Sync Your Christmas Light Show to Music — on Every Phone at Once.

Your display already runs to a soundtrack. The missing piece is getting that audio to everyone parked at the curb — without a low-power FM transmitter and a “Tune to 88.1” sign. Home Audio Sync puts the show's soundtrack on every viewer's phone in sync: they scan a QR code and hear the music the lights are dancing to.

01 — Why it works

The lights are synced.
Now sync the sound.

Your show already runs to a soundtrack. The hard part is getting that audio to everyone watching without a low-power FM rig and a sign telling cars which station to tune. Every viewer already has a phone — that's the receiver.

01

Your soundtrack, in sync on every phone

Post a QR code at the curb and every viewer opens the same audio stream. They all hear the track your lights run to, in step with each other — the driveway and the sidewalk are on the same beat, not a mess of overlapping phone speakers.

No FM transmitter, no station sign

Skip the low-power FM rig and the “tune your radio to 88.1” sign. A QR code at the curb does the whole job.

Driveway and sidewalk, in step

Everyone watching hears the same beat the lights are dancing to, with no echo drifting between phones across the yard.

Made for the light-show community

A display whose music everyone can actually hear films beautifully and gets shared. Perfect for the season — set it up once, drop the QR on your sign, and every visitor leaves with the full show in their ears.

02 — How it works

Three steps.
No radio dial.

No transmitter to license, no station sign to print, no viewer fumbling with a car radio. If a visitor has a phone with a camera, they can hear your show.
