This is a very simple command line utility written in Rust for measuring the gain of a microphone. It displays the values in dBFS. This is useful for knowing when a microphone's gain is set to an appropriate level to avoid clipping.

Currently defaults to using the default microphone. Future plans seen in the todos.
