6 Core Features Designed for Acoustic Excellence
Lossless Raw Audio Output
Pure Hardware Capture: Operates without soft-algorithm filtering, gain modifications, or noise suppression baked in.
Complete Data Integrity: Preserves all raw audio features—including natural voice, spatial reverberation, and background noise—to satisfy strict academic and R&D requirements.
8-Channel Synchronous Zero Phase Difference
High-Precision Linear Layout: Equidistant silicon microphones ensure precise spatial sound field mapping.
No Delay or Phase Drift: Facilitates fine-tuned beam steering, Sound Source Localization (SSL), and Time Difference of Arrival (TDOA) algorithm testing.
10-Meter Far-Field High-Definition Pickup
Optimized Acoustic Architecture: Enhanced hardware gain enables full-range audio capture up to 10 meters away.
Distortion-Free Recording: Reliably picks up low-amplitude human voices and faint distant acoustic events without frequency clipping or signal interruption.
USB Plug-and-Play & High Compatibility
Universal Interface: Works standard USB audio class protocols across Windows, Linux, Android, and embedded platforms.
Quick System Integration: Requires zero dedicated software drivers, dramatically shortening product development cycles for conference terminals and AI robotics.
Industrial-Grade Anti-Interference & High Stability
Shielded Circuit Architecture: Built with industrial-grade audio acquisition ICs and electromagnetic shielding to prevent current noise and crosstalk.
24/7 Continuous Operation: Guarantees zero data loss, zero signal drift, and minimal thermal noise during prolonged recording sessions.
Hardware Support for AEC Channels
Designed with hardware considerations to support Acoustic Echo Cancellation (AEC) workflows, allowing seamless reference signal integration for double-talk algorithm training.
