Mic Array For Clear Audio


I am looking for a mic array with onboard DSP, echo reduction, etc. The application is automotive: I want to replace the garbage single mic that came with my head unit with something better. The output needs to be mono audio (line, speaker or mic level). I have 12V and 5V (USB) power.

I have looked at units like the ReSpeaker or MiniDSP but they all seem to require connection to a computer (or are an embedded computer). I am looking for a simpler solution that just improves the audio output using basic DSP, echo cancellation, etc. I don’t need HDMI, voice recognition, etc. Is there anything like this out there?

Thank you
