  • Publication number: 20220188062
    Abstract: A skip behavior analyzer is part of a media delivery system that allows for unbiased A/B testing of a plurality of versions of a song. The media delivery system stores a plurality of versions of a song and randomly selects, for each requesting device, a version of the song to associate with that device. Each time the device requests the song, thereafter, the media delivery system will provide the same version of the song for consistency. The media delivery system then gathers song play and skip information, calculates the differences in distribution of the skip behavior, and provides the skip information to allow a music composer to better determine which version of a song is more popular and why that is so.

  • Publication number: 20220059064
    Abstract: A system is provided for editing an audio file. The system displays, on an electronic device, a piano roll. The system receives a user input to cut a segment of the piano roll. The segment of the piano roll includes a respective tone that extends across both sides of the segment of the piano roll, such that the respective tone includes: a first portion of the respective tone that precedes the segment of the piano roll; and a second portion of the respective tone that follows the segment of the piano roll. In response to the user input to cut the segment of the piano roll, the system cuts the segment from the piano roll and, without user intervention, concatenate the first portion of the respective tone with the second portion of the respective tone.

  • Patent number: 11238839
    Abstract: Methods, systems and computer program products are provided for identifying an audio stem. Audio stems (t1, . . . , tN) are stored on a stem database and songs (S1, . . . , SP) made with at least a subset of the plurality of the audio stems (t1, . . . , tN) are stored on a song database. At least partially composed song (S*) having a predetermined number of pre-selected stems (k) are received. In turn, a probability vector (or relevance value or ranking) is produced for each stem (t1, . . . , tN) to be complementary to the at least partially composed song (S*).

  • Patent number: 11145285
    Abstract: The present disclosure relates to a method of editing an audio stream (S) having at least one tone (T1) extending over time in said stream. The method comprises cutting the stream at a first time point of the stream, producing a first cut (A) having a left cutting end (AL) and a right cutting end (AR); allocating a respective memory cell to each of the cutting ends; in each of the memory cells, storing information about the tone; and, for one of the cutting ends, concatenating the cutting end with a further stream cutting end which also has an allocated memory cell with information stored therein about any tones extending to said further cutting end. The concatenating comprises using the information stored in the memory cells for adjusting any of the tones extending to the cutting ends.

  • Publication number: 20210312941
    Abstract: Methods, systems and computer program products are provided for determining acoustic feature vectors of query and target items in a first vector space, and mapping the acoustic feature vectors to a second vector space having a lower dimension. The distribution of vectors in the second vector space can then be used to identify items from the same songs, and/or items that are complementary. A mapping function is trained using a machine learning algorithm, such that complementary audio items are closer in the second vector space than the first, according to a given distance metric.

  • Publication number: 20210158791
    Abstract: The present disclosure relates to a method of automatically preparing a MIDI file based on a target MIDI file comprising respective note information about each of a plurality of target notes and a source MIDI file comprising respective note information about each of a plurality of source notes. Each note information comprises pitch information defining a pitch of the note. The method comprises ranking the plurality of target notes based on the pitch of each target note. The method also comprises, for each of the ranked target notes, removing the pitch information from the note information of the target note. The method also comprises, for each of the ranked target notes, replacing the removed pitch information with pitch information of a corresponding source note, whereby the target note has the same pitch as the corresponding source note, forming a plurality of new notes of a new MIDI file.

  • Publication number: 20210125593
    Abstract: An electronic device segments a first and second MIDI files into pluralities of source segments and target segments. For each of a plurality of consecutive pairs of first and second target segments, the electronic device identifies a first source segment corresponding to the first target segment of the consecutive pair and identifies a second source segment corresponding to the second target segment of the consecutive pair, where the first and second source segments are identified by determining that the first and second source segments are harmonically conformant to the corresponding first and second target segments, and determining that a transition between the first and second source segments is graphically conformant to a transition between a consecutive pair of source segments. The electronic device generates a third MIDI file using the identified first and second source segments for each of the plurality of consecutive pairs of first and second target segments.

  • Patent number: 10600398
    Abstract: A device for generating a real time music accompaniment includes a music input interface, a music mode classifier that classifies pieces of music received at the music input interface into one of different music modes including at least a solo mode, a bass mode, and a harmony mode, a music storage, and a music output interface. A music selector selects one or more recorded pieces of music as real time music accompaniment to an actually played piece of music received at the music input interface, wherein the one or more selected pieces of music are selected to be in a different music mode than the actually played piece of music. A music output interface outputs the selected pieces of music.

  • Publication number: 20200074343
    Abstract: A training set for use during content generation is generated by applying a first machine learning process P1 to a first finite sequence s wherein s has a length Ls, to generate a first statistical model M(s). The first statistical model M(s) is sampled using a first sampling process G to generate a second finite sequence t wherein t has a length Lt. A second machine learning process P2 is applied to the second finite sequence t to generate a second statistical model M(t), wherein no substring of the second finite sequence t of length d is identical to a substring of the first finite sequence s, wherein d is a predetermined number of elements in a sequence.
