ReSpeaker MicArray v2 & Mac

Post by franz.harmer » Wed Jun 12, 2019 12:20 am

Hi,

I'd like to use my new MicArray v2 as a general usb mic device on mac, preprocessed for voice input.

Currently the factory firmware is installed. I see all 6 channels and input works, but the Audio MIDI Setup app cannot control specific channels on the device for me to prioritize channel 0 (processed for voice).

Alternatively I could change the firmware the 1-channel version but the forum recommends not to do this from a Mac - I'm not sure if this means not to update the firmware from a terminal window, which would be my approach.

Is there a way for me to select the correct channel on mac, or change the firmware?

Thanks

Hi there,

Yes, you can update the firmware to 1 channel firmware and you will get the processed audio.

You can update the firmware on Mac. there is no issue. You can follow below instructions. thanks.

Incidentally, for other people viewing this thread, pyusb relies on libusb to be installed on your mac to do the low-level dfu communications with your usb devices. See here https://stackoverflow.com/questions/385 ... n-mac-os-x on how to do that.
