🎮 GAME PROJECTS
This is Conga is a humorous medieval-themed action game created during the LVL UP Game Jam.
I was in charge of the entire audio design, from composing the music to recording and designing sound effects. My approach blended playful instrumentation with expressive SFX to support the fast-paced and comedic nature of the game.
This project earned the Best Sound Award, recognizing the effectiveness and creativity of the audio work within the jam's time constraints.
The score was produced in Studio One, and all implementation was designed with real-time game dynamics in mind.

In this mobile game project, I developed an adaptive soundtrack using FMOD. The music dynamically changes based on the player's oxygen level — as the player runs out of air, tension layers are triggered. These tension elements are designed to play in randomized layers, creating a constantly evolving soundscape that intensifies the gameplay experience.
This system demonstrates my ability to implement interactive audio with real-time responsiveness, enhancing immersion through adaptive composition
🎧 ADAPTIVE HORROR SCORE – SICKA MANSION
🔊 Hall Ambient
A sound redesign and music implementation project developed in Unity for Sicka Mansion, a horror game prototype.
This exercise explores dynamic 3D audio using FMOD to create immersive and adaptive horror experiences. Music transitions and sound effects respond to in-game positioning and player actions, enhancing tension and narrative pacing.
🕹 Game Engine: Unity
🎧 Tools: FMOD Studio (3D spatialization, parameters, audio routing)

🎧 ADAPTIVE GAME MUSIC – ZELDA SCENE
🔊 Temple of Time – Exterior vs. Interior
A dynamic and adaptive music prototype inspired by The Legend of Zelda.
Although the piece was produced in Studio One, all transitions and musical behaviors were designed as if implemented in FMOD.
The score responds conceptually to player states such as exploration, combat, and location changes using vertical layering and parameter-driven logic.
This project showcases adaptive thinking applied to interactive music composition.
🔊Forest to Combat Transition
Woodwinds outside, strings inside. Music reacts to sacred space
Peaceful ambient shifts into high-tension combat seamlessly.
🎧 Rescoring Scene — Tesis sobre un Homicidio
This scene from the Argentine thriller Tesis sobre un Homicidio was rescored as a narrative exploration exercise. The music layers synthesizers and asymmetrical rhythmic motifs inspired by the flickering of police sirens, creating a subtle but persistent tension without interfering with the dialogue.
The goal was to build suspense progressively, using techniques that could also apply to interactive environments. Although this is a cinematic project, the aesthetic and technical approach aligns with principles used in video game music design.
🎥 TRAILERS & CUTSCENES
In this redesign project, I recreated all Foley and music for a short scene from WALL-E using only Studio One.
Every sound was recorded from scratch with objects found in my room — including plastic, paper, and metal — to simulate mechanical movements and environmental textures.
The result showcases my ability to integrate sound design and composition with limited resources, crafting a believable sonic world for animation
This short film blends rural Chilean folklore with psychological horror, portraying a haunting zombie tale rooted in the countryside.
I contributed to the original soundtrack as part of a collaborative team, taking an active role as composer of several original melodies and performer. My approach centered on improvisation and emotional depth, using processed cello techniques — such as delay, reverb, and bow hits — to evoke tension and unease.
I also interpreted a traditional Chilean folk harp, which I re-harmonized in a minor mode to suit the horror tone of the film.
The result is a culturally rooted score that combines acoustic expression with creative sound processing to support the film’s eerie atmosphere.
