In fact, human beings are remarkably adept at holding a conversation with one person while filtering out competing voices.

However, perhaps surprisingly, it's a skill that technology has until recently been unable to replicate.

And that matters when it comes to using audio evidence in court cases. Voices in the background can make it hard to be certain who's speaking and what's being said, potentially making recordings useless.

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.
