Acoustic Technology Insights

The Raspberry Pi has long been the favorite brain for DIY AI assistants. However, getting high-quality audio input into a Pi Zero or Pi 4 has historically required bulky USB

Privacy and latency are the two biggest hurdles in modern voice UI. Sending raw audio data to the cloud is no longer the only—or best—option. The SISTC X316-LDP Development Board

In the rapidly evolving landscape of AI-driven interaction, the clarity of voice capture in “real-world” noisy environments is the ultimate bottleneck. Whether it’s an interactive kiosk in a busy airport

As voice interaction becomes the primary interface for smart devices, traditional dual-microphone systems are no longer sufficient. To achieve: modern systems are rapidly shifting toward multi-microphone arrays (4, 6, or

In Part 1, we introduced the fundamentals of microphone arrays and beamforming.Now, we move into the engineering core—how a 2-microphone (dual-mic) array actually works, and why it remains the foundation

As voice interaction becomes the primary interface for AI-powered devices, microphone array technology has become a critical enabler for accurate and reliable audio capture. From smart home devices to automotive

Introduction In our previous post, we covered the foundational physics of two-element microphone arrays. However, to achieve true professional-grade audio in challenging environments—such as voice-controlled kiosks or smart conference systems—we

Introduction In the evolving landscape of Edge AI and smart acoustics, a single microphone often falls short in noisy environments. At Wuxi Silicon Source Technology (SISTC), we’ve spent 15 years
