Facebook explained the possibilities of Live Audio like this:
“We know that sometimes publishers want to tell a story on Facebook with words and not video. We’ve even seen some Pages find creative ways to go live and reach audiences with audio only by using the Facebook Live API or by adding a still image to accompany their audio broadcast. Our new Live Audio option makes it easy to go live with audio only when that’s the broadcaster’s preferred format.”
Facebook envisages Live Audio as a new way to connect with audiences in areas with weak network connections.
