ReSpeaker Mic Array V2.0 audio output

Hello,



I just have some questions about the concerning the ReSpeaker Mic Array V2.0.


  1. Can the ReSpeaker Mic Array V2.0 output realtime AEC filtered audio from its 3.5mm audio jack? In my application, I’m hoping to use the ReSpeaker as a microphone for an intercom system in a noisey environment. I need the filtered audio to be output to a transceiver for a private voice radio system. Once programmed, this possible without external hardware?


  2. Is it possible to add a delay to the audio output without external hardware? If, in my application, I need to add a delay of up to 1 second to the recorded audio, is the ReSpeaker Mic Array V2.0 capable of this? Does it have built in memory?



    Thank you!

Hi,


  1. Yes it supports Full-duplex AEC with barge-in support (up to 50dB att.)
  2. You can programme using C, C++ or xC (C with multicore extensions). XMOS provides tested and proven software libraries.
