Abstract: The present invention relates to an information processing apparatus, method, and program that are capable of analysing a waveform of a tune involving a modulation with a reduced operation amount. A beat feature extraction section 41 extracts a feature related to a beat from sections of a waveform of a tune involving a modulation, each of the sections corresponding to each beat. A beat feature removal section 42 removes a phase component from a frequency component of each feature extracted. An autocorrelation map generation section 43 generates, based on the features whose phase components have been removed, autocorrelation information representing correlation between one section and another section. This enables the waveform of the tune involving a modulation to be analyzed with a reduced operation amount. The present invention is applicable to an information processing apparatus.

Abstract: Described are methods, systems, and apparatuses, including computer program products, for scoring a musical performance after a period of ambiguity in a rhythm-action game. This is accomplished by displaying a first target music data and a second target music data where the first target music data's tolerance threshold overlaps with a second target music data's tolerance threshold. When a music performance input data is received, the game platform determines if the music performance input data is within both tolerance thresholds. Then scores are determined, based on a degree of matching between the music performance input data and the first target music data and between the music performance input data and the second target music data. The game platform then assigns the music performance input data to whichever target music data has the higher score when the difference between the first and second scores is greater than a predetermined value.

Abstract: During operation, a “coarse search” stage applies variable-scale windowing on the query pitch contours to compare them with fixed-length segments of target pitch contours to find matching candidates while efficiently scanning over variable tempo differences and target locations. Because the target segments are of fixed-length, this has the effect of drastically reducing the storage space required in a prior-art method. Furthermore, by breaking the query contours into parts, rhythmic inconsistencies can be more flexibly handled. Normalization is also applied to the contours to allow comparisons independent of differences in musical key. In a “fine search” stage, a “segmental” dynamic time warping (DTW) method is applied that calculates a more accurate similarity score between the query and each candidate target with more explicit consideration toward rhythmic inconsistencies.
