Sound field parameter Liveness Sur. Liveness SB. Liveness Graphical user interface (GUI) menu Features Liveness. Surround and surround back liveness. Adjusts the reflectivity of the virtual walls in the hall by changing the rate at which the early reflections decay. The early reflections of a sound source decay much faster in a room with acoustically absorbent wall surfaces than in one which has highly reflective surfaces. A room with acoustically absorbent surfaces is referred to as "dead", while a room with highly reflective surfaces is referred to as "live". This parameter lets you adjust the early reflection decay rate and thus the "liveness" of the room. Control range: 0 to 10 Source sound Live Dead Level Level Level Time Time Time Rev. Time Small reflected sound Large reflected sound Small value = 0 Large value = 10 Reverberation time. Adjusts the amount of time taken for the dense, subsequent reverberation sound to decay by 60 dB at 1 kHz. This changes the apparent size of the acoustic environment over an extremely wide range. Set a longer reverberation time to get more sustaining reverberation sound, and set a shorter time to get articulate sound. Control range: 1.0 to 5.0 s Reverberation 60 dB Source sound Reverberation Early reflections 60 dB 60 dB Rev. Time Sound source Short reverberation Rev. Time Rev. Time Long reverberation Rev. Delay Small value = 1.0 s Large value = 5.0 s Reverberation delay. Adjusts the time difference between the beginning of the direct sound and the beginning of the reverberation sound. The larger the value, the later the reverberation sound begins. A later reverberation sound makes you feel as if you are in a larger acoustic environment.
