He Took the BAFTA Nomination for My Sound Design — Then the Moderator Asked Him to Solo the Leviathan Stems Live

He took the BAFTA nomination for my sound design — then the masterclass moderator asked him to solo the stems.
Sia Lin was in Studio B at 3:07 AM on a Thursday in March when she found the sound.
She had been looking for it for six days.
The sound was the Leviathan roar — the primary acoustic signature for the creature at the center of Deep Trench, a $180 million sci-fi feature that had been in post-production for eight months.
The director, Paul Vance, had described what he wanted in a single line in his notes: “The sound of something ancient coming up from a place where light doesn’t exist.”
This was not a useful technical specification.
Sia had treated it as a creative brief.
She had spent six days in the studio trying combinations.
She had tried sub-bass oscillators.
She had tried processed whale calls.
She had tried slowed-down industrial recordings.
None of them were right.
On the Thursday, she had borrowed a cello from the session musician down the hall.
She had requisitioned 8kg of dry ice from the lab supply office.
She had the cello in the isolation booth at 2:40 AM.
She had set the bow on the string.
She had drawn the bow across the string slowly, with maximum rosin contact, while Leo — her recording assistant, 25, who was there because she had texted him at 1:30 AM and asked if he wanted to hear something interesting — held the microphone two inches from the contact point.
The string resonated at a frequency that was technically inaudible but felt physically present.
She did it again.
She ran the recording through the Neve desk.
She added the low-frequency oscillator she had tuned to 18Hz — below the threshold of human hearing but within the range of physical sensation in a cinema seat.
She played it back.
Leo said: “That’s it.”
She said: “The cello on dry ice reduces the bow contact friction. You get a different harmonic blend. The LFO underneath pushes it into the body.”
She said it the way she described any technical methodology — as information, not as a discovery announcement.
She played it again.
It was the sound.
She built the Leviathan roar in three more hours: the walrus vocalization for the upper mid-range, the cello recording for the foundation, the LFO for the physical sensation layer, a time-stretched orchestral hit at the tail for the sense of mass.
She routed it through Tracks 14, 22, and 41 in the session file.
She put it on the stem sheet.
She labeled the tracks.
She put the headphones on.
The weighted headphones sat on her neck when she wasn’t mixing — she wore them there the way some people wore lanyards.
The left cable had been fraying at the connector for two years.
She had wrapped it in black gaffer tape at the repair point.
The tape was starting to peel at the edges.
She would re-tape it when it failed.
She put the headphones on her ears.
She played the Leviathan roar in context with the picture.
On the screen, the creature broke the surface.
The sound came through the headphones at full mix level.
Julian Cross was Sia’s supervising sound editor and department head.
He was 50 and had been in post-production for 25 years.
He did the final 5.1 surround mix.
He attended the director reviews.
He approved the stem sheets.
He managed the department’s BAFTA nominations paperwork.
The day Paul Vance had heard the Leviathan roar in the mix review, Julian had been sitting next to the director.
The director had said: “That. That sound. How did you get that low end?”
Julian had said: “We spent weeks getting it right.”
He had not looked at Sia.
He had said “we” because Sia was in the department and the department was his, and in twenty-five years of post-production he had communicated sound design to directors as a department output, not as an individual attribution.
He had believed this was accurate.
He had believed the final mix was the design and he had mixed it.
He had not examined whether mixing a recording and making the recording were the same act.
Sia was at the back of the room.
She did not correct Julian.
She was the Foley Assistant on paper.
He was the Sound Designer on paper.
She had accepted the titles at the beginning of the engagement because she was ten years into post-production and she understood how department hierarchies worked.
She had not anticipated what would happen with the titles when the nomination paperwork went out.
The BAFTA nominations were announced on a Tuesday morning.
Deep Trench: nominated for Best Sound.
Official nomination: Julian Cross, Sound Designer.
Sia read the press release at her desk in the studio.
She took off the headphones.
She placed them on the console in front of her.
She looked at the frayed gaffer tape on the left cable.
She looked at the headphones for a moment.
She did not pick them up.
She left the studio.
(Drop “SIA” in the comments if you want to see what happened at the BFI masterclass.) 👇
Director Paul Vance posted his congratulations to Julian on Twitter at 8:54 AM the morning of the announcement.
