Field of the Invention The present invention relates to a musical tone synthesizing device which generates a signal representing a desired musical sound by adding a plurality of kinds of signals; and recording for making a computer as the musical sound synthesizing device And the recording medium that functions as a function. [Prior Art] A technology for synthesizing a desired musical sound such as a human voice or an instrument playing sound has been proposed in the past. A musical sound synthesis method using CSM (C〇mP〇site Sinusoidal Modelmg: Synthetic Sinusoidal Model) (hereinafter referred to as "(:3]^tone synthesis method") is one of the methods widely used in such techniques (refer to, for example, Patent Document 1). According to this method, the wave height value yt indicating a signal of a desired musical sound (hereinafter referred to as "synthesized sound signal") is expressed as the following equation (1), and is a sum of complex sine waves having different angular frequencies and amplitudes. + ansin ω nt (1) :)" and t" are the number of chords (ie CSM times yt - alsin&) lt + a2sin6J 2t+..... Eight again: in the above formula (1) '"ai (1 is an integer that satisfies kgn)" and "ωι are the amplitude and angular frequency of the first sine wave, respectively, and the integer "'η" indicates a positive number to be added).

Fig. 7 is a diagram showing the I ghost diagram of the device using the CSM method and the device of your music. As shown in the figure, this musical tone synthesizing ~ heart # 战衣置 has a musical tone synthesizing section 70, and the device 80 is made. Among them, the musical composition 〇 has η (here η = 4) _ sine wave output unit 71 (71_1, 71-2, 7 chord oil and 仏山' and 71-4), which are generated separately, Outputter; adder 72, 铪ψ 认 + recognition, plus sine wave output unit 7-1, output output signal is added and output η 'and envelop processing -

〇: ', 87\879l5.D〇C 1254276 73, which is enclosed by the letter, the claw, and the symbol outputted by the adder 72, and is output as a synthesized sound signal S. Each sine wave, 3:5 early 兀> 7 1 includes: a sine wave generator 71a, which produces a sine wave indicating the angle ^, Dan shoulder; and the amplitude value of the multiplication factor for the sine wave multiplication indication By. On the other hand, the control device 80 shown in Fig. 7 is for the sine wave generator 71a and the multiplier 71b of each sine wave output unit η, respectively, and the angular frequency and amplitude of the music content to be synthesized are not in accordance with the time. The value is determined by the encapsulation processing unit 73 for indicating the length of time (pitch) of the synthesizing sound pitch (hereinafter referred to as "pitch period" K. In this configuration, as shown in Figs. 8 (4) to (4), four sine wave generators are shown. ^ At the same time as the arrival of the pitch period T, the sine wave starts to be generated at the same time. That is, the phase of each sine wave at the beginning of the pitch period is "〇" in all the chord generators. The envelope processing unit 73 adds the signal of the sine wave multiplication amplitude value (hereinafter referred to as "original signal") to the operator (Fig. 8 (4)), and the envelope having the interval period of the pitch period (Fig. 8 (9) To obtain the synthesized sound signal s of the waveform shown in Fig. 8(g). Fig. 9(4) and (8) respectively show the waveform and the spectrum of the synthesized sound signal S. That is, in Fig. 9(a), the horizontal axis Indicates time, the vertical axis represents signal strength. Also, in Figure (10)), the horizontal axis represents In the meantime, the vertical axis indicates the frequency 'color shading indicates the signal intensity distribution. [Patent Document 1] Japanese Laid-Open Patent Publication No. Hei No. Hei 1 1-23 No. 875 (Specially, page 3 and FIG. 1 [Summary of the Invention] However, as shown in FIG. 9 (a) ), the synthesized sound signal S-based signal intensity obtained under the configuration shown in FIG. 7 is directed to one side based on the level "〇" (herein

Moreover, according to such a signal, the sound system has a problem of becoming a harsh sound containing noise. In addition, > σ can also apply various filtering treatments to the synthesis :::: 为了 in order to suppress signal intensity bias or noise components. However, at this time, in addition to the configuration in order to obtain the composition of the ts, it is necessary to additionally provide a filter or a wave filter, which may cause a complication of increase or composition in the ground. The present invention has been made in view of such a problem, and the object of the present invention is to synthesize a natural musical tone and a wide variety of recording media by a simple configuration, which is recorded in order to make the computer function as a musical tone synthesis. Functional programmer. =: The synthesized sound signal s obtained by the configuration shown in Fig. 7 is biased toward the side by the d-degree U-level "〇" as a reference, and contains noise near the beginning of the pitch period. The inventors of the present application have reached the following discretion, i.e., one of the reasons why the synthesized sound signal S becomes a signal having such a property is that all the original signals immediately increase at the same time after the start of the pitch period. That is, since all the original signals start at the same time at the beginning of the pitch period, the waveform of the synthesized sound signal changes heartily and unsuccessfully at the point of the boundary time of each pitch period.

Fig. 2 is a block diagram showing the structure of the tone synthesizing unit 4's one by one. It is shown that the music synthesizing unit 4〇 is right 葙|code” has a number of original number 4 wheel-out units 41 (41-1, 41-2, 41-3, and 41-4), and adds a cry "a, σσ 2 And the encapsulation processing unit 43. In the CSM tone synthesis method, the original signal output list corresponding to the number of the target signals (i.e., the number of CSMs) is set. However, in the present embodiment, the setting 4 is assumed. The condition of the original signal output unit 41. In addition, in the following, in the case where the original signal output unit 4 is distinguished from each other, the variable 丨 is used as the "original signal output unit 4M".

Each of the original signal output units 41 has a signal generator: ... and a multiplier 41b. Among them, the signal generator outputs a signal of a quasi-periodic variation (hereinafter referred to as "periodic signal") Sa. The signal generator 4_ of each of the present modes has a function of selectively generating a sine wave, a triangular wave, and a rectangle, and a signal of a plurality of types having different wave patterns, as the periodic signal Sa. In this case, the signal generator 41a has a memory, which is pre-recorded with a cycle number indicating various types of signals: waveform waveform data. Further, by causing the waveform of the waveform data indicating either one to be continuous in time series, a signal having a characteristic waveform is generated. Second, the multiplier 41b multiplies the amplitude value by the period 输出 outputted by the signal generator 4ia, and outputs it as the original signal Sb. Addition = 42 adds the original signal output from the four original signal output units 41 to 丄 c Sc. The encapsulation processing unit 43 is a means for arbitrarily outputting the amplitude value of 爹s &lt; That is, the encapsulation processing unit 43 is provided with a time change of the envelope generator value/generating the table amplitude 42. The envelope is generated by the envelope outputted by the addition cry 42 to take the left mouth. It is output as a synthesized sound signal Sd. <B: Operation of the implementation type> If the user inputs the operation device 3G to the fourth operation by the rotation of the device 3G, the control device executes the sequence in order to record the recording device 20. In the following, ~ "曰口 &amp;" is entered into the RAM, and the following is accompanied by the music synthesis Su 4/tone synthesis operation. The use of the card (3) into the private implementation of the user is based on the music. Before the start, the input device 30 performs

Right to detect this operation 'Control device 1〇 will indicate the negative signal of the selected signal ( The following is called ", by;; 1% / skin shape to choose the shell material") Ds, for each original signal two mornings wide 1 full generator ... and output. On the other hand, each signal is generated by the waveform selection data, and the signal generated by the signal generator 4 is specified. Further, at any point in the synthesis of the musical tone, the periodic signal output by the k5 tiger generator 41a can be selected and used. Whenever the operation indicates that the selected signal type waveform selection data Ds is slaved (four), the output is output to each of the signal generators 41a, and the periodic signal to be outputted by the #(四)2 4 la is specified. On the other hand, when the user performs a specific operation on the input device 30 and sub-gives the start instruction of the tone synthesis, the control device 1 gives an instruction to start the generation of the signal for each signal 41 a. Further, the control means (7) calculates the frame parameters in accordance with the contents of the music to be synthesized, and outputs them to the tone synthesis = 4 在 in each period having a predetermined length of time (e.g., 5 to 3 degrees). As shown in Figure 2, the frame parameters include angular frequencies such as 丨, &amp; 2, μ and ω4), initial phase *ρι(ρ1, p2, pup4), amplitude values, u, a3, and a4) and the pitch period T. . It is stated that the pitch period T is the time according to the pitch of the music to be synthesized [and is supplied to the envelope 43. Further, the angular frequency and the initial phase Ρ1 are supplied to the signal generator 41a of each of the original signal wheeling units 41. That is, the signal generator 4ia of the original signal output unit 41-1 indicates the angular frequency ω 1 and the initial phase pl, and the signal generator 41a of the original signal output unit 41_2 indicates the angular frequency ω 2 and the initial phase p2. The angular frequency 〇 i is a periodic signal which the signal generator 41a of the original signal output unit 4M should output.

Further, the angular frequency of the signal generator 41a given to the original signal output unit is the smallest, and the secret value becomes larger as the sum, the household, the e 4, t, and the original signal output unit. On the other hand, the initial phase ρι indicates the phase of the period at which the period signal to be output by the original signal output unit number generator 41a starts at the middle interval period. Further, the amplitude value is an adder value applied to the signal generator, and the amplitude value of the output signal is multiplied for the multiplication of each of the original signal wheeling units 41. For example, the multiplier 4 (10) for the original signal take-off unit 41] shows the amplitude value a1, and the original signal output unit 仏 41b indicates the amplitude value a2. The wood is generally the material of the spacing (4). The value of the tone is reflected in the synthesized sound. Here, in Fig. 3 (4), the supply of the yeast number is indicated by the downward arrow. If the point at which the pitch period τ starts is reached: ; :=M. The parameters of the building just supplied are reflected in the synthesized sound. That is, the timing parameters of the sequence shown in =, (4) are only the time interval ratios of the composite audio supply frame parameters, and the Taguchi (4) system. However, the length of time for the supply of the number of the ducks is pre-determined -: / interval between the two is according to the length of the music should be synthesized. The % length of 疋 may also be longer than the interval period τ. Output: face 41: the output of the parameter is paralleled by the control device 10; the original signal is output; 4r is output according to the original signal of the parameter. That is, each = signal generator of the output unit 41 is:

The signal of the type specified by Ds will be selected as the periodical letter of the angular frequency (1) of the w. The output of this periodic signal Sa is tied to each

After the shoulder-calculation, as the original signal: the present embodiment 'indicates to the four original signal output units 41, the angular frequency (7) is smaller, * 曰 not 41 ^, the number of the original signal output unit 4M and (The following is only called "the odd number of original signal output units""

The values of Pi and P3 are set to "〇". In the phase unit 41, the angle is: from this, the heart is shown to the four original signal output elements 41 2 and 41 4 / the even number of the original signal output is a few buckets W and 41-4 (the following is only avoided ~ 彳 平 、, &quot; 冉 偶 偶 原 原 原 原 原 仞 仞 仞 仞 仞 相位 相位 相位 相位 相位 相位 相位 相位 相位 相位 相位 相位 相位 相位 相位 相位 相位 相位 相位 相位 相位 相位 相位 相位 相位 相位 相位 相位 相位 相位 相位 相位 相位 相位 相位 相位 相位 相位(4) Timing diagram of the transformation.

O:\87\879I5.DOC ' 15- 1254276 is added by the adder 42' and supplied as a signal Sc to the encapsulation process crying... The encapsulation processor 43 is the envelope generated by the encapsulation generator :: (10) Multiply, and the signal thus obtained is output as a synthesized sound signal. Here, the encapsulation generator 43a generates a one-way, which has a length of time which is the same as the period T from the control device as the frame number. Further, the speaker 50 rotates the synthesized sound based on the synthesized sound signal rotated by the encapsulation processing unit 43. Thus, in the present embodiment, the original signal 轮 rotated by one of the four original signal rotation units (the original signal output unit 41_1Λ41_3) is increased immediately after the start of the pitch period, and on the other hand, other original signals. The original signal from the origin, output single U-2 and 41_4) is less immediately after the start of the spacing (four). In other words, all events in which the original signal is simultaneously increased (or decreased) immediately after the start of the pitch period are avoided. As a result, according to the present embodiment, the natural synthesized sound of the noise at the start of the amplitude value of the 强度g 5 tiger intensity or the start of the pitch period can be suppressed as shown in Fig. 9 . In this regard, it is described in detail with reference to FIG. Here, FIG. 5(a) is a graph showing the waveform of the synthesized sound signal ^ outputted by the encapsulation processing unit 43. Figure 5(b) is a spectrum of this signal. In Figure 5 (hook, ° horizontal axis does not time 'the vertical axis represents the signal strength. Another aspect, in the figure), the horizontal axis table is not punctual, the vertical axis represents the frequency, and the color shading indicates the distribution of the signal intensity (bright Part indicates that the signal strength is large). Comparing Fig. 5 (4) with Fig. 9 (4), in the present embodiment, the signal intensity is equally divided between the ";" side and the "-" side based on the level "0". This is because the original signal Sb outputted by the odd-numbered original output unit 4 1 immediately increases the signal strength bias toward the "+" side after the start of the pitch period, and is caused by the even number.

