Examples of an aiding device for singers are described. The aiding device comprises a body that has a periphery edge, a top wall and a smooth inner wall. The top wall curves away from the periphery edge thus forming a cup-like cavity which is shaped to define a first chamber and a second chamber that are interconnected together. The first chamber is shaped and sized to fit over an earlobe of a singer while the second chamber has a distal end that is designed and configured to be positioned in proximity to a user's mouth. When in use the first chamber encloses one of user's ears and the distal end of the second chamber is positioned in proximity to user's mouth with the periphery edge pressed against user's face such that a sound produced by the user is captured and travels into the second and first chamber and is reflected back from the smooth inner wall producing echo within the cavity. Thus, the unfiltered sound coming out from the singer's mouth is provided to one of the singer's ear in real time and hear the original sound or key in the other ear so that the singer can match his/her pitch to the original sound.

An apparatus and method for providing a musical instrument effects unit with transistor bias voltage visualization are disclosed. An example embodiment includes a musical instrument effects apparatus with transistor bias voltage visualization, the apparatus comprising: a transistor amplifier; a bias control coupled to the transistor amplifier to adjust an active bias voltage setting for the transistor amplifier; and a bias voltage meter coupled to the transistor amplifier to monitor, measure, and enable visualization of the active bias voltage setting, the bias voltage meter including a visualization device to produce a visual representation of the active bias voltage setting.

An information processing device 11 including: a control data generation unit that inputs analysis data X that is to be processed, to a trained model that has learnt a relationship between analysis data X that represents a time series of musical notes, and control data Y for controlling movements of an object that represents a performer, thereby generating control data Y according to the analysis data X.

An apparatus may be designed to enable a user to receive, record, display, edit, arrange, re-arrange, play, loop, extend, export and import audio and video data. The audio and video data to be organized as, for example, but not limited to, a song comprised of song parts. The song parts may be comprised of tracks, and each track may be comprised of one or more layers. The various methods and systems disclosed herein incorporate such data segmentation to enable the user to intuitively and hands-free record, arrange, and perform songs comprised of both sequential and parallel tracks. In this way, the looper may enable a musician to record and loop tracks for a song, arrange the tracks into song parts, and during the same session, transition the playback from one song part to another, all the while recording a track on top of the transitioning song parts.

A method and system for teaching oneself to learn to play a string instrument and master it by analyzing ones real-time hand/finger movement/technique/form, enabling oneself to progress and correct ones own mistakes simultaneously. In one aspect, a system for learning to play a string instrument is provided that includes a simulation instrument that includes a plurality of strings, wherein at least one of the strings includes at least one-touch sensing sensor thereon in communication with at least one processor to receive a signal from the at least one touch-sensing sensor and determine therefrom when and where on the at least one string a user applies pressure to the at least one string.

A stringed instrument tuner that senses the vibration of all the strings of the instrument independently and simultaneously via ultraviolet reflective light sensors that are immune to interference from ambient alternating-current lighting. The pitches of the strings are then measured continuously in real-time and transmitted wirelessly to a receiver that simultaneously graphically displays how far out-of-tune all of the strings are so that the musician can instantly see which strings need tuning and tune them quickly. The receiver may be a smartphone, smartwatch, smart glasses, computer, self-tuning system, or a dedicated wearable receiver-display unit.

A computer-implemented method includes obtaining a trained model trained to store a relationship between first performance information and evaluation information. The first performance information includes a plurality of performance units. The evaluation information includes a plurality of pieces of evaluation information respectively associated with the plurality of performance units. The method also includes obtaining second performance information including an evaluation of each performance unit of the plurality of performance units. The method also includes processing the second performance information using the trained model to infer the evaluation of the each performance unit.

User interface techniques provide user vocalists with mechanisms for solo audiovisual capture and for seeding subsequent performances by other users (e.g., joiners). Audiovisual capture may be against a full-length work or seed spanning much or all of a pre-existing audio (or audiovisual) work and in some cases may mix, to seed further contributions of one or more joiners, a user's captured media content for at least some portions of the audio (or audiovisual) work. A short seed or short segment may span less than all (and in some cases, much less than all) of the audio (or audiovisual) work. For example, a verse, chorus, refrain, hook or other limited “chunk” of an audio (or audiovisual) work may constitute a short seed or short segment. Computational techniques are described that allow a system to automatically identify suitable short seeds or short segments. After audiovisual capture against the short seed or short segment, a resulting, solo or group, full-length or short-form performance may be posted, livestreamed, or otherwise disseminated in a social network.

A method of determining a data output timing, performed by at least one processor in an information processing device for an electronic musical instrument includes, via the at least one processor: obtaining data of a first performance operation on the electronic musical instrument by a user; obtaining data of a second performance operation on the electronic musical instrument by the user; and determining the data output timing for outputting a data to the user based on a time interval between the first and second performance operations.

Provided is an information processing device including an acquisition unit that acquires subjective evaluation information from a second user about each performance performed by at least part of a body of a first user moving, a learning unit that performs machine learning on a relationship between the each performance and the corresponding subjective evaluation information and generates relationship information between the each performance and the corresponding subjective evaluation information, and a presentation unit that presents feedback information to the second user based on the relationship information.
