Place this clip right after the Bomb Has Been Planted announcement, so the clip confirms the plant in the edit, then cut to Enemy Spotted as defenders rush the site. Keep it as the turning point between the setup and the rush, with the plant call first and the reaction second.
About this sound
This is a single sharp electronic beep from the planted bomb in Counter-Strike, lasting less than a quarter of a second. It cuts through the noise with a clean, high-pitched tone that feels urgent and tense, like a warning that something is about to happen. In the game, it marks the bomb and raises the pressure on every player nearby.
