Raw audio is just the start. To make your microphone system truly AI-ready, it needs real-time signal processing that enhances clarity, removes noise, and prepares your voice data for accurate recognition and low-latency performance.
We develop embedded firmware and digital signal processing (DSP) stacks that run directly on your hardware or companion processors—transforming mic input into clean, optimized voice data your models can trust.
What We Offer
- Voice Activity Detection (VAD): Filters out silence and only processes true voice events to reduce computation and bandwidth.
- Echo Cancellation: Removes feedback from speakers and other devices for clear duplex communication.
- Noise Suppression: Minimizes environmental noise such as fans, street sounds, or machinery—essential in industrial and medical environments.
- Automatic Gain Control (AGC): Normalizes volume for consistent audio input, even with soft or distant speakers.
- Equalization (EQ): Tuning to emphasize vocal frequencies and improve clarity for downstream AI models.
These processing tools work together to dramatically improve transcription quality, wake-word detection, and overall speech understanding—especially in noisy or dynamic environments.
Where It Runs
- On-mic DSP chips: For low-latency, edge-based audio processing
- Microcontrollers (MCUs): Integration into STM32, ESP32, and similar platforms
- Host SoC or SBCs: DSP libraries deployed to Linux-based systems like Raspberry Pi or Jetson
We support both fixed-function audio processors and embedded firmware stacks that can be tuned post-deployment. If you’re not sure where processing should live, we’ll help you choose the most efficient architecture.
Tailored to Your AI Stack
Our firmware is designed to complement your voice application—whether you’re using cloud transcription, on-device models, or hybrid workflows. We work closely with your software or AI team to ensure every decibel of audio is maximized for intent detection, transcription, and classification accuracy.
Deliverables Include
- Compiled firmware binary and full build toolchain
- Real-time tuning parameters for AEC, AGC, EQ, and VAD
- Latency and audio quality test results
- Integration guide and API reference (if applicable)
- Ongoing support for tuning and firmware updates
From Mic Input to AI Insights—Smarter, Faster
Signal processing is what turns raw sound into usable, actionable input. Whether you’re building a voice assistant, a medical interface, or a smart kiosk, our DSP solutions make your hardware ready for real-world speech interaction.
