They Say

Just connect an antenna to your computer's microphone input, and you can receive VLF (Very Low Frequency) radio signals! A sound card (or built-in sound chip) with a recording sampling rate of at least 96 kHz is recommended.

Example of using this method to receive VLF signals from Russia and Europe:
