Use case · Halloween yard haunt

A Synced Halloween Soundscape for Your Whole Yard.

One speaker on the porch doesn't haunt a yard. Home Audio Sync lets you hide old phones in the bushes, on the steps, and behind the tombstones — every one playing the same spooky loop in perfect sync. Trick-or-treaters get surrounded by sound, and a yard that howls as one films incredibly for a Halloween short.

01 — Why it works

One speaker on the porch
doesn't haunt a yard.

A haunt feels real when the sound comes from everywhere at once. Every old phone in your drawer has a speaker and WiFi — scatter a few around the yard, sync them, and the whole scene comes alive. No wiring, no outdoor speaker rig.

01

Hide phones around the yard, all in sync

Tuck old phones in the bushes, on the porch, and by the tombstone props. Every one plays the same soundscape on the same beat, so a whisper travels the yard and a thunderclap lands everywhere at once.

Old phones become spooky speakers

That drawer of dead-weight phones finally has a job. No app to install — just a browser and the loop you loaded.

No echo between the tombstones

A single loud speaker slaps and echoes across the yard. Synced phones surround visitors in seamless, directional sound instead.

Built for a Halloween short

A yard that howls in sync is the kind of thing people stop and film. Start a session, scatter the phones, hit record — the surround-sound haunt reads on camera in a way a single tinny speaker never will.

02 — How it works

Three steps.
Zero wiring.

No outdoor speaker rig, no extension cords snaking across the lawn. If an old phone still turns on and opens a browser, it can join the haunt.
