Ukumodela kwe-Amplifaya (owaziwa nangokuthi amp Modelling noma i-amp emulation) inqubo yokulingisa isikhulisi esibonakalayo esifana nesandisi sesiginci. Ukumodela kwe-amplifier kuvame ukufuna ukuphinda udale umsindo wemodeli eyodwa noma ngaphezulu ethile yezikhulisi zamashubhu e-vacuum futhi kwesinye isikhathi nezikhulisi zesimo esiqinile.
Isingeniso
Ukumodela kwe-amplifier inqubo yokulingisa izici zemiklamo ye-analog ye-amplifier engaphelelwa isikhathi kuma-amp wokumodela anamandla, wedijithali. Ngokumodela kwe-amplifier, abaculi nonjiniyela bomsindo bayakwazi ukudala kabusha umsindo nomuzwa wezikhulisi zakudala ngaphandle kokudinga ukuzungeza ama-amp esindayo nabizayo.
Ukumodela kwe-amplifier kwenziwa ngobuchwepheshe obusezingeni eliphezulu obudinga inhlanganisela i-elekthronikhi eyinkimbinkimbi, izinhlelo zesofthiwe ezinamandla kanye ne-topology eyinkimbinkimbi. Ngale nhlanganisela, i-amp modeler ingakwazi ukwenza kabusha ngokunembile amashubhu, ama-pre-amps, izitaki zethoni, izingxenye zesipika neminye imiphumela etholakala ku-amplifier yakudala ye-analog; ukudala ukumelwa okunembile okukhiqiza amathoni esiginci afana nempilo.
Inzuzo kumamodeli we-amp ukuphatheka; mancane kunama-amplifiers endabuko abalingisayo futhi ngokuvamile kulula ukuwahambisa ukusuka kwenye indawo kuya kwenye. Amamodeli we-Amp nawo anezinzuzo ezengeziwe ezifana nalezi:
- Ukuguquguquka okulungisekayo kokulungisa umsindo
- Izici ezifana namakhono "okuphuma ngqo" okusebenzisa isignali ngokuqondile kusuka ku-amp ngokusebenzisa ibhodi lokuhlanganisa noma isixhumi esibonakalayo sokurekhoda
- Ukufinyelela kumisindo elandekayo evela kubakhi abahlukahlukene
- Futhi okuningi okuningi.
Iyini imodeli ye-Amplifaya?
Imodeli ye-amplifier, ebizwa nangokuthi i- I-Digital Amp Modeler (DAM) kuwuhlobo lwesoftware olukuvumela ukuthi uphindaphinde umsindo wezinhlobo ezahlukahlukene zama-amplifiers wesiginci. Lawa mamodeli asebenza ngokulingisa ama-electronics ama-amps ahlukene, athwebule futhi acubungule imisindo ye-amp futhi ayisebenzise kunoma yimuphi umthombo othile. Ngokuvamile, imodeli ye-amplifier ingakusiza ufinyelele ithoni ye-amp yakudala, noma udale imisindo ehluke ngokuphelele.
Manje ake sibheke ukuthi kanjani Imodeli ye-amplifier iyasebenza:
Izinhlobo zamamodeli we-Amplifaya
Imodeli ye-Amplifaya, nayo ngezinye izikhathi ebizwa ngokuthi amp modelling or i-amp-modeling wuhlobo lokucubungula kwedijithali okusetshenziselwa ukulingisa umsindo wezinhlobo ezahlukene zemishini. Ama-amplifiers asetshenziswa ezinhlobonhlobo zezinhlobo zomculo futhi amandla okwenza lezi zikhulisi zinganciphisa isikhathi nemali edingekayo ukuze uthole amathoni amasha.
Ezingeni layo eliyisisekelo, imodeli ye-amplifier izothatha isignali yoqobo (kuthuluzi), ilingise ezinye izingxenye zochungechunge lwesignali njengama-preamp, ama-crossovers nezilinganisi bese ikhipha ngezipikha ezibonakalayo. Le nqubo ikuvumela ukuthi ufinyelele amathoni avela kuma-amplifiers ahlukene ngaphandle kokuthi udlule ekusethweni kwehadiwe ngokomzimba.
Kunezinhlobo eziningana zamamodeli we-amplifier atholakala kumapulatifomu ahlukene, njenge:
- Imodeli eqinile: Ikhompyutha ikwenzela wonke umsebenzi ekudaleni kabusha imisindo yakudala. Ihlaziya amaza omsindo wakho ofakiwe bese isebenzisa izibalo zezibalo ukuze iwaphindaphinde ngogesi.
- Hybrid: Lokhu kuhlanganisa ukuhlanganisa ihadiwe ephathekayo nesofthiwe yokulingisa ebonakalayo ukuze udale imisindo emisha noma wenze ngcono imisindo ekhona.
- Isoftware Efanisiwe: Lokhu kuhilela ukukhiqiza imisindo ngaphakathi kwezinhlelo zesofthiwe, okukuvumela ukuthi udale kabusha ithoni ye-analog ngaphandle kokuthi ungene kunoma yiziphi izindleko eziphathekayo ezihlobene nokuzama ama-amps ahlukahlukene ezitolo zezitolo.
Izinzuzo ze-Amplifier Modelling
Ukumodela kwe-amplifier inketho esanda kuthandwa yabadlali besiginci. Ngokulingisa ngedijithali izinhlobo ezahlukene zezikhulisi namakhabethe ezipikha, ukumodela kwe-amplifier kunikeza abadlali besiginci ikhono lokushintsha kalula phakathi kwezikhulisi ezihlukene ngaphandle kokushintsha amathuluzi noma ukwenza ukulungisa okwenziwa ngesandla kuma-amp knob. Lokhu kungaba ukonga isikhathi okuhle futhi kwenze ukusebenza okubukhoma kube bushelelezi.
Ukusebenzisa imodeli ye-amplifier kungaba lula kakhulu, kodwa kunezinye izinzuzo futhi. Ukumodela kwe-amplifier kuvumela abadlali besiginci ukuthi bahlole izinhlobo ezahlukene zemisindo namathoni ngaphandle kokuchitha imali ekusetheni okuningi noma kudingeke ukuthi banikele yonke into ngomsindo othile. Futhi kwenza kube lula kubadlali abahlushwa yizimo zesiteji ezimpintshana, njengabadlali be-bass abangase bafune ukusebenzisa i-combo amp yabo endala kodwa isikhala esilinganiselwe sibavimbela ekufakeni amakhebhu amaningi eduze kwabo. Okokugcina, ukumodela kwe-amplifier kukhulisa ukuguquguquka mayelana nokwenza ubuciko ngemisindo ngoba ungasebenzisa inani elingenamkhawulo lezinhlanganisela zama-amps namakhabethe akunikeza okungakaze kubonwe ngaphambili. ukwehluka kwekhwalithi yethoni.
Isebenza Kanjani Imodeli Ye-Amplifaya?
Ukumodela kwe-amplifier kuyindlela ethandwa kakhulu yabadlala isiginci ukuze bathole imisindo ehlukene ku-hardware yabo. Lobu buchwepheshe budala kabusha umsindo wezinsimbi ze-acoustic, amaphedali omphumela nama-amplifiers, okuvumela abadlali ukuthi shintsha kalula phakathi kwamathoni ahlukene nezilungiselelo zomsindo ngokuthinta inkinobho.
Kulesi sihloko, sizobheka ukuthi imodeli ye-amplifier isebenza kanjani futhi izinzuzo inikeza kubadlali besiginci.
Ukusebenza Kwesiginali Yedijithali
Ukuze ulingise umsindo we-amplifier ngaphandle kokuba nayo, udinga ukuyisebenzisa ukucubungula isignali yedijithali (DSP). Isebenza namuhla njengoba yenza ngo-2003, lapho u-Line 6 ekhipha idivayisi yabo yokuqala ye-hardware amp-modeling, i-POD.
Ukucutshungulwa kwesignali yedijithali kusebenzisa ama-algorithms ezibalo ukuphindaphinda izinqubo ze-analog, kulokhu kulingisa umsindo wama-amplifiers akudala. Kubandakanya ama-algorithms azama ukulingisa ngokunembile ukuthuthukiswa kwesekethe ye-analog nazo zonke izingxenye zayo ngokubala amanani afana zamanje, voltage kanye nethoni izitaki. Okukhiphayo kube sekuguqulelwa kumsindo wedijithali ongathunyelwa ku-amplifier noma isipika esinamandla.
Inqubo eyisisekelo ihilela ukuthatha i-waveform yomsindo wedijithali (njengaleyo ekhiqizwe ngekhibhodi noma ukulandwa kwesiginci), ukuyiguqula ngezigaba eziningi zezihlungi ze-DSP bese uyixubela 'izitayela ze-cab' ezihlukene nokulingiswa kwemakrofoni. Amaketango esignali angaba yinkimbinkimbi kakhulu avumela abasebenzisi ukuthi benze imisindo ehlukile ngokusebenzisa inhlanganisela yamakhebhu, ama-mics namaphedali kanye namapharamitha we-amp afana inzuzo kanye nezilungiselelo ze-EQ.
Noma ubuchwepheshe bokumodela buhambe ibanga elide kusukela ngo-2003 kusenentuthuko eminingi engase yenziwe njengokuhlinzeka ukufinyelela kumamodeli akudala kakhulu avela kuma-amplifiers ayisithonjana kuwo wonke umlando kanye nokuphindaphinda okunembe kakhudlwana kwalawo mamodeli. Ngaphandle kwalobu buchwepheshe bokumodela budume ngendlela emangalisayo phakathi kwabadlala isiginci ngenxa yokusebenziseka kwabo, ukufinyeleleka, amathuba ethoni kanye nokuguquguquka kwama-amps endabuko - okunikeza abadlali ukulawula okungakaze kubonwe kulwazi lwabo lokudlala.
Ama-algorithms wokumodela
Ukumodela kwe-amplifier kuyindlela yokwenza kabusha ngokwedijithali umsindo weamplifier usebenzisa imodeli yezibalo. Ivamise ukusetshenziswa kuma-amplifiers edijithali yesimanje kanye namayunithi ama-pedal model ukudala umsindo wamashubhu e-analog amps endabuko kusuka kusiginci sikagesi.
Inqubo ihlanganisa ukuhlaziya isignali kusuka ku-amplifier yangempela bese isihumushela ku-algorithm yokulawula ekwazi ukumela izici zayo ze-sonic. Le algorithm, eyaziwa nangokuthi "imodeli,” ibe isihlanganiswa ohlelweni lwedivayisi yedijithali engashintsha amafomu amaza noma ama-oscillations ukuze idale kabusha imisindo ebangeni le-amp noma enye idivayisi yemiphumela. Imisindo ewumphumela ihlelelwe ukuthi ihambisane nefomu elilodwa noma ngaphezulu eliqondile elikhiqiza kabusha ngokunembile umsindo wesikhulisi esinamaleveli amaningi okuzuza, izitaki zethoni, izilinganisi nezilungiselelo.
Iningi lamadivayisi wokumodela ama-amplifier asebenzisa ubuchwepheshe obaziwa ngokuthi I-FFT (Fast Fourier Transform), esebenzisa ama-algorithms edijithali ukudala ukulingisa kokusebenza kwesikhathi sangempela okusekelwe ezinhlotsheni ezimbalwa zokufakwa kwesignali njengokufaka okuqondile nokuthwebula imakrofoni. Amamodeli abe eseqhathanisa isiginali ngayinye ayithwebulayo nefomula yawo yezibalo ukuze akhiqize ukukhiqizwa kabusha okunembile kuzikhuliseli zangempela futhi angacabangela izici ezifana nalezi:
- Vacuum amashubhu
- Uhlobo lwesipikha
- Usayizi weKhabhinethi
- I-acoustics yegumbi
lapho kukhiqizwa ukulingisa.
Ukulingisa Isikhulisi
Ukulingisa i-amplifier iyingxenye ebalulekile yama-amplifiers esimanje. Ivumela ukuhlanekezela, ukucindezelwa, neminye imiphumela yama-amplifiers amaningi ukuthi iphindaphindwe ngaphandle kokuthi empeleni ilethe wonke ama-amps.
Ubuchwepheshe obusemuva kokulingisa kwe-amplifier busekelwe ukucubungula isignali yedijithali (DSP). Umqondo wukuthi uthatha isignali, qala ngokulingisa i-amplifier ebonakalayo bese uyilungisa ngokuhambisana nomsindo owufunayo. Ngokwenza lokhu, ungathola uhla lwamathoni ahlukene nemiphumela, njengokuhlanekezela okuqinile noma isaga esijulile nokubambezeleka.
Lokhu kungenzeka ngenxa yenhlanganisela yamapharamitha asebenzayo akhelwe kusifanisi ngasinye se-amplifier njenge idrayivu, izinga lokuphuma kwamandla, amakhono okubumba ithoni futhi nokuningi. Lezi zilungiselelo zilawulwa ngesixhumi esibonakalayo esisebenziseka kalula kumamodeli amaningi anikeza ukufinyelela kumisindo ye-amp evela ezinkathini ezihlukene, izitayela namabhrendi.
Amasu ahlukahlukene aphinde asetshenziswe ekulinganiseni umsindo orekhodiwe ohlanganisa ihadiwe noma izihlungi ezisuselwe esoftware esezingeni eliphansi noma izilinganisi kanye nama-algorithms wokuskena azama ukuhlonza izici eziyinhloko zesilungiselelo se-amplifier kumasampuli omsindo arekhodiwe athathwe kuma-amps wangempela. Lokhu kuvumela ukusabela okuhlukile phakathi kokuphansi, okumaphakathi nokuphezulu ngaphakathi kokokufaka okutholakalayo ukuze abasebenzisi bazuze lapho benza umsindo abawuthandayo.
