摘要： The present disclosure describes techniques for melody extraction. The techniques comprise receiving a polyphonic symbolic music file. The polyphonic symbolic music file may comprise a plurality of notes. The polyphonic symbolic music file may be converted to a plurality of feature vectors. Each of the plurality of feature vectors may be a multidimensional vector. Each of the plurality of feature vectors may correspond to a particular note of the plurality of notes. The plurality of feature vectors corresponding to the plurality of notes may be classified using a model that is trained to determine whether each of the plurality of notes belongs to a melody based on the plurality of feature vectors.

摘要： A system for processing digital audio signals. The system includes a digital audio unit configured to provide digital audio data of a first audio track and a second audio track. The first audio track and a second audio track represent different versions of the same piece of music. The system also includes a user control device operable by a user to allow the user to select either a first region or a second region. The digital audio unit is configured to play back audio signals obtained from the first audio track when the first region is selected, and to play back audio signals obtained from the second audio track when the second region is selected.

摘要： A newly composed musical piece is generated with original music as an input.
The present disclosure relates to a music processing system. And the music processing system of the present disclosure is a music processing system characterized by having musical-piece generating means which generates a musical piece by using a learning model which performed machine learning on the basis of input data including musical piece data in which a musical score of a musical piece constituted by one channel or more of melodies and one channel or more of chords is described and configuration information indicating attributes of elements constituting the musical piece of the musical piece data and shaping means which shapes the generated musical piece generated by the musical-piece generating means to a musically harmonized content.

摘要： A method for generating an audio output is described. Image inputs of interactive movements by a user captured by an image sensor are received. The interactive movements are mapped to a sequence of audio element identifiers. The sequence of audio element identifiers are processed to generate a musical sequence by performing music theory rule enforcement on the sequence of audio element identifiers. An audio output that represents the musical sequence is generated.
