From the speaker to the screen in under half a second.
Phantone connects what your audience hears to what they experience next — automatically, privately, and at scale. Here's exactly how.
Step 1: The signal goes into your audio.
Phantone takes your audio — a pre-recorded ad, a live stream feed, a stadium PA announcement — and embeds an invisible signal before it plays. The signal is inaudible. The audio quality is unchanged. It works on any format: WAV, MP3, AAC, live PCM stream.

Step 2: It plays. Anywhere audio plays.
The PA announces halftime. 60,000 people hear it. 60,000 phones are now eligible for the offer — only those who were actually there.
The ad break airs on ESPN. Every household that heard it is logged. Not estimated. Logged.
The sponsor spot plays at 8:47am on the morning drive. iHeart knows. You know. Your agency knows.
The opening act walks on stage. A signal fires in the PA. Verified fans in the venue get exclusive content. People watching the livestream get a different offer.
Your TV spot airs in Detroit. A listener's phone — tuned to your brand app — shows a dealer offer for the nearest Ford dealership.
Step 3: Something happens for the person who heard it.
The Phantone SDK lives in your brand app, your team's official app, your loyalty program, or a partner app. The moment the signal is decoded — in under 500ms — you decide what happens next.
You configure the recipient experience in the Phantone dashboard. No engineering required for changes. What triggers is entirely up to you.
These can all fire simultaneously. Configure one or all three per campaign.
A personalized discount, exclusive to listeners who were actually in the room — or tuned in. No coupon code. No scanning. The sound was the trigger.
Step 4: You see everything.
The Phantone dashboard gives you a real-time feed of every verified impression — not a sample, not an estimate. Every device that heard the signal, every experience that fired, every timestamp. Your agency gets the same data. Your DSP gets the webhook. Your CRM gets the event.
See it in your world.
