The Codec is the radio system Solid Snake uses to talk with his support team in Konami's Metal Gear Solid series, first popularised by the 1998 PlayStation game. Its opening and closing tones became as recognisable as the alert sound itself, and players still quote the green Codec screen in streams and edits. The close beep spread through forums, ringtones and soundboards alongside other game alerts like enemy spotted voice lines, and it remains a shorthand for ending a secret transmission cleanly.

The Metal Gear Solid codec close beep, a short electronic confirmation tone from the game's radio screen, used for mission endings and stealth video edits.
This is the short closing tone from the Codec interface in Metal Gear Solid, a brief electronic beep that plays as the communication window shuts. It lasts just over a second and has a clean, digital radio sound with a quick falling pitch. Players instantly hear it as mission talk ending and Snake signing off. In edits it works like a period at the end of a conversation, giving a scene a tidy, secret-agent finish without needing any dialogue or extra music underneath it at all.
