Is there any off the shelf components for audio recording? Some sort of way for a user to record audio from their microphone and it either gets stored or processed in real time.
Nope, we don’t have that in store for you right now.
Feel free to make a request here.
There actually is now! I’ve made it happen 
I’ve created and published a component that offers a whole range of possibilities and customizations. The idea is for you to just drag and drop the element without wasting time For anyone else looking for a solution, I think you can find it here:
