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

[0024] Based on a musical scale, the ranks of several notes arranged in order of high and low on the staff, until the high octave, become the so-called musical scale. In each octave, there are five whole tones and two semitones, which is the so-called "diatonic scale", that is, each octave contains twelve semitones.

[0025] The musical scale has a specific frequency. According to the current general music standard, the A4 standard tone (that is, the scale of La) in the scale where the central C4 (Do) is located is defined as 440 Hz. This frequency defines the frequency of other scales. . The relationship is that for the same scale, raising an octave will double the audio frequency, and a lower octave will halve the audio frequency; each scale in the same octave is divided by ratio, since there are twelve semitones in an octave, each Raise half a scale, frequency raise 2 1 / 12 . Therefore, the audio frequency of each scale of the central scale is 262Hz for Do (C4), 394Hz for Re (D4...

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 musical scale generation method for music synthesis, in particular to a musical scale generation method that resamples the same scale frequency with different sampling periods to generate different scale frequencies. Background technique [0002] With the advent of the mobile commerce era, there has always been a demand for short, thin, lightweight, fully functional, and emphasized handheld electronic devices (such as electronic dictionaries, personal digital assistants, portable computers, mobile phones, electronic Dictionaries, etc.) Personal mobile products have been constantly innovating, and they are being loved and used by more and more people in the market. However, the development of personal mobile products in the market is not satisfied and stagnant, but is trying to move towards more. The reason is that these products are light, thin and short. Although their performance is not as powerful as desktop computers, ...
