Last week a nerdier segment of the music world was abuzz with the news that an Austrian company Rebeat had taken a $US4.8 million ($6 million) dollar investment to help bring its "HD vinyl" records to market by mid 2019. Huh? HD vinyl? How does one make the last analogue music storage format (that people still care about) high-definition?

It screamed pure marketing buzzwordship to us, but we consulted with some experts and surprise, it seems there's reason to be cautiously optimistic.