“Incredible work by Julian Cross and the sound team on Deep Trench. Julian’s singular vision for the creature’s acoustic identity is what made this film. BAFTA nod is well deserved.”
Sia read it on her phone.
She was standing in the studio carpark.
She had come back to get her keys.
She read “Julian’s singular vision.”
She read “acoustic identity.”
Julian had not invented the acoustic identity.
She had invented it alone in an isolation booth at 3:07 AM with a borrowed cello and 8kg of dry ice.
She put her phone in her pocket.
She went back inside.
She picked up the headphones from the console.
She set them around her neck.
She went to her desk.
She had a new foley session starting at 10 AM.
She opened the session.
She labeled the first track.
She went to work.
There had been a morning four months before the announcement, when Paul Vance had come to the mixing stage for a playback review.
Julian had been at the desk.
Sia had been at the back of the room with the stem printouts.
The director had asked Julian: “The underwater sequences — when the creature moves without showing itself. What are we doing for the pre-appearance acoustic cues?”
Julian had said: “We’re building a pre-sequence pressure layer. Low-frequency build with a mid-range harmonic that drops out just before the reveal.”
He had been describing an email Sia had sent him three weeks earlier.
She had written: “For the pre-appearance cue, sub-100Hz pressure build using the LFO under a harmonic drone. We strip the mid-range in the six seconds before the creature breaks frame. The absence creates anticipation.”
Julian had replied with a thumbs-up.
He had described it to the director as “we’re building.”
He had not said “Sia proposed this.”
She had been in the room.
She had been introduced to Paul Vance once in fourteen months.
They had been in the kitchen.
He had said: “Hi, sorry — you’re Julian’s assistant?”
She had said: “I’m the Foley Designer.”
He had nodded and taken his coffee and left.
He had not remembered.
He had written “Julian’s singular vision” in his tweet and not known her name.
She had accepted, for fourteen months, that the director did not know her name.
She had accepted that the credit would sort itself out at the BAFTA form.
She had been wrong about the form.
The British Film Institute masterclass was three weeks after the announcement.
Listed: “Inside Deep Trench — The Sound of the Abyss.” Featured speaker: Julian Cross, Sound Designer.
Sia bought a ticket at 11:17 PM the night the event was listed.
She did not tell Julian.
She sat in row 4.
The headphones were in her bag.
She had been to industry events with headphones in her bag for ten years.
Julian took the stage.
He spoke about “texture” and “the emotional register of the creature’s soundscape.”
He had spoken for eighteen minutes when the moderator asked: “Can you strip away the layers for us live? Show us how the sound was built?”
Julian said: “Absolutely.”
He muted the master.
He reached for Track 14.
Sia’s bag was on the seat beside her.
She knew what Track 14 was.
She had labeled it: “Leviathan_Cello_DryIce_01.”
She watched Julian click it.
A distorted synth pad filled the theater.
It was not the cello.
It was a rejected texture from month 3.
Julian looked at the screen.
She looked at the moderator.
She looked at the 300 professionals in the room.
She had her hand on the bag strap.
She waited.
Julian had spoken with complete authority for eighteen minutes.
He had discussed the conceptual development of the creature’s soundscape.
He had discussed his conversations with the director about emotional register.
He had discussed the mixing process — the way he had blended the elements in the 5.1 surround environment to create a sense of depth in the theater.
All of this was accurate.
He had had those conversations.
He had done that mixing.
The mixing had been done on top of a recording architecture that he had not built and could not navigate.
He had operated on top of Sia’s work for fourteen months without understanding that operating on top of something and building something are different activities with different relationships to authorship.
He understood this now because the moderator had asked him to demonstrate and the track was not where he thought it was.
He was looking at 150 tracks in a session that was organized in a logic he did not know.
He clicked Track 18.
Ocean noise.
He clicked Track 23.
A synth hit, hard left.
He clicked Track 27.
The theater heard a room tone from a recording session that had been scrapped in November.
The silence between wrong tracks was getting louder.
It was the kind of silence that professionals fill with their understanding of what they are watching.
No one spoke.
No one needed to.
Julian was at the desk.
He was looking at 150 track labels in the Pro Tools session.
He was looking for the cello.
A 150-track session is built over months.
Tracks accumulate.
Rejected takes stay in the session.
The session was organized in Sia’s organizational logic.
