An innovative SDK realizes the world’s best MPEG-H standard-adopted spatial audio with low computational amount
GSA (GAUDIO Spatial Audio)
Gaudio Lab’s spatial audio solution is not only lightning-fast in response time but also captures the subtle characteristics of the original sound.
High-quality, out of the box spatial audio solution.
A world-class, high-quality spatial audio with low latency of less than 0.05 seconds.
Key Features
Deliver immersive sound for any occasion
Gaudio Lab's own technologies realize spatial audio even in an environment with no head-tracking.
Apply spatial audio to the live streaming experience without changing your existing workflow
GSA Head-Tracked
Spatial audio of incredible quality realizedwith surprisingly low computation.
GSA can also be implemented directly on the digital signal processor (DSP) chip in TWS with its low computation.
Spatial audio of world-standard quality available on smartphone, TWS and many more, without much difficulty.
-
Exceptionally low latency of only 50ms Implement the world's best spatial audio without latency issues.
Typical spatial audio processing demands significant computing resources and is hard to achieve without the help of a host device, such as a smartphone. This causes latency between the smartphone and TWS, which disrupts the user's immersion. GSA runs on TWS’s DSP chip, providing an immersive sound experience without the latency caused by device communication.

Everything is ready Sound tuning made easy with the Tunemeister app
GSA is all set to be implemented on your device. With the Tunemeister app, sound tuning becomes much easier. Design your ultimate sound experience with the sound experts at Gaudio Lab.
GSA Fixed
Vivid sound delivered without head trackingGSA Fixed analyzes signals and reconstructs sound in a three-dimensional space, delivering immersive sound that makes you feel like you're in the room, even without head movement. Experience the high-quality sound delivered by Gaudio Labs' binaural rendering technology, which is recognized as an international standard for both quality and performance.
GSA for Live Streaming
Spatial audio production made easyApply spatial audio to the live streaming experience without changing your existing workflow
-
Fully Software-based Provides a software-based solution for spatial audio production.
This software-based solution with an intuitive UI makes it easy for even the most casual users to set up spatial audio streaming without any difficulty. This solution works seamlessly with a variety of video switchers and live streaming software (VMix, OBS Studio), even in live production environments with multiple cameras.
-
Being There Spatial audio that changes according to scenes offers realistic sound experience even in a 2D environment.
The AVVA(Automatic View-Adaptive Audio) technology provides spatial sound that changes according to video scenes, letting the viewer have an experience of “being there” in an on-screen 2D environment. AVVA on BTRS is connected to video switcher and live video streaming software, automatically processing spatial audio according to the scene.

FAQ
Frequently Asked Questions about Gaudio Lab’s Solutions
Is it possible to experience GSA with speakers?
GSA, and spatial audio in general, is essentially a technology for earphones/headphones.
Sounds rendered using GSA can also be played through stereo speakers, with no loss of sound quality.
What is Motion-to-sound latency?
Motion-to-sound latency is the time it takes for a sound to render and play in response to a user's movement.
If this latency is too long, it can cause a mismatch between the auditory experience and other stimuli, including visuals, which can lead to a loss of immersion and even motion sickness.
What is externalization?
When you wear earphones/headphones, it's common for sound images to be formed inside your head.
However, sounds in real life mostly come outside of your head, so it doesn't feel natural to have a sound image formed inside your head.
In this case, psychoacoustically simulating the way humans actually hear sound can make it feel like the sound is coming from the outside, even if you are wearing earphones/headphones.
What kind of audio formats does GSA support?
GSA is compatible with common 2-channel stereo sound sources as well as the 5.1-channel surround format popular in movies.
How is GSA Head-Tracked and Fixed different?
Spatial audio is a technology that aims to create the illusion of sound coming from the real world, even when you're wearing headphones as if you're not.
Head-tracked spatial audio technology uses IMU sensors to reflect these movements. In this case, you can get the feeling that the sound is coming from outside (externalization), which makes it feel more like the image and sound are matched.
However, if it is not appropriate to apply an IMU sensor due to the nature of the content being viewed or the limitations of the device, spatial audio is implemented by fixing the position of the screen and head. In this case, even if you move your head, the sound does not move with you, creating a gap between the actual screen and the sound.
