Description: ;============================================================================= ; FM-2.ORC ; FREQUENCY MODULATION (FROM ACCCI, 20_10_1.ORC) / MONO ; AMPLITUDE AND INDEX ENVELOPES WITH OSCILI ; SAME AS FM-1.ORC, BUT WITH FREQ INSTEAD OF N1 ;============================================================================= ; Synthesis: FM with dynamic spectral evolution ; Bell settings ; Source: Chowning (1973) ; Coded: jpg 8/92, modified ms 1/08, 8/08 ; NB: NEW STRUCTURE FOR THE AMPLITUDES FROM AUGUST 2008! ; Positive value > 0.0 : linear amplitude (>0.0-1000.0) ; 0.0 or negative value : amplitude in dB (0 = maximum value) ; The apparently arbitrary amplitude range (0-1000, rather than 0-1) ; avoids printing small values with exponential notation ; Replaced oscili with poscil (precise oscillator), ms 8/08 ; Default SR = 96000, recommended precision: 24 bits ;----------------------------------------------------------------------------- ; p1 = instrument number ; p2 = action time [sec] ; p3 = duration [sec] ; p4 = maximum amp [linear, >0.0-1000.0 or dB, <= 0.0] ; p5 = fundamental freq [Hz] ; p6 = freq of the carrier [Hz] ; p7 = N2 ; p8 = max index ; p9 = min index ; p10 = amp envelope [GEN number] ; p11 = index envelope [GEN number] ;----------------------------------------------------------------------------- ; COMPULSORY GEN FUNCTIONS ; f1 carrier audio wave (sine tone) ; f2 modulating audio wave (sine tone) ;_____________________________________________________________________________ | |||||||||||||||||||||||||||||||||||||||||||||||||
