A detailed spectrogram-style chart visualizes the noises produced during a dial-up modem handshake, dividing the connection into network initiation, cryptographic negotiation, and password transmission. The joke is that an everyday nostalgic sound is presented with extremely technical scientific seriousness, making it useful as a reaction to something complicated, overly elaborate, or needlessly analyzed.
