发明名称 COMPACT DISK AND ITS SOUND FIELD REPRODUCING DEVICE
摘要 PURPOSE:To execute reproduction being faithful to an original sound by calculat ing and reproducing an arrival time and an attenuation quantity of a sound generated from a sound source from sound source position information of each sound source and a listener's listening position at the time of reproduction by discriminating and recording sound source position information and sound signal information with regard to the respective sound sources in a disk of a standard of a CD-I. CONSTITUTION:This device is provided with a CD-I disk 4 in which sound source position information reproduced at every sound source is recorded, and the respective sound source signal information is interleaved and recorded in different channels, plural compressed music signal expanding parts 7, 8 in addition to a conventional CD-I player, and acoustic effect parts 9, 10. Also, this device is constituted of a control part 2 for setting attenuation quantities 18, 20 and time delay elements 17, 19 to each acoustic effect part 9, 10 from listening position information and sound source position information by selecting the compressed music signal expanding part reproduced by a channel number, and inputting listener's listening position information 16.
