AI's solution to the 'cocktail party problem' used in court

The technology has been used to filter out background voices in audio evidence in a US murder case.

Electrical engineer Keith McElveen, founder and chief technology officer of Wave Sciences, became interested in the problem when he was working for the US government on a war crimes case.
