I-AAC ne-MP3: I-ITunes Test Quality Sound Test

Yikuphi Ukubhalisa Okuhle Kakhulu Kumlaleli Ophakathi?

Iningi lama-audiophiles-abantu abanokuzwa okuphezulu futhi abazisa kakhulu izinga eliphezulu elizwakalayo-livame ukuzonda i-MP3 namanye amafomethi omsindo wedijithali ngoba amafomethi asebenzisa ukucindezela okususa ulwazi kumafayili edijithali ukugcina isikhala. Kuyiqiniso ukuthi lezi zakhiwo zisusa ulwazi, kodwa abalaleli abaningi abajwayelekile abakwazi ukuzwa ukulahleka. Njengomlaleli ophakathi nomthengi womculo, ngenza uhlolo ukuze nginqume ukuthi ifomethi eyodwa iyenze enye eyenziwe ngekhwalithi ezwakalayo.

Kukholelwa kakhulu ukuthi amafayela we- AAC -ifomethi yomculo ekhethwa iTunes kanye ne-iTunes Store-izwakale kangcono futhi ithatha isikhala esingaphansi kwe-MP3 yengoma efanayo. Ngibeka inkolelo ekuvivinyeni okuhlolisisayo ukukusiza ukuthi unqume ukuthi iyiphi ifomethi yefayela oyisebenzisayo izingoma kumtapo wakho we- iTunes naku-iPhone yakho ne-iPod.

Ukuqhuba ukukhishwa kwefomethi yefayili yomsindo , nginekhodi izingoma ezimbili ngezindlela ezihlukahlukene: njengezingama 128 Kbps ze-AAC nama- MP3 , njengezingama-192 Kbps AAC nama-MP3, kanye namafayela angu-256 Kbps AAC nama-MP3. Ephakeme inombolo ye-Kbps, ifayela elikhulu, kodwa ngcono ikhwalithi-okungenani inory. Kuzo zonke amafayela, ngasebenzisa i-encoder eyakhelwe iTunes.

Izihloko Zokuhlolwa

Ngesivivinyo sami, ngakhetha izingoma ezimbili: i-Sage Wild, ebizwa ngokuthi "Sage Wild," ebizwa ngokuthi i-Mountain Goats, nekhava elikhulu, elikhukhumezekile elithi "Ukushiya I-Jet Plane," ngo-Me First no-Gimme Gimmes.

"Sage Wild" igcwele pianos ezicashile kanye isiginci ngomunwe / ethathwe ngomunwe, ngokuhlabelela okuphakeme, ukuzwela.

Ngikhethe ngoba ngithemba ukuthi lezo zigaba eziyinkimbinkimbi zizoveza imininingwane eminingi ezinhlokweni ezihlukahlukene zefayela.

"Ngaphandle kokuhamba ngeJet Plane," ngakolunye uhlangothi, kuyashesha, kunomsindo, kunzima kakhulu, futhi kugcwele izigubhu eziyinkimbinkimbi. Le ngoma izethemba ngokukhombisa ububanzi obunamandla futhi yembulani ezinye izinto ezithi "i-Sage Wild" elula.

Ngasebenzisa ikhophi yami ye-CD zombili izingoma-mhlawumbe izinga eliphezulu kunazo zonke ezitholakalayo kimi-njengesisekelo sokuqala.

Nakhu engikutholile:

256 Kbps

• I-Wild Sage: Zombili izinguqulo zengoma zizwakala kahle ku-256 Kbps. Ngiyakwazi ukuzwa ngokucacile ukukhishwa kwemicu yegitala nokuphefumula kwezwi elingenakho ukuphazamiseka noma kuphi. Izinguqulo ze-MP3 ne-AAC zizwakala zifana ngokufanayo. Akukho mdlali ocacile lapha. I-MP3 version yi-1.2MB encane, noma kunjalo.
• Ukuhamba Esikebheni Se-Jet: Isimo esifanayo lapha. Ingoma izwakala kahle. Izwi licacile ngezimpawu ezicashile kanye nomqondo ogcwele wokukhanya, kodwa akuzwanga neze umsindo ohlukile.

192 Kbps

• I-Wild Sage: Le nguqulo ithokoza kancane kancane uma kuqhathaniswa ne-256 Kbps. Kodwa-ke, kusasekho umehluko ocacile phakathi kwe-AAC ne-MP3. I-MP3 cishe i-1MB encane.
• Ukuhamba Esikebheni Sezindiza: Iphethini iqinisile. Akufani ne-256 Kbps kodwa kufana phakathi kwamafomethi amabili wefayela .

128 Kbps

• Sage Wild: Ekugcineni umehluko. Kule nguqulo, inguqulo ye-AAC icacile futhi icacile kune-MP3, ehlushwa udodi oluncane kanye nokuhlangana komunye umsindo. Ubukhulu befayili bufana ncamashi, okwenza inguqulo ye-AAC ibe umqobi ocacile lapha.
• Ukuhamba Esikebheni Sezindiza: Lapha i-AAC ingcono kakhulu ekugqibeleni kwedrub. Uma kungenjalo, izingoma zizwakala ngendlela efanayo futhi zifana nosayizi ofanayo.

Isiphetho

Nakuba zikhona, ngokungangabazeki, umehluko emagagasi omsindo ala mafayela amathathu, azizwakala ngokulinganayo. Yize kungase kube khona imininingwane eminingana kuma-256 Kbps MP3, kunzima ngendlebe engafundiwe ukuqonda, futhi amafayela aphezulu kunanoma iyiphi enye inguqulo. Indawo kuphela ongase uzwe ngayo umehluko kusekhompini ephansi ye-128 Kbps, kodwa angiyincoma lawo noma kunjalo.

Ngakho-ke, enikeziwe lemiphumela yokuhlola, kubonakala sengathi ingxabano phakathi kwe-AAC ne-MP3 ingahle ibe yindaba yokunambitheka, imibono noma ibe nezindlebe ezingcono kunami.
