Advanced Audio Signal Processing
Clean audio is the foundation of reliable acoustic sensing — whether the downstream task is voice control, event detection or condition monitoring. We solve the challenges of ambient noise, reverberation and source localization with proven signal processing methods and custom algorithms, optimized for our Embidio platform and other embedded targets. From beamforming to echo cancellation, we deliver production-ready audio pipelines.
Key Benefits
Beamforming
Focuses audio capture on the speaker using algorithms like delay-and-sum and adaptive techniques for maximum clarity.
Noise Reduction
Far End Noise Reduction
Acoustic Echo Cancellation (AEC)
Robust feedback suppression ensures precise command recognition even during simultaneous audio playback.
Comfort Noise Generator
Direct Current (DC) Filter
Leveler
Automatic Gain Control (AGC)
Acoustic Echo Suppression (AES)
Equalizer (EQ)
Our Process
Audio Environment Analysis
We assess your acoustic environment, noise sources, and microphone setup to understand the signal processing requirements for your product.
Algorithm Selection & Design
Based on the analysis, we select and configure the optimal combination of algorithms — beamforming, noise reduction, echo cancellation, and more.
Implementation & Tuning
We implement the audio pipeline on your target platform (Embidio, XMOS, ARM, or custom hardware) and fine-tune parameters for your specific use case.
Simulation & Real-World Testing
Rigorous testing in simulated and real acoustic environments to validate performance under all expected conditions.
Production Deployment
Final optimization for latency and resource usage, documentation, and integration support for production rollout.
