USB 4 Mic Array


Coming soon

The ReSpeaker USB 4 Mic Array is the successor of the ReSpeaker USB 6+1 Mic Array. It has better built-in audio processing algorithms than the 6+1 Mic Array, so it has better audio recording quality, although it only has 4 microphones.


  • 4 microphones
  • 12 RGB LEDs
  • USB
  • built-in AEC, VAD, DOA, Beamforming and NS
  • 16000 sample rate


Audacity is recommended.

Install DFU and LED control driver for Windows

On Linux and macOS, the USB 4 Mic Array will just work. On Windows, audio recording and playback will also work without installing a driver. But in order to upgrade the device's firmware or to control LEDs an DSP parameters on Windows, the libusb-win32 driver is required. We use a handy tool - Zadig to install the libusb-win32 driver for both SEEED DFU and SEEED Control (the USB 4 Mic Array has 4 devices on Windows Device Manager).


Make sure that libusb-win32 is selected, not WinUSB or libusbK

Device Firmware Update

The Microphone Array supports USB DFU. We have a python script - to do that.

pip install pyusb
python --download new_firmware.bin

How to control the RGB LED ring

The USB 4 Mic Array has on-board 12 RGB LEDs and has a variety of light effects. Go to the respeaker/pixel_ring to learn how to use it. The LED control protocol is at respeaker/pixel_ring wiki.
