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

Quick Summary:

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

In a perfect anechoic chamber - one totally free from echoes - one microphone per speaker would be enough to pick up what everyone was saying; but in a real room, the problem requires a microphone for every reflected sound too.

This doesn't just mean other people who may be speaking - there's also a significant amount of interference from the way sounds are reflected around a room, with the target speaker's voice being heard both directly and indirectly.
