Not pushing the product or anything, but came across this. I don't see any audio options other than the mic on the front which im dubious about. Im hoping they have something like the app in standalone for the iphone to create some better shots etc.
I've been using the setup shown using facebook live in the recent DJTT article and its been a lot of fun. If i create an events page, people can log in amd watch it happening and share it out quite rapidly.
Need a bigger tripod or something to get better angles of the crowds though.
