Ukuhamba kahle igama lomdlalo uma kuziwa ekulaleleni umculo nezinye okuqukethwe komsindo emgwaqeni. Umsakazo umelela ekugcineni ekuphatheni, nakuba imidiya yemvelo njengama- cassette nama- CD nawo abone impumelelo enkulu ngenxa yemvelo ephatheka kalula yalezo zakhiwo, nomculo we-digital kuyaphathwa kakhulu, ngamadivayisi afana ne-iPod ekwazi ukubamba izinkulungwane zamathrekhi. Ukuqhutshwa kwamuva nje ekuthandweni kwe-audio-resolution resolution kuye kwaguqula inaliti ngendlela ehlukile, kuphakamisa umbuzo wokuthi ukuphatheka-noma ukukala kwefayili-kubaluleke kakhulu kunekhwalithi, noma ngabe empeleni kungenye indlela.
Kungani Ukubaluleka Kubaluleke Kangako Emotweni Yemoto?
Uma ubheka umlando wemisindo yemoto, okuningi kubonakala sengathi kuqhutshelwa kalula. Umsakazo wawuwumthombo wokuqala womsindo wemoto , futhi uhlala udumile kuze kube yilolu suku, ikakhulukazi ngenxa yokuthi kulula kangakanani. Umsakazo uvumela abashayeli ukuba balalele izinto ezihlukahlukene ngaphandle kokugxila kunoma imuphi umsakazo wezinto ezibonakalayo, futhi ukuthuthuka phakathi neminyaka kuye kwaholela ekuthembekeni okuqhubekayo kokulalelwayo ngokusakazwa kwe-airwaves.
Amaphayona emkhakheni we-audio car wazama ukukhulisa izinqumo zokulalela kuqala, ngezithombe zokuhlola ezitholakala emotweni , namanye ama-OEM ngisho ahlolwe lawo manzi, kodwa amarekhodi ekugcineni ayengenakutholakala ngokwanele. Kwakungekho kuze kube yilapho ifomethi yokulalelwayo ephathekayo kalula, ithrekhi engu-8 , iqala ukudlala ukuthi abashayeli bebekwazi ukuhamba ngokuzungeze ukukhetha komculo.
Kwabe sekufika amateyipu e-cassette, ayencane futhi kulula ukuwuthwala, futhi ama-CD, angabamba umculo omningi futhi aphezulu kakhulu.
Okokugcina, okuphelele ekuphatheni kwafika ngendlela yamafayela womculo we-digital njengama-MP3s, angashiswa kuma-CD-ngokuvamile ephethe umculo ophindwe kabili kunama-audio CD-kanye nama- MP3 njengama-iPod angabamba izinkulungwane zezingoma ngokufanayo inani lesikhala esingokwenyama esithathwe nge-cassette tape eyodwa.
Iyini ifomethi ye-Lossy Audio?
Ukuze wenze okuqukethwe komsindo kube nokuphathekayo, ukuthembeka kwe-audio ngokuvamile kuyinto yokuqala yokuhamba. I-Audiophiles isilinde isikhathi eside ukushintshwa kusuka kumafomu we-analog njengamarekhodi kumafomethi edijithali njenge-CD, kodwa ukuthuthela kuma-MP3s kwathatha izinyathelo eziqhubekayo.
Cishe wonke amafomethi omculo wedijithali asetshenziselwa kakhulu asethembele ekutheni "ukulahlekelwa" amasu okucindezela, okusho ukuthi okungenani ingxenye ethile yephrofayli yomsindo wokurekhoda kwasekuqaleni ilahlekile. Ezinye zazo zizobe zingaphandle kwezinga elijwayelekile lokuzwa kwabantu, kepha indlebe eqeqeshiwe ingasho ukuthi umehluko phakathi kokulahlekelwa okubizwa ngokuthi "ikhwalithi yeCD" umsindo wedijithali, njengokuqukethwe okutholakala iPod yasekuqaleni, nefayela elingaxhunyiwe .
Iyini i-High-Resolution Audio?
Ukuphakanyiswa okuphezulu, noma ukucaca okuphezulu, umsindo akuyona igama elinencazelo ecacile, kodwa ngokuvamile kubhekiswa kumafayela omculo we-digital anomsindo wekhwalithi engcono kune-CD. Ngokusho kwe-Crutchfield, i-MP3 evamile oyilanda kusuka ku-iTunes noma i-Amazon inezinga elilinganiselwa ku-256 kbps, kanti ifayela le-audio-24-bit / 96kHz eliphakeme eliphezulu likwazi ukulinganisa ama-kbps angu-4,000 noma cishe izikhathi ezine ze-audio CD .
Kunezinhlobo ezimbili eziyinhloko zamafayela alalelwayo aphezulu okuxazulula ukuthi ungathenga: amafayela angaxhunyiwe namafayela afakwe ucindezelwe nge-codec engalahleki. Amafayili alalelwayo angavinjelwe kakhulu afaka i-PCM, WAV, ne-AIFF ye-Apple. Izinhlobo ezimbili zamafayela ezilahlekile eziphefumulayo ziyi-FLAC, ezingenakudlalwa nge-iTunes noma idivayisi ye-Apple njenge-iPod ne-iPhones, ne-ALAC ye-Apple engadlalwa kumadivayisi we-Apple.
