Limes Audio is a company that develops technology that improves audio quality in communication. Obviously that’s something that Google will value, so Google has purchased the company.
With many businesses using Google’s video chat system and a few people still using Hangouts, improving audio quality is very important. Things like poor connection, echoes, and ambient noise are all factors that worsen audio and Google aims to improve them with the help of the Limes Audio team. Hopefully we’ll see significant improvements soon!
