One recognition platform
From source creative to an answer at the edge.
Signals gives teams a controlled way to build, version, distribute, and operate private audio-recognition catalogs.
Shared fingerprint engine
Database generation and device matching use the exact same Go implementation, keeping every hash aligned.
CONSISTENT BY DESIGNCompact in-memory catalogs
Hash-grouped posting lists are loaded fully into memory. No SQL queries, service calls, or network lookup at match time.
FORMAT V3 · ACRFImmediate recognition
Short microphone buffers vote on sound and offset together, producing useful results without waiting for an entire clip.
SOUND ID + OFFSETRecognition in the real world Build an offline project
Designed for the places connectivity cannot be assumed.
Keep raw listening data local while giving product and operations teams a managed catalog workflow.
ConnectionOptional
Store
Mobile
Broadcast
Broadcast monitoring
Recognize ads and creative variants from live television or radio captures without sending recordings to a cloud matcher.
Retail media verification
Confirm what played on in-store screens and speakers—even across locations with unreliable connectivity.
Mobile experiences
Embed private recognition inside Android apps for second-screen experiences, attribution, and interactive campaigns.
Connected devices
Run compact catalogs on edge hardware where latency, bandwidth, and data ownership matter.
A calm operational workflow
Three steps from media to recognition.
Add your creatives, keep everything organized, and publish a recognition-ready catalog when you are ready.
01
Add your media
Upload the audio and video your product needs to recognize. Signals prepares each creative for you.
02
Organize your catalog
Keep creatives, tags, and projects together in one workspace your whole team can understand.
03
Publish when ready
Create a release, add it to your product, and keep recognition content current as campaigns change.

At match time
No cloud lookup. No SQL. No audio egress.
The prebuilt fingerprint database stays in memory beside the native matcher. Captures never need to leave the device, and results arrive without a network round trip.

Control plane security
Private matching, governed operations.
The runtime is offline. The catalog workflow still has the identity, tenancy, and automation controls a real team needs.

Built for automation
Your catalog pipeline belongs in CI, too.
Use scoped write keys to add creatives and rebuild. Use read keys in controlled delivery jobs that fetch the latest catalog.

Technical FAQ
The questions engineering teams ask first.
Signals separates catalog operations from runtime recognition, so each side stays simple and accountable.
01Does recognition require an internet connection?+
No. The native matcher and prebuilt ACRF catalog run entirely on the device. The dashboard is used to manage creatives and build distributable catalog files.
02What is Offline detection?+
Offline detection is available now. Your media database and matcher run locally on a mobile, edge, or Linux device, so recognition continues without a network connection.
03Is Online detection available?+
Online detection is available on request for products that prefer cloud-assisted recognition, centralized catalog access, or server-managed matching.
04What is Live Channel detection?+
Live Channel detection is currently in beta. It is designed for continuous monitoring of broadcast, streaming, or other always-on audio channels.
05What does a match return?+
The engine returns the recognized sound ID and the estimated offset where the captured audio begins inside that creative.
06Can the fingerprint pipeline be changed later?+
Yes, but database generation and device matching must use identical parameters. Any algorithm or pipeline change requires re-fingerprinting and redistributing the catalog.
07How is catalog access controlled?+
Organizations support owner, admin, member, and viewer roles. Scoped read/write API keys can automate uploads, builds, and downloads without sharing user sessions.
