I'm interested in using the AudioMoth-Live command line tool on a Raspberry Pi 4 to capture multichannel recordings from a Zylia ZM-1 microphone array. This array has 19 channels with a built-in 24-bit ADC to transmit over USB. Is it possible to capture multichannel and/or 24-bit audio using AudioMoth-Live? If it's not designed for this, are there any potential work-arounds? I've successfully captured recordings from the array but they're a single channel in 16-bit, and I'm not sure if the issue is with the command line tool or how the device drivers / sound cards are being handled by the Pi. Any help is appreciated, thanks so much!

Hi Charles, It's probably easiest to do this directly from a Python script. This application note -
- has an example Python script for recording from the AudioMoth USB Microphone, and also an example of using arecord in Linux. It would probably be relatively straightforward to modify these for your microphone.
