Chapter 75: Formats
Here is what a person who is not an archivist learns in one very long week.
A recording is not a memory. It is a container. The container has a label, and the label lies.
The Sony wrote MP3 at 128 kilobits and named the files in a sequence, which would have been perfect.
Except that the name comes from the internal clock.
And the internal clock resets when the battery dies.
Mine had died twice. Once in a coat pocket in the winter of 2025, once in Berwyn.
So the filenames restart. There are three files called 010101_0001 on three different cards, from three different months.
The system dates on the cards were worse.
They said 2013 because that is where a reader defaults when it cannot read a real value, and they were rewritten the moment I copied them.
Marco’s sister’s neighbor’s son is called Deon. He is twenty, does helpdesk for a logistics company in Bedford Park, and would not take money.
He came over twice, ate a great deal of pizza, and saved me five weeks.
The first thing he did was tell me to stop double-clicking files.
“Every time you open one in that player it touches the file,” he said. “Read-only from here on. The originals go in a drawer and stay there.”
The four cards and the recorder went into a plastic food container. Marco wrote the date on the lid and put it in the linen closet.
The second thing he did was run something across all fourteen hundred files and produce a text file two thousand lines long.
For each recording it gave the duration, the bitrate, and the encoder timestamp buried inside the file itself.
It was also wrong, because it came from the same broken clock.
But it was consistently wrong, and consistency turned out to be the whole game.
“You’ve got seven runs,” Deon said. “Seven blocks where the clock is continuous. Inside a block the order is right. Between blocks, nothing.”
Seven blocks. Seven stretches of nights, correctly ordered within themselves, floating loose in time.
“So I have to date the blocks.”
“You have to date one file in each block,” he said. “The rest of the block hangs off it.”
Fourteen hundred files. Seven anchors. Seven facts, and the whole of 2025 falls into place behind them.
Total duration, when he added it up, was two hundred and eleven hours.
Two hundred and eleven hours of my own voice saying ounces.
I laughed at that, badly. Marco said nothing, which is his one great skill.
“How long to listen to all of it?”
Deon did the arithmetic on his phone. “At one and a half speed, no notes, a hundred and forty hours. With notes, double it.”
“I can’t do it blind,” I said. “I need to be able to jump.”
That is when he said the sentence that changed the shape of the next month.
“You don’t listen to fourteen hundred files. You look at them.”
He showed me a waveform. A gray ribbon, fat where it is loud, thin where it is quiet.
Eight hours of a sleeping baby is a flat gray line with a hum in it.
A feed is a cluster. A cry is a spike. A door is a click.
“You scan the picture,” he said. “You only listen to the shapes that don’t belong.”
“Why did nobody tell me that.”
“Because nobody knew you had two hundred hours of a house,” he said.
We built the workflow that night on the back of a Portillo’s bag.
One. Every file gets an ID. Block number, then sequence. B3-0117.
Two. Every file gets a first-pass tag from the shape alone. SLEEP, FEED, CRY, SPEECH, OTHER.
Three. OTHER gets listened to. Everything else waits.
Four. Nothing gets deleted. Ever. Not one file, not one second, for any reason.
Marco added the fifth himself, in his own handwriting, which is small and slanted and looks like a warrant.
Five. Two people know where the copies are. Always two.
I asked who the second was going to be if something happened to him.
“Moreno.”
“He’ll say no.”
“He’ll say yes, and then he’ll say something careful about it,” Marco said, “which is the same as yes.”
Deon left at eleven with the rest of the pizza. I stayed until two, tagging.
You look at a gray ribbon, type a word, press the down arrow, and look at the next gray ribbon.
By two in the morning on the tenth of November I had processed eighty-one files out of fourteen hundred and fifteen.
Every one of them was a sleeping baby and a hum.
And at B1-0079, at four minutes and eleven seconds, there was a shape I did not recognise.
A small cluster, thirty seconds long, that was not a feed and was not a cry.
I tagged it OTHER and I did not listen to it, because the rule was the rule and I had made the rule myself.
I have thought about that decision more than almost any other in my life.
