Track Twelve, River Ambience

I label everything. It’s the one habit that survived the divorce, the move to Narvarte and fifteen years of directors who say “just get me some atmos” as if atmos were something you could buy at the OXXO with a Gansito. File name, place, date, take, microphone, notes. When you have nine thousand hours of wind and markets and empty hospital corridors on four hard drives, the label is the only road back to anything.

So this is how it went, in the order the files went.

RIOATOYAC_ZIM_D1_T01.wav. 14 Feb. 06:12. MS pair, 3 m from bank, shallows over stones. 11 min 40 s. Notes: good. Rooster across the water at 04:10, usable. Truck on the highway at 07:55, cut.

Bruno wanted a river that sounded like it had been crying. His words. He was finishing a film about a family in the Valles Centrales who lose a boy to the water, and he had shot the whole thing with the river practically muted, because his production sound man recorded it with a lavalier in a sandwich bag (I am not making this up). Six weeks of pickups in a studio in Coyoacán and the one thing still missing was the river itself.

“Not pretty,” he told me on the phone. “Not a spa. A river you wouldn’t let your kid near.”

I said I could do that. I have a seven-year-old. I know exactly what a river you wouldn’t let your kid near sounds like. It sounds like nothing, mostly. A low hiss. And something heavier rolling underneath it that you only notice once you’re standing in it.

I left Mateo with my mother on the Thursday, drove the nine hours to Oaxaca with one stop for tlacoyos outside Puebla, and by six the next morning I was standing in the Atoyac below Zimatlán in borrowed waders, a stretch where the water still moves properly, with a mezquite on the far bank and a dog that followed me for two hours and then lost interest.

The first day was good. I want that on record. I listened to every take on the way back to the hotel in the city, headphones on, laptop open on the passenger seat, which you are not supposed to do while driving and which I do every time. Water over stone. A kingfisher. The rooster. Nothing else.

RIOATOYAC_ZIM_D2_T04.wav. 15 Feb. 17:30. Hydrophone under the bank + MS pair. 22 min. Notes: low rumble off the bridge pylons, gorgeous. Something at 09:14. Check.

The something at 09:14 was a woman crying.

Not loud. In a car you would have heard river. She sat underneath the water, maybe twenty decibels down, in the band where a human voice lives, three hundred to a thousand hertz, and it was the long, pulled kind of crying that doesn’t stop to breathe. I thought: a woman on the far bank. I hadn’t seen anyone, but rivers carry voices in strange ways, and there were houses up past the mezquite.

That night in the hotel, with the whole room smelling of the chocolate mill downstairs, I opened the take in the restoration software and painted her out. You can do that now. You draw around a sound on the spectrogram like you’re circling a stain, and the program lifts it and fills the hole with its best guess of what was behind it. It took forty minutes. The river closed over the gap as if nothing had been there.

I also checked the other channel. This is the important part. The hydrophone, the one sitting under the water, wrapped in a sock against the current.

She was on that too. Same timecode. Same level.

You do not hear a woman on the far bank through a hydrophone.

* * *

RIOATOYAC_ZIM_D3_T07.wav. 16 Feb. 05:50. MS pair, 1.5 m from bank. 14 min. Notes: crying again, 00:40 to end. Closer?

I should explain “closer”, for people who don’t do this. Every sound reaches you twice. Once straight from the source, and then again a few milliseconds later, softer, off every rock and wall and tree around it. The ratio between those two is how your brain measures distance without asking you. A voice across a river is mostly echo. A voice next to you is mostly voice.

On day two she was mostly echo. On day three, by my ears and by the meters, she was halfway across the water.

I cleaned her out of that one too. It took longer, because she wasn’t staying in one band now. She climbed and dropped, the way a voice does when a person is saying something, not just crying.

I called Bruno and told him the location was compromised. Somebody upstream. I’d move.

“Compromised,” he said. “Is it a lady?”

“Why would you say that?”

“Because the people there told us. When we shot. Don’t take the boy down to the water after dark, there’s a lady.” He laughed. “We paid a señor two thousand pesos to sit on the bank with a flashlight every night.”

“And did he see anything?”

“He fell asleep, Lucía. Every river in this country has a lady. Move if you want. I like the Atoyac.”

I moved a kilometre upstream, where the river squeezes between two walls of grey rock and gets loud. Loud water is good if you are hiding from something. I had never had that thought before in my life, and I had it standing in a river with a forty-thousand-peso microphone in my hands.

RIOATOYAC_ROCAS_D4_T01 to T09.wav. 17 Feb. Various. Notes: all takes, all of them. Stop labelling her as noise. Label her.

* * *

I’m going to tell the next part plainly, because I’ve told it to two doctors and a priest and the plain version is the only one that holds still.

On the fourth night I played her backwards.

