Amplifier modelling (yomwe imadziwikanso kuti amp kuwonetsera kapena amp emulation) ndi njira yotsanzira amplifier yakuthupi monga gitala amplifier. Kujambula kwa amplifier nthawi zambiri kumafuna kukonzanso phokoso la mtundu umodzi kapena zingapo za vacuum chubu amplifiers komanso nthawi zina komanso zokulitsa zolimba.
Introduction
Chitsanzo cha amplifier ndi njira yofanizira mawonekedwe a mapangidwe osasinthika a analogi amplifier pamagetsi, ma amps a digito. Ndi ma modelling amplifier, oimba ndi mainjiniya amawu amatha kubwerezanso phokoso ndi kumverera kwa amplifiers akale osafunikira kuyendayenda mozungulira ma amp achikhalidwe olemera komanso okwera mtengo.
Kujambula kwa amplifier kumatheka pogwiritsa ntchito ukadaulo wapamwamba womwe umafunikira kuphatikiza makina apamwamba kwambiri amagetsi, mapulogalamu amphamvu apulogalamu ndi topology yovuta. Kupyolera mu kuphatikiza uku, amp modeler amatha kukonzanso machubu, ma pre-amps, ma toni, zigawo za speaker ndi zina zomwe zimapezeka mu classic amplifier ya analogi; kupanga chithunzi cholondola chomwe chimapanga nyimbo za gitala zamoyo.
Ubwino kwa amp modelers ndi kunyamula; ndi ang'onoang'ono kuposa zokulitsa zachikhalidwe zomwe amatengera ndipo nthawi zambiri zimakhala zosavuta kuzinyamula kuchokera kumalo ena kupita kwina. Amp modelers alinso ndi maubwino ena monga:
- Kusinthasintha kosinthika kwakusintha kwamawu
- Zinthu monga kuthekera kwa "kuwongolera" kuyendetsa chizindikiro molunjika kuchokera ku amp kudzera pa bolodi losakanikirana kapena mawonekedwe ojambulira
- Kupeza mawu otsitsa kuchokera kwa opanga osiyanasiyana
- Ndi zina zambiri.
Kodi Amplifier Model ndi chiyani?
Chitsanzo cha amplifier, wotchedwanso a Digital Amp Modeler (DAM) ndi mtundu wa mapulogalamu omwe amakulolani kuti mutengere phokoso la mitundu yosiyanasiyana ya amplifiers a gitala. Zitsanzozi zimagwira ntchito poyesa magetsi a ma amp osiyanasiyana, kujambula ndi kukonza phokoso la amp ndikuwagwiritsa ntchito ku gwero lililonse. Nthawi zambiri, kutengera ma amplifier kumatha kukuthandizani kuti mukwaniritse kamvekedwe ka amp classic, kapena kupanga mawu apadera.
Tsopano tiyeni tione mmene ntchito za amplifier modelling:
Mitundu ya Zitsanzo za Amplifier
Amplifier modeling, yomwe nthawi zina imatchedwanso amp modelling or amp-model ndi mtundu wa makina opangira digito omwe amagwiritsidwa ntchito kutengera kumveka kwa mitundu yosiyanasiyana ya zida. Ma Amplifiers amagwiritsidwa ntchito mumitundu yambiri yanyimbo komanso kuthekera kopanga ma amplifiers awa kumatha kuchepetsa nthawi ndi ndalama zofunikira kuti mupeze nyimbo zatsopano.
Pamlingo wake wofunikira kwambiri, woyimira amplifier amatenga chizindikiro choyambirira (kuchokera ku chida), kutengera mbali zina zamakina amtundu wa ma preamp, ma crossovers ndi ma equalizer ndikuzitulutsa kudzera mwa okamba. Izi zimakulolani kuti mukwaniritse ma toni kuchokera ku ma amplifiers osiyanasiyana popanda kudutsa kukhazikitsidwa kwa zida zakuthupi.
Pali mitundu ingapo yamitundu yama amplifier yomwe imapezeka pamapulatifomu osiyanasiyana, monga:
- Wolimba-chitsanzo: Kompyuta imakugwirirani ntchito zonse popanganso mawu apamwamba. Imasanthula mafunde anu amawu olowetsamo kenako imagwiritsa ntchito masamu kuti ibwerezenso pakompyuta.
- Zophatikiza: Izi zimaphatikizapo kuphatikiza zida zakuthupi ndi pulogalamu yoyeserera kuti mupange mawu atsopano kapena kukonzanso mawu omwe alipo.
- Mapulogalamu Achitsanzo: Izi zimaphatikizapo kutulutsa mawu mkati mwa mapulogalamu apulogalamu, kukulolani kuti muthenso kamvekedwe ka analogi popanda kuwononga ndalama zilizonse zokhudzana ndi kuyesa ma amps osiyanasiyana m'masitolo ogulitsa.
