AiFi brings to your business
Intelligent Audio Infrastructure for Streaming Platforms
At the core of Sound Dimension is AiFi, (Artificial-Intelligence Fidelity) a software-driven, patented audio engine built to redefine how sound behaves across mobile devices.
AiFi mobile audio technology uses advanced real-time AI to intelligently analyze the environment, content type, and speaker configuration on the fly.
By leveraging the microphones and speakers already present in smartphones and tablets, AiFi turns any group of devices into a spatially aware, self-optimizing sound system. No pairing. No calibration. Just adaptive, high-fidelity audio that evolves with your users.
Designed for seamless integration via SDK, AiFi enables streaming platforms to get immersive, room-filling sound experiences without additional hardware. Check out how it works in this demo.
Seamless Multi-Device Audio with AiFi
1. Your music stream comes from the normal place
A user presses play in their regular player app. The music arrives from the streaming service just like it always does.
2. AiFi creates a shared sound experience. On the leader phone, AiFi organizes the audio so it can be shared. It takes care of timing, buffering, and distribution. The phone keeps playing music normally, but it also sends small sync signals to the other phones nearby.
3. Other phones join in instantly
When another phone joins the session, AiFi handles the tricky parts behind the scenes:
-
syncing volume
-
syncing audio
-
syncing timing
-
managing buffering
The user doesn’t have to do anything. Their phone simply “locks in” to the leader phone.
4. All phones turn into one big speaker system. Once connected, every phone plays the same music at the same moment. The sound becomes louder, fuller, and more immersive, just by using the devices people already have.
5. No special hardware. No extra bandwidth. No hassle.
AiFi uses the phones’ existing connections (Bluetooth, WiFi, or mobile data) to stay perfectly in sync. Everything happens locally between devices, so it’s fast, efficient, and reliable.
AiFi is a smart player. It handles syncing and timing across phones, so users get a richer, shared sound experience with zero effort. Read the documentation here.
AiFi SDK: Add Social Sound to Your App in Minutes
The AiFi SDK is the easiest way for streaming platforms to enable shared listening. AiFi player takes care of all the complex parts automatically.
With just a few lines of code, your app gains the ability to:
-
sync phones in real time
-
align volume, audio, and timing
-
create one shared listening session across users
-
boost playback quality using the phones already in the room
Developers don’t need to rebuild anything.
Users don’t need to learn anything new.
Your app gets a powerful new social and immersive feature, and your audience gets a richer, more engaging listening experience.

Our Innovation Journey
Sound Dimension has pioneered a range of cutting-edge technologies that deliver pristine, immersive audio experiences. By redefining the dimensions of sound—depth, width, and height—we achieve unprecedented clarity and spatiality. Whether you’re listening to an audiobook, your favorite music, or an immersive movie soundtrack, Sound Dimension ensures your content is always delivered with authenticity and precision.
Our journey builds on the legacy of Alan Dower Blumlein, the father of stereo, who in 1933 demonstrated how the distance between loudspeakers influences the perceived sound image. Leveraging Blumlein’s foundational insights, we have made a quantum leap forward by integrating advanced binaural research with modern speaker array physics and design.
Grounded in the physics of loudspeaker reproduction and the science of human auditory perception, Sound Dimension specializes in delivering exceptionally accurate mono, stereo, and surround sound—all from a single loudspeaker enclosure. Our approach returns to the basics of binaural sound reproduction, emphasizing driver separation of around 17 cm or more to create an immersive soundstage that fills any room.
With Sound Dimension technology, even a standard stereo Lt/Rt signal can be transformed into a high-quality home cinema experience. By mastering the tonal, dynamic, and spatial dimensions of sound, we extend loudspeaker performance.

Frequently Asked Questions
Got questions? We’ve got answers.
Explore some of the most common questions about AiFi, integration, and partnership opportunities.
What is AiFi mobile audio technology?
AiFi® (Artificial Intelligence Fidelity) is a patented technology by Sound Dimension that synchronizes sound between multiple mobile phones, turning them into a unified, intelligent speaker system—without any external hardware. It’s designed for immersive, social audio experiences on mobile.
How does AiFi work on mobile phones?
AiFi uses real-time AI algorithms to synchronize audio playback across multiple mobile devices. When phones running AiFi-compatible apps are grouped, they act as a single distributed speaker system—automatically adjusting timing and fidelity.
Can AiFi be integrated into third-party apps or platforms?
Yes, Sound Dimension offers AiFi technology as a licensable solution. App developers, hardware manufacturers, and streaming platforms can integrate AiFi to enhance mobile audio performance and multi-device playback experiences.
Who benefits from using AiFi mobile audio?
AiFi is ideal for:
-
Streaming platforms wanting to improve sound engagement
-
App developers creating social, music, or video apps
How accurate is AiFi’s audio synchronization between mobile phones?
AiFi uses patented artificial intelligence algorithms to analyze and adjust timing and latency across mobile devices. It ensures real-time audio synchronization without relying on external speakers, Bluetooth, or Wi-Fi pairing protocols.
What technology powers AiFi audio synchronization?
AiFi achieves sub-millisecond synchronization, using dynamic latency correction enables mobile phones to act as a coherent audio source, delivering immersive and spatial sound in real-world environments.
