Technology Engineering & Integration
We help hearing technology companies evaluate, integrate and optimise established audio DSP and wireless audio platforms — accelerating prototypes and improving speech intelligibility in noise.
Compare candidate platforms against your positioning, power budget and algorithm needs, and define the integration route.
Development and tuning support for gain and compression, feedback management and noise reduction.
Assess benefit, latency and compute requirements of AI speech enhancement in your target scenes.
Design and evaluation of microphone layout, beamforming and directional processing.
Optimisation guided by objective metrics and listening tests.
Latency budgets and embedded implementation for real-time hearing devices.
Development support for LE Audio and broadcast audio (Auracast) assistive listening.
Performance and suitability evaluation of vendor reference designs.
Testing, diagnosis and improvement recommendations at prototype stage.
Established Technology Platforms
基于成熟技术平台，加速产品创新与性能提升。
Developing a complete hardware architecture from scratch is slow and risky. We evaluate commercially available semiconductor and DSP platforms for OEM engineering and product development, and concentrate time and budget on what differentiates your product: algorithms, tuning, validation and user experience.
onsemi's programmable DSP family for hearing aids and hearing devices.
Platform direction under evaluation
NXP offers embedded audio processors and low-power wireless microcontrollers, some supporting Bluetooth LE Audio.
Platform direction under evaluation
Prototype and evaluate algorithms offline on PC or general embedded development platforms before porting to target silicon.
Our default starting point
Discussed only where commercially or technically relevant and verifiable. We do not claim its historical algorithms are available for licensing.
To be verified
Choose your product type to see which platform direction to evaluate first, and the key questions to answer.
Evaluate firstonsemi Ezairo
Why: Hearing aids are extremely constrained in power, size and latency, so a dedicated hearing-aid DSP is usually the most direct starting point.
Key questions
Evaluate firstNXP
Why: Wireless audio is central here, so low-power wireless platforms with LE Audio capability are a better fit.
Key questions
Evaluate firstNXP
Why: Broadcast audio such as Auracast needs an LE Audio-capable wireless platform; capabilities must be confirmed per device.
Key questions
Evaluate firstHardware-independent software
Why: Validating benefit, latency and compute in a hardware-independent setting before choosing silicon reduces selection risk.

Tell us your product positioning, power target and algorithm requirements, and we will map out platform options and an integration route.
Longer-term R&D direction
Intelligent speech enhancement for communication in challenging acoustic environments.
R&D direction — not a commercial productMixed sound from one or more microphones
Front-end processing, spatial filtering and feature extraction
Keep the target talker, suppress noise and interferers
Hearing aid, earbud or assistive listening device
We start with an audio-only, hardware-independent strategy so the work can move across chip platforms and product forms. Audio-visual enhancement is a longer-term research direction.
We intend to combine commercial engineering projects with independently developed, reusable technologies. IP ownership is agreed in each contract in advance, and client technology and data are never used for other clients.
These are research and development directions, not completed commercial products. We do not claim measured performance improvements, patents, published results or finished prototypes.
