  • Patent number: 8952233
    Abstract: A music tempo calculation system uses a microphone to input ambient music; the input is then processed in real time to display beats per minute (BPM). Input from the microphone is decomposed by a detector into a plurality of digital signals ranging from a most sensitive signal to a least sensitive signal. A software-implemented algorithm is applied to the time between peak music values to determine tempo. BPM is then output to a display to provide feedback to performing musicians regarding tempo. The sensitivity of the detector adjusts automatically to compensate for changes in music volume. In another embodiment, the calculated tempo is used to control motors used to animate toys. Once BPM is known, the moment of an upcoming beat can be anticipated. It then becomes possible to start, stop, and reverse directions of a motor in anticipation of an upcoming beat thereby providing the appearance the animated toy is responding to music beat.

  • Patent number: 8829322
    Abstract: Computer-based methods infer a metrical grid from music that has been input without a predetermined time signature or tempo, enabling such free rhythm input to be annotated with the inferred grid, and stored and transcribed as a musical score. The methods use Bayesian modeling techniques, in which an optimal metrical grid is inferred by identifying the metrical grid that best explains the given sequence of notes by maximizing the posterior probability that it represents the note sequence. Prior musical input from a given user as well as explicit information about the musical style of the input may be used to improve the accuracy of the transcription.

  • Patent number: 8704068
    Abstract: The invention generally pertains to a hand-held computing device. More particularly, the invention pertains to a computing device that is capable of controlling the speed of the music so as to affect the mood and behavior of the user during an activity such as exercise. By way of example, the speed of the music can be controlled to match the pace of the activity (synching the speed of the music to the activity of the user) or alternatively it can be controlled to drive the pace of the activity (increasing or decreasing the speed of the music to encourage a greater or lower pace). One aspect of the invention relates to adjusting the tempo (or some other attribute) of the music being outputted from the computing device. By way of example, a songs tempo may be increased or decreased before or during playing. Another aspect of the invention relates to selecting music for outputting based on tempo (or some other attribute). For example, the computing device may only play songs having a particular tempo.

    Abstract: A music application guides a user with some musical experience through the steps of creating and editing a musical enhancement file that enhances and plays in synchronicity with an audio signal of an original artist's recorded performance. This enables others, perhaps with lesser musical ability than the original artist, to play-along with the original artist by following melodic, chordal, rhythmic, and verbal prompts. The music application accounts for differences in the timing of the performance from a standard tempo by guiding the user through the process of creating a tempo map for the performance and by associating the tempo map with MIDI information of the enhancement file. Enhancements may contain MIDI information, audio signal information, and/or video signal information which may be played back in synchronicity with the recorded performance to provide an aural and visual aid to others playing-along who may have less musical experience.

    Abstract: The recommended playlist creating section generates several recommended candidate playlists having different reproduction orders as recommended candidate playlists each indicating a recommended reproduction order when one or more contents are sequentially reproduced. The evaluating section evaluates how each of the recommended candidate playlist is close to the ideal fluctuation stored in the ideal fluctuation storing section. The recommended playlist creating section selects a recommended playlist from among the recommended candidate playlists based on a result of evaluation by the evaluating section. This present invention is applicable to a content reproducing unit having a playlist creating function.

  • Patent number: 7741554
    Abstract: A plurality of template data files are provided, each designating a structure and conditions of a music piece, and having a plurality of tracks, each track being assigned to a particular instrument group and defining a time progression structure of music to be performed by the assigned instrument group by setting performance sections at time positions to be performed by the assigned instrument group along the time progression of music. A plurality of component data files are provided, each representing a length of musical phrase that constitutes a predetermined tone progression pattern of a predetermined tone color for a performance by a particular instrument group. When conditions such as a tempo for a music piece to be created are given, a template data file that satisfies the given conditions is selected. Then, component data files are picked up according to the conditions designated by the selected template data file and the musical phrases are placed on the tracks in the template data file.

  • Patent number: 7705230
    Abstract: The invention generally pertains to a hand-held computing device. More particularly, the invention pertains to a computing device that is capable of controlling the speed of the music so as to affect the mood and behavior of the user during an activity such as exercise. By way of example, the speed of the music can be controlled to match the pace of the activity (synching the speed of the music to the activity of the user) or alternatively it can be controlled to drive the pace of the activity (increasing or decreasing the speed of the music to encourage a greater or lower pace). One aspect of the invention relates to adjusting the tempo (or some other attribute) of the music being outputted from the computing device. By way of example, a songs tempo may be increased or decreased before or during playing. Another aspect of the invention relates to selecting music for outputting based on tempo (or some other attribute). For example, the computing device may only play songs having a particular tempo.

  • Patent number: 7645929
    Abstract: Various method and system embodiments of the present invention are directed to computational estimation of a tempo for a digitally encoded musical selection. In certain embodiments of the present invention, described below, a short portion of a musical selection is analyzed to determine the tempo of the musical selection. The digitally encoded musical selection sample is computationally transformed to produce a power spectrum corresponding to the sample, in turn transformed to produce a two-dimensional strength-of-onset matrix. The two-dimensional strength-of-onset matrix is then transformed into a set of strength-of-onset/time functions for each of a corresponding set of frequency bands. The strength-of-onset/time functions are then analyzed to find a most reliable onset interval that is transformed into an estimated tempo returned by the analysis.

  • Patent number: 7622664
    Abstract: A performance control apparatus which can actually reproduce performance information without a long sounding blank time period being produced even if the performance information includes information indicative of a long sounding blank time period. Performance data md-A including at least key-on event data KON and time data TIME that defines sounding timing is read out and output. When the time data TIME in the readout performance data md-A is indicative of a longer sounding blank time period than a predetermined time period, the sounding blank time period is reduced or eliminated in outputting the performance data md-A.
