AIFF ukuba AAC Imibuzo Ebuzwa Rhoqo Ngokuguqula

Yintoni eyenza i-AIFF ukuya kwi-AAC iguquli sesandi?

AIFF yisandi engalahlekiyo; AAC ilahlekile. Umguquli uphinde ubhale ikhowudi ye-waveform kwi-bitrate emiselweyo. Isiphumo sincinci kakhulu kodwa sisusa ezinye iziqulatho zesantya esingalunganga - ngokuqhelekileyo zicacile kwi-192 kbps+.

Yintoni i-bitrate endingakhetha kuyo i-AAC?

320 kbps yomgangatho wovimba, 256 kbps yokufunda ngokucacileyo kwisandi esikhulu, 192 kbps yokusasaza, 128 kbps xa ubungakanani befayile bulawula. Ngaphantsi kwe 96 kbps iindidi zezinto zibonakala kwizinto eziqulethe i-percussive.

Ingaba ukuguqulwa kwe-AIFF ukuya kwi-AAC kunokuphinda kuphindeke?

Ungaguqula i-AAC kwakhona kwi-AIFF kule ndawo. Ukuba nayiphi na ifomati ebandakanyiweyo ilahlekile, i-round-trip ayizukuba yi-bit-perfect nakuba ibonakalayo okanye icacile.

Ingaba iAAC iya kuba ncinci kangakanani na kune-AIFF yam?

Ngokuqhelekileyo 5-10x ngaphantsi kwemifanekiso, 5-15x ngaphantsi kwesandi. Uthelekiso oluchanekileyo luxhomekeke kumphakamo womgangatho okhethiweyo kunye nento equlethe - imifanekiso ethe tyaba-emnyama nesandi esitshixiweyo sicinezela kakhulu kunemifanekiso ethe nkcukacha okanye iingoma zesandi ezixakekileyo.

Ingaba ndilahlekelwe yintoni ngokuguqula AIFF ukuya ku AAC?

Ezinye, kwaye zihlala zikhona - le yindawo enye apho ulwazi luza kuthuthwa khona. AIFF igcina yonke imilinganiselo ngokuchanekileyo; AAC isusa into eyenza ukuba imodeli yepsychoacoustic ilindele ukuba awuzukuyiva. Kwi-192 kbps nangaphezulu, le mbono ilungile ngokwaneleyo ukuba icacile kwizinto ezininzi kunye neezixhobo ezininzi. Gcina i AIFF njengenkosi yakho, kuba awunakubuyela kuyo ukusuka kwi AAC. I-AIFF igcina i-PCM engacinezelwanga encinci-ephakathi — i-Apple-side elinganayo ne-WAV, nge-bit-per-bit fidelity efanayo. I-AAC ilahlekile kodwa isebenza kakuhle kune-MP3, kwaye iphatha ukuya kuthi ga kwi-48 yeendlela eziqhelekileyo kunokuba ifakwe ibhotile kuyilo lwestereo.

Yintoni na i-AAC ifayili?

Uqhubo olumnyama lwee-frames zesandi ezikhowudiweyo ngaphandle komgcini ojikelezayo. Le yisizathu sokuba iifayile ezimbini AAC zingadityaniswa ngokulula ngokubeka enye emva kwenye, kwaye ngokufanayo kutheni konke okungaphezulu kwesandi - ubude, ukukhangela isalathisi, ubugcisa bokuqubha - kufuneka kuboshwe njenge konvensi kunokuba ibe yinxalenye yefomati, ngoko umdlali kufuneka ufunde ifayile yonke usebenze ukuba ide kangakanani. Kumalunga nento elula ebizwa ngokuba yifayile yesandi, eyiyo isizathu sokuba ivela ngaphakathi kwezinye iziqulathi-zifayili rhoqo kuneyo.

Ingaba AIFF ihamba phambili?

