Teem PM Tus Kheej rau [75%].
Teem Decay (Comb Filter) rau [1260 ms] thiab Hi Hlais rau [120.00 st].
Tam sim no peb tab tom tsim ib qho kev tawm tswv yim tshwj xeeb routing:
Nias Comb Mix (State Variable Filter). Tig lub encoder rau [100.0%]. Nias SV Filter (Feedback Tov Khoom). Tig lub encoder rau [50.0%]. Nias FB Mix (Oscillator A). Tig lub encoder rau [25.0%].
Tam sim no Lub Xeev Hloov Hloov Lim Lim yog muab tso rau hauv txoj kev tawm tswv yim thiab tab tom ua cov teeb liab tuaj txog ntawm Comb Filter.
Nias Spread (State Variable Filter) kom txog thaum [L – B – H] qhib. Tig lub Encoder rau [50.0 %] kom pab tau qhov kev teeb tsa bandpass. Nias Reson (State Variable Filter). Tig lub Encoder rau [75.0%].
SV Filter tam sim no ua hauj lwm raws li qhov nqaim band-pass, xaiv cov zaus band rau cov lus tawm tswv yim.
Xovxwm Cutoff (State Variable Filter). Sweep tus Encoder maj mam hla tag nrho cov ntau yam thiab hu rau tus nqi uas
pleases koj pob ntseg, cia peb hais [80.0 st]. Kev tsim cov lus teb tawm tswv yim siv SV Lim ua kom zoo nkauj
timbral kev tshwm sim. Los ntawm kev hloov lub bandpass, nws tus kheej oscillation tshwm tsuas yog thaum lub band sib phim ib qho ntawm cov overtones uas lub Comb Filter tuaj yeem
tsim tawm. Sweeping SV Filter Cutoff yuav tsim ib tug qauv ntawm overtones. Thov nco ntsoov tias txhua yam koj tau hnov txog cov teeb liab tawm ntawm Comb Filter SV Filter tsuas yog ib feem ntawm txoj kev tawm tswv yim (nruab nrab ntawm Comb Filter thiab Feedback Tov Khoom) thiab muab cov lus qhia xaiv xaiv. Oscillator A excites lub Comb Filter thiab tsis hnov zoo li ntawd.
... los ntawm kev siv cov txiaj ntsig tso tawm raws li cov lus qhia tawm tswv yim:
Lwm txoj hauv kev nthuav dav los tsim cov comb lim / lub cev qauv lub suab ntawm C15 yog siv txoj hauv kev tawm tswv yim ntawm ntu cuam tshuam. Ua ntej, lov tes taw SV Filter hauv txoj kev tawm tswv yim ntawm Comb Filter (ntawm chav kawm, Cov Lus Qhia Cov Khoom Siv muab ob peb txoj hauv kev tawm tswv yim sib luag tab sis, rau lub sijhawm no, peb xav khaws tej yam yooj yim):
Nias SV Filter (Feedback Tov Khoom).
Tig lub encoder rau [0.0%].

Suab Tsim Kho
Pub rov qab cov teeb liab los ntawm qhov cuam tshuam seem mus rau Comb Filter:
Xovxwm Teebmeem (Cov Lus Teb Sib Tsoo). Tig lub Encoder maj mam nce thiab hu rau hauv tus nqi uas tsim cov khoom noj me me-
rov qab suab. Tus nqi ib puag ncig [50.0%] yuav tsum ua haujlwm zoo. Nias qhov Mix parameter ntawm txhua qhov cuam tshuam thiab hu rau hauv tus nqi sib xyaw siab.
Tam sim no koj tab tom hnov cov lus tawm tswv yim teeb liab ntawm cov cuam tshuam saw txaus siab rau lub zuag lim. Thaum ua li ntawd, koj yuav (cia siab) xav tsis thoob los ntawm qee tus staggering soundscapes. Txhua qhov teebmeem ntawm tus kheej muab kev kho mob sib txawv ntawm cov lus qhia tawm tswv yim thiab yog li ua rau muaj txiaj ntsig sib txawv rau lub suab nrov. Txee tej zaum yuav raug siv los hloov cov ntsiab lus sib haum xeeb thaum lub Gap Filter (uas yog ib pawg tsis lees paub cov lim uas txiav tawm qee qhov ntau zaus) yog qhov tseem ceeb los tswj cov zaus teb ntawm cov lus qhia tawm tswv yim. Flanger, Echo, thiab Reverb feem ntau ntxiv cov khoom sib txawv thiab cov lus tsa suab rau lub suab. Thov nco ntsoov tias tus nqi ntawm reverb nyob rau hauv txoj kev tawm tswv yim tuaj yeem hloov kho nyias los ntawm Rev Mix parameter ntawm Cov Lus Qhia Tos.
