foscili (Csound opcode) | ||
|
Basic frequency modulated oscillator with linear interpolation
ar foscili xamp, kcps, xcar, xmod, kndx, ifn [, iphs]
xamp: amplitude of the output signal
kcps: (fundamental [perceived]) frequency of the output signal xcar: kcps * xcar = carrier frequency xmod: xmod * kcps = modulating frequency (freq_mod) kndx: modulation index: kndx * kcps * xmod = kndx * freq_mod= modulation amplitude foscili.orc

BTW, fm synthesis shows how to generate signals without foscili but with two oscilators (oscili).
