Whoa, that was awesome!
Several decades ago, its my hobby to listen to a radio drama. It is an audio-based dramatized theater with no visual component. Its purely audio effects same as what this article shown. I just realized now that this is how complicated they did to the sound effects and its cool!
Ah yes the old radio dramas! Yes absolutely. I have been thinking of trying to get a radio drama off the ground actually. I would love to produce one.
