These parameters correspond to the many natural acoustic factors that create the sound field you experience in an actual concert hall or ...
35 3-2. Descriptions of the digital sound field parameters not all of the following parameters are found in every program. ● init dly (initial delay) how it affects the sound: changes the apparent distance from the source sound. Since the distance between a sound source and a reflective surface dete...
36 ● rev. Time (reverberation time) how it affects the sound: the natural reverberation time of a room depends primarily on its size and the characteristics of its inner surfaces. This parameter, therefore, changes the apparent size of the acoustic environment over an extremely wide range. What it d...
