Each of the resonance tone generation circuits 30(n) has a resonance circuit 40(n) which has a plurality of resonance frequencies corresponding to the assigned key number n, and generates a musical tone signal indicative of the resonance tone imitating the tone of the string of the piano resonated by the musical sound of the piano indicated by the retrieved musical tone signal, and a panning setting circuit 50(n) which generates a plurality of musical tone signals which are to be supplied to the plurality of output portions, respectively, and each of which indicates a different resonance tone in which a tone volume of the resonance tone indicated by the musical tone signal generated by the resonance circuit 40(n) is changed in accordance with the assigned key number, and supplies the generated musical tone signals to the plurality of output portions, respectively.

    摘要: A circuit, method, and system for producing artificial ambience effect for an input audio signal, mono, stereo, or surround. The ambience effect enhances artificial reverberation, replaces artificial reverberation, or synthesizes extra audio channels, such as surround channels. The circuit may include a transient reduction module and a reverberation filter. The transient reduction module may be adapted to reduce transients in an input audio signal of one or more channels. The reverberation filter maybe adapted to receive a transient-reduced signal of one or more channels corresponding to the transient-reduced signal.

    摘要: Provided are a memory device and waveform data editing method and editing program thereof. Waveform data obtained by sampling a musical sound is acquired, and a difference between a harmonic frequency of an nth harmonic of the waveform data and a resonance sound frequency of the nth harmonic sound of a resonance sound generation circuit is calculated, and if the difference is 1 Hz or more, a waveform of a frequency component of 20 Hz centered on a central of the frequency of the nth harmonic of a frequency spectrum is clipped. The difference calculated in regard to the clipped waveform is reduced. The waveform and the clipped original waveform are combined to edit the waveform data. Thus, in the waveform data, the difference between the harmonic frequencies of the resonance characteristic is eliminated, and resonance is facilitated and occurrence of beat of the sound is prevented.

    摘要: Decorrelation filter parameters for audio data may be based, at least in part, on audio characteristics such as tonality information and/or transient information. Determining the audio characteristics may involve receiving explicit audio characteristics with the audio data and/or determining audio characteristics based on one or more attributes of the audio data. The decorrelation filter parameters may include dithering parameters and/or randomly selected pole locations for at least one pole of an all-pass filter. The dithering parameters and/or pole locations may involve a maximum stride value for pole movement. In some examples, the maximum stride value may be substantially zero for highly tonal signals of the audio data. The dithering parameters and/or pole locations may be bounded by constraint areas within which pole movements are constrained. The constraint areas may or may not be fixed. In some implementations, different channels of the audio data may share the same constraint areas.

    摘要: A method for synthesis of an advanced hysteresis function of a plurality of inputs providing cross-feedback-controlled hysteron synthesized hysteresis networks for signal processing, controllers, music, and computer simulations in physics, engineering, and economics is described. The method includes receiving and processing of a plurality of input signals with at least two parameterized multivariable nonlinearities, each parameterized multivariable nonlinearity serving as a parameterized hysteron, to produce at least one associated output signal. The output signals are processed by controller functions, each controller function comprising memory and producing at least one control signal responsive to at least one of the output signals and for controlling an associated parameterized hysteron. The resulting system provides a hysteretic response to at least one of the plurality of input signals, and can be used in the modeling and nonlinear control of systems involving networks of gears, electrical transformers, economic processes, or other networked hysteretic elements.