Instrument type, recording date, layer function.
She had labeled every track when she created it.
The labels were clear if you had created them.
If you hadn’t created them, they were a wall of text.
Julian had loaded the session that morning to prepare for the masterclass.
He had found the master output.
He had checked the final mix was intact.
He had not traced the individual stems.
He had assumed he could locate them when the time came because he had heard them thousands of times.
Hearing a sound and knowing where it lives in a session file are different kinds of knowledge.
He was at the desk understanding this distinction in front of 300 people.
He found an ambient ocean noise track.
He clicked it.
Ocean sound filled the theater.
The moderator said: “That’s the ambient layer?”
Julian said: “Yes — this is one of the environmental textures. I’m looking for the creature’s foundation recording.”
He clicked through three more tracks.
He found a distorted synth hit.
He found a click track.
He found an early draft of the orchestral tail that had been replaced in month 6.
The crowd was quiet.
The BFI theater held 300 industry professionals.
Post-production supervisors.
Sound designers.
Foley artists.
Mix engineers.
People who had spent careers building sessions exactly like this one.
They knew what it looked like when someone couldn’t find a track they hadn’t built.
The silence in the room was not empty.
It was informed.
Julian looked at the track labels.
He looked for any label that said “creature” or “roar” or “Leviathan.”
The session used Sia’s naming convention.
The creature tracks were labeled by their organic source: “Cello_DryIce_01,” “Walrus_Mid_01,” “LFO_18Hz_01.”
Julian did not know that the dry ice cello was the creature’s foundation.
He knew he had approved it.
He had pushed the master fader when it was in the mix.
He did not know its name in the session file.
He had been in his eighteenth second of silence.
He said: “Sia — can you come up?”
He said it into the microphone.
He was looking at the fourth row.
She was already standing.
She had been standing for twelve seconds when he said her name.
She had not needed to hear her name.
She walked up the steps to the stage.
Leo, the mix tech, was at the side of the stage.
He handed her the mouse without her asking.
She did not look at Julian.
She looked at the track labels.
She found Track 14 in two seconds: “Leviathan_Cello_DryIce_01.”
She solo’d it.
The cello on dry ice filled the theater.
She solo’d Track 22: “Leviathan_Walrus_Mid_01.”
The walrus vocalization layered in.
She solo’d Track 41: “Leviathan_LFO_18Hz_01.”
The low-frequency oscillator hit the speakers — inaudible as a tone but present as a physical sensation in the cinema seats.
The Leviathan roar built across three tracks.
It filled the BFI theater.
Three hundred industry professionals sat in their seats and heard the sound that had been nominated for Best Sound at BAFTA, coming from three tracks that a woman had labeled herself and found in under ten seconds.
The moderator watched.
She was looking at the track labels.
She was looking at Sia.
She said: “And you are?”
Sia said: “Sia Lin. Foley Assistant.”
She walked down the steps.
She walked out of the theater.
Leo was smiling at the side of the stage.
Julian was at the desk.
The Leviathan roar was still playing.
Outside the BFI theater, Leo was folding up the cable at the side-of-stage desk.
He had watched 40 seconds of Julian clicking wrong tracks.
He had watched Sia stand up from the fourth row before her name was called.
He had already had the mouse in his hand when she reached the stage steps.
He handed it to her.
He watched her find the first track in two seconds.
He watched her find all three in under ten seconds.
He watched her step back.
He watched the Leviathan roar fill the theater.
He said nothing during any of this.
He was the mix tech.
He was 25.
He had been in the room at 3:07 AM when she found the sound.
He had been the one holding the microphone two inches from the cello string.
He had been in the room for 14 months.
He knew whose map this was.
He folded the cable.
He coiled it.
He set it on the desk.
The roar was still playing.
Julian had found the master output.
He had muted it.
The theater was quiet again.
The clip had been recorded on three different phones by three different people in the fourth row.
It was online by 11:30 PM that night.
By the following morning, it had been shared 40,000 times.
The clip showed: 40 seconds of Julian clicking through tracks. Three wrong sounds — ocean noise, a distorted synth, a click track. Then a woman in the fourth row standing up before her name was called. Her walking to the stage. A mix tech handing her the mouse before she reached for it. Three track solos in under ten seconds. The Leviathan roar filling the theater. “And you are?” “Sia Lin. Foley Assistant.” Walking out.
