Ngaphandle kwe-Volume Control - Uluhlu lweDynamic, Ukunyanzeliswa, kunye neNtloko
Zininzi izinto ezenza ukuba zibe neengcamango ezifanelekileyo kwiimeko zokulalela ezithengileyo. Ukulawula ivolumu yindlela eyona nto ininzi ifumana inqanaba lokuphulaphulisa ngokukhululekile, kodwa ayikwazi ukuyenza yonke loo msebenzi. Igumbi lekhanda elinobuchule, ububanzi obunamandla, kunye nokunyanzeliswa okunamandla yimiba eyongezelelweyo enokuba negalelo ekuphulaphuleni induduzo.
Indlu yeNtloko-Ngaba unamandla angakumbi Xa ufuna?
Isandi sokuzalisa igumbi, isamukeli somdlalo we-stereo okanye sekhaya kufuneka usebenzise amandla okwaneleyo kwisithethi sakho ukuze uva umxholo. Nangona kunjalo, ekubeni amanqanaba omsindo atshintsho rhoqo kwiirekhodi zomculo kunye namafilimu, ummkeli kufuneka ahlengahlengise umbane wayo ngokukhawuleza ngendlela efanelekileyo.
Igumbi lekhanda elimandla libhekisela kwikhono lokufumana i-stereo / home hall, okanye i-amplifier, ukukhupha amandla kumgangatho ophakamileyo kakhulu kwixesha elifutshane ukulungiselela ukuphakama komculo okanye iziphumo ezivakalayo kwiifilimu. Oku kubaluleke kakhulu kwimidlalo yaseshashalazini, apho utshintsho oluninzi lwangaphakathi luqhubeka ngexesha lefilimu.
Igumbi lekhanda elimangalisayo lilinganiselwa kwi- Decibels (dB) . Ukuba i-receiver / amplifier inakho ukuphindaphinda amandla okuqhubekayo okuvelisa amandla okwenza ixesha elifutshane ukulungiselela ukuphakama kwevolumu, ine-3db yamagumbi okuqala. Nangona kunjalo, ngokuphindwe kabini ukuveliswa kwamandla akuthethi ukuphindaphinda kabini umthamo. Ukuze kuphindwe kabini ivolumu ukusuka kwinqanaba elinikeziweyo, ummkeli / amplifier kufuneka akhulise umbane walo mveliso nge-10.
Oku kuthetha ukuba ukuba ummkeli / amplifier uvelisa i-watts ezili-10 kwinqanaba elithile kwaye utshintsho oluzenzekelayo kwi-soundtrack ludinga kabini ivolumu ngexesha elifutshane, umxhasi we-amplifier / ummkeli kufuneka akwazi ukuvelisa ngokukhawuleza ama-watts ayi-100.
Ubuninzi bekhanda lamandla okubhakabhaka bhakawa kwi-hardware ye-receiver okanye i-amplifier, kwaye ayikwazi ukulungiswa. Eyona nto, i-receiver ye-homeatre ene-3db okanye ngaphezulu kwendlu yamakhanda enamandla yintoni oya kukhangela. Oku kungabonakaliswa ngephakamiso yesiphakamiso sokwenza umbane-umzekelo, ukuba ukuphakanyiswa kombane, okanye ukuguqula amandla, ukulinganiswa kwamandla okuphindaphinda kabini inani le-RMS, eliqhubekayo okanye le-FTC elilinganiselwayo, eli 3db igumbi eliphezulu.
Ukuba ungaqhelekanga ngendlela amandla omshukumisi asebenza ngayo, khangela iqaku lethu kwindlela amandla amplifier ahambelana ngayo nokusebenza komsindo .
Dynamic Range-Soft vs Loud
Kwi-audio, uluhlu olushukumisayo ngumlinganiselo wesandi esikhulu kakhulu esingafaniyo esenziwe ngokubhekiselele kwisandi esincinci esisaqondakalayo. I-1dB yinto ebonakalayo encinci yevolumu eyenziwa yindlebe yomntu. Ukwahlukana phakathi kwekhenkethi enkulu kunye nekhonsathi enkulu yomlambo (kwimizuzu efanayo ukusuka kwindlebe yakho) malunga ne-100dB.
