Capturing reverb acoustically through room tracks

It's important to understand the tools and technologies we use for creating reverb. There are many of them so we break them down into three families, acoustic, mechanical, and digital. As the very idea of reverberation is born from room acoustics, we'll start there. Allow me to hit you with a bit of math. Here is Sabine's Equation for Reverb Time, which applies to all large sonically diffuse spaces. This equation quantifies how long it takes the room to decay to silence, or more specifically, how long it takes the level to fall by 60 dB, a significant reduction in amplitude and a decent proxy for silence.

Let's listen to a snare drum with 3 seconds of decay. (music playing) The Reverb Time is this constant, 0.05, times the cubic volume of the room, divided by the total sound absorptivity in the room. So we have two principal acoustic properties that we can adjust to drive Reverb Time. For a longer Reverb Time, we can work the top of this equation and seek out a larger room ...
