Mixlr , which we previously described as a UStream-for-audio , has exited Beta and with it a wider remit: No longer is the live audio streaming service aimed at just DJs and musicians but now targets the likes of conference organisers, journalists, podcasters and public speakers too. It's a pivot not dissimilar to that made by SoundCloud recently , a service that Mixlr both competes with and complements since Mixlr recordings can be sent to SoundCloud. But that's not all that's changed.
