Poltergeist - SuperCollider



Il termine poltergeist deriva dal tedesco e significa spirito rumoroso (geist significa spirito, poltern bussare).

PMOsc phase modulation oscillator pair

PMOsc.ar(carfreq, modfreq, pmindex, modphase, mul, add)

Phase modulation sine oscillator pair.
carfreq - carrier frequency in cycles per second.
modfreq - modulator frequency in cycles per second.
pmindex - modulation index in radians.
modphase - a modulation input for the modulator's phase in radians
