Abstract
The programming word controller that a kind of sound is synthetic, in a kind of simple low cost mode, in the sound synthesizer of single-chip, produce the effect of various sound and especial sound effectively, the special-effect of sound comprises synthetic method, the frequency of sound and other effects of voice.Utilize the control table of batch processing word, the built-up sequence and the association attributes of voice data are arranged in regular turn, and it is divided into data word and attribute word according to the difference of decoded positions, when the decoding operation circuit is read the attribute word, decode control signal, control sound synthesizer this data word of decoding, compositor synthesizes this data word according to present attribute, finishes the sound combination and variation.
Description
The invention relates to the synthetic programming word controller of a kind of sound, it utilizes the control table of one group of sound combinator, the order and the association attributes thereof of sound combination are arranged in regular turn, and come numeric data code and attribute code respectively by the mode of decoding, finish the sound combination and variation, can save memory and cost in a large number.
In traditional sound building-up process, need be divided into different section (SECTION) or word (Word) to sound according to it, below be referred to as word.For example, have two sentences as follows:
" today, weather was fine; tomorrow, weather was also fine " is in order to save memory, with the part heavily covered omit only store " the present ", " my god ", " gas ", " fine ", " bright ", " also " six words, " the present " is word 1, " my god " be word 2, " gas " is word 3, " fine " is word 4, and " bright " is word 5, and " also " is word 6, when synthetic this sentence, it is as follows to set up a synthetic word control table:
According to this synthetic word control table, be blended into position B from position A order.Can obtain complete words and phrases.Principle according to this, different reference positions and end position can obtain different words and phrases.
Sound has many kinds (voice, musical sound, special sound effect) and different technique of expression (the different volume of high bass, speed, echo etc.), and the kind of these sound and technique of expression below are commonly referred to as tone quality (Attribute).Sound needs to know synthetic method (voice, musical sound or special sound effect) in synthetic process, the volume of the frequency of sound (height speed), sound and not other special-effects (as echo, judder effects or the like) are arranged.
When sound needed the variation of attribute, traditional method is to set up a corresponding attribute list (leading portion literal), and was as follows:
The as above attribute list of figure, word table can follow attribute list to come synthetic video, that is word wherein " fine " can be strengthened volume, with emphasis effect.Because in this traditional synthetic method, each word need be accompanied by a specific attribute, the attribute of most of word all is identical under many situations, and so the data accumulating that repeats has caused the waste of memory.
So, purpose of the present invention mainly is to provide simply a kind of and the synthetic programming word controller of sound cheaply, can be used to control above-mentioned various effects, make in the sound synthesizer of a single-chip, can effectively produce the effect of various sound and especial sound, and need not to use CPU, make manufacturing cost greatly fall paper.
Below will do a detailed description to the present invention.In the programming word controller that sound provided by the present invention synthesizes, utilize the control table of batch processing word, to be that the built-up sequence and the association attributes thereof of the voice data of unit arranged in regular turn with word or section, and it is divided into data word and attribute (or being called control) word according to the difference of decoded positions, finish the sound combination and variation.When decoding operation circuit when reading the attribute word, can decode control signal, control sound synthesizer this data word of decoding, and compositor synthesizes this data word according to present attribute, finishes the sound combination and variation, so can save the memory that takies.So-called program word control table (abbreviation control table) but following table represented:
When the decoding operation circuit is read the attribute word, can decode control signal, the control compositor comes the decoded data word, and compositor can synthesize this data word according to present attribute.Circuit as for this decoding control can use conventional technology, carries out decoding.In addition, aforesaid word or section are the base units of voice data, and this base unit can utilize address area or other modes to distinguish.
The explanation of decoded positions:
Decoding control table with one 6 is illustrated:
C5 C4 C3 C2 C1 C0
MSB LSB
6 representatives have 64 word locations, and below simply to be divided into two parts with position C5 as follows:
So, meaning has 32 kinds of control situations, 32 different data words, and 32 kinds of control situations can be decoded and obtain more detailed control data from C0～C4.
In this decoding control table of 6, also can be divided as follows according to C5 and C4:
So can obtain more data bit (48) but less attribute bit (16) number.The control of this kind decoding process can provide the variation of different application, need adjust the ratio of data and attribute according to it.The explanation of attribute bit:
In sound synthetic, different application has different synthetic methods, as language, musical sound, effect sound etc., in addition, the effect of the characteristic of sound such as broadcasting speed, frequency, volume, echo, the various variations of trembling, the attributive classification shown in can being summarized as follows:
(1) synthetic method: phonetic synthesis, musical sound synthesize, audio is synthetic
(2) speed: the speed speed of musical sound
(3) frequency: the height (or speed) of frequency play in language
(4) volume: the size of wave volume
(6) special-effect: echo effect, tremolo effect etc.
If according to above-mentioned attributive classification, its control of definable is as follows:
3 kinds of synthetic methods, 8 kinds of speed, 8 kinds of frequencies, 8 kinds of volumes, 4 kinds of effects, and normal condition (Normal or Reset) have then just had 32 kinds of attributes.Then the number of the position of control table can be increased as the more complicated control of needs and to get final product.It is as follows to lift a routine attribute bit decoding table:
C5 C4 C3 C2 C1 C0 function explains orally
8 kinds of SPEED of 100 S2 S1 S0 speed control (0-7)
8 kinds of FREQUENCY of 101 F2 F1 F0 frequency control (0-7)
110 V2 V1 V0 volumes control (0-7) 8 kinds of VOLUME
1110 E1 E0 effects control (0-3) 4 kinds
3 kinds of 1111 W1 W0 synthetic methods (0-2)
111111 return back to initial value design RESET
0 D4 D3 D2 D1 D0 data bit (0-31)
Claims (3)
