Meanwhile, PDM (pulse-density modulation) mics are tiny microphones with a digital output which can reduce electrical noise. You can use 8 of these (and maybe even 16!) on Bela Gem Multi to make mic arrays, useful for robotics, beam-forming, field recording and other applications.

Bela Gem Multi already supported 10 audio inputs and 10 audio outputs, 8 of which are DC-coupled. A new design change lets you use DC-coupled signals like CVs or sensor readings on 8 of the audio *inputs* as well. (Some level shifting is needed to situate these inputs between 0 and 3.3V.)

Amazing Tom - thanks!
