Frequency Modulation and Decay Frequency modulation by an arbitrary function is not possible. ... After the FFT, the sequence is circularly shifted by N/2 to locate the peak at the center. ... The correct values are calculated by double-precision arithmetic. ... (fm - 20 ) note that the spectrum distribution become wider and the phase has a quadratic curve shape. ... We have designed this procedure to the case of music synthesis, but it can also be applied to many acoustical and otheranbsp;...
