To get your hands dirty quickly here is an example scene that will get you up and running within a minute. This example demonstrates a very reverberant hall in which a listener and sound source are placed, separated by a low wall. The sound that is emitted by the source is a short click to make the acoustical properties of the hall explicitely audible. The result that is given below features some very distinct early reflections. Over time the response of the room fades into the more gradual tail of the reverberation. A more detailed documentation for all of the features and settings is being worked on. You can download a .zip archive that contains all necessary files from github.
