AiFi · Synchronised audio for music

Streaming made music solitary. AiFi makes it shared.

Every platform has the same catalog, and most listening happens alone in headphones. The experience around the music is the part you can own. AiFi syncs the phones in a room into one sound system, so listening becomes something people do together, in person. That is what drives retention, word of mouth, and a reason to choose you.

AiFi Listen Together
Listening becomes a shared moment again.

One tap brings the phones in a room into a single synced sound system, so a group listens together in person, same song, same instant, filling the space. People who listen together stay longer and bond with the app. This is the heart of AiFi, and everything else is built on it.

The growth engine

Every invite to join the sound pulls in another person. Anyone nearby joins by scanning a code, no app to install, and the non-users among them discover the service in the moment. That turns word of mouth into a measurable channel of new users.

Frequently Asked Questions

Got questions? We’ve got answers.
Explore some of the most common questions about AiFi, integration, and partnership opportunities.

How does AiFi connect devices?

  • Open AiFi in the browser, or inside your app.
  • Scan a QR to add every phone nearby.
  • AiFi syncs them to within a millisecond.
  • The whole group hears one shared sound system.

Why does AiFi sound better than a single device?

  • More power: One phone speaker can’t fill a space but several together create a powerful, room-filling effect.

  • Spatial sound: Multiple devices project audio from different directions, recreating a natural, immersive environment.

  • Balanced volume: Instead of one device straining at max volume (and distorting), multiple devices share the load at mid-level, producing cleaner, richer sound.

How does AiFi keep playback in sync?

Devices detect their positions and build a 3D spatial map. AiFi distributes channels accordingly, so sound comes from the correct direction, just like an orchestra pit.

Can AiFi create stereo and 3D sound?

Yes. AiFi technology can transform ordinary speakers into a coordinated sound system. By synchronizing multiple devices, AiFi enables true stereo playback as well as immersive 3D and surround sound. This means listeners don’t need special hardware, AiFi uses the speakers people already have to create a rich, spatial audio environment.

What happens if people move around?

AiFi adapts instantly. If a phone moves from left to right, it automatically becomes the right channel, while others adjust around it. The result: sound that always feels natural, no matter how the group shifts.

How does AiFi handle different hardware?

Not all devices are built alike. Some have stronger bass, others sharper treble. AiFi applies hardware-dependent EQ, synchronizing frequencies across all devices. Instead of a messy clash of sounds, you get a coherent, unified soundscape.

What’s the end result?

Natural, powerful, social sound. The more devices you add, the better it gets, stronger sound together.