Oku kuthetha ukuba usebenzisa i-dB, i-concert ye-rock iyamaxesha angaphezu kwezigidi ezili-10 ubude ngaphezu kwe-whisper. Ngomculo orekhodiweyo, i- CD ephezulu iyakwazi ukuvelisa i-100db yoluhlu olushukumisayo, ngelixa irekhodi le-LP likhupha malunga ne-70db.
I-Stereo, abalamkeli bemidlalo yaseshashalazini, kunye nezixhobo ezikhuphayo ezingakwazi ukuvelisa uluhlu olushukumisayo lweCD okanye omnye umthombo onokuvelisa uluhlu olubanzi olunamandla olufanelekileyo.
Kakade, enye ingxaki ngomxholo womthombo orekhodwe ngoluhlu olubanzi oluvakalayo lwamazwi kukuba "umgama" phakathi kwezona zinto zilula kwaye zikhulu kakhulu ziyakucasula.
Umzekelo, kwimimandla engavumelaniyo, i-vocal ingabonakala igxothwa yimpahla yangasemuva nakwiimviezo, incoko yababini inokuba yincinci ukuba iqondwe, ngelixa iziphumo zomsindo ezizodwa zingenakukuphazamisa nje kuphela kodwa nabamelwane bakho.
Le yilapho iDynamic Compress ingena khona.
Inkqubo yokuDityaniswa kweDynamic -Cqueezing Dynamic Range
Ukunyanzeliswa kweDynamic akubhekiseli kwiintlobo zeefomati zoxinzelelo ezisetyenziswe kwi-digital audio (cinga i-MP3). Kunoko, ukuxinwa okunamandla kuyithuluzi evumela ukuba umphulaphuli atshintshe ubuhlobo phakathi kweengxenye eziphezulu kakhulu zesandi kunye neengxenye eziqinileyo zesandi xa udlala iCD, iDVD, i-Blu-ray Disc, okanye enye ifomathi yefayile yomculo.
Ngokomzekelo, ukuba ufumanisa ukuba ukuqhuma okanye ezinye izakhi zomsindo zikhulu kakhulu kwaye intetho yencoko ithambile kakhulu, ufuna ukunciphisa ububanzi obushukumisayo obukhoyo kwi-soundtrack. Ukwenza njalo kuya kwenza izandi zeentshukumo kungekhona ngokuzwakalayo, kodwa incoko yababini izandila ngokukhawuleza. Oku kuya kwenza ukuba isandi siphelele ngakumbi, sinobalulekileyo xa udlala iCD, iDVD, okanye i-Disc-Blu-ray kwiqondo eliphantsi.
Kwiimvumi zecala lasekhaya okanye izixhobo ezifanayo, inani lokuncincika okutshintshayo lugqitywa ngokusebenzisa ulawulo lokucwangcisa olunokuthi lubhalwe ukuxinwa okunamandla, ububanzi obunamandla, okanye i-DRC nje.
Iinkqubo ezinjalo zokulawula ukunyanzeliswa kwegama lomsebenzi ziquka i-DTS TruVolume, i-Dolby Volume, i-Zvox Accuvoice kunye ne-Audyssey Dynamic Volume. Ukongezelela, ezinye iindlela ezinamandla zokulawula / ukunyanzeliswa kwemisebenzi zingasebenza kwimithombo eyahlukeneyo (njengokuba xa utshintsha iziteshi kwiTV ukuze zonke iziteshi zisezingeni elifanayo levolumu, okanye zenze iintengiso ezinkulu kwiprogram yeTV).
Ngaphantsi
Igumbi lekhanda elinamandla, ububanzi obuqilileyo kunye nokunyanzeliswa okunamandla zizinto ezibalulekileyo ezichaphazela uluhlu lwomsindo ovakalayo olukhoyo kwiimeko zokuphulaphula. Ukuba ukulungiswa kwezi nqanaba akulungisi iingxaki onalo, cinga ukujonga ezinye izinto ezifana nokuphambukisa kunye neendawo zokubasa .
