  • Patent number: 7678984
    Abstract: Method and apparatus for programmatically generating interesting audio file playlists. A playlist generation mechanism may use an N-gram model of audio file ordering patterns found in a collection of human-generated playlists to automatically generate new playlists. Given play histories indicating one or more played audio files as input, statistical methods may be used to look for sequences of audio files that occur a statistically significant number of times in the N-gram model for inclusion in new, interesting playlists that incorporate the human element found in the collection of playlists. In some embodiments, one more backoff probability methods may be used to provide additional candidate audio files for playlists if there is insufficient coverage for an audio file in the N-gram model. In one embodiment, a class-based statistical model incorporating higher-level statistics for the audio files may be used to weight selection of audio file transitions from the N-gram model.

  • Patent number: 6909041
    Abstract: Reverberation characteristics of an original sound field and a reproduction sound field are measured and a difference between the reverberation characteristics is obtained. A reflected sound pattern added to reproduction sound is calculated so that the reverberation characteristics of the reproduction sound field approximate to the reverberation characteristics of the original sound field from the difference between the reverberation characteristics and is added and reproduced in the reproduction sound field. A frequency is divided into predetermined bands and a reflected sound pattern to be added is obtained similarly in the respective bands and is added to the corresponding frequency band of the reproduction sound and reproduced. Measurement of the reverberation characteristics is obtained by inputting an impulse signal to a speaker and collecting a generated sound wave by a microphone provided in a position corresponding to the head of a listener and analyzing the sound wave by an analyzer.

  • Patent number: 6864413
    Abstract: An ensemble system reproduces a performance on an automatic player piano expressed by a set of MIDI music data codes in ensemble with another performance recorded in a compact disc in the form of audio data codes; the ensemble system firstly determines the pitch of the fundamental tone produced through vibrations of a string, then searching the audio data codes for a corresponding tone, calculating a ratio between the pitch of the fundamental tone and the pitch of the corresponding tone, and determining a data read-out speed for the audio data codes; while the MIDI data codes are being supplied to the automatic player piano, the audio data codes are transferred to a speaker system at a speed equal to the product between the standard speed and the ratio so that the piano tones are well harmonized with the electronic tones.

  • Patent number: 6846979
    Abstract: A search list of records is displayed on a display screen DP. Some records may have the same music title as one item, but are different in other items (genre, rhythm, tempo and the like). A favorite list can be formed by a selection process using a mark FMa (reversible by a favorite switch ST0) on each record. A first or second list can be formed by a search process after a search switch SM5 or ST5 is operated. A desired list is selected by using list selection switches ST1 to ST4 and a desired record is designated by a cursor CR to decide a style. The cursor CR can be moved by one record after another by a normal cursor motion switch SM2 or SM3, and jumped to a record group having different item contents by a special cursor motion switch SM1 or SM4.

    Abstract: The present invention relates to a way of presenting a musical composition such as an orchestral piece, a song, jingle, or other musical content (complete or excerpts) as a sort of game made up of component audio tracks. In one preferred embodiment, the individual tracks are defined by layers (also called “segments”) that represent different instruments. For example, in the case of an orchestral music, the layers may represent the sounds made by a violin, flute, trumpet, drum, piano, and so on. The separate digital recordings of each layer then are the audio tracks that become pieces of a puzzle.

  • Publication number: 20040035284
    Abstract: Each time a predetermined type of note controlling performance data (e.g., note-on event data) is detected from among a series of performance data, deviation values for a plurality of channels, varying in deviation state among the channels, are set such that a control value of a predetermined tone characteristic (e.g., event generation timing), included in the note controlling performance data, is caused to vary among the plurality of channels. Then, values, obtained by causing the control value vary among the plurality of channels in accordance with the respective deviation values of the channels, are set as new control values for the corresponding channels. Then, for each of the channels, there is created note controlling performance data of the predetermined type having the corresponding new control value incorporated therein. A break of a phrase in performance data may be detected so that control can be performed per phrase.

  • Patent number: 6642444
    Abstract: Plural part playback channels each play back music performance signals of respectively assigned performance parts selectively in an enhanced mode or in an unenhanced mode. When an enhanced mode is designated for a particular channel 2 (at time A), the channel 2 plays back the music performance signals in a prominent manner and channels 1, 3-6 plays back in a suppressed manner. The tone volume of the channels 1, 3-6 in the suppressed manner is set by manipulating the contrast dial CD. Where the enhanced mode is set for plural channels 2 and 6 (between time C and time D), manipulation of an enhanced mode clear switch SC (at time D) causes cancellation of the prominent manner of playback at the channels 2 and 6 as well as the suppressed manner of playback at the channels 1, 3-5.

  • Patent number: 6541692
    Abstract: Many non-musicians enjoy listening to music, and would like to be able to play along with it, but do not have the talent or the time to learn to play a musical instrument. The system described herein allows non-musicians to follow along with a display that is based on the principles of musical notation, but is designed to be intuitive and require no training to use. The player is guided through the steps of playing a rhythm along with a musical performance, and the system provides the illusion that the player is actually playing a melodic part on an instrument. In addition, the system indicates how closely the player is following the guide, and it also scores the player's performance. The score is used to drive interactive feedback to the player. The system can be configured to work in local area networks or wide area networks with low latency or high latency in the network.
