AiFi · The technology

An SDK, not a pipeline change.

AiFi keeps every device in the room in sync, so you can add companion-audio experiences to your app: accessibility, multiview sound and surround. It runs alongside your player, so your streaming pipeline, DRM and CDN stay exactly as they are. Sub-10 ms, no new hardware.

What AiFi does not touch

Your pipeline & DRM

AiFi runs alongside your player, not in front of it. Your streaming pipeline and DRM stay untouched, and content arrives from your service exactly as it does today.

Bandwidth & CDN

The sync coordination between devices is lightweight and local, so AiFi adds no meaningful CDN or bandwidth load. You keep serving the streams you already serve.

Startup & playback

A lightweight SDK that runs alongside your player, with no measurable impact on startup time or playback latency. Your player stays your player.

Data & privacy

The sync runs on-device. Sessions are authenticated, and any exported data is yours, not locked to us: pipe it to your stack or AI tooling, including via an MCP server. You decide what's shared.

Architecture
AiFi architecture: content source and DRM unchanged, your player, AiFi SDK on the audio path, local sub-millisecond sync across a device mesh
Each device streams your content and runs your player; AiFi runs alongside and holds them all to one shared clock. Your pipeline, DRM and CDN stay exactly where they are.
How it works
1

Play as normal

Each device streams your content from your service, unchanged. Local or HLS, your pipeline and DRM stay in place.

2

AiFi runs alongside

The SDK sits with your player, not in front of it, handling timing and buffering and holding every device to a shared clock.

3

Devices lock to the clock

Every device stays aligned, under 10 ms. Nothing for the user to do, and no pairing.

4

One experience in the room

Synced companion audio on the devices people already have: surround, per-person tracks, accessibility and multiview sound.

Questions engineers ask first
Does it touch our DRM or streaming pipeline?

No. AiFi runs alongside your player, not in front of it. Your DRM, pipeline and CDN are unchanged; the asset arrives from your service as it does today.

Can we mine the data, or is it locked to you?

The session and device events are yours, exportable and not locked to us. Feed them into your own data stack or AI tooling, including via an MCP server, so nothing stays siloed with one vendor. You control what's shared; the sync itself runs on-device.

Which platforms do you support?

You integrate AiFi into your existing iOS, Android and web apps. The same sync engine already ships in our own apps in the App Store and Play Store.

How accurate is the sync?

Under 10 milliseconds, using dynamic latency correction. It doesn't depend on Bluetooth or WiFi pairing protocols or external speakers.

How much work is the integration?

A few lines of code. You don't rebuild your player; AiFi handles syncing, timing and buffering behind the SDK.

How is it licensed?

AiFi is a licensable SDK for streaming platforms. We'll scope a POC with your team under NDA.

Bring your engineers. We'll go as deep as you want.
