ReSpeaker 4 Mic Array firmware

Hi,
we are using the respeaker v2.0 4 mic array for an audio tracking project and were wondering if there is a way to disable the voice processing entirely so as not to filter out other noise. Do any of the firmware binaries work well for this, or are there other parameters that can be set to ‘off’ to accomplish this?

Hi 

Yes, you can use the 6 channels firmware and select the channel 1~4, they are the raw audio from 4 mics. there are some 6 channels firmware and you can select the best one fits your project.
