PURPOSE:To reproduce an original acoustic field feeling in a state more close to be natural with much less data by grasping acoustic space information and compressing real acoustic field data. CONSTITUTION:The acoustic field data extracter to extract acoustic field data to be set to an echo adder 200 from the sound field data of pulse sequences measured in an acoustic space is provided with a loudness processing part 1 to form the new pulse sequence by dividing the data of the pulse sequence into prescribed lengths and transforming the data contained in this block into the volume of sounds for each block, and a peak detector 3 to divide the new pulse sequence into prescribed blocks and to define the new pulse at the maximum level in this block as a coefficient set to the echo adder 200. |
