12:18
It's not necessarily one pass.

00:12:21
I mean, after you bake it, it's been

00:12:22
through trauma, but it's not necessarily completely dead.

00:12:25
But every playback, I mean, technically every playback

00:12:28
of a tape is wearing off, you know,

00:12:31
it's friction.

00:12:31
Yeah, that's right.

00:12:32
It's like a record.

00:12:33
No, you're right, Robert.

00:12:34
It's not always one pass, but generally the

00:12:37
archival way is to try and get a

00:12:39
single pass in, so you're not doing edits

00:12:41
and anything like that.

00:12:43
But I would add to that, the ovens

00:12:45
that are used by us and vendors, I

00:12:47
should add, there's digitization vendors that do work

00:12:50
for all the archives, basically scientific medical ovens

00:12:54
because they're required to be at those really

00:12:56
low, essentially, low but stable temperatures.

00:13:00
And I have worked on a project, I

00:13:02
won't name names, but someone had an oven

00:13:04
that completely malfunctioned.

00:13:06
The thermostat went up in the middle of

00:13:08
the night and came in the morning.

00:13:10
They had some lovely sculptures, but not great.

00:13:13
We took a melted quarter-inch reels.

00:13:15
It was quite a sight.

00:13:17
That's when it's baking.

00:13:19
That's when it's baking.

00:13:19
It's literally baking.

00:13:21
That's right.

00:13:22
And I would add as well that a

00:13:23
big part of what Craig and the team

00:13:25
do here is to evaluate the issues with

00:13:27
that source before they even start.

00:13:29
You might have other issues that aren't related

00:13:32
to hydrolysis or sticky shed syndrome as it's

00:13:35
often called.

00:13:35
There's another one which is known as loss

00:13:38
of lubricant where the actual lubricant on the

00:13:40
tape is worn off and then you get

00:13:44
this quite noticeable squeaking as it goes across

00:13:46
the reels and the capstans.

00:13:48
And that's a different issue.

00:13:50
You'll actually deal with that in a different

00:13:52
way by using solutions drip-fed onto the

00:13:56
tape as it's heading over the heads.

00:13:59
You can use other…

00:14:00
What's the stuff the NFSA were starting to

00:14:03
play with?

00:14:04
Hydromethazone.

00:14:05
Yeah, hydromethazone is a new product.

00:14:07
I'd like to try some of that.

00:14:11
That's almost like a silicon-like solution.

00:14:14
It's used to help with that loss of

00:14:16
lubricant.

00:14:16
They found that on old cassettes as well

00:14:19
that that's worked really well.

00:14:20
Well, I was just going to ask, you

00:14:21
mentioned it before, has anybody come up with

00:14:23
anything better than the HB pencil on a

00:14:25
cassette yet?

00:14:26
I mean, really?

00:14:27
Look, there were originally in the 80s, funnily

00:14:30
enough, there were winders.

00:14:32
They were commercially available.

00:14:34
Yes, they were.

00:14:34
I remember.

00:14:34
And they're very hard to get because after

00:14:36
you've…

00:14:37
We're looking down the barrel of one particular

00:14:39
project soon that's got about 500 cassettes and

00:14:42
they all need analysis, they all need checking,

00:14:45
they all need revision, tightening, and ultimately, as

00:14:51
Ben sort of insinuated, when we're archiving something,

00:14:55
it needs to happen in one pass without

00:14:58
any editing.

00:15:01
So it needs to be one complete recording

00:15:04
or it stops being a legal document, it

00:15:06
stops being a surrogate copy.

00:15:09
So if you put a cut in there

00:15:11
or you put an edit or you have

00:15:13
to stop for some reason, and this includes

00:15:15
if we're doing top secret things, if someone

00:15:17
enters the room, that recording is no longer

00:15:20
a legal document.

00:15:22
Wow.

00:15:22
And you would find that with archiving throughout

00:15:24
the world so that when you're doing certain

00:15:26
things, it's just like engineering, it's the preparation

00:15:30
and the means and the communication prior to

00:15:35
it and then the actual function of the

00:15:38
recording.

00:15:39
So there's a few elements involved.

00:15:43
No, the HP pencil is still pretty important,

00:15:46
I think.

