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.

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.

Sound processing apparatus

Signal processing section of a terminal converts acquired audio signals of a plurality of channels into frequency spectra set, calculates sound image positions corresponding to individual frequency components, and displays, on a display screen, the calculated sound image positions results by use of a coordinate system having coordinate axes of the frequency components and sound image positions. User-designated partial region of the coordinate system is set as a designated region and an amplitude-level adjusting amount is set for the designated region, so that the signal processing section adjusts amplitude levels of frequency components included in the frequency spectra and in the designated region, converts the adjusted frequency components into audio signals and outputs the converted audio signals.
