we make sound
and silence
Our team specialises in the development of algorithms for noise reduction and sound design. We use our algorithms to create user-friendly software, tailored to your needs.
Automotive Active Noise Cancellation & Sound Design
SPB AUDIO LAB
Official partner algorithm for Hyundai Mobis & Hyundai KIA
For more than five years, we’ve worked with leading global OEM and Tier-1 partners to develop and integrate advanced noise-cancellation technologies into real-world vehicle systems
5+ years
Four serial-production vehicle models are equipped with our noise suppression algorithms, with new models being prepared for deployment
4+ car models
One platform - Three acoustic capabilities
Control unwanted noise, create a distinctive powertrain sound and deliver audio events to the right listener
CANCEL

Not another acoustic demo
SPB technologies are designed around the realities of vehicle programs: changing cabin conditions, limited compute resources, shared audio paths and the need for fast, repeatable tuning
Real vehicle experience
Engineering decisions informed by real integration and production-program constraints
Integration-aware architecture
Clear inputs, outputs, deployment boundaries and resource-aware configurations
Repeatable tuning workflow
Tools and methods for calibration, validation, debugging and quality control
Flexible deployment
Audio Weaver deployment pathway, standalone library or reference implementation options
Built to fit the vehicle platform
Our algorithms can run either directly on the target hardware or within the DSP Concepts Audio Weaver (AWE) environment. Both deployment paths are supported by a repeatable tuning and validation workflow.
- Defined inputs and outputs
- Resource-adaptive configurations
- Shared audio-path coexistence
- Diagnostics and OTA-ready architecture
Acoustic technologies for real vehicle programs
Modular technologies that can be evaluated independently or combined on a shared platform when system resources allow
