摘要： Calculation is performed for sound paths 112-1, 114-1 along which sounds emitted from a sound emitting point 104 in an acoustic space 102 are reflected and delivered to a sound receiving point 106. By the calculation, entering angles θR1, θR2 by which the sound paths enter the front side 106a of the sound receiving point 106 are obtained. Calculation is then performed to obtain angles by which respective speakers 52C, 52L, 52R, 52SR, 52SL of a 5.1 surround system are arranged in a listening room, with the front side 106a of the sound receiving point 106 centered thereon. Audio signals on the respective sound paths are distributed among channels for any two speakers. Consequently, sharp localization of sound images is achieved, requiring less calculation in simulating acoustic characteristics of the acoustic space 102 in which the sound emitting point 104 for emitting sounds and the sound receiving point 106 for receiving the sounds are placed.

摘要： The present invention is directed to a musical sound modification apparatus and method whereby natural musical instrument sounds are analyzed to extract time variant information of pitch, amplitude and timbre, as Musical Sound Modification Data, which are stored in a temporary memory area as pitch Template, amplitude Template and timbre Template for each of attack part, sustain part and release part of a musical sound. Musical Sound Modification Data for one musical note is formed by selectively joining each Template of attack part, sustain part and release part, and for each of pitch, amplitude and timbre, and is pasted to a series of musical note data in music data. At music reproduction by the music data, the generated musical sound gives a “realistic feeling” to human ear owing to supplied time variant characteristics, because each of pitch, amplitude and timbre of the musical sounds corresponding to the musical note data is modified by said Musical Sound Modification Data.

摘要： In a method of generating musical tones through a plurality of channels according to performance information by means of a processor placed in either of a working state and an idling state and a buffer connected to the processor, control information is successively produced for the plurality of the channels according to the performance information when the same is successively inputted. A regular task of the processor is periodically instituted according to the control information for successively executing a routine synthesis of waveform samples of the musical tones allotted to the plurality of the channels and for temporarily storing the waveform samples in the buffer. It is detected when the processor occasionally stays in the idling state for instituting an irregular task of the processor to execute an advance synthesis of a waveform sample of a musical tone allotted to a particular one of the channels and for reserving the waveform sample in advance. The processor is controlled to skip the routine synthesis of the waveform sample allotted to the particular channel while loading the reserved waveform sample into the buffer. The waveform samples are sequentially read out from the buffer in response to a sampling frequency to generate the musical tones through the plurality of the channels.

摘要： A musical tone synthesizing apparatus at least comprises two loop circuits. Each loop circuit delays an input signal thereof by a delay time corresponding to a tone-pitch period of a musical tone to be produced while circulating the input signal therethrough. When the loop circuits are connected in series, an excitation signal is applied to one loop circuit, while an output signal of one loop circuit is supplied to another loop circuit. Then, the excitation signal is mixed together with the output signals of the loop circuits, so that a musical tone signal representing a synthesized musical tone is generated. The excitation signal is generated by mixing a noise signal and a musical-tone-waveform signal. When simulating the violin sounds, the noise signal is made based on a frictional sound which is caused due to a friction between a string and a bow. Incidentally, a filter can be provided to perform a filtering operation on each of the excitation signal and the output signals of the loop circuits. Further, an overflow detecting circuit can be provided to detect an overflow event in which a signal level of the signal circulating through each loop circuit exceeds a predetermined limit value representing the maximum value of the digital data, used in the apparatus, whose number of bits is determined in advance. When the overflow event is detected, an input level of each loop circuit is automatically adjusted. incidentally, the signal level can be visually indicated by indicators such as LEDs.

摘要： An electronic musical instrument: is provided to perform an active control on the pitch of the musical tone to be generated, thereby simulating the pitch-rising phenomenon to be occurred in the performance of a non-electronic musical instrument such as a wind instrument, percussion instrument and stringed instrument. In case of the simulation of the wind instrument, this electronic musical instrument is mainly configured by an excitation-vibration circuit and a tube simulation circuit which are connected together by means of a junction. The tube simulation circuit is configured by a closed-loop circuit in which plural delay circuits and junction circuits are connected together in cascade-connection manner. Herein, the delay circuits simulate the propagation delay of the air-pressure wave to be transmitted through the tube of the wind instrument, while the junction circuits simulate the scattering manner of the air-pressure wave at the points at which the diameter of the tube is changed. The number of the delay stages which are required to simulate the musical sound is controlled to be changed in a lapse of time.
