The invention relates to the technical field of artificial intelligence, can be applied to the field of medical health, and discloses a timbre conversion method, device, equipment and medium based on cultural semanteme, the method comprises the following steps: constructing a cultural semantic timbre library comprising a semantic label and timbre characteristic parameter mapping relationship, the semantic label characterizing emotional semanteme of a target timbre, and the timbre characteristic parameter mapping relationship between the semantic label and the timbre characteristic parameter; the timbre characteristic parameters comprise a pitch range, rhythm rhythm and a harmonic structure; performing feature extraction based on text, image and audio multi-mode information to obtain semantic keywords, visual emotion features and audio acoustic features; performing attention weight fusion on the features through a multi-modal fusion deep learning model, and dynamically adjusting model parameters in combination with a semantic timbre library to generate a target timbre; and finally, intelligent conversion from the multi-mode information to the adaptive tone is realized. Through semantic-driven multi-modal feature collaborative optimization, the defect that timbre conversion machinery is stiff and lacks emotional expression is overcome, and the integrating degree of timbre expression and semantic scenes is improved.

The present invention aims to change contents of an automatic accompaniment in accordance with a pitch range of a key that a user plays.

The other ends of the two strings are installed at the bottom of the guitar support sequentially through the string support, the timbre and the bridge, and the bridge is arranged in the middle of the guitar cylinder. The huqin can stabilize the intonation of the huqin, is convenient for a player to press strings, is convenient for students to learn and play, can maximally reach three octaves in the range span, solves the intonation problem in the early stage of learning, enables people to play music more simply, and promotes the popularization of the huqin.

The present application discloses a pitch adjustment method and related devices, equipment, systems and media. Among them, the pitch adjustment method includes: obtaining a first audio collected by an in-vehicle sound pickup device based on a preset sound pickup area; wherein, the first audio contains a preset voice command issued by a voice interaction person in the vehicle; performing a pitch judgment on the voice interaction person based on the first audio to obtain a first sound pickup area, and obtaining a second audio collected by the in-vehicle sound pickup device based on the first sound pickup area; performing frequency domain analysis on the second audio to obtain the frequency domain distribution of the second audio; wherein, the frequency domain distribution includes: the sound frequencies of each sound source forming the second audio; in response to the frequency domain distribution satisfying a first condition, adjusting the device parameters of the in-vehicle sound pickup device to obtain an optimized sound pickup area of the in-vehicle sound pickup device. The above solution can adaptively adjust the sound pickup area.

A method includes detecting whether there is a very short pitch lag in a speech or audio signal that is shorter than a conventional minimum pitch limitation using a combination of time domain and frequency domain pitch detection techniques. The pitch detection techniques include using pitch correlations in a time domain and detecting a lack of low frequency energy in the speech or audio signal in a frequency domain. The detected very short pitch lag is coded using a pitch range from a predetermined minimum very short pitch limitation that is smaller than the conventional minimum pitch limitation.

An electronic device comprising circuitry configured to separate by audio source separation a first audio input signal into a first vocal signal and an accompaniment, and to transpose an audio output signal by a transposition value based on a pitch ratio, wherein the pitch ratio is based on comparing a first pitch range of the first vocal signal and a second pitch range of the second vocal signal.

The invention discloses a time-domain harmonic structure-based range expansion method for blowpipe musical instruments, and the method comprises the steps: carrying out the cross-family timbre similarity analysis: carrying out the cross-family similarity analysis of narrow-range high-pitch national blowpipe musical instruments, such as suona horn, Xun and the like, and copper pipe family and wooden pipe family musical instruments, wherein the wooden pipe family can be subdivided into an edge excitation family, a single reed family and a double reed family musical instrument, and an optimal mapping reference musical instrument of the target musical instrument is determined; adjusting the pitch and the length of each audio sample; extracting harmonic energy structures of sample audios of the reference musical instrument and other range musical instruments (medium, low and multiple bass) in the symphony configuration; calculating to obtain a multi-sample weighted frequency spectrum centroid and extracting a harmonic energy structure-based mapping rule group between the reference musical instrument and the family; extracting pure harmonics of the audio sample of the target narrow-range musical instrument according to frames, and adjusting the energy structure of each harmonic according to the mapping rule group extracted from the reference musical instrument; signals are reconstructed according to frames, and range expansion of the target narrow-range wind instrument is achieved.

The utility model discloses a novel bowed-string musical instrument with a bow bracket, and relates to the technical field of bowed-string musical instrument manufacturing. In order to avoid the defects and harm caused by the twisting posture of a violin and the like which are clamped by the head and the shoulder and the problems of narrow range, weak high pitch and the like of the Chinese Huqin, the Chinese Huqin is developed and formed by utilizing the advantages of wide range, strong and bright high pitch and natural and comfortable holding mode of the Huqin and the like of the violin. According to the technical scheme, a wooden panel guitar body, a guitar body side plate and a bow bracket assembly are detachably connected through bolts or buckles, the guitar body is provided with three or more strings, during playing, the guitar body is arranged on a leg in a left-inclined mode, and a bow and a guitar body panel are arranged on the bow bracket assembly in parallel. According to the utility model, Chinese and Western are combined, the manufacture is simple, the wide range of violin and strong and bright high pitch are provided, and the huqin can be played in a natural and comfortable huqin holding mode.

The present invention provides an automatic arrangement method, an automatic arrangement device, and a computer program product, which can produce arrangement data that is easy to play and has a reduced number of simultaneously sounding notes from musical piece data. The present invention determines an outer sound symbol, and the outer sound symbol is the highest in pitch among notes that have substantially the same sounding start time in a melody part obtained from the musical piece data. A melody part from which an inner sound symbol is deleted is produced, and the inner sound symbol starts to sound during the sounding period of the outer sound symbol and is low in pitch. For each pitch range in which the pitch range of one octave is staggered by one semitone, a candidate accompaniment part in which the root notes of each chord of the chord data of the musical piece data are arranged to sound at their sounding timing is produced, and an accompaniment part is selected therefrom. The arrangement data obtained from the melody part and the accompaniment part can be set as arrangement data that is easy to play and has a reduced number of simultaneously sounding notes.
