      Description

      ReSpeaker 4-Mic Array for Raspberry Pi is a quad-microphone expansion board for Raspberry Pi designed for AI and voice applications. This means that you can build a more powerful and flexible voice product that integrates Amazon Alexa Voice Service, Google Assistant, and so on.


      Different from ReSpeaker 2-Mics Pi HAT, this board is developed based on AC108, a highly integrated quad-channel ADC with I2S/TDM output transition for high definition voice capture. Besides, this 4-Mics version provides a super cool LED ring, which contains 12 APA102 programmable LEDs. With that 4 microphones and the LED ring, Raspberry Pi would have ability to do VAD(Voice Activity Detection), estimate DOA(Direction of Arrival) and show the direction via LED ring, just like Amazon Echo or Google Home.


      Note

      • Please note that the package does not contain Raspberry Pi.

      • Please note that there are no any audio output interfaces on ReSpeaker 4-Mic Array for Raspberry Pi. It is only for voice capture. And you could use the headphone jack on Raspberry Pi for audio output.

      That's really cool! It could potentially answer some of our need to have good mic in our conference room (and some project related to "limitation of the time to speak" and location of a speaker).Have you developed all the necessary drivers?Do you ship to Switzerland?

      Is this a "connect to the cloud to work" device, or is it stand alone? Would it work with Mycroft?
      on Sep 20,2017

      It's a 4-mic array for Raspberry Pi, like sound card, but just for voice capture. As I know, MyCroft is based on Raspberry Pi, I think it can work with MyCroft.

      I would like to buy one but the shipping charges are too much for me, will it be available from a reseller in the United States?

      Hey Dave. Sorry to hear this. We are speaking with our partners now. I would guess that you can find one by the end of October, but definitely within 2 months.

      Hi, so do I have to use those SPI headers? Or I can just bypass the led control, cause I need them for something else that's more important

      So does this play back at chipmunk speed like the 2 Mic Pi HAT version?

      Play back audio in Raspberry Pi, so it dependent on RPi.

      What is the sample rate for this?
      on Sep 02,2017

      The driver supports 8kHz,16kHz, 48kHz now. But it will cover all sample rate later, include: 8kHz,12kHz,16kHz, 22.05kHz, 24kHz, 32kHz, 44.1kHz, 48kHz, 96kHz.