00:15:47
And if anyone knows where there's a whole

00:15:49
stash of winders, old stock from the 80s,

00:15:53
please write to Craig at the archive.

00:15:56
Craig, I think I do actually have one.

00:15:58
I have a cassette repair kit.

00:16:00
Name your price.

00:16:01
Well, it's my birthday in July, so you

00:16:04
can let me know.

00:16:06
Send us a box.

00:16:07
You've just beggared one more question for me.

00:16:09
Given the high stakes that's going on, what

00:16:11
has more pressure involved, recording an orchestra or

00:16:14
a three-meter piano or sitting down to

00:16:16
dub a cassette?

00:16:17
Oh, look, you face all of the problems

00:16:20
just like we did our technical problems this

00:16:22
morning, just hooking up all these sorts of

00:16:25
lines.

00:16:25
You just face them as they come as

00:16:27
an engineer.

00:16:28
And I think you get so used to

00:16:30
things not working and figuring out problems that

00:16:35
you either embrace that in your career and

00:16:38
realize that that's one of the largest parts

00:16:41
of the career is you plug something in.

00:16:43
I came this morning, plugged something in, and

00:16:46
one of my leads isn't working.

00:16:48
Now, it's like, come on, one of the

00:16:50
leads.

00:16:51
I just couldn't believe it.

00:16:53
And so it worked yesterday.

00:16:55
Yeah, of course it did.

00:16:56
I mean, that's the old set up the

00:17:01
session the night before and you leave it

00:17:02
open.

00:17:03
You don't close Pro Tools.

00:17:04
You don't do anything.

00:17:04
You come in the next morning and two

00:17:06
mics aren't running or something's not working.

00:17:08
What the hell is going on here?

00:17:10
Exactly.

00:17:11
Yeah, that's it, right?

00:17:12
That is the law of it.

00:17:14
So I would say to answer your question,

00:17:18
when, say, you're recording a small ensemble, no

00:17:21
one really knows.

00:17:23
When you're the engineer and the technician, even

00:17:25
if there's a producer with you, maybe the

00:17:27
producer understands, but few people really know what's

00:17:30
going on, especially with trying to capture the

00:17:33
dynamic and the room and capturing the air

00:17:35
and the performance and all of those sorts

00:17:37
of things that you're trying to oversee.

00:17:39
Mostly the musicians are very focused on themselves

00:17:41
and their performance.

00:17:43
I've found, coming from that and working at

00:17:46
the archives, that you're surrounded by a whole

00:17:49
group of really professional people who are totally

00:17:52
kind of with you.

00:17:54
So there's a great deal of support.

00:17:56
There's a great deal of knowledge, and we

00:17:58
can go down to Canberra or call up

00:18:00
someone who's got 20 years' experience with a

00:18:03
particular format, and they'll talk you through it

00:18:06
over the phone, hold your hand, and if

00:18:09
it does go wrong, they'll probably buy you

00:18:11
a coffee at the end of it.

00:18:13
It's a different world, but it's a very

00:18:16
supported environment to work in, and it's great

00:18:19
being there's just so much knowledge here.

00:18:22
It's fantastic.

00:18:24
What's one of the most difficult formats that

00:18:26
when you're presented with it, you're thinking, oh

00:18:28
boy, what's one of the challenging ones?

00:18:32
In audio land?

00:18:33
DAT tapes.

00:18:33
DAT tapes that decide to crap out.

00:18:36
DAT tapes.

00:18:36
DAT tapes that fuck up.

00:18:39
Anything with a spinning head, right?

00:18:40
A spinning head tape.

00:18:42
We were all of an age that we

00:18:43
used DATs back in the day, and they

00:18:45
were bad even then.

00:18:46
If you were recording a TASCAM, you couldn't

00:18:48
play back in a Sony, all that nonsense.

00:18:50
So that continues.

00:18:52
We have to have a range of machines,

00:18:54
and we have a bunch of different brands.

00:18:56
Yeah, DAT tapes.

00:18:57
I used to carry around a little portable

00:18:59
to do some production sound mixing for a

00:19:01
film, real low budget.

00:19:03
And you would just pray that that thing

00:19:05
wasn't going to drop bits and drop out.

00:19:08
So here's a question.

00:19:10
First of all, actually one quick question.

