Computer-based systems, devices, and methods for assigning mood labels to musical compositions are described. A mood classifier is trained based on mood-labeled musically-coherent segments of musical compositions and subsequently applied to automatically assign mood labels to musically-coherent segments of musical compositions. In both cases, the musically-coherent segments are generated using automated segmentation algorithms.

A method for generating a musical composition based on user input is described. A first set of musical characteristics is extracted from a first input musical piece. The first set of music characteristics is prepared as an input vector into an unsupervised neural net comprised of a plurality of computing layers by perturbing the first set of musical characteristics according to a user intent expressed in the user input to create a perturbed vector. The perturbed vector is input into the first set of nodes of the unsupervised neural net. The unsupervised neural net is operated to calculate an output vector from a highest set of nodes. The output vector is used to create an output musical piece.

Systems and methods selectively mix a first and second song together during a live performance. The first song has a plurality of first stems, each having stereo audio that combine to form the audio of the first song. The second song has a plurality of second stems, each having stereo audio that combine to form the audio of the second song. A computer, with memory and a processor, executes machine readable instructions of a multiple channel audio mixing application with stored within the memory. The multiple channel audio mixing application plays and mixes audio of at least one of the first stems with audio of at least one of the second stems. The multiple channel audio mixing application is controlled in real-time during the performance to select the at least one first stem and the at least one second stem for the mixing.

A method for providing one or more outputs at one or more respective time instants is provided. The method comprises generating a data object executable to provide an output, placing the object in a position in a sequence, and executing the object at said position in said sequence to provide said output. Each position in the sequence represents a time instant.

An information processing apparatus is provided which includes a music analysis unit for analyzing an audio signal serving as a capture source for a sound material and for detecting beat positions of the audio signal and a presence probability of each instrument sound in the audio signal, and a capture range determination unit for determining a capture range for the sound material by using the beat positions and the presence probability of each instrument sound detected by the music analysis unit.

The apparatus displays, on a display screen, an icon placement region having a time axis defined therein, and displays, in accordance with an input instruction, an icon image with which feature amount information of material data indicative of a sound material is associated. The apparatus further sets a type of a feature amount database, where material data and feature amount information of the material data are associated with each other, along the time axis in accordance with an input instruction. Then, the apparatus references the feature amount database of a type having correspondence relationship in time axis with an icon image to identify material data similar to the feature amount information corresponding to the icon image, and audibly generates a sound at timing corresponding to a position, on the time axis, of the icon image and with content corresponding to the identified material data.

In a method for delivering signaling tones to signaling devices or signaling systems, a signaling tone sequence is selected from a set of undelivered signaling tone sequences. The selected signaling tone sequence is removed from the set of undelivered signaling tone sequences, and the selected signaling tone sequence is delivered.

摘要:
A method and a device for the music generation are disclosed. The method and device, in at least one embodiment, are advantageously used for generating music in response to of an external process by using material from at least two musical themes. Via musical generators for different types of parts, music is generated from material from parts of the respective type of parts of the musical generators from those musical themes, which include parts of the specific type of part of a generator.
摘要:
A procedure for generating different variations of a sequence of symbols, such as a musical piece, based on the properties of a chaotic system--most notably, sensitive dependence on the initial condition--is described and demonstrated. This method preferably uses a fourth order Runge-Kutta implementation of a chaotic system. Bach's Prelude in C Major from the Well-Tempered Clavier, Book I serves as the illustrative example since it is well-known and easily accessible. Variations of the Bach can be heard that are very close to the original while others diverge further. The system is designed for composers who, having created a through-composed work or section, would like to further develop their musical material. The composer is able to interact with the system to select various versions and change them, if desired. Yet the compositional character of the variations remains within the artist's domain of style, expression and inventiveness. The procedure, however, is more generically applicable to other dynamic symbol sequences than music, as well.
