Three Milliseconds of Delay

At four in the morning the air in Belén does not cool down even by mistake.

It just sits there, flattened against the clay tiles and the unplastered walls, thick as rice water. The blue three-bladed fan rotated over the formica desk with a tired rattle, taking an idiot pause every time its plastic neck reached the left stop. Salomé Jaramillo had her t-shirt glued to her shoulder blades and her eyes dry from staring at a progress bar that seemed frozen at ninety-four percent. Outside, the neighbor's yellow sixty-watt bulb illuminated an empty clothesline where a tangled plastic bag hung, inflating and deflating like a rotting lung.

The project was called demo_strings_v2_final_FINAL.wav. A commissioned piece of nonsense for a mattress commercial in Envigado that nobody would remember the next day, but it paid the internet.

She had spent the last three hours dealing with track seventeen, a digital patch that emulated a late-eighties analog synthesizer. She had downloaded the files from a Russian forum shut down years ago, packed in a passwordless compressed folder that came with a tiny text file, barely a handful of bytes signed by someone calling himself Takumi Nishimura. The text was written in atrocious English, full of corrupted Japanese encoding characters that opened as black rectangles in Notepad, but it explained with a sickly meticulousness how he had ripped the EPROM memories in an unheated warehouse near the Tama River in Kawasaki, before the company owner, a certain Goro Kurata, gave the order to send the prototypes to the shredder to collect the insurance on a bankrupt warehouse. Nishimura noted down voltages, serial numbers, and even the ambient temperature with the resigned devotion of someone taking inventory of a shipwreck.

Salomé scratched her left wrist, right where the elastic of her hair tie had left a red groove in her skin. Her nail polish had been chipping since Tuesday, a wine-red shade falling to pieces that she picked off with her thumbnail every time a render took too long.

"Is there any boiled water left?" asked Marcela from the gloom of the hallway.

Salomé did not turn around. She simply lowered the monitor's volume a bit.

"In the blue pitcher in the fridge," she said.

"That pitcher smells like onion, Salomé. You always put uncovered stews right next to it."

"Well don't drink any, dummy."

"I'm going to die of thirst because of you," Marcela murmured, opening the fridge door with a dry rubber squeak. The white light of the appliance illuminated her bare calves and a political campaign t-shirt three sizes too big. "Stop burning your eyes out with that. Tomorrow you have to go to Robledo to see your mom."

"It's almost done exporting. Go to sleep."

Marcela closed the fridge, took two noisy gulps directly from a chipped mug, and dragged her flip-flops back toward the back bedroom.

Silence.

Salomé swept her sweatshirt sleeve across the formica to wipe away the ring of moisture left by a glass of lukewarm soda. The fan kept spinning, clack, clack, clack, hitting the plastic stop.

The render reached one hundred percent.

A dull beep announced that the file was ready in the temp folder. Salomé put on her headphones; the foam of the cushions was so worn out it left small flakes of black vinyl stuck behind her ears whenever she used them for more than half an hour. She hit the spacebar.

The opening chord—an open C minor with a low-pass filter—came in just as it should. Warm, artificial, with that slight old-oscillator tremor she had calibrated by hand. But right at the end of the fourth measure, when the reverb should have faded into the emptiness of the stereo channel, there was a dry click. Digital latency. A tiny stumble.

It was three milliseconds of delay.

She hit pause. Put the cursor back at second twenty-two. Zoomed in on the waveform until the lines turned into a mountain range of discrete dots.

It wasn't a buffer error. It wasn't the usual crackle of the gray USB interface she had connected with a cable patched with masking tape. Between the left channel and the analog noise floor was a drawing that didn't correspond to the synthesizer's sine wave. It looked like a scrape. A tremor.

Perhaps if her brother were alive he would have told her to turn off the screen, that nobody pays three hundred thousand pesos for a synthetic string arrangement, but—

The software does not invent ghosts; it only repeats with too much obedience what someone left to rot in the memory.

The phrase wasn't hers. It was noted at the end of Takumi Nishimura's text file, or she had read it in an old sound magazine of her dad's, what do I know. But there it was, tucked beneath the chord.

Salomé opened the parametric equalizer. She turned on a high-pass filter at eighty hertz to clean up the fan's background rumble that sometimes leaked through the unshielded cables, and then applied a narrow bell, with a brutal gain of plus twelve decibels, sweeping the mid frequencies.

Outside, a dog coughed among the creek's brush and fell silent abruptly.

At twenty-four hundred hertz, the harshness took shape. It wasn't a ground loop. It was air passing through a human throat, a damp exhalation, tired, glued to a carbon microphone or a cheap journalist's recorder.

Salomé leaned over the keyboard, pressing the headphones against her temples with both hands.

The voice wasn't singing. It wasn't even trying to follow the track's pitch. It was a flat murmur, almost mechanical, dragged down by a fatigue that sounded like an untimely closed office and cigarette butts stubbed out in soda caps.

"Saiwai-ku, Horikawa-cho, san-ban-chi," the whisper spelled out in the left channel, separating the syllables with a bureaucratic dryness before getting lost in the magnetic tape's hiss. "Kurata..." and then a series of six-digit numbers that had no mathematical relation to the tempered scale.

Salomé dropped the headphones onto the desk. The left earpiece bounced against the formica, emitting a sharp hum while the equalizer needle kept dancing all by itself on the screen.
