Nweba

Kubhekisele ekutheni ngabe isipikha siyayisekela yini i-multi-channel input ngasikhathi sinye, ukuthi ngabe kukhona i-output interface yezipikha ezizungezile ezingasebenzi, ukuthi ngabe inomsebenzi wokufaka we-USB, njll. Inani lama-subwoofer angaxhunywa kuzipikha ezizungezile zangaphandle nalo lingenye yezindlela zokulinganisa ukusebenza kokunwetshwa. I-interface yezipikha ze-multimedia ezivamile zifaka phakathi i-analog interfaces kanye ne-USB interfaces. Ezinye, njenge-optical fiber interfaces kanye ne-innovative digital interfaces, azivamile kakhulu.

Umphumela womsindo

Ubuchwepheshe be-hardware obuvame kakhulu be-3D sound effects buhlanganisa i-SRS, i-APX, i-Spatializer 3D, i-Q-SOUND, i-Virtaul Dolby kanye ne-Ymersion. Nakuba zinezindlela ezahlukene zokusebenzisa, zonke zingenza abantu bazizwe bezwakala sengathi banemiphumela yensimu yomsindo enezinhlangothi ezintathu. Ezintathu zokuqala zivame kakhulu. Abakusebenzisayo yi-Extended Stereo theory, okuwukucubungula isignali yomsindo ngesekethe, ukuze umlaleli azizwe ukuthi isiqondiso sesithombe somsindo sinwetshiwe ngaphandle kwezikhulumi ezimbili, ukuze kwandiswe isithombe somsindo futhi kwenze abantu babe nomuzwa wesikhala kanye nobukhulu obuthathu, okuholela kumphumela we-stereo obanzi. Ngaphezu kwalokho, kunezindlela ezimbili zokuthuthukisa umsindo: ubuchwepheshe be-servo esebenzayo ye-electromechanical (ngokusebenzisa isimiso se-Helmholtz resonance), ubuchwepheshe besistimu yokukhiqiza umsindo we-plateau ephezulu ye-BBE kanye nobuchwepheshe be-"phase fax", obunomphumela othile ekuthuthukiseni ikhwalithi yomsindo. Kuzikhulumi ze-multimedia, ubuchwepheshe be-SRS kanye ne-BBE kulula ukubusebenzisa futhi bunemiphumela emihle, engathuthukisa ngempumelelo ukusebenza kwezikhulumi.

Ithoni

Kubhekisele esignalini esinobude besikhathi obuthile futhi obuhlala buzinzile (iphitch), ngokwesiko, ithoni yomsindo. Kuncike kakhulu kubude besikhathi. Ngomsindo onobude besikhathi obufushane, indlebe yomuntu iphendula ngephimbo eliphezulu, kanti ngomsindo onobude besikhathi obude, indlebe yomuntu iphendula ngephimbo eliphansi. Ushintsho lwephimbo ngobude besikhathi empeleni luyi-logarithmic. Izinsimbi ezahlukene zidlala inothi elifanayo, yize i-timbre ihlukile, kodwa ukuphakama kwazo kuyafana, okungukuthi, igagasi eliyisisekelo lomsindo liyafana.

I-Timbre

Ukuqonda ikhwalithi yomsindo nakho kuyikhwalithi ephawulekayo yomsindo owodwa owuhlukanisa komunye. Lapho izinsimbi zomculo ezahlukene zidlala ithoni efanayo, i-timbre yazo ingahluka kakhulu. Lokhu kungenxa yokuthi amagagasi azo ayisisekelo afana, kodwa izingxenye ze-harmonic zihlukile kakhulu. Ngakho-ke, i-timbre ayixhomekile kuphela kugagasi eliyisisekelo, kodwa futhi ihlobene eduze nama-harmonic ayingxenye ebalulekile yegagasi eliyisisekelo, okwenza insimbi ngayinye yomculo nomuntu ngamunye babe ne-timbre ehlukile, kodwa incazelo yangempela ihlukile kakhulu futhi ingase izwakale iyimfihlakalo.

I-Dynamic

Isilinganiso sonamandla kakhulu kunobuthakathaka kakhulu emsindweni, esivezwa ku-dB. Isibonelo, ibhendi inebanga eliguqukayo elingu-90dB, okusho ukuthi ingxenye ebuthakathaka kakhulu inamandla amancane angu-90dB kunengxenye enomsindo kakhulu. Ibanga eliguqukayo liyisilinganiso samandla futhi alinalutho oluphathelene nezinga eliphelele lomsindo. Njengoba kushiwo ngaphambili, ububanzi obuguqukayo bemisindo ehlukahlukene emvelweni buhlukahluka kakhulu. Isignali yenkulumo evamile ingama-20-45dB kuphela, kanti ububanzi obuguqukayo bezinye izinsimbi zomculo bungafinyelela ku-30-130dB noma ngaphezulu. Kodwa-ke, ngenxa yemikhawulo ethile, ububanzi obuguqukayo besistimu yomsindo abufinyeleli kakhulu ebangeni eliguqukayo lebhendi. Umsindo ongokwemvelo wedivayisi yokurekhoda unquma umsindo obuthakathaka kakhulu ongaqoshwa, kuyilapho umthamo wesignali omkhulu (izinga lokuhlanekezela) wesistimu ukhawulela umsindo oqinile kakhulu. Ngokuvamile, ububanzi obuguqukayo besignali yomsindo busethwe ku-100dB, ngakho ububanzi obuguqukayo bemishini yomsindo bungafinyelela ku-100dB, okuyinto enhle kakhulu.

Ama-harmonics aphelele

Kubhekisele ezingxenyeni ezengeziwe ze-harmonic zesignali yokukhipha ebangelwa izingxenye ezingezona eziqondile kunesignali yokufaka lapho umthombo wesignali yomsindo udlula ku-amplifier yamandla. Ukuphambuka kwe-Harmonic kubangelwa iqiniso lokuthi uhlelo aluqondile ngokuphelele, futhi sikuchaza njengephesenti lesikwele esiphakathi kwempande sengxenye ephelele ye-harmonic esanda kufakwa kunani le-rms yesignali yokuqala.