Ubwino wa Amplifier Modelling
Chitsanzo cha amplifier ndi njira yatsopano yotchuka ya osewera gitala. Poyerekeza ndi digito mitundu yosiyanasiyana ya ma amplifiers ndi makabati olankhulira, kutengera kakulidwe ka amplifier kumapereka mwayi kwa oimba magitala kuti azitha kusinthana pakati pa ma amplifiers osiyanasiyana osasintha zida kapena kusinthira pamanja pamikono ya amp. Izi zitha kukhala zopulumutsa nthawi komanso kupangitsa kuti zisudzo zikhale zosavuta.
Kugwiritsa ntchito makina amplifier kumatha kukhala kosavuta, koma palinso maubwino ena. Kujambula kwa amplifier kumalola oimba magitala kuti afufuze mitundu yosiyanasiyana ya mawu ndi ma toni osagwiritsa ntchito ndalama pakukhazikitsa kangapo kapena kupereka chida chonse kuti angomva phokoso linalake. Zimapangitsanso kukhala kosavuta kwa osewera omwe akuvutika ndi malo ocheperako, monga osewera a bass omwe angafune kugwiritsa ntchito combo amp yawo yakale koma malo ochepa amawalepheretsa kukhazikitsa ma cab angapo kuzungulira iwo. Pomaliza, fanizo la amplifier limawonjezera kusinthasintha popanga kupanga ndi mawu chifukwa mutha kugwiritsa ntchito kuchuluka kosawerengeka kwa ma amps ndi makabati omwe amakupatsani zomwe sizinachitikepo. kusintha kwa kamvekedwe ka mawu.
Kodi Modelling ya Amplifier Imagwira Ntchito Motani?
Chitsanzo cha amplifier ndi njira yotchuka kwambiri kuti oimba gitala atenge mawu osiyanasiyana kuchokera ku hardware yawo. Tekinoloje iyi imapanganso phokoso la zida zamayimbidwe, ma pedals ndi amplifiers, kulola osewera sinthani mosavuta pakati pa malankhulidwe osiyanasiyana ndi makonda amawu ndi kukhudza kwa batani.
M’nkhaniyi tiona momwe amplifier modeling amagwirira ntchito ndi phindu amapereka kwa osewera gitala.
Kugwiritsa Ntchito Chizindikiro cha Digital
Kuti muyesere phokoso la amplifier popanda kukhala nayo, muyenera kugwiritsa ntchito kukonza ma sign a digito (DSP). Imagwira ntchito lero monga momwe idachitira mu 2003, pomwe Line 6 idatulutsa chida chawo choyamba chopangira ma hardware, POD.
Kukonza ma siginecha a digito kumagwiritsa ntchito masamu masamu kutengera njira za analogi, pamenepa kutsanzira phokoso la amplifiers akale. Zimaphatikizapo ma aligorivimu omwe amayesa kutsanzira molondola kukula kwa dera la analogi ndi zigawo zake zonse powerengera zinthu monga panopa, voltage ndi toni stacks. Zotulutsazo zimasinthidwa kukhala mawu a digito omwe amatha kutumizidwa ku amplifier kapena speaker powered.
Njira yoyambira imaphatikizapo kutenga mawonekedwe omvera a digito (monga omwe amapangidwa ndi kiyibodi kapena chojambula cha gitala), kuyisintha ndi magawo angapo a zosefera za DSP ndikuzisakaniza ndi 'masitaelo a cab' ndi mafanizidwe a maikolofoni. Unyolo wa ma Signal utha kukhala wovuta kwambiri kulola ogwiritsa ntchito kupanga mawu apadera kuphatikiza ma cab, ma mics ndi ma pedals komanso magawo amp monga phindu ndi zosintha za EQ.
Ngakhale luso lachitsanzo lafika patali kuyambira 2003 pali zosintha zambiri zomwe zingapangidwe monga kupereka mwayi wopeza zitsanzo zamtundu wapamwamba kuchokera ku zodzikongoletsera zodziwika bwino m'mbiri yonse komanso kubwereza kolondola kwa zitsanzozo. Ngakhale luso lachitsanzoli ndilotchuka kwambiri pakati pa oimba magitala chifukwa cha kuphweka kwake, kugulidwa, kuthekera kwa tonal komanso kusinthasintha kwa ma amp achikhalidwe - kupatsa osewera mphamvu zomwe sizinachitikepo pamasewera awo.
