Apparatus and method for reproducing a sound with its original tone color from data in which tone color parameters and interval parameters are mixed

DETAILED DESCRIPTION Accordingly, it is an object of the present invention to reproduce a sound with its original tone color even when a random access is made on an SMF in which a tone color parameter and an interval parameter are mixed.
In a first aspect of the present invention, the information processing apparatus for processing mixed data, in which, at least, a tone color parameter relating to a tone color and an interval parameter relating to an interval are mixed, includes extracting means for extracting, from the mixed data, the tone color parameter and effective time at which the tone color parameter is made effective, storage means for storing the tone color parameter in a tabular form, reading means for reading the tone color parameter from the storage means in accordance with an input of a playback start position where the playback of the mixed data starts, creating means for creating time information indicating time to set the tone color parameter, read by the reading means, to an electronic apparatus that generates an audio signal based on the mixed data, and output means for outputting the tone color parameter, read by the reading means, together with the time information corresponding to the tone color parameter, and then the mixed data from the playback start position thereafter.
In a second aspect of the present invention, the information processing method for processing mixed data, in which, at least, a tone color parameter relating to a tone color and an interval parameter relating to an interval are mixed, includes the steps of extracting, from the mixed data, the tone color parameter and effective time at which the tone color parameter is made effective, storing the tone color parameter in a tabular form, reading the tone color parameter stored in the storing step, in accordance with an input of a playback start position where the playback of the mixed data starts, creating time information indicating time to set the tone color parameter read in the reading step, to an electronic apparatus that generates an audio signal based on the mixed data, and outputting the tone color parameter read in the reading step, together with the time information corresponding to the tone color parameter, and then the mixed data from the playback start position thereafter
