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.

Systems, processes and device configurations are provided for microphone input devices. A microphone input device can include a plurality of feedback elements positioned along a body and a controller to control the plurality of feedback elements based on feedback from a gaming device. The controller can detect voice input, communicate voice input to the gaming device, and receive feedback for control of the plurality of feedback elements to communicate how well the user is performing. Similarly, the microphone input device may provide haptic feedback in the form of aiding or providing hints for a user. Feedback and haptic output to a user may improve the accessibility of users for gaming devices and singing applications. Processes are provided for controlling a microphone input device including control of feedback elements in response to one or more of voice input, media and a gaming device.

The present application provides a rhythm interaction method and device. The method includes: the first client sending a song identification to a server, the first client playing a song according to the audio data sent by the server, and the first client displaying the rhythm interaction result sent by the server within a preset time period before an end of the playing of the song.

An automatic performance device includes: a pattern storage part, storing a plurality of performance patterns; a performing part, performing a performance based on the performance pattern stored in the pattern storage part; an input part, inputting performance information from an input device; a rhythm detection part, detecting a rhythm from the performance information inputted by the input part; an acquisition part, acquiring from among the plurality of performance patterns stored in the pattern storage part the performance pattern corresponding to the rhythm detected by the rhythm detection part; and a switching part, switching the performance pattern being performed by the performing part to the performance pattern acquired by the acquisition part.

The present disclosure provides a rhythm point detection method and apparatus and an electronic device, and relates to the technical field of music analysis. The method includes that: an audio signal to be detected is acquired, and an audio feature curve is generated according to the audio signal to be detected; a music style of the audio signal to be detected is determined; a detection peak threshold and a detection frame width threshold are determined according to the music style of the audio signal to be detected; and a rhythm point of the audio feature curve is determined according to the detection peak threshold and the detection frame width threshold.

A content selection system and method for identifying and organizing moods in content using objectively measured scores for rhythm, texture and pitch (RTP) and clustered into six mood classifications based on an objective analysis of the measured scores. Digitized representations of the content may also be identified and organized based on the content's frequency data, three-dimensional shapes derived from the digitized representations, and colors derived from the frequency data. Each piece of content may be identified by at least a mood shape, but may also be identified by a mood color and/or a mood based on the clustered RTP scores and/or the digitized representation. Users of the selection system may be able to view the moods identified in the different manners, or combinations of two or three mood identifying manners and select and organize content based on the identified moods.

A haptic device according to one embodiment can comprise: a database unit for storing acoustic information or receiving the acoustic information from an external device; a control unit for converting the acoustic information into an electrical signal according to a predetermined pattern; a driving unit for generating a motion signal on the basis of the electrical signal; and a transfer unit for transferring a patterned tactile signal to a user by means of the motion signal.

The present disclosure relates to methods and devices for generating drum patterns. In one embodiment a method includes receiving a user generated input including a plurality of events during a time interval, and detecting the events. The method also includes analyzing the events to define a rhythmic pattern based on number of events detected, placement of each event in the time interval, and duration of the time interval. Each of the plurality of events may be classified into at least one type of drum pattern element and a drum pattern may be generated based on the rhythmic pattern to include a drum element for each event of the rhythmic pattern. In certain embodiments, pitch or tone of the events may be determined to classify events as components of a drum pattern. Processes and devices allow for professional sounding drum patterns to be output based on received input.

A method of generating a musical score file for one or more target musical instruments with a score generation component based on input audio data. The score generation component finds candidate musical notes within the input audio data using a frequency analysis to identify segments that share substantially the same audio frequency, and finds a best match for those candidate musical notes in audio data associated with target musical instruments in a sound database. A generated musical score file can be printed as sheet music or audibly played back over speakers.

A sound signal processing method according to an embodiment includes a step of acquiring an input sound signal, a step of acquiring a beat number per unit time period from the input sound signal, a step of normalizing the input sound signal with the beat number per unit time period, a step of calculating a beat spectrum of the normalized input sound signal, and a step of calculating a rhythm similarity between the beat spectrum of the normalized input sound signal and a normalized beat spectrum calculated from a reference sound signal.
