Abstract: Systems and methods for editing a computer-base musical score include detecting a collision between objects placed in the score and automatically moving one of the colliding objects out of the way to eliminate the collision. Selection of the object to be moved is based on a comparison of the priority levels of the colliding objects. To enhance clarity and legibility of the score, objects are organized into groups of similar type objects. Groups are treated as a single object for the purposes of avoiding collisions. Certain object types are transformed, including scaled, rotated, or sheared, to avoid collisions.

Abstract: A combination distortion pedal and amplifier includes a foot pedal controls the distortion and the amplification of audio signals. The level of distortion and amplification are determined by the position of the foot pedal with a low level of distortion and amplification when the foot pedal is in a released position and a high level of distortion and amplification when the foot pedal is depressed. Various intermediate distortion and amplification levels are provided when the foot pedal is in positions between fully released and fully depressed.

Abstract: A dual-frequency coaxial earphone includes a frame, a shared yoke, a high frequency speaker part, and a low frequency speaker part. The high frequency speaker part and the low frequency speaker part are coaxially arranged at inside and outside of the shared yoke, and are coaxial with a central opening of the frame. Further, a permanent magnet of the higher frequency speaker part is contrary, in polarity, to an annular magnet of the low frequency speaker part. Therefore, acoustic frequency of the low frequency speaker part can be phase-countered by passing thereof through an acoustic annular recess, so that the acoustic frequency of the low frequency speaker part has the same phase as the acoustic frequency of the high frequency speaker part and both then are output synchronally. The high frequency speaker part and the low frequency speaker part can then be separated, in acoustic frequency, from each other.

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: In a filter device, a filter coefficient calculation circuit has a parameter table. The parameter table stores a plurality of sets of filter coefficients associated with a first parameter based on a frequency and a second parameter based on respective plurality of levels representing a degree of attenuation or enhancement of a gain of a filter in filter characteristics. The filter coefficient calculation circuit extracts a set of filter coefficients from a parameter table with the use of the first parameter and the second parameter determined according to a frequency and a strength of a musical sound signal, and outputs the extracted set of filter coefficients to the filter. The filter circuit performs filter processing for the musical sound signal, based on the filter characteristics determined by the set of filter coefficients.

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.

Abstract: Methods, systems, and computer program products for selection of visually displayed audio data are provided. In one implementation, a computer-implemented method is provided. Original audio data is displayed in a plurality of visual forms. A first input is received selecting a region within a first visual representation of the original audio data. A second input is received selecting a region within a second visual representation of the original audio data. Audio components from the selected regions are isolated to provide isolated audio data. The isolated audio data corresponds to audio data common to both user selected regions. The isolated audio data is edited and then missed into the original audio data.

Abstract: This invention provides a signal processing and signal synthesis technique from a family of signal processing and signal synthesis techniques designed to readily interwork or be used individually in creating new forms of rich musical timbres. Phase staggered multi-channel signal panning creates spatial perturbation and chase effects for subtle or dramatic application, and may be swept with control signals from a low-frequency oscillator, transient envelope, or other source. Phase-staggering and modulation parameters may be recalled from stored program control or modulated in real-time by arbitrary control signals, including those derived from the original input signal. The invention may be used individually or in conjunction with other signal processing and signal synthesis techniques in creating new forms of rich musical timbres. The invention may also be used in spatially-distributed timbre construction.

Abstract: An entertainment system has a music storage system storing a plurality of music pieces, a playback system coupled with the music storage system, a navigation system providing current map information including a present location, wherein a current map has a plurality of zones each being assigned to one of a plurality of zone types, and a controller for controlling playback of selected music pieces, wherein the controller maintains a plurality of playlists, each having a plurality of music pieces and being assigned to at least one zone type. The controller receives information of a present location and a current zone type and selects an assigned playlist, wherein the navigation system further provides information about a distance and/or time to a next zone. The controller modifies the assigned playlist such that a transition to the next zone is timely synchronized with the ending of a music piece of the assigned playlist.
