摘要： Characteristic amounts are calculated from each of multiple musical piece contents, and then time points when the characteristic amounts exceed a threshold are detected as cut points. Information on the cut point concerning each of the multiple musical piece contents is stored. Based on the stored information on the cut point, a judgment is made as to whether the multiple musical piece contents match each other.

摘要： Provided is a recording or playback apparatus capable of separating a musical piece from an audio including the musical piece and a speech through a simple arithmetic process. A cut point detector detects, as a cut point, a time point at which an audio signal level or an amount of change in the audio signal level is not lower than a predetermined value. A frequency characteristic amount calculator calculates a characteristic amount in a frequency area of the audio signal only at each cut point and in its proximity. A cut point judging unit judges an attribute of the cut point on a basis of the calculated characteristic amount of the frequency. A music section detector detects a start and end points of each music section on a basis of the attribute and an interval between sampling points.

摘要： An audio variation point detector detects whether a variation amount of audio power of the received audio signal is greater than a first threshold, and detects a variation point where the audio power variation is greater than the first threshold. A song detector determines whether the vicinity of the detected variation point is a song, based on a feature amount in a frequency domain of the audio signal in the vicinity of the variation point, and detects a song based on the determination. A chorus position detector detects, as a chorus position candidate, a position where the variation amount of audio power takes a maximum value in the detected song, determines whether a likelihood between a reference feature amount and the feature amount in the frequency domain of the detected chorus position candidate is greater than a second threshold, and detects the chorus position candidate as a chorus position if the likelihood is greater than the second threshold.

The first liquid crystal layer has the liquid crystal alignment properties of the first transparent resin layer. Next, the process involves forming a second transparent resin layer with different liquid crystal alignment properties on the first polymer liquid crystal layer, then forming a second polymer liquid crystal layer on the second transparent resin layer in the same manner.

摘要： An intake air amount controlling apparatus of an engine is provided. The apparatus comprises an intake manifold that is branched from an intake manifold collecting portion of the engine. The intake manifold communicates with an intake port of a cylinder head of a corresponding cylinder. The apparatus further comprises a throttle valve in the intake manifold of the cylinder and a throttle bore provided in the intake manifold. The throttle bore has a curved surface. The throttle valve rotates such that one half of the throttle valve contacts with the curved surface of the throttle bore until the throttle valve reaches a predetermined opening degree. Thus, an air flow via the one half of the throttle valve is prevented from entering the intake port. An air flow via the other half of the throttle valve is allowed to enter the intake port. Areas of cross sections, which are orthogonal to an air flow passing in the intake manifold, of the intake manifold at upstream and downstream of the throttle valve are larger than an area of a cross section, which is orthogonal to an air flow entering the intake port, crossing an open face at which the intake manifold communicates with the intake port.
