H3 Sentinel Beam Long Burst Cooldown Sound Effect

A long, descending electronic hum that fades out, capturing the cooldown of the Sentinel Beam after an extended burst. The sound has a metallic, sci-fi texture with a slight resonance, typical of Halo 3's weapon audio. It's well-suited for game development, fan films, or sound design projects needing a post-firing weapon recharge sequence. The effect lasts several seconds and provides a clear, distinct audio cue.
