A subtle background ambience of muffled traffic hums through distant streets, blending a soft low‑end rumble, intermittent engine revs, and faint siren snippets caught from a moderately elevated urban viewpoint. This realistic, atmospheric layer is perfect for city‑scape soundscapes in film, documentary, podcast intros, or VR experiences where authentic street ambience needs to add depth without overpowering the primary audio track.