O:\87\87915 D〇C -16- 1254276 The original signal is turned on and the original signal Sb is output. The original signal Sb output immediately after the start of the interval period is offset by the signal strength bias on the "-" side. Further, as shown in Fig. 5 (b), the synthesized sound of the present embodiment is obtained as compared with the conventional synthesized sound signal s which is not comparable to that of Fig. 9(b). No. Sd "The high-frequency component (noise) at the beginning of the pitch period is reduced. This is like a waveform in which the graph of Fig. 5(a) is enlarged in the time axis direction becomes s L唬, and the waveform becomes continuous at the beginning of the pitch period. Understand this. In this way, according to the Taihui & Marriage, the yoke of the yoke can be obtained as shown in Figure 9, to obtain the amplitude of the amplitude of the slogan intensity or the noise of the rain or the beginning of the pitch period. Naturally synthesized sound, and it is not clouded, and it is not necessary to suppress the signal intensity bias or the filtering process of the noise at the beginning of the pitch period. Further, in the present embodiment, any one of the plurality of types of signals having different waveforms is selected - The person's output as a periodic signal~, so that the sound quality (especially the timbre) of the synthesized sound can be obtained as a result of the singularity. Moreover, the user selects any of the plural type signals by the user. Therefore, the synthesized sound having the sound quality of the user's preference can be obtained. <C: Modifications> The above description (4) is merely an example, and various changes can be made without departing from the scope of the present invention. For example, the following description can be specifically modified. <C-1: Modification 1> The above embodiment is an example in which the initial phase i is "p U" or "π", but the initial phase P1 is The value is not limited to this. That is, the initial phase ?1 value should be appropriately selected so that the original signal outputted by the odd-numbered original signal output unit 41 is increased immediately after the start of the pitch period by the signal O:\87\ 87915 DOC -17- 1254276 Strength bias, and the signal intensity due to the first side is equal to the original signal. Immediately after the start of the interval period, the round-off unit 41 is biased against the lock, signal strength The two sides of the level, and the phase of the original signal of the above-mentioned embodiment, but at the beginning of each point at the beginning of the pitch period, all of the original signals can be used as follows in the interval period. The constitution of the constitution is not limited to this. For example, it is not a constitution to replace this structure. (1) The aspect 1 41 may also be a symbol for constituting the amplitude value of the odd-numbered original signal output unit 41, the disk index is dry-filled, and the number of the original signal output units 4 i and the field are The sign of the value is different. For example: Figure 2 and . The symbol is "+, the composition of the other * jin" amplitude value a 唬 唬 is +", on the other hand, the amplitude value of the heart and the "-". In this configuration, the phase difference between the odd-numbered original signal output unit = original # and the even-numbered original signal output unit is only shifted by 4", so that the waveforms of the original signals are the same as those of the original signal. Waveform shown in 3(8). Therefore, the same effects as the above embodiment can be obtained. (2) The aspect 2 may be a configuration in which the signals output from the multiplier 41b of the odd-numbered original signal output units 41 of the four original signal output units 41 and the even-numbered original signal output units 41 are used. The signals output from the multiplier 41b are multiplied by the envelopes having different signs, and are output as the original signals. That is, as shown in Fig. 6, the encapsulation processing unit 41c is provided for each of the four original signal output units 41, which multiplies the envelope indicated by the control device 1 to the multiplier from the O:\87\87915 The output signal of .DOC -18-1254276. Specifically, in the odd-numbered - encapsulation processing unit 41c, the interval period I is outputted by two: -there is a decrease in r: and the end of the period is two. Process 2: The gate is in the even number of original signal rotation units... The seal is used by the beginning of the pitch period at "4 continues to increase, and at the end of the interval period, the point reaches "0"". Therefore, the odd number of original signals Output unit"匕f. Immediately after the start of the cycle, the original signal of the other is in the interval. The original signal of the original number of the original errone is output. The output of the tiger is also reduced immediately after the start of the avoidance. Since the original k 立 is in a state after the start of the pitch period, the same effect as the above embodiment can be obtained. "Additionally, in the present invention, as long as the original signal is in the plural,
