Abstract: A signal processing method includes receiving a signal that rises in response to a physical change and falls in response to an opposite physical change that is opposite to the physical change from a sensor that is a stretchable sensor and outputs the signal, and correcting a signal lag as either a rising of a received signal that has been received from the sensor lags with respect to a falling of the received signal, or the falling of the received signal lags with respect to the rising of the received signal.

Abstract: A recorded data processing method includes: for each of N recorded data pairs each formed by two pieces of recorded data X that are adjacent to each other when N pieces of recorded data X each representing a recording target including at least one of audio and video are arranged cyclically, calculating a plurality of candidate values for a time difference between time signals representing temporal changes of the recording target in the two respective pieces of recorded data X of the recorded data pair; and identifying one of the plurality of candidate values in each of the N recorded data pairs as the time difference between the two pieces of recorded data in the recorded data pair such that a numerical value obtained by summing, over the N recorded data pairs, one of the plurality of candidate values calculated for each of the N recorded data pairs approaches zero.

Abstract: A sound processing apparatus has one or more of processors configured to suppress peaks that exist in a high-order region of a cepstrum of a sound signal and that correspond to a harmonic structure of the sound signal. The processor is further configured to generate a separation mask used to suppress a harmonic component or a nonharmonic component of the sound signal based on a resultant cepstrum in which the peaks of the high-order region have been suppressed.

Abstract: 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.
