Better audio makes better smartphone video possible

With Nokia's rich legacy in device technology, we know that high quality audio is critical to unlocking the video experience. OZO technology enhances the overall content experience and sets any smartphone apart from its competition with next-level audio performance.

Great audio made better together

The OZO portfolio enables unparalleled audio fidelity for smart devices from capture through editing to playback. OZO Audio and OZO Playback are designed to work as standalone products. Either can be integrated into a device independently, but when installed together, they enable even better performance capabilities.

Introduce new ways to capture and edit audio

The combination of accurate spatial audio analysis with smart multi-microphone, audio-processing algorithms enables an entirely new set of spatial audio features. These features give users and device makers unprecedented flexibility to focus, zoom, edit and even suppress wind noise without hardware modifications. Intelligent processing is at the core of OZO Audio.

Deep analysis of sounds

Advanced analysis of the multiple microphone signals forms the basis of the OZO Audio algorithms. OZO Audio can both capture high-quality spatial audio and provide focus, zoom and wind noise reduction capabilities.

Universal playback and sharing

We designed OZO Audio to work everywhere. With universal playback and sharing, users can share true-to-life, immersive content, regardless of what spatial audio software runs on their audiences’ devices. OZO Audio technology can be shared across any social media platform and heard through any device – laptop, tablet or smartphone.

Capture now. Tune later

Using smart, multi-microphone, audio capture algorithms, Audio Tune enables unique capabilities for exploring and editing post-capture. Whether user-enabled or AI enabled, all the OZO Audio features can be controlled for optimal desired output, giving users endless freedom to fine-tune content.

Transform any stereo speaker device for unprecedented loudness and spatial quality

OZO Playback provides an enriched listening experience for smartphones with stereo loudspeakers creating a sonic experience that is louder, broader and incredibly rich.

Optimized for stereo

OZO Playback is optimized for devices with stereo speakers. The ultimate sonic experience can be achieved with symmetrically placed loudspeakers, but what sets OZO Playback apart is its ability to accommodate asymmetric speaker configurations just as effectively.

Nokia audio engineers design and precisely tune smart algorithms for processing the spatial sound to that device. The result: a superbly enhanced audio experience, where users perceive sound from “virtual speakers” on either side of the device. While the best experience can be achieved through symmetrically placed loudspeakers, our algorithm can be tuned to provide an impressive stereo-widening experience for asymmetric loudspeaker configurations as well.


Implementation tailored to your device

The design of an advanced audio capture and playback system requires a coordinated implementation combining the design of product acoustics and spatial audio algorithms. To achieve the highest-quality audio output, we partner closely with manufacturers with a customized integration tailored to their device specifications.

Process implementation

To maximize the performance of the audio capture and playback technology, we utilize an array of design methods that enable us to take audio measurements and model the product acoustics.

Our workflow enables early evaluation of the target performance and efficient comparison of alternative designs, bypassing the need to wait for performance evaluations until mature target product hardware becomes available.

Microphone configuration analysis

With over 20 years of experience in mobile phone design, partnering with the Nokia engineering team has distinct advantages. The key to optimal performance and quality is in the careful design and tuning of the mic and speaker algorithms to an individual device.

For the Nokia OZO Audio portfolio, the basis of all our algorithms is the analysis of the multiple microphone signals. OZO Audio requires a minimum two microphone configuration, but three or more mics enable advanced feature capabilities. More microphones also translate to better audio fidelity allowing us to enable high-quality spatial reproduction, and means we can provide advanced capabilities for audio capture and editing.

Product design support

Effective product implementation requires careful consideration of the number of microphones and speakers and their placement. Relying on a deep expertise in audio engineering, we partner with you to solve challenges of spatial audio capture and playback, and design for optimal device performance in all conditions and use cases.
