Is there a app for precise triangulation of sounds?

How? Sound in warfare is used for echolocation, thats opposite of sound location.

i think i recall seeing some fancy I2C microphone array parts that advertised source locating as part of their built in firmware. 8 microphones in a ring on a board. Sony, iirc.
