Calculation is performed for sound paths--along which sounds emitted from a sound emitting pointin an acoustic spaceare reflected and delivered to a sound receiving point. By the calculation, entering angles eR, eRby which the sound paths enter the front sideof the sound receiving pointare obtained. Calculation is then performed to obtain angles by which respective speakersC,L,R,SR,SL of a 5.1 surround system are arranged in a listening room, with the front sideof the sound receiving pointcentered 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 spacein which the sound emitting pointfor emitting sounds and the sound receiving pointfor receiving the sounds are placed.

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 &ldquo;realistic feeling&rdquo; 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.

Musical sound modification apparatus and method

Physical model tone generator, which includes a loop section with a signal delay element, generates a driving signal by modifying a loop output signal from the loop in accordance with a performance parameter such as a bowing velocity, and introduces the generated driving signal to the loop. This way, the tone generator generates a tone signal with a characteristic controlled by the performance parameter, in a pitch period corresponding to a time delay of the loop. To generate the driving signal, a nonlinear conversion section performs a nonlinear conversion on an input signal based on the loop output signal and performance parameter. The conversion section switches an input-output characteristic, to be used for converting the input signal, into one of at least first and second input-output characteristics in accordance with intensity of a signal based on the loop output signal or the input signal, so that a desired nonlinear conversion characteristic is achieved. Control section restrains a period, in which the first input-output characteristic shifts to the second input-output characteristic, from becoming shorter than the pitch period of a tone based on the loop output signal. This arrangement can prevent the shift from the first input-output characteristic to the second input-output characteristic from taking place frequently within a single period of the tone pitch and thereby avoid a high-order vibration mode.
