I’ve been tasked with creating a small, immersive audio installation for a historical society’s exhibit on local maritime trade, but I’m hitting a wall with the spatial audio. The room is a narrow, irregularly shaped former ship’s storehouse with stone walls, and my budget is only about $800 for the entire audio component. I have four small, battery-powered Bluetooth speakers I can use, but I need to create a convincing 3D soundscape of a bustling 19th-century dock—lapping water, creaking wood, distant hawker calls—that moves and shifts as visitors walk through the space. The main constraint is I cannot run any permanent wiring or fix anything to the historic fabric, and I have to set up and calibrate the whole system in one afternoon before the opening. I’m struggling to find software that can handle this kind of responsive, multi-speaker soundscaping on a laptop without a complex DAW setup.

Use a four-way Bluetooth transmitter with aptX Low Latency to drive all four battery speakers in sync, no wiring. Build four stems (dock sounds, creak, voices, water) and bake them into a single stereo mix with deliberate corner panning mapping to the booth. Trigger playback via a cheap PIR or contact sensor wired to a tiny microcontroller; add inexpensive acoustic panels to tame reflections; test and calibrate in an afternoon, staying under $800.