Sound Twitter called it the most significant 90 seconds in BAFTA season.
Post-production forums shared it.
Thread titles ran variations on the same observation: “She knew every track number without looking at the labels.” / “She was standing before he said her name.” / “Note how she doesn’t say anything to him when she leaves.”
The clip reached 150,000 shares by the following afternoon.
The BBC sound department linked to it.
Three post-production studios asked Julian for comment.
He gave none.
He was reading the threads from his phone in his car in the BFI parking structure, having sat there for 40 minutes after the masterclass ended.
He understood that 300 industry professionals in a theater had watched him fail to locate a recording he had submitted as his design.
He understood that the video of it was now the most-watched clip in the British sound design community.
He understood that every professional who watched the clip was making the same observation: the person who pulled three tracks in under ten seconds had built the session. The person who couldn’t find the track in 40 seconds had submitted it.
He had spent six years in senior supervision.
He had been in the final mix for 25 years.
He had believed that the final output was the design.
A session file is not a final output.
A session file is a map of how the output was built.
He didn’t know the map.
He had pressed the faders on top of it.
He had said “we.”
He was sitting in his car at 10:47 PM understanding what “we” had meant.
He texted her at 11:58 PM, before he had decided what to do.
He typed: “I couldn’t find the routing.”
She replied: “I know.”
He read her reply.
He put the phone on the passenger seat.
He drove home.
He lay in the dark at 1 AM.
He was not going to sleep.
He understood that he had to file the BAFTA petition in the morning.
He understood that it would not fix the 40 seconds that was already on the internet.
He understood that the 40 seconds was its own record, separate from whatever correction he made.
He understood this was not the same as the correction being unimportant.
He did the math on what he needed to do.
He fell asleep at 2:30 AM.
He came into the studio at 8:30 AM.
He was carrying his laptop and a coffee.
He sat across from Sia at her desk.
He said: “I submitted the BAFTA correction last night. I’m petitioning for a credit amendment.”
She said: “Okay.”
He said: “The nomination will be updated to Co-Sound Designer. Your name will be on it.”
She said: “Okay.”
He said: “If we win, I’ll address it in the speech.”
She said: “Okay.”
He said: “I should have structured the credit differently from the start. The final mix is a separate function from the design. They’re not the same thing. I should have known that before I signed the paperwork.”
She said: “Yes.”
He said nothing else.
He stood up.
He said: “Paul Vance called me this morning. He asked specifically for you on his next film. Not the department. You.”
She said: “I’ll call him.”
He said: “Lead Designer.”
She said: “Okay.”
Julian left.
She looked at her session file.
She opened a new track.
She labeled it.
She had work to do.
The BAFTA correction was confirmed four days later.
The nomination was amended: Julian Cross, Sound Designer. Sia Lin, Co-Sound Designer.
She received the official BAFTA letter at her home address.
It confirmed that a secondary bronze mask would be minted with her name.
She read it.
She put it on her console.
She did not frame it.
It sat next to her coffee cup.
Julian stood up at the BAFTA podium three months later.
He held the trophy.
He said: “I mixed this film. Sia Lin designed the sounds you heard. She built the Leviathan from cello strings and dry ice at three in the morning. She is the architect of what you felt in your seats. This belongs to her.”
He said it.
He said it in front of 2,000 people in the Royal Festival Hall.
She was in the room.
She was sitting at a round table at the edge of the floor.
She was wearing the headphones around her neck.
She was not looking at the stage.
She was looking at the program on the table.
She heard the words.
She did not look up.
He had said it.
She had already known it.
The knowing had been there for a long time.
The saying of it was his.
Both could be true.
The three threads that were shared most widely were from people who had been in the theater.
The first said: She found three tracks by number without looking at the labels. He had 40 seconds with the mouse. She had 8.
The second said: She was standing before he called her name. She already knew.
The third said: She said ‘Foley Assistant’ and walked out. That was the whole speech.
The threads ran to thousands of replies.
People in post-production recognized the session navigation.
People outside post-production recognized the dynamic.
Sia read none of them.
She had turned her phone off at 10:30 PM.
She was at home.
She was reading a book.
She had the headphones on the table beside her.
She was not thinking about the theater.
She had done the thing that needed doing.
She had found the track.
She had walked out.
