Chinese Overview:
Wuxi Silicon Source Technology is proud to introduce our state-of-the-art Array Microphone Module designed for superior voice capture and noise suppression in challenging environments. Leveraging the power of dual microphone directional pickup and deep learning noise reduction algorithms, this module ensures clear voice extraction in real-time, even in high-noise scenarios, achieving up to 30dB of noise suppression.
Key Features:
1. Advanced Noise Reduction Technology:
Our Array Microphone Module employs cutting-edge deep learning noise reduction and beamforming technology, allowing for the real-time separation of target voice from background noise. With an industry-leading 30dB noise suppression, users can enjoy exceptional speech interaction in AI-powered applications, even in noisy environments.
2. High-Precision Far-Field Pickup (3–5 meters):
Ideal for home and office environments, this module supports far-field pickup from 3 to 5 meters. With high-precision voice identification and fast response times, this module can capture clear audio from a distance, making it perfect for AI products, video calls, and other communication systems.
3. Real-Time Voice Isolation:
By effectively separating human voice from background noise, the Array Microphone Module delivers clear, smooth audio for video calls and speech recognition applications, even in high-noise environments.
4. Seamless Integration & Developer Flexibility:
The sy6228C USB interface outputs 4 independent digital channels of audio in PCM format. This module also provides adjustable settings for noise reduction and microphone gain, giving developers flexibility for custom signal processing algorithms. It is compatible with Android, Windows, and Linux platforms, offering complete control over signal azimuth estimation, noise reduction, and enhancement.
5. Industry-Leading DSP Processor:
At the heart of the Array Microphone Module is a high-performance DSP audio processor that runs on an ultra-low-power 32-bit RISC core. The processor offers 320 MHz maximum frequency and supports floating-point algorithms, making it ideal for high-performance audio applications. This processor ensures top-quality sound processing and superior real-time signal handling for all your voice and audio needs.
DSP Processor Features:
- 4-Channel Digital Microphone Input: Captures audio from multiple sources simultaneously.
- High SNR: Signal-to-Noise Ratio (SNR) of ≥105dB ensures pristine audio quality.
- Wide Sample Rate Support: Supports a variety of sample rates including 16kHz, 22.025kHz, 44.1kHz, and 48kHz to cater to different audio needs.
- Headphone Support: Directly drives 16Ω or 32Ω headphones, delivering excellent audio output.
- Multiple Audio Interfaces: Includes an S/PDIF interface, HDMI audio, and ARC support for versatile audio input/output options.
- USB Power & Communication: Operates on USB 5V power supply and supports USB 2.0 Full-speed OTG with up to 6 endpoints for efficient data communication.