Iphumelele ngokucokisekileyo kunokuba itshintshwe. Yonke into edlala ngayo namhlanje izakuqhubeka idlala - iifomati aziyikuyeka ukusebenza - kodwa abakhowudi abatsha kunye nezixhobo ezintsha eziqhubekayo ezimiselweyo ukubuyisela, ngoko ke umbuzo osemthethweni kukuba ngaba ezifayile kufuneka zivuleke kwinto ethengiweyo iminyaka elishumi ukusukela ngoku. Nantoni na enikezelwe okanye eshicilelwe, uguqulelo lukhuselo olulula. Kwincwadi yobuqu edlala kakuhle, ukuyishiya iphela yiimpendulo ekhuselekileyo. I-AIFF ikhulu njenge-WAV enesixhaso esibi ngaphandle kwehlabathi le-Apple, ngoko ke kukhetho olubi lokusasaza.

Ingaba AIFF ikhululekile ukuyisebenzisa nokusasaza?

Ewe, ngaphandle kweemeko ezifanele ukukhathazeka ngazo. Ukhankaso luza kufumaneka, wonke umntu angasebenzisa ikhowudi okanye ikhowudi esuka kwikhowudi ngaphandle kokubuza okanye ukuhlawula, kwaye akukho mntu unokuguqula ezi zinto emva - nto leyo eyenza ukuba ivele kwi open- source tooling, kwi engines yemidlalo naphi na apho ilayisensi yokuxoxa ibulala iprojekthi. Ukutshintsha kude nayo akuyi kubuyisela oko; iifayile ozinayo zihlala zisetyenziswa ngokuchanekileyo njengoko zazi.

Ubani ochaza AAC?

Ilungu eliqhelekileyo leqela lenkampani, elininzi lesizathu sokuba likho kuyo yonke indawo. AAC yacaciswa ngenkqubo yehlabathi eyenza i-MPEG eqhelekileyo, ngoko abasasazi, abavelisi befowuni, abathengisi besikhangeli kunye nenkonzo yosasazo zonke zazisa uxwebhu olufanayo endaweni yokunika ilayisensi iimveliso zabanye. Isizathu esisebenzayo sibuhlungu kwaye siluncedo: i AAC eyenziwe ngesixhobo esinye ikhupha ikhowudi ngokufanayo kwinye, kwaye akukho mthengisi oxhaswa ngazo ezinokuthi zibuyiselwe. I-AAC yiNkqubo yoKhuseleko lwesandi esiPhambili, emiselwe ngo-1997 njenge-MPEG-2 Inxalenye ye-7 kwaye icwangciswe ngokucacileyo ukubuyisela i-MP3.

Ingaba kukho umda wobungakanani befayili xa uguqula i-AIFF ibe yi-AAC?

Ulayisho phezulu olungaziwayo luphelelwe lixesha ngokumiselweyo; i-akhawunti ebhalisiweyo ekhululekileyo ifumana umda ophezulu, kwaye i-akhawunti ye-Pro ayinalo umda wefayili nganye. Inkumbulo yesikhangeli sihlala siyimfuneko yothintelo ixesha elide phambi kokuba umda wethu we-server-side uqale.

Ndingaguqula iifayili ezininzi ze-AIFF zibe yi-AAC ngaxeshanye?

Ewe. Nqumle okanye ukhethe iifayile ezininzi ze AIFF kwifayili enye yokulayisha - umguquli uqhubekeka nazo ngokuthe tye kwaye ubuyisele i-ZIP yeziphumo ze AAC. Akukho mfuneko yokuphinda uqhubekeke inkqubo yefayili nganye.

Ithini into eyenza ukuba i-AIFF yam ifile iguqulwe?

Iifayili ezilayishwe phezulu kunye ne-AAC iimveliso zicinywa ngokuzenzekelayo emva kwefestile efutshane yokugcina. Asiyi kujonga, sizonwabele, okanye siqeqeshe kwiifayili zomsebenzisi. Ikhonkco lokulayisha ezantsi ngokuthe ngqo limiselwe ixesha kwaye lidityaniswe kwintlanganiso yakho.