Ma Modelling Algorithms
Chitsanzo cha amplifier ndi njira yosinthiranso phokoso la amplifier pogwiritsa ntchito masamu. Amagwiritsidwa ntchito kwambiri muzokulitsa zamakono zamakono ndi ma pedal units kuti apange phokoso la machubu amtundu wa analogi kuchokera ku gitala lamagetsi.
Njirayi imaphatikizapo kusanthula chizindikirocho kuchokera ku amplifier yeniyeni ndikumasulira mu algorithm yowongolera yomwe imatha kuyimira mawonekedwe ake a sonic. Algorithm iyi, yomwe imadziwikanso kuti "lachitsanzo,” kenako amaphatikizidwa ndi pulogalamu yapachipangizo cha digito yomwe imatha kusintha mawonekedwe a mafunde kapena mafunde kuti apangitsenso mamvekedwe amtundu wa amp kapena zida zina. Phokosoli limapangidwa kuti lifanane ndi mawonekedwe amtundu umodzi kapena zingapo zomwe zimatulutsanso bwino mawu a amplifier okhala ndi milingo yambiri yopindula, ma toni, zofananira ndi zoikamo.
Zida zambiri zopangira ma amplifier zimagwiritsa ntchito ukadaulo wotchedwa FFT (Fast Fourier Transform), yomwe imagwiritsa ntchito ma aligorivimu a digito kuti ipange zoyeserera zenizeni zenizeni potengera mitundu ingapo ya zolowetsa ma siginecha monga kulowetsa mwachindunji ndi kujambula maikolofoni. Zitsanzozo zimafanizira chizindikiro chilichonse chomwe amajambula ndi masamu awo kuti apange zofananira molondola ndi zokulitsa zoyambira ndipo zimathanso kuganizira zinthu monga:
- Vacuum chubu
- Mtundu wa wokamba nkhani
- kukula nduna
- Ma acoustics a panyumba
popanga zoyerekeza.
Kutsanzira Amplifier
Kutsanzira amplifier ndi gawo lofunikira la amplifiers amakono. Zimalola kupotoza, kuponderezana, ndi zotsatira zina za ma amplifiers angapo kuti abwerezedwe popanda kubweretsa ma amps onse.
Ukadaulo kumbuyo kutsanzira amplifier zachokera kukonza ma sign a digito (DSP). Lingaliro ndiloti mutenge chizindikiro, yambani ndikufanizira amplifier yeniyeni ndiyeno muikonze molingana ndi mawu omwe mukufuna. Pochita izi, mutha kupeza mitundu yosiyanasiyana yamitundu ndi zotsatira, monga kupotoza kovutirapo kapena mawu akuya ndi kuchedwa.
Izi ndi zotheka chifukwa osakaniza magawo ntchito kuti anamanga aliyense amplifier emulator monga kuyendetsa, mphamvu yotulutsa mphamvu, luso lopanga ma toni ndi zina. Zokonda izi zimawongoleredwa ndi mawonekedwe osavuta ogwiritsira ntchito pa otsatsira ambiri omwe amapereka mwayi wopeza ma amp amamvekedwe amitundu yosiyanasiyana, masitayilo ndi mitundu.
Njira zosiyanasiyana zimagwiritsidwanso ntchito pakuyerekeza mawu ojambulidwa omwe amaphatikiza zosefera za Hardware kapena mapulogalamu otengera kutsika kwapansi kapena zofananira komanso kusanthula ma aligorivimu omwe amayesa kuzindikira mawonekedwe akulu a amplifier kuchokera pamawu omwe adajambulidwa kale omwe adatengedwa kuchokera ku ma amps enieni. Izi zimapangitsa kuti pakhale zochitika zapadera pakati pa zotsika, zapakati ndi zokwera mkati mwazolowetsa zomwe zilipo kuti ogwiritsa ntchito atengerepo mwayi popanga mawu omwe akufuna.
Kutsiliza
Mwachidule, mawonekedwe amplifier ndi njira yotsogola yotsogola yomwe imatsanzira mamvekedwe amitundu yosiyanasiyana yamagitala amplifiers. Pogwiritsa ntchito kuphatikiza kwa ma aligorivimu osintha ma sign a digito ndi zamakono zamakono zamakono, wogwiritsa ntchito amatha kulamulira kamvekedwe kake, kupeza mapangidwe komanso kusintha magawo osiyanasiyana a amplifier monga preamp kapena machubu kuti apeze mawu awo omwe akufuna.
Ngati mukuyang'ana njira yowonjezerera zosankha zanu za tonal popanda kuyika ndalama pogula ma amp angapo, ndiye kuti kutsanzira kokulitsa kungakhale koyenera kwa inu. Ndi zosankha zambiri zomwe zilipo masiku ano, palibe malire pazomwe mungapange!