00:19:12
Have you ever had to bake a DAT

00:19:13
tape?

00:19:14
Well, yes.

00:19:14
You should bake DAT tapes.

00:19:16
And then the second question, which is something

00:19:19
I've noticed, and I'm wondering if you've noticed

00:19:20
yourself.

00:19:21
I've done a few projects where someone brings

00:19:24
me all their old tapes, and you dry

00:19:25
them out, and then you get your one

00:19:27
playback.

00:19:28
And I have seen it.

00:19:29
If you guys haven't seen this, it goes

00:19:31
through the pinch roller, and it plays back.

00:19:33
And coming off that pinch roller, one piece

00:19:36
of tape becomes two.

00:19:37
And the second piece of tape just disintegrates

00:19:40
because it's just literally the oxide.

00:19:43
And the funny thing I've noticed is that

00:19:44
sometimes when people bring these projects, the cheap

00:19:47
tape from Radio Shack doesn't mess up.

00:19:51
And the expensive Ampex or BASF tape, that

00:19:57
stuff delaminates.

00:19:58
And you really have to make sure you

00:20:00
bake that stuff.

00:20:01
But the old crappy tapes, whatever they did

00:20:04
differently on them, those seem to deal with

00:20:06
the age better.

00:20:07
I think it's the additional cheap uranium content

00:20:10
in the Radio Shack.

00:20:12
It just seems to go forever, you know?

00:20:15
You don't rub it.

00:20:16
You're putting the radiation in Radio Shack.

00:20:18
Is that what we're saying?

00:20:19
Yeah.

00:20:19
I really think you're right, Robert.

00:20:22
It's funny.

00:20:23
I came here and was surprised to learn

00:20:26
that Ampex 456, which when I started out

00:20:29
was like, that's the tape.

00:20:31
That's what you use.

00:20:32
It does not age well at all.

00:20:35
There are other brands that weren't as well

00:20:37
considered back in the day that just, for

00:20:39
whatever reason, they just hold their condition better.

00:20:42
And so they'll require treatment.

00:20:45
I was thinking another format that's a nightmare

00:20:48
are optical CD-Rs, you know, the ones

00:20:51
you record.

00:20:51
I was going to say DVDs.

00:20:52
Don't they have a shelf life and they

00:20:54
just start to eventually start throwing errors?

00:20:58
In regards to your guys' audience, a lot

00:21:01
of us would have those DVD-R backups,

00:21:04
CD-R backups of our sessions.

00:21:05
Those are my archives, by the way, for

00:21:07
a lot of my media.

00:21:08
That's it.

00:21:09
Disc rod is very real.

00:21:11
I think we're all probably familiar with it.

00:21:14
You pull out a disc and it's got

00:21:15
those big holes in it.

00:21:16
It's where the reflective layer just breaks down,

00:21:20
and that can be anything from light-related

00:21:22
chemical breakdown.

00:21:24
So, yeah, they're one we'd really want to

00:21:26
be getting off.

00:21:27
Just on that, a really cool approach, and

00:21:30
we were talking about the HP pencils before,

00:21:33
but what we've really liked coming into this

00:21:35
is some of the novel approaches that are

00:21:37
really starting to come out now.

00:21:38
People are using 3D printing to build new

00:21:43
machines, essentially new components for these old machines.

00:21:46
At the same time that Craig and I

00:21:48
have come in here and we're digging back

00:21:49
into old machines that we haven't used in

00:21:52
40 years, there's that element of finding obsolete

00:21:56
equipment, as it's called, and cleaners, the old

00:21:59
bow cleaners that you string up a tape

00:22:01
and run it through first.

00:22:02
There's also some really novel stuff being done

00:22:05
with 3D printing, using new machines to be

00:22:07
able to take a tape out of its

00:22:10
case, roll it around, have a look at

00:22:13
it, really kind of judge it.

00:22:15
And with DATs, I've seen people using the

00:22:18
old data DATs that we would use to

00:22:21
put data to in the old day, and

00:22:23
they're actually extracting the audio data from that

00:22:26
DAT using an old SCSI setup, and so

00:22:30
they're not actually having to run for an

00:22:32
old Sony or a Tascam machine.

