Place it after the on-screen mistake and before your reaction shot, then follow it with the classic error sound for a second tech-failure beat. In simulator edits, lead in with a bell ding before it to mark the system notice.
About this sound
This clip is a short electronic warning tone built from sharp, repeating alert beeps. It creates a feeling of tension and urgency, like a problem has just been flagged and needs checking right away. It recreates the master caution aural warning used in Boeing aircraft cockpits to alert the flight crew.
