Inventor: AKUNE MAKOTO
IPC: H03M3/02
Filed: 2004-12-13
Abstract: <P>PROBLEM TO BE SOLVED: To obtain a high quality audio signal by making full use of a full frequency range of a high-speed 1 bit audio signal.  <P>SOLUTION: A high-pass signal out of audible band is generated by a dither generation section 14. The frequency property is limited by a BP filter property generation section 32, an Frequency property gradient calculation section 93 and a filter property generation section 94 in a normalization section 16<SB>3</SB>. The power is normalized and then added so that it is smoothly attached to an over-sampled PCM signal. The addition output is additionally over-sampled before ΔΣmodulating to generate 1 bit audio signal. Since the 1 bit audio signal is added a signal exceeding the PCM signal frequency band, whose gradient is calculated by the Frequency property gradient calculation section 93, a natural feeling of auditory sound image with its depth feeling growing back and forth can be created.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