It’s an old trick. When you can’t tell what a sound is, you flip it, and your brain stops guessing and just hears. And there was something about the way she climbed and dropped that bothered me. Her phrases swelled at the ends and cut off clean at the start. That is what speech sounds like reversed. Breath sucked in instead of let out.

So I took the cleanest stretch, T06, three minutes, and reversed it, and turned it up, and closed my eyes.

Names.

Said slowly, with a space after each one, the way you call children in from the street for dinner. Tomás. Lupe. Efrén. Juan Carlos. Marisol. Chuy. Then the space, longer, as if she was waiting for one of them to shout back. Then more. I counted fifty-one in three minutes and stopped counting. Some of them were old names, names nobody gives babies any more. Eusebia. Crescencio. Some were new. A Kevin. A Brayan with a y, I could hear the y somehow.

The last one on T06 was Mateo.

I sat on the hotel bed and told myself Mateo is the fourth most common boy’s name in Mexico. I looked it up to be sure. I was right, it was fourth. Then I reversed T07, and T08, and T09, and on T09, at the very end, after the longest space of all, she said Mati.

Nobody calls him Mati. Not my mother, not his father, not his teacher. Mati is mine. It’s what I called him when he was a fat baby who wouldn’t sleep unless I walked him up and down the hallway, and it’s what I still call him when nobody else is listening.

I phoned home. It was ten at night. My mother said he was in the bath, she’d let him stay up because he’d been good.

“Put him on.”

There was the sound of the phone being carried, the echo of tiles, water running out of a tub.

“Mamá. The lady was singing again.”

I asked him what lady, very calmly. I’m proud of how calmly.

“The one in the drain. She sings when the water goes down. She’s sad.”

“What does she sing?”

“Names,” he said, as if that were obvious, as if everybody’s drain sang names. “She asked me my name and I said Mateo and she said no, the other one.”

“Did you tell her the other one?”

“She already knew it,” he said. “She said it like you.”

* * *

I drove back to the city that night. Nine hours. I didn’t play anything in the car, not the radio, not my files. I kept the windows up so I wouldn’t hear the wind. At a toll booth near Esperanza the girl in the booth said something to me and I didn’t catch it and I nearly screamed at her to stop talking.

Mateo was asleep when I got in, sideways across my bed with his feet on my pillow. I sat in the bathroom with the light off and looked at the drain in the tub. My mother found me there at six in the morning.

“Ay, mija,” she said. “There’s nothing in there. Every drain in this city is a river that forgot.”

She meant it as a joke. She grew up in Oaxaca and has never trusted Mexico City water, the way it comes from nowhere you can see. But she was right in a way she didn’t mean. Our building is three blocks from the Viaducto, and the Viaducto is a river. The Río de la Piedad. They put it in a pipe in the fifties and built eight lanes of traffic on top of it. Every drain in Narvarte runs down to it in the end. I had known that for years as a piece of trivia. I knew it differently that morning.

At the studio in Coyoacán I gave everything to Fede, Bruno’s assistant editor, a kid with a moustache he’s still waiting for. I gave him the raw takes, not the cleaned ones. I didn’t tell him why.

He listened on the big monitors. He listened on his own headphones. He listened to T09 three times, nodding along like it was cumbia.

“Está chingón,” he said. “Super dark. The low end on the hydrophone, uf.”

“Anything else?”

“Like what?”

“Under the water. Around nine minutes. A voice.”

He listened again, all twenty-two minutes, while I watched his face, and there was nothing on his face but a young man enjoying a good recording of a river.

Then I put on my own headphones, the same cans I have used for eleven years, with the left pad mended with tape, and plugged them into his machine, and pressed play, and she was there. Exactly where she had been. Closer, if anything.

I gave him my headphones. He listened. River.

I put them on again. Her.

It wasn’t the headphones. I tried his. I tried the monitors with my eyes closed and Fede outside the room. She was there whenever I was the one listening and nowhere when I wasn’t. She wasn’t in the files at all. She was in the act. In me, doing the thing I’ve done every day for fifteen years, leaning in, giving a sound my whole attention.

Fede asked if I was all right. I said I had a migraine. I took the headphones off and put them on the desk, and from the desk, tiny, the way headphones leak when you set them down, I heard her say Mati.

Fede didn’t look up.

* * *

So I stopped listening. That was the plan. It lasted four days.

You cannot imagine how much of a life is listening until you try not to. I wore foam plugs. I turned the television to subtitles. I mixed nothing, recorded nothing, told Bruno I had a family emergency, which was true. I stopped putting my ear to Mateo’s back when he was asleep to hear him breathe, something I’d done since he was born and never told anyone. I walked around the apartment like a woman wading.

It didn’t matter. She didn’t need me any more, or she didn’t need me as much. Mateo started bathing with the plug in and refusing to pull it. Then he refused baths. Then my mother came out of the kitchen on the Tuesday with a wet dishcloth in her hand and a strange look and said, “He was talking to the sink.”

“What was he saying?”

