Title:
高音質化装置及び方法、並びにコンピュータプログラム
Document Type and Number:
Japanese Patent JP4371246
Kind Code:
B2
Abstract:
A sound-quality enhancing device has delay elements for delaying a processed sound signal generated by subjecting an original sound signal to a predetermined type of processing by a predetermined time thereby to generate a basic sound signal, delaying the processed sound signal by a time shorter than the predetermined time thereby to generate a backward sound signal, and delaying the processed sound signal by a time longer than the predetermined time thereby to generate a forward sound signal. The sound-quality enhancing device further has effect sound generating elements for generating an effect sound signal producing an effect sound added to the basic sound generated by a basic sound signal from at least the generated backward and forward sound signals and combining elements for adding the generated effect sound signal to the basic sound signal.
