AI Translation Summary
A sound never recorded, restored 80 years later. 'Hearing 1945' by BINGGRAE uses AI — disciplined by historians, not left to invention — to reconstruct the roar of Korea's Liberation Day, August 15, 1945. Every detail of the campaign bends to the number 8.15: eight minutes fifteen seconds of audio, an 8.1-channel mix, 815-won tickets whose profits went to the families of independence activists.
Cultural Context
Liberation Day (Gwangbokjeol) marks August 15, 1945, when Korea was freed from 35 years of Japanese colonial rule. Because recording technology was suppressed under that rule, no audio of the day survives — only photos and text. The campaign turns the date '8.15' into its entire structure: 8 min 15 sec of sound, an 8.1-channel system, 815-won ticket prices, and an 8:15 AM release.

Summary
[Bringing Lost History to Life Through AI Sound] 'Hearing 1945' is an immersive sound experience restored with AI, recreating the roar of August 15, 1945, Liberation Day. Because audio recording technology had fallen behind under colonial rule, sounds of that day were never preserved; only texts and photographs remain. To restore the sound, it went through historical accuracy verification without embellishments. Every sonic clue, from on-site noise to period accents, was cataloged with keywords. Using these keywords, individual sound elements were generated and mixed after simulations reflecting crowd size and environment. For the 80th anniversary, 'Hearing 1945' was released in special theaters and two history museums, allowing audiences to experience the moment as if present in 1945.
Strategy
[The Most Powerful 8.15] Our goal was clear: to reignite the significance of Liberation Day. The execution was strategically tailored to 8.15 for maximum impact. 8 minutes and 15 seconds of immersive sound content was released on August 15th in theaters with an 8.1 channel system for specialized direction and sound immersion. Tickets were sold for 815 Korean Won, and the profit was donated to support the descendants of independence activists. The production documentary was released on YouTube at 8:15 A.M. On August 15th, two history museums displayed the immersive sound exhibition. Intriguing the curiosity for the sound of liberation, 'Hearing 1945' went viral, resulting in a higher theater occupancy rate and history museum visitors than the average of the 2025 Liberation Day Season.
Execution
[Against the Era of AI Slop: Historically Grounded AI Usage] To restore the roar of Liberation Day from 80 years ago, we didn't simply generate sound based on imagination or typical AI deepfakes. Instead, the lost sound was reconstructed with AI through rigorous historical accuracy verification based on existing data. Photographs, written records, and survivor interviews were collected with historians, catalogued by time and location, then classified into keywords. Based on these keywords, prompts were written and individual sound sources were generated. Decibel levels were determined through simulations reflecting crowd size on the day of liberation. All sound sources were mixed into a cohesive soundscape structured as a narrative, recreating Liberation Day as faithfully as possible.
