Presence Footsteps is an overly complicated footstep sound enhancement mod for Minecraft. It changes the way footstep sounds are produced, in addition to a whole new set of sounds.
This only enhances your footsteps, not those of other players.
It adds new sound effects such as jumping, landing, walking on the edge of a block. These effects don't play on Minecraft alone, it couldn't be achieved with just a resource pack.
It plays sounds differently whenever you're running, and allows each block to be played in a different way: Metal fences do not sound like iron blocks; Walking over rails both plays a faint metallic sound and the surface below it; Walking on a piston pointing upwards sounds like wood.
Presence Footsteps is compatible with Forge and LiteLoader.
