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

An 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, the information processing method comprising the steps of:

• extracting, from the mixed data, a chronologically earlier tone color parameter, a chronologically later tone color parameter and respective times corresponding to each tone color parameter;
• comparing a time differential between the chronologically earlier tone color parameter and the chronologically later tone color parameter with a predetermined threshold time;
• storing the chronologically later tone color parameter onto a first memory which also stores the chronologically earlier tone color parameter or onto a second memory, based on a comparison result of the comparing means;
• 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.
