According to one aspect of the present invention, an electronic musical instrument generates a string tone signal output from one of the left and right channels based on an input excitation signal corresponding to a specified pitch, and generates a string tone signal output from the other of the left and right channels based on an accumulated signal obtained by accumulating the outputs of the first closed-loop circuit (36A-39A), the second closed-loop circuit (36B-39B), and the third closed-loop circuit (36D-39D) arranged corresponding to the pitch.

This invention relates to the field of music education technology, specifically to a musical instrument playing training system and method based on real-time pitch monitoring. The system includes a musical instrument acoustic waveform analysis module, a tuning frequency tracking module, a pitch deviation analysis module, a muscle memory reshaping guidance module, and a musical instrument mastery blind spot positioning module. In this invention, by sensing the vibration envelope and reconstructing the energy distribution of the overtone series, the core musical tone components are accurately extracted from a complex acoustic environment, improving the accuracy of fundamental frequency identification and enhancing the ability to capture microscopic pitch drift. This effectively solves the problem of poor anti-interference in traditional detection methods, transforming pitch deviation into a concrete physiological cause analysis, optimizing the depth of performance mechanism analysis and enhancing the physical correction directionality. It achieves precise integration of correction actions and performance rhythm, ensuring the scientific nature of muscle memory reshaping and significantly reducing functional pitch deviation. By tracking the rate of movement deformation and tracing the source of technical bottlenecks, it optimizes musical instrument mastery and improves the level of intelligent music training.

A musical tone signal generation apparatus, method, and storage medium that utilizes an all-pass filter for efficient processing. The method involves setting a first delay unit that generates a delay corresponding to a specified pitch, setting its pre-stage delay unit as a 0th delay unit, and its post-stage delay unit as a 2nd delay unit. At least three fractional delay blocks are connected to the first, 0th, and 2nd delay units, respectively. In a scenario where, based on a change in the specified pitch, one of the 0th and 2nd delay units is set as a new first delay unit, and the pre-stage delay unit of the new first delay unit is set as a new 0th delay unit, and the post-stage delay unit of the new first delay unit is set as a new 2nd delay unit, one of the 0th and 2nd delay units continues to be connected to the fractional delay blocks, and at least one of the new 0th and new 2nd delay units is then changed to be connected to at least one of the fractional delay blocks other than the fractional delay block connected to the new first delay unit.

The application relates to an audio processing method, device and electronic equipment. The method comprises: performing audio repair by using an audio repair strategy based on an audio type of a target audio frame; wherein the target audio frame is determined according to frame types of a current audio frame and a previous audio frame; the frame types comprise normal audio frames, packet loss audio frames and repaired audio frames; the audio types comprise human voice clear tone, human voice turbidity and music tone; the audio repair strategy is used to generate repair frame data according to the audio type of the target audio frame; and the repair frame data is used to replace audio frames or data fusion. The application can improve the continuity of repaired audio, thereby improving the auditory experience of a user.

To provide an electronic wind instrument, a pitch switching method, and a pitch switching program that enable easy switching to musical tones based on different pitches simply by adjusting the breath of the performer to the first and second mouthpieces. [Solution] When the intensity index value Vr, which corresponds to the first exhalation intensity V1 based on the air velocity of the exhaled air blown into the upper inlet 310 and the second exhalation intensity V2 based on the air velocity of the exhaled air blown into the lower inlet 311 located adjacent to the upper inlet 310, is greater than or equal to the first pitch change threshold Tcrd, the sound production of a musical tone based on a different pitch that is one octave higher than the key pitch is initiated. This makes it easy to switch to a musical tone based on a different pitch by adjusting the air velocity of the exhaled air blown into the upper inlet 310 and the lower inlet 311 by the performer, similar to how it is done with actual wind instruments such as a flute.

A controller that controls a musical sound generation device has an acquisition unit that acquires gaze information of a user, a display control unit that displays a plurality of operating portions associated with control commands of the musical sound generation device on a display unit, and displays a pointer for selecting the operating portion on the display unit based on the gaze information acquired by the acquisition unit, a determination unit that determines selection of an operating portion overlapping at least a part of the pointer among the plurality of operating portions, and a communication unit that transmits, to the musical sound generation device, information conforming to a MIDI standard corresponding to the operating portion of which the selection has been determined by the determination unit.
