摘要
For use in a synthesizer having a wave source that produces a periodic wave, frequency shifting circuitry (364) for frequency-shifting the periodic wave and waveshaping circuitry (370) for transforming the periodic wave into a waveform containing a formant, the frequency-shifting causing displacement of the formant, a circuit for, and method of, compensating for the displacement and a synthesizer employing the circuit or the method. In one embodiment, the circuit includes bias circuitry (366), coupled to the wave source (362) and the frequency shifting circuitry (364), that introduces a bias into the periodic wave based on a degree to which the frequency shifting circuitry frequency shifts the periodic wave, the bias reducing a degree to which the formant is correspondingly frequency-shifted.