00:22:33
So like Craig said, around the world there

00:22:35
are archivists, they're very sharing, there's no sort

00:22:38
of competition.

00:22:39
It's a special DAT drive that reads data

00:22:44
and audio.

00:22:45
Yeah, that's right.

00:22:46
Because Mark Gilbert used to use those, I

00:22:48
think they were the Connor drives, and he

00:22:50
had DAT Studio, and you could load DAT

00:22:53
tapes in at double speed via data instead

00:22:56
of via as audio playback.

00:22:59
Yeah, that's right.

00:22:59
But you had to find those special DDS,

00:23:01
what was the DAT format, DDS3 was that?

00:23:06
DDR3?

00:23:07
DDR3 was it?

00:23:08
Yeah.

00:23:08
Yeah, and then you also have to find

00:23:10
an old SCSI card and something that can

00:23:12
run that.

00:23:13
And an old computer that can run the

00:23:16
software.

00:23:17
I like to ask the audience questions that

00:23:20
somebody would love to ask.

00:23:23
So what's the oldest piece of audio medium

00:23:26
that you had to archive?

00:23:30
A wax cylinder.

00:23:31
We're both pretty new, but down in Canberra,

00:23:34
we've both been down there.

00:23:35
They have some wire recordings, they've got quite

00:23:38
a substantial.

00:23:40
And I can't remember the technician's name down

00:23:44
there.

00:23:44
Aren't wire recorders after wax cylinders though?

00:23:47
I think wax cylinders predate wire recorders.

00:23:48
Yeah, they've got wax as well.

00:23:50
They've got wax as well, but because of

00:23:52
Australia being such a broad country and those

00:23:56
wire cylinders were easy to transport, there was

00:23:59
quite an industry here in Australia at that

00:24:01
time.

00:24:01
So people were sending them out to sheep

00:24:03
stations and different places like that.

00:24:05
They were quite robust.

00:24:07
And when you see what happens if you

00:24:10
take the spool, there's two kilometres of very

00:24:15
fine wire on that thing.

00:24:17
And when it comes off badly, it looks

00:24:20
like steel wool.

00:24:24
Like an afro.

00:24:24
It's a mess.

00:24:26
It's terrible.

00:24:27
And listening to their stories of having to

00:24:31
detangle those and put them back, but they've

00:24:33
got quite an advanced understanding of that.

00:24:36
And their technician down in Canberra has actually

00:24:38
gone over to university in America and lectured

00:24:40
on it.

00:24:41
And they've developed, just so they could get

00:24:44
an understanding of the magnetism techniques, they've used

00:24:47
a horn and done their own wire recordings.

00:24:51
So they've actually recorded through old machines just

00:24:55
so they could get a better understanding of

00:24:57
how it was originally done, so they could

00:24:59
also do the transfers because there was so

00:25:02
much significant content.

00:25:04
Now I would say with some of the

00:25:05
formats, what's interesting is some of the older

00:25:08
formats, including wire recording, some of the early

00:25:13
shellac and vinyl, they're really at very low

00:25:17
risk because they're still functioning quite well.

00:25:20
And they come off and they work and

00:25:22
sound great.

00:25:23
And I would say the same for tape

00:25:25
and quarter-inch, if it's been stored well.

00:25:27
And there were very good technicians back in

00:25:31
the day when people were recording.

00:25:32
The stuff that we get obviously comes from

00:25:35
the National Broadcaster and things, so it's really

00:25:37
well recorded.

00:25:38
The sound that comes off them is fantastic,

00:25:42
even on a 40-year-old Studer.

00:25:44
And at least compared to film, it doesn't

00:25:46
catch on fire if you store it wrong.

00:25:47
Yeah, yeah, that's right.

00:25:49
I guess film sound's probably a little out

00:25:52
of the scope of this podcast, but some

00:25:54
of the guys, I think you've probably heard

00:25:56
of vinegar syndrome, where the acetate breaks down

00:25:59
and you get a very strong smell of

00:26:01
vinegar.

00:26:03
And Tony Ravichow, head film sound guy, calls

00:26:07
them hockey pucks when they get so bad

00:26:09
that you pull out these reels of mag

00:26:12
and it's just a solid lump.

00:26:14
Just solid, yeah.

00:26:15
He will sit there.

