摘要： A recorded data processing method includes calculating, for each of N (N is a natural number of three or more) recorded data pairs each formed by two pieces of recorded data that are adjacent to each other when N pieces of recorded data each representing a recording target including at least one of audio or an image are arranged cyclically, a time difference between time signals representing temporal changes of the recording target in the two respective pieces of recorded data of the recorded data pair. It is also evaluated whether or not the N pieces of recorded data include recorded data having no relation according to a total value of N time differences calculated for the N recorded data pairs.

摘要： In a sound processing apparatus, a likelihood calculation unit calculates an in-region coefficient and an out-of-region coefficient indicating likelihood of generation of each frequency component of a sound signal inside and outside a target localization range, respectively, according to localization of each frequency component. A reverberation analysis unit calculates a reverberation index value according to the ratio of a reverberation component for each frequency component. A coefficient setting unit generates a process coefficient for suppressing or emphasizing a reverberation component generated inside or outside the target localization range, for each frequency component of the sound signal, on the basis of the in-region coefficient, the out-of-region coefficient and the reverberation index value. A signal processing unit applies the process coefficient of each frequency component to each frequency component of the sound signal.
