摘要： Methods and apparatus may provide for one or more of: receiving an input signal containing frequencies from among a first range; filtering the input signal to produce a first intermediate signal containing frequencies from among a second range; producing a sub-harmonic signal from the first intermediate signal containing frequencies from among a third range, the third range of frequencies being about one octave below the second range of frequencies; canceling energy at at least some frequencies from among a fourth range of frequencies from a left channel signal of the input signal to produce at least a portion of a left channel output signal; and canceling energy at at least some frequencies from among a fifth range of frequencies from a right channel signal of the input signal to produce at least a portion of a right channel output signal.

摘要： An apparatus and method for modeling an acoustic sound in an electric stringed musical instrument is provided. A preferred embodiment, among others, includes a bridge sensor configured to sensing string vibrations at the bridge of the instrument so that a bridge signal is generated in accordance with the vibrating strings. A body sensor, which may be positioned at different points on or within the body of the instrument, senses the resonance of the string vibrations. The body sensor generates a body resonance signal in accordance with the sensed resonance. An amplification circuit amplifies the body resonance signal when the amplitude of bridge signal exceeds a first predetermined level. In addition, a second amplification circuit amplifies the bridge signal. A summing circuit adds the amplified body resonance signal with the amplified bridge signal to produce an output signal that, when replicated in sound, models the sound of an acoustic instrument.

摘要： A sub-harmonic generator includes: an input filter operable to receive an input signal containing frequencies from among a first range and to produce a first intermediate signal containing frequencies from among a second range; a signal divider circuit operable to receive the first intermediate signal and to produce a square wave signal containing square wave signal components at fundamental frequencies from among a third range, the third range of frequencies being about one octave below the second range of frequencies; a wave-shaping circuit operable to receive the square wave signal and to produce a second intermediate signal containing sinusoidal signal components from among frequencies corresponding to the respective fundamental frequencies of the square wave signal components; an RMS detector operable to produce an RMS signal corresponding to an instantaneous amplitude of the first intermediate signal; and a voltage controlled amplifier operable to amplify the second intermediate signal by an amount proportional to the RMS signal to produce a sub-harmonic signal.
