摘要： A vocoder system for improving the performance expression of an output sound while lightening the computational load. The system includes formant detection means and division means in which the center frequencies have been fixed. The modulation level with which the levels of each of the frequency bands that have been divided in the division means are set by a setting means based on the levels of each of the frequency bands that correspond to those that have been detected in the formant detection means and formant information with which the formants are changed. Therefore, it is possible to improve the performance expression of the output sound with a light computational load and without the need to calculate and change the filter figure of each filter for each sample in order to change the center frequency and bandwidth of each of the filters comprising the division means.

摘要： The content of component waveforms of at least one signal is changed in a variety of ways among the formant center signals that are synthesized with the formant waveform signals, making it possible to arbitrarily change the waveform of a musical tone that is generated. To cope with changes in the formant waveform signals Ffj(t) or the formant carrier signals Gj(t) formed by synthesizing the component waveforms, furthermore, the signals Fj(t) and Gj(t) are weighed and interpolated. This permits the signals Fj(t) and Gj(t) to change smoothly. Moreover, the number or combination of formant waveform signals synthesized to produce a musical tone is controlled depending upon the musical factors, elapsed time of sounding, envelope levels, envelope phases and/or settings instructed by an operator. This enables the form of the synthesized formant to be changed and the content of a musical tone that is generated to he changed in a variety of ways.

摘要： An electronic music system which imitates acoustic instruments addresses the problem wherein the audio spectrum of a a recorded note is entirely shifted in pitch by transposition. The consequence of this is that unnatural formant shifts occur, resulting in the phenomenon known in the industry as "munchkinization." The present invention eliminates munchkinization, thus allowing a substantially wider transposition range for a single recording. Also, the present invention allows even shorter recordings to be used for still further memory improvements. An analysis stage separates and stores the formant and excitation components of sounds from an instrument. On playback, either the formant component or the excitation component may be manipulated.

摘要： According to the invention, formant waveform signals which are waveforms synthesized from frequency components corresponding to formants of musical tones, are stored and read out or generated. When such formant waveform signal is read out or generated, the density of frequency components of the formant of the formant waveform signal is controlled and also the frequency of a formant center signal which is to be synthesized is a center signal with the formant waveform signal is controlled. In this way, the formant waveform signal is synthesized on the formant center signal. Thus, the density of formant frequency components and the formant center signal frequency can be controlled separately and independently. Further, the kind of formant waveform signal is switched according to musical factors of musical tone. Thus, different kinds of formant waveform signals to be output are switched according to musical factors of musical tones.

摘要： A fixed formant filter for a digital electronic instrument of the type in which musical tones are generated from waveshape data calculated independently of frequency of the tone from constituent generalized Fourier components. The Fourier components are individually scaled by scale factors selected from a set of stored scale factors which define the transfer characteristic of the fixed formant filter. Each separately addressable stored scale factor corresponds to a different frequency value in the musical scale. A scale factor is selected for separately scaling each harmonic of the tone generated in response to the particular note of the musical scale keyed on the instrument. The selected scale factors may be modified by a frequency deviation signal to provide vibrato or other frequency modulation effects. The selected scale factors are also corrected for any frequency deviation between the actual frequency of the harmonic of the keyed note being scaled and the frequency value associated with the selected scale factor.

摘要： In the production of a desired musical waveform by combining harmonic components corresponding to respective harmonic orders, each harmonic component value is controlled by a selected cut-off harmonic order qc, level Ha and slope of the formant filter characteristic. The cut-off harmonic order qc, the level Ha and the slope values can each be varied over a predetermined range. Therefore, the slope values of the formant filter characteristic are interpolated to raise resolution, by which it is possible to prevent an abrupt change in the formant filter characteristic and suppress the generation of noise.

摘要： An electronic music system (400) which imitates acoustic instruments addresses the problem wherein the audio spectrum of a recorded note is entirely shifted in pitch by transposition. The consequence of this is that unatural formant shifts occur, resulting in the phenomenon known in the industry as ''munchkinization''. The present invention eliminates munchkinization, thus allowing a substantially wider transposition range for a single recording. Also, the present invention allows even shorter recordings to be used for still further memory improvements. An analysis stage (50) separates and stores the formant and excitation components of sounds from an instrument. On playback, either the format component or the excitation component may be manipulated.
