USB 4 Mic Array
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
- 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 - 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
