The use cases I’ve seen for Auracast include personal audio sharing and broadcast, aided listening in halls, churches, cinemas, public address systems, silent tvs in bars and gymnasiums, and assistive devices like this. That’s broad. I think personal audio sharing alone might be enough to drive adoption. Sharing music without needing to know your friends’ brand of earbud or phone could be a compelling use case for young people.
I’m just hoping that if they developed the standard with enough care, this won’t be necessary. It took them almost ten years, so it’s not like they didn’t have enough time.
Auracast is part of the LE Audio spec and LE Audio comes with benefits that have nothing to do with Auracast. Power efficiencies, multiple independent streams, low latency, and decent sound quality should see it part of more consumer devices over time. If LE Audio is on everyone’s mobile phone, and LE Audio is on everyone’s ear buds, business cases for Auracast become simple to make.
