Once you’ve installed the DAW Plugin and signed in, hit the ‘Start live broadcast’ button to start your broadcast. You will see a three second countdown then will be live in the Blast Radio mobile app. Make sure to do a Sound Check before broadcasting to ensure you sound good.
Note: You can always download a lossless wav file of your broadcast and reuse it however you like. See this article on how you can download your broadcasts after they are finished.