The rest of it was other people’s work.
Julian was doing his work.
She would do hers.
She turned the page.
She did not draft a statement.
She did not prepare a response to the threads.
She had said what she needed to say in the BFI theater: ‘Sia Lin. Foley Assistant.’
Everyone in the room had heard it.
The video had transmitted it to everyone who hadn’t.
Her name was in the sound now.
The bronze BAFTA mask was delivered to her studio three weeks after the ceremony.
It arrived in a padded box with a card from the BAFTA organization printed on heavy cream paper.
She opened the box.
She read the inscription: Sia Lin, Co-Sound Designer, Best Sound, Deep Trench.
She set it on the shelf above her desk.
She went back to the session.
The new indie film was called The Lichen Protocol.
It had a budget of $2.4 million.
It had a sound concept that interested her: the score was built from organic field recordings — no synthesized instruments, no electronic processing.
She had agreed to design it before the BFI masterclass, when she was still a Foley Assistant on paper and a Sound Designer in practice.
She was the Lead Sound Designer on paper now.
Paul Vance had asked for her specifically for his deep-sea follow-up.
He had called Julian the morning after the masterclass.
He had said: “I want Sia as the Lead Designer. Not Co-Designer. Lead.”
Julian had said: “That works.”
Julian had called her at 8 AM.
He had said: “Paul wants you for the follow-up. Lead Designer.”
She had said: “I’ll call him.”
She was working in the same studio.
The same desk.
The same dark mixing stage with the glowing screens.
The session for The Lichen Protocol was three weeks old and had 60 tracks.
Each track labeled in her organizational logic: instrument type, recording date, layer function.
Every track had been created by her.
Every track name was a word she had chosen.
The session was legible to her the way her own handwriting was legible.
She reached up and put the headphones on her ears.
The left cable had a new section of gaffer tape on it.
The old section had finally peeled fully off, and she had cut a fresh strip from the roll on the console.
The new tape was whiter than the old tape.
Brighter.
Still smelling faintly of the adhesive.
She had been re-taping this cable for three years.
In six months the new tape would be the same color as the old tape.
She would tape it again after that.
The headphones were not fixable in any permanent way.
They were weighted exactly right.
She had owned them for ten years.
She had paid for them herself at the start of her second year in post-production, when she understood that she was going to be spending thousands of hours monitoring.
The left cup had a slightly different frequency response from the right cup now, after ten years, and she had adjusted her monitoring habits to account for it.
She pressed the left cup against her ear just slightly tighter than the right.
She had done this without thinking for two years.
She knew their curve.
She reached up and pinched the gaffer tape connector through the new tape.
The connection held.
She pressed play.
A field recording of lichen growth filled her ears — forty-eight hours of time-lapse audio from a forest floor, sped up to create a ten-second texture of organic movement.
She listened to it.
She held the fader.
She pushed it up 2dB.
She listened again.
She was building a new thing.
Julian stopped by the studio at 5:30 PM.
He said: “Paul confirmed you as Lead Designer. The contract will go directly to you.”
She said: “Good.”
He said: “He also said he wants to see you at the concept review next week.”
She said: “I’ll be there.”
He said: “Same structure — you design, I mix what you build.”
She said: “Same structure. Different credit.”
He said: “Different credit.”
He left.
She had stopped expecting him to say anything else.
He was doing what was available to him to do.
She was doing what had always been available to her.
The official film credits of Deep Trench — the DCPs, the theatrical release prints, the Blu-Ray master — still listed her as Foley Assistant.
The DCP files had been distributed to 4,200 theaters in 63 countries before the masterclass.
They could not be updated without re-mastering the entire distribution chain.
The IMDb page had been corrected.
The BAFTA official records listed her as Co-Sound Designer.
The theatrical celluloid was permanent.
She knew this.
She had read the BAFTA letter three times.
The letter said Co-Sound Designer.
The celluloid said Foley Assistant.
Those two documents would exist simultaneously in perpetuity.
She was not going to explain the sequence to anyone.
She was not going to explain which document came first or which one was authoritative.
She picked up the headphones.
She pinched the gaffer tape.
The frequency held.
She turned off the light at 11:15 PM.
She put the headphones on the nightstand.
She went to sleep.
She did not have a resolution.
She had done the thing that needed doing.
That was enough.
