Direct-to-reverberant ratio Anyone who has used a digital reverberation unit knows that the way to make things sound farther away in the mix is to increase the level of the reverb relative to the dry sound. This is essentially creating the same effect we have in real life. We've seen earlier that, as you get farther and farther away from a sound source in a room, the direct sound gets quieter and quieter, but the energy from the room's reflections - the reverberation - stays the same. Therefore the direct-to-reverberant level ratio gets smaller and smaller. MAKE SURE THAT ROOM RADIUS IS COVERED IN ROOM ACOUSTICS CHAPTER