00:26:16
An old drummer, he's a drummer, so he

00:26:18
has an old drum mic stand set up.

00:26:21
It's almost like a hairdryer.

00:26:23
Yeah, it's like a little hairdryer.

00:26:25
And then blows that onto the reel and

00:26:28
bit by bit just pulls it out.

00:26:30
Pulls it apart.

00:26:31
Wow.

00:26:31
And then he can actually get a transfer.

00:26:33
Porno mag syndrome.

00:26:34
And we use these big old...

00:26:39
You must really, really want to see what's

00:26:42
on or hear what's on that.

00:26:43
Yeah, totally.

00:26:44
Well, it's our job.

00:26:45
It's not about something we really need to

00:26:48
hear it.

00:26:49
It's our job.

00:26:51
So we get given these things and some

00:26:53
things have been stored really quite poorly or

00:26:55
they've been moved around or government departments have

00:26:57
closed down.

00:26:59
They've been put in boxes and stored and

00:27:02
left to the elements and they come to

00:27:04
us and it's not so much, oh, we

00:27:06
really want to hear it.

00:27:06
We have to hear it.

00:27:08
It's our job to get it off.

00:27:09
We need it stashed away.

00:27:10
We need to find what it is and

00:27:11
then we need to record it.

00:27:13
And it's really exciting.

00:27:15
That's a really...

00:27:17
We get given the resources.

00:27:20
We get given the support and the time

00:27:22
to do it.

00:27:23
It's like archaeology.

00:27:24
Yeah.

00:27:25
I'm sure there's a bunch of top secret

00:27:26
stuff along the way that you can't talk

00:27:28
about, but is there anything that's come through

00:27:29
that you've gone, wow, they recorded that?

00:27:32
That's really great.

00:27:33
I recently got to listen to a fantastic

00:27:37
Nick Cave recording that he did when he

00:27:41
was quite young and he was still living

00:27:43
in Berlin, but he'd come back to Australia

00:27:45
and he was sitting into...

00:27:47
It was a program for the ABC that

00:27:49
ran for a very long time and he

00:27:50
read from a book and also sat and

00:27:53
played at the piano and sung.

00:27:54
It was beautifully recorded.

00:27:56
The tape looked pretty damaged and we did

00:27:59
some work to it and we cleaned it

00:28:02
and we ran it through our cleaners and

00:28:03
we rehydrated it and then we did a

00:28:05
take.

00:28:05
And just hearing a great recording, a young

00:28:09
prolific artist coming from this beautifully recorded and

00:28:14
engineered process and just hearing it from tape,

00:28:17
it just sounded fantastic.

00:28:19
Do you ever improve the recordings?

00:28:21
Like if the original deck had Wow and

00:28:23
Flutter on the input, do you ever try

00:28:26
to go in and take out the Wow

00:28:28
and Flutter from what would have been a

00:28:30
flawed recording?

00:28:31
Not the Preservation Master, no.

00:28:33
So I guess probably should go to that.

00:28:35
We create a Preservation Master, which is just

00:28:38
the transfer that I mentioned, the straight in.

00:28:40
And then if a researcher or a member

00:28:43
of the public wanted to access that and

00:28:45
that was approved, we might then do some

00:28:48
treatment, some editing even.

00:28:50
Some restoration to it.

00:28:52
To make it more...

00:28:53
But generally as a rule, restoration is not

00:28:55
part of what we're doing here.

00:28:58
Where the brick lays.

00:28:59
Way back before wax cylinders, I forget who

00:29:01
it was, he came up with a system

00:29:03
called audiograms and he was able to take

00:29:07
a sketch of the waveform, but there was

00:29:11
nothing to play it back.

00:29:14
And then I think around 2000, early 2000s,

00:29:16
I began taking these photographs or these audiograms,

00:29:20
however he captured them, they would load into

00:29:22
the computer and convert it back to a

00:29:24
waveform.

00:29:24
And it was literally captured in 18 whatever,

00:29:27
60, and never played back until 2005.

00:29:32
That's quite special, isn't it?

00:29:33
That's amazing.

00:29:34
Well, some of the broken...

00:29:37
They now have a laser technology where they

00:29:40
can look at broken shellac and they can

00:29:42
grab the pieces.
