Abstract: The sound reproducer (100) generates and outputs, when any external situation such as a running sound is recognized by an external input rhythm detecting section (110), generates external rhythm information concerning the recognized running sound. When the external rhythm information is acquired, a rhythm setting section (173) of a processing section 170) generates set rhythm information for setting a rhythm of a music corresponding to the rhythm of the running sound. Because of this feature, even when a running state of the vehicle changes, the sound reproducer (100) can reproduce a rhythm of a music with a rhythm corresponding to the running state. Because of this feature, the music can be reproduced in better conditions in correspondence to the external situation.

Abstract: An apparatus is to analyze music data of a musical performance including note events of triplets as well as note events like triplets, and to display the note events in triplet notation properly in view of the general rhythmic tendency of the musical performance. Music data representing a musical performance is analyzed by counting the number of note events which occur as a regular rhythm pattern and the number of note events which occur as a triplet, so that the performed music as a whole is judged to be either in a triplet-shy rhythm or in a triplet-rich rhythm. Then fuzzy triplet detecting time windows detect triplet candidate notes. Thus detected fuzzy triplet note events are flexibly decided to be notated in a regular rhythm pattern form or in a triplet form depending on whether the performed music as a whole is in a triplet-shy rhythm or in a triplet-rich rhythm. The notes are displayed in the decided form of notation to provide a good-looking and easily understandable music score.

Abstract: A system and methods use music features extracted from music to detect a music mood within a hierarchical mood detection framework. A two-dimensional mood model divides music into four moods which include contentment, depression, exuberance, and anxious/frantic. A mood detection algorithm uses a hierarchical mood detection framework to determine which of the four moods is associated with a music clip based on the extracted features. In a first tier of the hierarchical detection process, the algorithm determines one of two mood groups to which the music clip belongs. In a second tier of the hierarchical detection process, the algorithm then determines which mood from within the selected mood group is the appropriate, exact mood for the music clip. Benefits of the mood detection system include automatic detection of music mood which can be used as music metadata to manage music through music representation and classification.

The rhythm information of the audio signal is established based on the postprocessed rhythm raw-information.

Abstract: A method for the algorithmic expressive intonation tuning (EIT) and performance of electronic, computer and MIDI musical works relies on melodic intervals, rather than on chordal harmony, and acts by desirably modifying the pitch of a note slightly (compared to equal temperament tuning), depending on the next melodic note. This dynamic, non static, melodic tuning emulates, and can even possibly augment, aspects of outstanding live human musical performance achieved with regard to pitch subtleties, as it enhances the living sounding, real aspects of the performance of electronic, computer and MIDI music, by sensibly causing a slightly different pitch of particular notes, depending on the size of an interval and on whether an interval is ascending or descending, with the same note subtly having more than one pitch often, depending on melodic context.

Abstract: A real time, multi-function beat counting system used in machine perception of musical rhythms employs a high speed stable algorithm including down sampling and group summing of the original signal, pulse matching on peak points, and check-frame decision making. The down sampled and group summed signal is utilized to derive an onset peak train formed of a series of data points. The onset peak train is divided into frames, and a threshold value is determined for each frame. In each frame, peak profiles are determined, each comprising successive data points within the frame having values greater than the threshold value. Within each peak profile, a peak point is identified. An algorithm is employed to compare the onset peak train with a plurality of unit data pulse sequences having different periods, and a match is determined between the onset peak train and the closest one of the unit data pulse sequences to identify the period of the rhythm.

Abstract: A method and system for extracting melodic patterns by first recognizing musical “keywords” or themes. The invention searches for all instances of melodic (intervallic) repetition in a piece (patterns). This process generally uncovers a large number of patterns, many of which are either uninteresting or are only superficially prevalent. Filters reduce the number and/or prevalence of such patterns. Patterns are then rated according to characteristics deemed perceptually significant. The top ranked patterns correspond to important thematic or motivic musical content. The system operates robustly across a broad range of styles, and relies on no metadata on its input, allowing it to independently and efficiently catalog multimedia data.
