A music composition, editing, and playback system and method provides a user interface design based on geometric interpretation of music theory replacing traditional modern music notation with geometric shapes including chords represented by polygons that are colored with colors or hues.

The present disclosure is directed at methods and systems for implementing and scoring a vocal improvisation feature in a music video game. This feature can allow players of music video games to sing improvised harmonies for a song using a microphone controller. The improvised harmonies can be musically consonant with a pre-authored melody track programmed into the music video game. The improvised harmonies can comprise pre-authored notes programmed into the pre-authored melody track, or can be generated by the music video game during run-time based on the pre-authored melody track. The music video game can also display guidelines visually showing permissible harmony tracks in relation to the pre-authored melody track.

System, apparatus and method for determining semantic information from audio, where incoming audio is sampled and processed to extract audio features, including temporal, spectral, harmonic and rhythmic features. The extracted audio features are compared to stored audio templates that include ranges and/or values for certain features and are tagged for specific ranges and/or values. The semantic information may be associated with audio signature data Extracted audio features that are most similar to one or more templates from the comparison are identified according to the tagged information. The tags are used to determine the semantic audio data that includes genre, instrumentation, style, acoustical dynamics, and emotive descriptor for the audio signal.

The present invention relates to a method and system for analysing audio (eg. music) tracks. A predictive model of the neuro-physiological functioning and response to sounds by one or more of the human lower cortical, limbic and subcortical regions in the brain is described. Sounds are analysed so that appropriate sounds can be selected and played to a listener in order to stimulate and/or manipulate neuro-physiological arousal in that listener. The method and system are particularly applicable to applications harnessing a biofeedback resource.

A method for generating a musical score, a device, and a computer-readable storage medium. The method includes: obtaining target audio; generating a chromagram of the target audio corresponding to each pitch class, utilizing the chromagram to identify a chord of the target audio, and obtaining chord information; performing mode detection on the target audio, and obtaining original key information; performing rhythm detection on the target audio and obtaining the beats per minute; performing identification on a beat type of each audio frame of the target audio, and determining an audio time signature on the basis of a correspondence relationship between a beat type and a time signature; utilizing the chord information, the original key information, the beats per minute, and the audio time signature and performing musical score rendering, and obtaining a target musical score.

A non-transitory computer-readable storage medium storing an evaluation program that causes a computer to execute a process, the process comprising obtaining a captured image captured by an imaging device, displaying the plurality captured images on a display device and displaying a display that indicates a separation between a plurality of set areas set in the captured image while superimposing on the captured image, and detecting timings at which each of a plurality of persons beat rhythm by analyzing the captured images, each of the plurality of persons being included in each of the plurality of set areas.

An apparatus comprises a dereverberation module for generating a dereverberated audio signal based on an original audio signal containing reverberation, and an audio-analysis module for generating audio analysis data based on audio analysis of the original audio signal and audio analysis of the dereverberated audio signal.

To provide a transmission method of an arbitrary signal using an acoustic sound hardly affecting the mood (quality) of the original acoustic sound even if an arbitrary signal within an audible frequency range is combined into the acoustic sound such as music.

The method comprises a step of finding a separable sound, of which a fundamental element (fundamental sound) b2 contributing mainly to recognition of a single sound and an additional element contributing collaterally to recognition of the single sound are separable on temporal axis or frequency axis, among plural sounds composing the acoustic sound, or inserting a separable sound into the plural sounds composing the acoustic sound. The additional element of the separable sound found or inserted is transcribed by a signal pattern b1-1, b1-2 of the arbitrary signal. By means of the acoustic sound of which additional element is transcribed, the arbitrary signal b1-1, b1-2 is transmitted. The additional element may be a sound generated when transmitting vibration energy to a resonance body (resonant body). The fundamental element may be a sound produced according the own resonance mode (resonant mode) by the resonance body (resonant body) receiving the vibration energy.
