Description: ;============================================================================= ; ADD-2.ORC ; SIMPLE ADDITIVE SYNTHESIS (FROM ACCCI, 02_41_1.ORC) / MONO ; AMPLITUDE ENVELOPE WITH LINEN ;============================================================================= ; Timbre: Brass ; Synthesis: Additive, same building blocks units ; Basic instrument with added random frequency variation ; Source: #200, Brass-like Sounds through Independent Control of ; Harmonics, Risset (1969) ; Coded: jpg 8/93, modified ms 9/02, 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 = max amp [linear, >0.0-1000.0 or dB, <= 0.0] ; p5 = fundamental freq [Hz] ; p6 = attack time of the amp envlp [sec] ; p7 = decay time of the amp envlp [sec] ; p8 = spectral scaler for the fund freq ; p9 = % of jitter (low-freq random freq variation) [0-1] ;----------------------------------------------------------------------------- ; COMPULSORY GEN FUNCTIONS : ; f1 audio wave ;_____________________________________________________________________________ | |||||||||||||||||||||||||||||||||||||||||||
