Out of Bounds was shot using a custom-built flashlight rig designed to create a narrow, fixed beam of light, which meant the camera setup was highly restrictive and space on set was extremely limited. All crew had to work carefully around the rig without disrupting framing or shadow lines, placing constraints on mic placement and movement. Additionally the film’s antagonist never appears on screen – but Rob wanted its presence to be felt through sound alone. The goal was to create a vocal design that was unnerving, textural, and unnatural—something that hinted at intelligence without resembling anything recognisably human or animal.
Production Sound Mixing
We managed all on-location audio during principal photography. The shoot was built around a custom flashlight-based camera rig, which created a narrow beam of light and required tightly controlled framing. We used a shotgun mic on a boom, working in close coordination with camera to avoid casting shadows or interfering with frame lines. The shooting space was small, so mic placement and movement had to be precise. We performed live mixing on set to ensure performance clarity and monitor for noise issues. Equipment setup was kept flexible to allow fast resets and minimal disruption to filming.
Sound Design
The presence in the film is never seen, but its voice plays a central role in building tension. We created a custom vocal design using a combination of synthesis and heavily processed animal recordings. Source material included growls, low breathing, and insect textures, which were layered and manipulated using granular techniques and pitch shifting. The final result was intentionally ambiguous—partially organic, partially synthetic—designed to feel present but never identifiable. The voice design was built to sit inside the soundscape, emerging from the shadows rather than being placed on top of the mix.
Dialogue Editing & Final Mix
In post-production, we mixed and edited all dialogue to support the film’s pacing and mood. The performances were physical and minimal, so the mix focused on clarity without flattening natural variation. EQ, gain shaping, and subtle reverbs were applied to match the spatial tone of each scene. The mix was handled with attention to timing and silence—allowing the soundtrack to carry tension without overfilling the space. The monster voice was integrated directly into the mix environment to maintain cohesion between character performance and sound design.
