Show your microphone's spectrum and a corresponding waterfall. (The screenshot shows bird chirps.)

make release

Note: If you're using Odin's library miniaudio for the first time, running make release will show an error message like

Error: Compile time panic: Could not find the compiled miniaudio library

The very same message will tell you how to compile miniaudio, something like

make -C "/home/path/to/odin/download/vendor/miniaudio/src"

After running this command, run make release again and it should work.

./mic-spectrum
