- * The reverberation parameters provided by ReverbType consist

- * Early reflections are the initial individual low-order reflections of the
- * direct signal off the surfaces in the room.
- * The late Reflections are the dense, high-order reflections that characterize
- * the room's reverberation.
- * The delay times for the start of these two reflection types give the listener
- * a sense of the overall size and complexity of the room's shape and contents.
- * The larger the room, the longer the reflection delay times.
- * The early and late reflections' intensities define the gain (in decibels) of the reflected
- * signals as compared to the direct signal. These intensities give the
- * listener an impression of the absorptive nature of the surfaces and objects
