Problems solved by technology

[0002] With the advent of the era of mobile commerce, there has always been a demand for hand-held electronic devices that are short, thin, and fully functional, and that can be carried by users anytime and anywhere (such as electronic dictionaries, personal digital assistants, portable computers, mobile phones, electronic devices, etc.) Dictionaries, etc.) personal mobile products have also been constantly innovating, and are loved and used by more and more people in the market. The reason for this is that these products are thin, light and small. Although their performance is not as powerful as desktop computers, they can meet some of the needs of users. For example, the emergence of electronic dictionaries will solve The inconvenience and cumbersome problem of looking through the dictionary
[0003] However, these hand-held electronic devices are light, thin and short, so the computing speed and storage capacity must be sacrificed in product design, and their scalability is difficult.

Embodiment Construction

[0023] On the basis of a scale, on the stave, according to the high and low ranks of several tones, until the higher octave, it becomes the so-called scale. In each octave range, it contains five whole tones and two semitones, the so-called "diatonic scale", that is, twelve semitones are included in each octave.

[0024] The height of the musical scale has a specific frequency. According to the current general temperament standard, the A4 standard tone (that is, the scale of La) in the scale where the central C4 (Do) is defined is 440Hz. This frequency defines the frequency of other scales. . The relationship is that for the same scale, if the octave is raised, the audio frequency will be doubled, and if the octave is lowered, the audio frequency will be halved; each scale in the same octave is divided according to the ratio. Going up a half step, the frequency goes up 21 / 12. Therefore, the audio frequency of each scale of the central scale is 262Hz for Do(C4), 394Hz for Re(...

Abstract

The musical scale generating method in music synthesis is to utilize the waveform data to synthesize different scales. The frequencies of one basic scale and one synthetic scale are first obtained; the ratio between the frequencies of one basic scale and one synthetic scale is then calculated to establish one frequency ratio table; one sampling frequency is utilized to sample the basic scale to produce at least one specimen point; and finally the specimen point number of the synthetic scale is calculated based on frequency ratio table and the specimen point number to complete the synthesis of the scale.

Description

technical field [0001] The present invention relates to a music synthesis scale generation method, in particular to a scale generation method for re-sampling the same scale frequency with different sampling periods to generate different scale frequencies. Background technique [0002] With the advent of the era of mobile commerce, there has always been a demand for hand-held electronic devices that are short, thin, and fully functional, and that can be carried by users anytime and anywhere (such as electronic dictionaries, personal digital assistants, portable computers, mobile phones, electronic devices, etc.) Dictionaries, etc.) personal mobile products have also been constantly innovating, and are loved and used by more and more people in the market. The reason for this is that these products are thin, light and small. Although their performance is not as powerful as desktop computers, they can meet some of the needs of users. For example, the emergence of electronic dict...
