ReSpeaker XVF3800 USB Mic Array - AI-Powered 4-Microphone Array

The ReSpeaker XVF3800 USB Mic Array is a professional 4-microphone array powered by the XMOS XVF3800 voice processor. Advanced audio processing technologies including Acoustic Echo Cancellation (AEC), Automatic Gain Control (AGC), beamforming, Direction of Arrival (DoA), Voice Activity Detection (VAD), dereverberation and noise suppression provide clear voice capture even in challenging acoustic environments.

Supporting both USB and I2S operating modes, the module integrates easily with PCs, Raspberry Pi systems, embedded platforms and AI voice applications. The circular microphone arrangement enables reliable 360° far-field voice pickup up to 5m. Additional ReSpeaker family variants are available with pre-installed XIAO ESP32S3 modules and with or without enclosure options.
