AiryMedia Inc. provides this solution. We are a subsidiary of Evixar Inc., No.1 in acoustic communication technology.
As provenance verification and misinformation countermeasures become essential in advertising and promotion, Evixar holds Japan's only algorithm for C2PA soft-binding — invisibly tracking content provenance information without any perceptible change to the audio.
Sound triggers are far easier to understand by experiencing once than by reading about it.
The demo below uses 2 devices — PC plays the sound → Smartphone's microphone picks it up and the screen reacts.
＊ This demo opens the receiver page via a QR code for convenience — purely to launch a browser page.
In production, the real work is embedding the receiver into the places your users already are — your existing website, native app, or LINE mini-app. That embedding design is the core of the experience. AiryMedia provides end-to-end design and implementation support for this (consult us).
Play the video on PC, and the demo site on your phone responds
📱 Scan this QR with your phone
💻 Play this video on PC
Play different sounds on PC → different things land in your phone's LINE
💻 Play one of these on PC (each sound delivers something different)
Same LINE account, but what's delivered changes with each sound (embedded ID). This is the "1 audio source = diverse experiences" of the Audio Watermark method.

Venues, broadcasts, stores, street corners — sound-activated experiences emerge from any audio.
Voting, quizzes, and product links launch on viewers' smartphones via audio trigger from TV or CM audio. Create CM-linked campaigns and "watch and participate" second screen experiences.
All audience smartphones respond simultaneously to speaker audio — no app required. Synchronized delivery of cheering lights, special effects, and information.
Sound-activated audio trigger converts CM or outdoor signage audio directly into coupon acquisition or product pages. Capture the "moment of viewing" as a sound-activated ad.
Distribute digital items or exclusive content triggered by station, airport, or train announcements. Design app-free experiences unique to "that place, that moment."
A new input source for contact measurement alongside QR codes, geofencing, and BLE. Integrate via API into measurement apps, MMP, CDP, or analytics tools — providing a unique complement: "invisible to the eye, detectable by sound."
Use cinema soundtracks, live venue BGM, or TV commercials as triggers to fire real-world synced events only for players who were there — limited-item drops, special boss appearances, collab event unlocks, and more.

AiryMedia Trigger offers 2 acoustic communication methods. Choose based on whether you can process the audio source yourself. Both methods can be combined.
Recognize existing sounds as-is
Identifies sounds from their acoustic characteristics without modifying the source. The key strength: sync with sounds you don't control — TV broadcasts, existing music, third-party audio.
💡 No original audio file? No problem. Create recognition data by recording near the speaker during playback. Past broadcasts, venue-exclusive sounds, third-party music — register without the official source in hand.
Best for
Embed an "ID" in the sound for reliable delivery
Embed an inaudible ID into the audio source in advance. The ID is decoded instantly on playback — working reliably in scenes where you control the audio.
💡 Same audio source, different IDs, different behaviors. Campaign A/B switching, different coupons per store, region-specific productions — create diverse experiences from a single audio source.
Best for
💡 How to choose: If you can process the audio source → Audio Watermark. If not → Fingerprint. Combining both is also possible.

Proven deployments across sports, entertainment, and B2B sectors.
As part of the Toyota Mobility Foundation "Mobility for ALL" proof-of-concept, deployed a smartphone penlight experience in an arena of 10,000+ attendees. Achieved stable operation under thousands of simultaneous connections, uniting fans and the venue through sound and light.
In-venue audio triggers a lottery on each attendee's smartphone, with winners collecting prizes inside the stadium. A single event attracted around 17,000 participants — a flagship example of the "Trigger Count" model, where reach, entries, and prize redemptions can all be counted as actual numbers.
Deployed as the "Smartphone Cheer" experience. Using web-based technology with no dedicated app required, thousands of spectators participated in real-time synchronized production — delivering an inclusive entertainment experience.
First deployment of the smartphone penlight experience for a T.League team. Delivered end-to-end fan engagement, including post-game follow-up via the official LINE account.
Synchronized with in-theater audio to deliver commemorative digital illustrations to audience smartphones in real time. Penlight auto-control was also activated during special screenings — a new form of premium content distribution using audio as proof of presence.
Licensed acoustic communication technology to Shachihata for integration into their own service under their brand.