“Ya voy,” she said. “Like when I call him for dinner. Ya voy, ya voy, I’m coming.”

That night I took the plugs out and lay on the floor of the bathroom with my ear against the tiles by the drain, and I listened the way I listen for a living, with everything, and I heard the Río de la Piedad moving under eight lanes of traffic three blocks away, and over it, very close, nearly in the pipe under the tub, a woman calling the names of children in the dark and waiting after each one for somebody to answer.

She was not asking for Mateo, exactly. That’s what I understood, lying there. She was asking for an answer. She called and called, and in all those years, under all those rivers, almost nobody shouted back. Then one boy in Narvarte did, because he’s polite, because I raised him to answer when he’s called.

* * *

What I know how to do is build sound. That’s the whole of my skill. I can’t pray properly, I can’t fight anything, but I can give a scene exactly the thing it’s missing so nobody in the audience feels the hole.

I spent two nights cutting a track.

I have, on those four hard drives, fifteen years of children. You record a lot of children in this job. Schoolyards in Iztapalapa for a ministry ad. A birthday party in Tlacolula with a donkey piñata. A public pool in Acapulco on Semana Santa, four hours of it, for a telenovela that never aired. A choir rehearsal in Juchitán. Kids are walla. They are background. Nobody in the audience is supposed to hear a single one of them as a person.

And children, when someone calls them, say the same thing everywhere. Ya voy. Ahí voy. Aquí estoy. Voy, mamá. I’m coming. I’m here.

I searched every file for it. I found three hundred and twelve. I cut each one clean, matched the levels, gave them a little air so they’d sit in a river, and laid them out across forty minutes, overlapping, so that it sounded like the whole bank of the Atoyac was full of children answering at once from every direction.

I was careful about one thing. I made sure I didn’t know a single one of their names. When a mother on a recording shouted a name before the answer, I cut the name off. That felt important. I still think it was important. I haven’t gone looking to find out.

RIOATOYAC_ZIM_D9_T01 to T11.wav. 25 Feb. Night. Waterproof speaker on the stones, 2 m into the current. Boom (shotgun) on pole, headphones. Gain at max. Notes: playing YAVOY_MASTER.wav into the river. Listening.

I left Mateo with my mother and I gave her instructions: no baths, no sinks, if he goes near the drain put the radio on loud. I drove down again. Bruno thought I was getting him more river and paid for the hotel.

I went back to the first place, below Zimatlán, because that was where she’d first come. I went at night, which nobody does, because Bruno’s señor with the flashlight had been right about that. I set the speaker in the shallows, wedged between two stones. I put on my headphones, the old ones with the taped pad, and plugged them into the recorder, and plugged the shotgun into that, and turned the gain up past where any sane person would put it, so that I could hear the river breathe on the far bank.

Then I pressed play on the children.

For a while it was only them. Hundreds of small voices in the dark answering nobody. I listened past them. That was the hard part, to listen through three hundred and twelve children for one woman.

She came at the fortieth minute of the second loop. Far off at first, mostly echo. Then halfway. Then she was in the shallows, and the meters were climbing, and there was less and less river around her voice, and she wasn’t crying any more.

She was calling the names. And for the first time, after each one, there was an answer.

Ya voy. Aquí estoy. Voy, mamá.

I could have pulled the headphones off then. I know that. But she only exists if somebody is listening, and the children on my track couldn’t listen, they were just sound, and I didn’t know how long she needed. So I kept them on. I kept the gain up. I let her come all the way.

There is a point where a sound has no reflection at all. No room, no river, no distance. It’s not next to you. It’s not even in your ear. It’s where your own voice is when you talk to yourself.

RIOATOYAC_ZIM_D9_T12.wav. 25 Feb. 02:17. Notes:

That’s where the labels stop. I didn’t write anything in that one. I found it on the card a week later and the length on the file was four hours and eight minutes, which is longer than the battery should have lasted.

The doctors say acoustic trauma, bilateral, profound. They ask what I was exposed to and I say a river, and they write that down.

It isn’t silence, though. I wish it were. People imagine deafness as a switch. It’s a channel. There’s always one in the mix. Mine is water, low and heavy, rolling over stones below Zimatlán, day and night, a little louder when I’m tired. A tinnitus, the second doctor calls it, and makes a note that it is unusually complex.

Bruno used T01 in the film, the clean one from the first morning. It’s track twelve on the stems he sent to the mixer. River ambience. I read the reviews. People say the river is the best thing in it.

Mateo is fine. He takes baths again. He pulls the plug himself and watches the water go down and doesn’t talk to it.

He talks to me instead, all the time, more than he used to, standing very close with his hands on my face. He knows I read lips now and he tries to make his words big and slow. This morning at breakfast he climbed into my lap and put his mouth right against my ear, the way I used to put mine against his back, and he said something, and said it again, and waited.

All I could hear was the river.
