Yeah my bad for not defining it. "Extra-Sensory Perception", basically as you said I believe is the most common feature -- but in general I think encompasses cheats that generally boost your "senses". So it could use audio to visually draw on your screen/radar where the sound came from.

The screenshot in this repo is kind of similar to wallhacks, but you could imagine this could easily be extended to show dropped items and the 3D audio location: https://github.com/ryanjpwatts/esp-analysis
