Abstract: A media application for providing outputs (e.g., audio outputs) in response to inputs received from an input device is provided. The media application may connect input mechanisms of an input device with parameters of channel strips (e.g., which may define output sounds) using an intermediate screen object. The media application may first assign an input mechanism to a screen object, and separately map a screen object to a channel strip parameter. The media application may map a screen object to several channel strips simultaneously such that, based on the value of the screen object, the volume of each of the several channel strips changes. The media application may provide a graphical representation of available channel strips using layers. As the media application accesses a channel strip, the appearance of the portion of the layer associated with the channel strip may change.

Abstract: A computer implemented method allows a user to adjust tracks in a musical arrangement. The method involves a user selecting a musical position of an audio track, which the user desires to adjust in time, either by compressing it or expanding it, by indicating with a pointing device, such as a mouse, the position in the time line of the audio track that the user wishes to alter. A first marker is then displayed at the selected musical position in the audio track. Boundary markers defining transients in the audio signal surrounding the selected musical position are then automatically generated by analysis of the audio signal, and are displayed on the audio track. The two boundary markers define an audio segment that is to be adjusted in tempo by the user moving the first marker along the time line.

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: 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.
