Back in April, a rumor circulated online about the possible existence of OZO Audio recording capability on the then suspected flagship smartphone from HMD Global, the Nokia 9. While the possibility of Nokia 9 to exist is extremely low for now, the rumor continues to roll over the highly anticipated Nokia 8. If this is real, it will be one of the main selling point of the device.

But what is OZO Audio?

The video you see above is a demonstration of how OZO Audio performs in real life. As the video suggest, these were taken with two mobile devices (which could possibly be the Nokia 8). The difference is highly noticeable. Make sure to use headphones.

OZO Audio is a group of enhancement engines that is capable of capturing spatial audio. It was first used on OZO, Nokia’s VR camera. When building the OZO VR camera, Nokia decided to incorporate spatial audio recording with the images captured by their VR camera to give users a sense of immersion to the content. OZO Audio remembers from which corner the sound was captured, giving you a more immersive experience rather than just rely on the images. This makes the sounds more natural as if you are hearing it in real life. The similar technology already existed on Nokia’s previous handsets, particularly on the Lumia line-up, in the name of Rich Recording. However, what makes the OZO Audio more advanced than the Rich Recording is that it is capable of capturing full 3D audio.

The story of OZO Audio has been brought up again after one of HMD Global’s high ranking official teased via Twitter about the “mind blowing OZO Audio” from an unannounced device. The post reveals Kuala Lumpur International Airport as the location of testing which is an ideal testing ground for OZO Audio. 

While Nokia and HMD aren’t connected with each other in terms of mobile devices, Nokia Technologies has brand partners that work closely with HMD Global to make sure that the product are in line with Nokia’s high standards.
