AudioShake — a startup that uses AI to deconstruct music tracks into stems that can be used for remixes, sampling and other applications — has announced it’s just raised USD $2.7 million in a seed round. That takes its total fund-raising to date over $5 million, the company said. Among the investors in the round are Black Squirrel Partners, a growth equity and content investing firm founded by Metallica, alongside Q Prime, Eric Wasserman, Paul Donahue and others.
