In CS2, sound isn't a simple sphere around you. Footsteps, gunshots, and landing sounds each follow their own falloff model. Understanding these three curves separately is key to converting 'I heard something' into 'where, which way, and how much time do I have'.
Introduction
In CS2, sound is often treated as a sphere centered on yourself: closer means louder, farther means quieter. This intuition isn't wrong, but at the anchoring level it's almost useless. What truly determines what you hear—and what your opponent hears—are three independent falloff curves: footsteps, gunshots, and landings. They aren't three radii of the same sphere; they are three structurally different propagation models. Distinguish them, and you can translate "I heard it" into "where is he, where is he going, and how much time do I have."
Curve 1: Footstep falloff is not linear—it's stepped
Footsteps are the most misunderstood. Many assume volume drops smoothly with distance, but the actual perception is closer to segments: close range, mid range, far range, with gentler falloff within each segment than between them. A practical result: the volume difference from 8m to 12m may be smaller than from 12m to 20m.
When anchoring, don't just ask "are there footsteps?" but "which segment are they in?" If you're holding A site and an opponent walks from connector to short boxes, you won't hear a continuous crescendo but two or three distinct steps. The pauses between steps are when they're slicing angles, walking silently, or waiting for teammates. Treat these pauses as information points—far more useful than staring at a volume bar.
More critically, footstep falloff is bidirectional. While you hear them, they hear you through the same curve. When you strafe half a step to confirm a position while anchoring, that half-step is nearly silent in your own channel but may land exactly in the mid-range segment for your opponent—the most identifiable zone. First rule of anchoring information advantage: don't let your confirmation move fall into the opponent's mid-range segment.
Curve 2: Gunshot falloff is flatter, but direction resolution is higher
Gunshots differ from footsteps. Their falloff is flatter overall, retaining a recognizable outline at long range, but direction resolution is higher—meaning you can pinpoint the azimuth more accurately, yet struggle to judge distance.
This creates a specific illusion in anchoring: you hear a gunshot's direction clearly and subconsciously assign a distance. That distance is fabricated. An opponent firing from long tube versus mid doors may differ by only tens of degrees in direction, but over ten meters in distance. If you use direction as distance, your crosshair placement will be off—and off in depth.
Pro players handle this curve by using gunshots for direction and footsteps or landings for distance. Gunshots only answer "which side," not "how far." When anchoring with only gunshot info, the safest move isn't to spray but to pull your crosshair back to the directional axis and wait for a second piece of info before deciding.
Curve 3: Landings are transients—falloff barely affects audibility
Landings are different from both. They are transient events, extremely short, with high peak volume. Their falloff curve is steep, but the steepness matters not for "inaudible at distance" but for "especially clear up close." Landing sounds are almost never masked by other sounds at close range, even while you're shooting.
This makes landings the most underrated element in anchoring information advantage. When an opponent drops from second floor to the bomb site, that landing gives you far more info than their previous footsteps: it's a timestamp. Footsteps tell you they're moving; the landing tells you the exact moment they finished moving. Treat landings as timestamps, not directions, and your counter-play rhythm will be much steadier.
Conversely, your own landing sends a timestamp to opponents. Before dropping from height, judge whether an opponent might be within your landing's audible radius. If so, the silent step before landing matters more than the counter-strafe after.
Stacking the three curves: the real algorithm of anchoring information advantage
Now put all three on one graph: footsteps give segmented positional sense, gunshots give high-resolution direction, landings give precise timestamps. Only the overlay of all three forms a complete information judgment.
The common mistake is deciding with only one curve. With only footsteps, you overestimate distance; with only gunshots, you mistake direction for distance; with only landings, you know timing but not bearing. A truly solid anchor cross-validates across all three: gunshots define the axis, footsteps define the interval, landings define the beat.
This is why at the same anchor spot, some say "I hear everything clearly" while others say "it's all noise." The difference isn't the headset—it's whether you read the three curves separately. Sound in CS2 is never a sphere; it's three overlaid maps. Whoever separates them first gains that half-second information edge.
