Yuuji Murai has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7495166
    Abstract: A sound-processing apparatus is provided that is capable of creating a sound effect without having to worry about changes in parameters such as the beat of the input sound source. The sound-processing apparatus comprises: a delay unit DB that generates at least one or more new synchronized sound signal that is synchronized with a sound signal Si to be modulated; parameter-detection unit 6 that detects a parameter that indicates an attribute of the generated synchronized sound signal; a signal-conversion unit 8 that generates a converted signal Sdm based on the detected parameter; and a modulation unit that modulates the sound signal based on the generated converted signal Sdm.
    Type: Grant

  • Publication number: 20060146659
    Abstract: A beat density detecting apparatus and an information playback apparatus are provided to detect distinctive characteristics that music or the like has and to provide the same as a novel information volume. Playback data read out from an information recording medium, such as an optical disc, and sub-code data containing the information of an elapsed track time indicating a recording position of the playback data are provided to a beat detecting unit and a beat position detecting unit, respectively. The beat detecting unit detects the number of occurrences of a change in amplitude at each predetermined frequency of the playback data, and the beat position detecting unit detects an elapsed track time from the sub-code data. Further, a beat density computing unit finds the number of occurrences with respect to the elapsed track time as the characteristics information of a beat density.

  • Patent number: 6654317
    Abstract: A method for reproducing information, comprising the steps of: reading compressed audio data from an information recording medium in which the compressed audio data is recorded in a frame unit; and subjecting the compressed audio data thus read to an expansion processing to reproduce same. When an instruction is given to make a special reproduction in which a frame region to be reproduced and an other frame region not to be reproduced are mixed, control is made so that the compressed audio data in respective frames are successively reproduced in the frame region to be reproduced, and a header information for the respective frames is read out in the other frame region not to be reproduced, and determination on a leading position of a subsequent frame is made on a basis of the header information, thereby conducting a successive migration for the respective frames.