I-High-Resolution Audio Vs. Ukufaneleka
Kunezimpikiswano ezimbalwa nge-audio-resolution resolution, kufaka phakathi intengo nombuzo wokuthi ngabe umlaleli ophakathi angasho yini umehluko phakathi kokucindezeleka okungalahleki nokulahlekelwa. Kodwa-ke, inkinga enkulu ngokubhekelana nokulalelwayo okuphezulu nokuhleleka-kungakhathaliseki ukuthi yiyo umsindo wezimoto noma ukumane ulalele umculo kumdlali womculo ophathekayo-kuwukubonakala.
Omunye wamandla amakhulu kakhulu amafomethi alahlekile afana ne-MP3 ne-AAC yi-portability, eyasiza ukushayela ukwamukelwa kwama-MP3 njengama-iPod kuqala. Ngokusho kwabakwa-Consumer Reports, ungakwazi ukulinganisa amathrekhi angama-76 ku-gigabyte eyodwa yokugcina isikhala, ucabanga ukuthi izingoma zilinganiselwa emaminithi amane ubude futhi zicindezelwe ngokusebenzisa i-codec elahlekile ejwayelekile.
Uma uqhathanisa, ungafanelana namafayela we-WAV angama-27 e-CD esilinganisweni saleso sikhala, amafayela a-FLAC ayisikhombisa, noma amafayela ama-AIFF amahlanu kuphela.
Isikhala sokugcina i-Digital asiyona into enkulu njengoba isetshenziswa. Isizukulwane sokuqala se-iPod, njengesibonelo, sitholakale sibe nesamba esingu-10 GB esitoreji esiphezulu. Ngaleso sikhathi, i-iPod yashicilelwe njengoba ikuvumela ukuba uthwale izingoma ezizungezile ezingu-1,000, ngenxa yamafayela alalelwayo alalelwayo aphansi asetshenziswa ngaleso sikhathi. Ukusebenzisa izinombolo zombiko zabathengi kumafayela anomsindo wanamuhla, leso sikhala sisazobe sinezinhlamvu ezingaphezu kuka-700 AAC, kodwa sizokwazi ukugcina amafayela angama-AIFF angaba ngu-50 aphezulu.
Yiqiniso, namhlanje ungathenga i-iPod nge-128 GB yesitoreji, okuyinto isikhala esanele sokugcina amafayela a-AIFF angaba ngu-640 angaxhunyiwe, aphezulu. Ngempela wangempela umculo ongafanelana ngayo kudivayisi, okungaphezulu noma okuncane ngokuhambisana nesizukulwane sokuqala se-iPod classic namafayela ekhwalithi aphansi ayatholakala ngaleso sikhathi.
Uma ushiya i-Apple ecosystem, izinto zivula ngisho nangaphezulu. Isibonelo, i-PonoPlayer ye-Neil Young yasungulwa nge-64 GB yesitoreji sangaphakathi futhi ifaka i-slot ekhadini le-microSD elikwazi ukwamukela amakhadi ayi-128 GB. Futhi ngokwemoto yomsindo, okungadingeki ukuthi ibe yinto ephathekayo njengemikhiqizo efana ne-iPod ne-PonoPlayer, i-SSD ye-TB engu-2 iyakwazi ukugcina amafayela angama-audio alalelwayo aphezulu angaphezu kuka-10,000 esikhaleni esincane esingaphansi kwekhasethi ye-cassette.
Ngamaphi Amanani Okuba Khona
Nakuba umsindo ophezulu wokukhipha isisindo esikhulu sokusetshenziswa emotweni yemoto, ithegi lentengo empeleni izoba ngaphezulu-futhi ngezinye izikhathi ephakeme kakhulu-kunamafomethi okulahlekelwa ikhwalithi ephansi. Amafayela womculo aphezulu okuxazulula aphezulu akukona nje kuphela okubiza ngaphezulu, kodwa amadivaysi okudlala nokugcina amabizayo. Isibonelo, ungasebenzisa i-iPhone yakho ukulalela umculo emotweni yakho ngokuncane kakhulu kwezindleko zepokhethi, futhi akukho nhlobo nhlobo uma i-head unit yakho isivele ine-input assistant, futhi ukufaneleka akuyona inkinga kusukela usuvele ukhona ukuthwala ifoni nxazonke.
Uma kuqhathaniswa, ukulalela umsindo omkhulu wokuxazulula imoto emotweni yakho kuzovame ukufaka ukuthengwa okungeziwe-ungacabangi ukuthi kakade unayo idivayisi ekwazi ukudlala amafayela aphezulu-nokuxazulula isikhala esitoreji esincane, t mahhala. Idivaysi yomsindo we-high resolution ingakugijima noma yikuphi kusuka ku-$ 100 kuya ku-$ 300 noma ngaphezulu, futhi ikhadi le-128 GB microSD-elikwazi ukubamba izingoma ezingaba ngu-600 noma ngaphezulu-libiza endaweni ethile endaweni engama-$ 30 kuya ku-$ 50.
Ngakolunye uhlangothi lwesilinganiso, amadivaysi alalelwayo alalelwayo adalwe ukudlala umsindo ophezulu wokuxazulula umsindo ayabiza kakhulu, futhi i-SSD enkulu ye-2 ikwazi ukubiza kalula ngaphezu kwama-$ 500. Lokhu nakanjani kuyindlela enhle, kulabo abazimisele ukuchitha imali, ikakhulukazi uma kwakhiwa i -server yemidiya yemidiya , kodwa kusengumthamo wezindleko ezinkulu.
Isikhala sesitoreji esitholakalayo kumadivayisi aphathekayo siyokhuphuka njalo, ngenkathi izindleko zehla, kodwa umbuzo wokuphatheka okuhambisana nekhwalithi kumsindo wemoto uzohlala.
