1. An image capture device, comprising:
a housing defining an audio depression;
a drainage microphone coupled to the housing at a location of the audio depression, the drainage microphone configured to capture audio;
a processor coupled with a memory storing instructions that when executed cause the processor to apply a set of tuned beamforming parameters to the captured audio; and
a drainage channel within the housing to drain moisture from the drainage microphone, the drainage channel defining a channel entrance having a channel entrance width and a channel entrance height,
wherein the channel entrance width is at least five times the channel entrance height.
