greetings! has there been an attempt to stream the audio / bytes data over USB back to a host machine? This would be instead of writing to the SD. I understand if the paperclip is in, the device shows up as a tty serial device. Can we read the serial out from this by modifying the firmware?

We're trying out a few ideas to implement this. One option that looks feasible is to implement a USB microphone protocol so that you can record at any sample rate up to 384kHz using exactly the same gain and filters that the normal AudioMoth front-end uses.
