Asymmetrical frequency modulation (AFM) as proposed by Palamin et al.
(1988) offers greater flexibility in the shaping of the spectra of syn
thesized waveforms as compared to normal frequency-modulation (FM) syn
thesis. The feasibility of using AFM synthesis for the real-time gener
ation of waveforms of musical instruments is demonstrated using a DSP5
6000 digital signal processor to implement the AFM algorithm.
