The mic array must work with ReSpeaker Core or can it work individually as a microphone?

Does that mean I could connect it via the usb interface to an raspberry pi directly, for example? I guess the necessary drivers are not (yet) released? Will there be drivers for the mic array alone?

How can I use ReSpeaker Mic Array on Windows 7 x64. When installing drivers, it says: "ERROR CODE (52)". I downloaded the driver from the github by reference.

Hello, I am sorry for the inconvenience you have had. Did you try a another windows PC?

Thanks.

Yes, we tried installing drivers on 3 Windows 7x64 machines but were getting the same error (52). When we launch it the system is able to detect the device and the LEDs react to voice. After removing the digital signature from the drivers the error changed to"10". Please advise as we need to get this working as soon as possible

Also it's missing the audio output for headphones. Please help. Thank you.

According to github page the firmware version 0x82 (raw) supports upto 32KHz 8 channel audio recording. I tried the 8 channel recording using Audacity (WASAPI) but the maximum sampling rate I could get was 8 KHz which was lower than that supported by earlier firmware. Further the node-HID tool does not seem to work with the new firmware.What can be done in this regard? How do I get higher sampling rate.

You can use pyaudio to 8 channel audio. On windows, you need the special pyaudio from http://www.lfd.uci.edu/~gohlke/pythonlibs/#pyaudio

Thanks for the prompt reply, I was using this: https://stackoverflow.com/questions/26391055/multichannel-pyaudio-with-asio-support with pyaudio as you said but I am still getting only frequencies upto 4 KHz i.e. sampling rate of 8KHz. What can be done?

Hi,
We have not tested mic array on Android phone. You could test it by yourself. One USB OTG cable is enough.

Update. Microphones are working on Windows 10. I have plugged them on Android using the OTG cable. I can hear the sound through the plug but the microphones do not transmit the sound. Is there any solution to this issue? Please advisehttps://ibb.co/jeAjtQ

Will the mic output the raw sound source position? What other comms are available to the board - I2C, SPI etc?

if you look at wiki https://github.com/respeaker/get_started_with_respeaker/wiki/Mic-Array at the protocol excel file, it has a voice angle 0-350 value. I assume I2C or Serial will be present (in addition to usb)

Can the options of the XVSM-2000 (Beam forming, de-reverb, AGC, Echo cancellation etc) be controlled within the ReSpeaker Core Openwrt? If so, i am assuming a driver for the USB connection between the ReSpeaker Mic Array and Respeaker Core. Could you please let us know how to interface with this driver?
