DATA RECORDING AND REPRODUCING APPARATUS, METHOD OF RECORDING AND REPRODUCING DATA, AND RECORDING MEDIUM FOR PROGRAM THEREFOR

摘要

A data recording and reproducing apparatus (100) is described. This apparatus is adapted to receive audio data created by encoding an original sound signal and to decode the audio data into the original sound signal to thereby reproduce the original sound signal is disclosed. The data recording and reproducing apparatus (100) includes: data storage means for storing the audio data; feature point information creation means (35,45) for creating information about feature points by extracting information about characteristics of sound indicated by the original sound signal from the audio data stored in the data storage means and by creating feature point information based on the extracted information about the characteristics; and altered-speed reproduction means (28,42) for reproducing the original sound signal at an altered speed by decoding the audio data and thinning out the decoded audio data based on the feature point information.
