Kwagura

Bivuga niba indangururamajwi ishyigikira uburyo bwo kwinjiza amajwi inshuro nyinshi icyarimwe, niba hari uburyo bwo kwinjiza amajwi bukoreshwa mu kumenyekanisha amajwi mu buryo butaziguye, niba ifite uburyo bwo kwinjiza amajwi bwa USB, nibindi. Umubare wa subwoofer zishobora guhuzwa n'indangururamajwi zo hanze ni kimwe mu bipimo byo gupima imikorere y'ingufu. Interface z'indangururamajwi zisanzwe zigizwe ahanini na analog na USB. Izindi, nka optique fiber interfaces na digital interfaces nshya, ntabwo zikunze kugaragara cyane.

Ingaruka z'amajwi

Ikoranabuhanga rikoreshwa cyane mu gukora amajwi ya 3D ririmo SRS, APX, Spatializer 3D, Q-SOUND, Virtaul Dolby na Ymersion. Nubwo bafite uburyo butandukanye bwo gushyira mu bikorwa, bose bashobora gutuma abantu bumva ingaruka z'amajwi zigaragara mu buryo butatu. Itatu za mbere zirakunze kugaragara. Icyo bakoresha ni inyigisho ya Extended Stereo, ari nayo yo gutunganya ikimenyetso cy'amajwi mu buryo bunyura mu nzira, kugira ngo uwumva yumve ko icyerekezo cy'amajwi cyagutse kikagera hanze y'indangururamajwi ebyiri, kugira ngo cyagure ishusho y'amajwi kandi abantu bagire ubushobozi bwo kumva umwanya n'uburyo butatu, bigatuma habaho ingaruka za stereo. Byongeye kandi, hari ikoranabuhanga ribiri ryo kongera amajwi: ikoranabuhanga rya servo rikora rya electromechanical (rikoresha ihame rya Helmholtz resonance), ikoranabuhanga rya BBE high-definition plateau sound reproduction system na ikoranabuhanga rya "phase fax", naryo rifite ingaruka runaka mu kunoza ubwiza bw'amajwi. Ku ndangururamajwi za multimedia, ikoranabuhanga rya SRS na BBE ryoroshye kurishyira mu bikorwa kandi rifite ingaruka nziza, rishobora kunoza imikorere y'indangururamajwi.

Ijwi

Bivuga ikimenyetso gifite uburebure bw'umurambararo runaka kandi busanzwe buhamye (pitch), mu buryo bw'imvugo, ijwi ry'ijwi. Biterwa ahanini n'uburebure bw'umurambararo. Ku ijwi rifite uburebure bw'umurambararo bugufi, ugutwi kw'umuntu gukira n'ijwi ryo hejuru, mu gihe ku ijwi rifite uburebure bw'umurambararo burebure, ugutwi kw'umuntu gukira n'ijwi ryo hasi. Impinduka mu ijwi rifite uburebure bw'umurambararo mu by'ukuri ni logarithmic. Ibikoresho bitandukanye bicuranga inota rimwe, nubwo ijwi ritandukanye, ariko ijwi ryabyo ni rimwe, ni ukuvuga ko umuraba w'ibanze w'ijwi ari umwe.

Igiti cy'umukara

Uburyo ijwi rigaragaramo ni na bwo buryo ijwi rimwe ribitandukanya n’irindi. Iyo ibicurangisho bitandukanye bicuranga ijwi rimwe, ijwi ryabyo rishobora gutandukana cyane. Ibi biterwa nuko imiraba yabyo y’ibanze ari imwe, ariko ibice bya harmonic biratandukanye cyane. Kubwibyo, ijwi ntirishingira gusa ku muraba w’ibanze, ahubwo rinafitanye isano ya hafi n’amajwi ari igice cy’ingenzi cy’umuraba w’ibanze, bituma buri gikoresho cya muzika na buri muntu bagira ijwi ritandukanye, ariko ibisobanuro nyabyo ni iby’umuntu ku giti cye kandi bishobora kumvikana nk’amayobera.

Ihindagurika

Igipimo cy'ijwi rikomeye n'iry'intege nke mu ijwi, kigaragazwa muri dB. Urugero, itsinda rifite urwego ruhindagurika rwa 90dB, bivuze ko igice gito cyane gifite imbaraga nke za 90dB ugereranyije n'igice kinini cyane. Ingano ihindagurika ni igipimo cy'imbaraga kandi ntaho gihuriye n'urwego rw'ijwi ruhoraho. Nkuko byavuzwe mbere, urwego ruhindagurika rw'amajwi atandukanye mu miterere narwo rurahinduka cyane. Ikimenyetso rusange cy'imvugo ni hafi 20-45dB, kandi urwego ruhindagurika rwa symphony zimwe na zimwe rushobora kugera kuri 30-130dB cyangwa hejuru. Ariko, bitewe n'imbogamizi zimwe na zimwe, urwego ruhindagurika rw'amajwi rudakunze kugera ku rugero ruhindagurika rw'ijwi. Urusaku rw'igikoresho gifata amajwi rugena ijwi rito cyane rishobora gufatwa, mu gihe ubushobozi ntarengwa bw'ibimenyetso (urwego rwo kugoreka) bya sisitemu bugabanya ijwi rikomeye cyane. Muri rusange, urwego ruhindagurika rw'ibimenyetso by'amajwi rushyirwa kuri 100dB, bityo urwego ruhindagurika rw'ibikoresho by'amajwi rushobora kugera kuri 100dB, ibyo bikaba ari byiza cyane.

Harmonic zose

Bivuga ibice by’uruhererekane rw’ibimenyetso bisohoka biterwa n’ibice bitari umurongo ugororotse kuruta ikimenyetso cyinjiye iyo isoko ry’ibimenyetso by’amajwi rinyuze muri amplifier y’ingufu. Guhindagurika kwa harmonic guterwa n’uko sisitemu idahuza neza, kandi tubigaragaza nk’ijanisha ry’ikigereranyo cy’ibanze cy’igice cy’uruhererekane cy’ibimenyetso bishya by’uruhererekane rw’ibimenyetso ku gaciro ka rms k’ibimenyetso by’umwimerere.
