USB 4 Mic Array

Note

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.

Features

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

Usage

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).

Note

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 - dfu.py to do that.

wget https://github.com/respeaker/mic_array_dfu/raw/master/dfu.py
pip install pyusb
python dfu.py --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.
