MP3 ukuba AAC Imibuzo Ebuzwa Rhoqo Ngokuguqula

Yintoni eyenza i-MP3 ukuya kwi-AAC iguquli sesandi?

It re-encodes a MP3 audio file as AAC. Sample rate and channel count are preserved; the difference is the codec and container.

Ingaba inqanaba lesampuli kunye nobeko lwesiqhagamshelanisi ziya kugcinwa?

Ngokungagqibekanga ewe — i-stereo ihlala i-stereo, i-sample rate emiselweyo (44.1 kHz, 48 kHz, njl.njl.) idluliselwa kwi-AAC output.

Ingaba ukuguqulwa kwe-MP3 ukuya kwi-AAC kunokuphinda kuphindeke?

Ungaguqula i-AAC kwakhona kwi-MP3 kule ndawo. Ukuba nayiphi na ifomati ebandakanyiweyo ilahlekile, i-round-trip ayizukuba yi-bit-perfect nakuba ibonakalayo okanye icacile.

Yintoni umgangatho wemveliso endingalindele ukuba ndiyilindele ukusuka kwi-MP3 ukuya kwi-AAC?

Izicwangciso ezimiselweyo zijolise kwi-broadcast / umgangatho we-web - ngokubonakalayo ifana nomcebo kubabukeli abaninzi. Ukusetyenziswa kovimba, khetha ukhetho oluphezulu lomgangatho kwimimiselo yoguquli.

Ingaba ukutshintsha MP3 ukuya AAC kukwindawo yesibini yokucinezela okulahlekileyo?

Ewe, kwaye kufanelekile ukucwangcisa. Zonke iifomati zilahlekile, ngoko ke i AAC encoder isebenza kwisandi esisele sidlula kwindlela enye ye psychoacoustic, kwaye izigqibo zayo zidibanisa iseti yokuqala. Kwi 192 kbps okanye ngaphezulu impumelelo ihlala icacile kubaninzi bokuziva. Ukuba une master engalahleki naphi na, ukukopela i AAC ukusuka apho endaweni yoko ikhusela i pass kabini ngokupheleleyo. I-MP3 ilahlekile: imodeli ye-psychoacoustic isusa ukuphindaphinda indlebe ayikwazi ukuqaphela, ihlala kwi-128 ukuya kwi-320 kbps. 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.

Ezininzi zeefayili zam MP3 zavela kwiCDs - ngaba oku kubaluleke apha?

Kuphela ukuba ukukopela sele kwenzeka kabini. A MP3 okutshatywa kwi diski wacinezelwa nakweyiphi na i bitrate i ripper icwangciswe kwiminyaka edlulileyo, kwaye oko kumgangatho kwizinto zonke ezantsi - ukuguqula akukwazi ukubuyisela into i ripper eshiyekayo. Ukuba i diski ihlala kwi shelf, ukuphinda ukhuphe kwifomati engalahlekiyo nokukhowuda ukusuka apho kunika isiphumo esingcono kunanoma iyiphi ukuguqulwa kwefayile ezikhoyo. I-MP3 yi-MPEG-1 Umphezulu Wosandi III, egqityiwe ngo-1993, kwaye ihlala i-format yesandi ekwazi ukucoda ngokupheleleyo ekhoyo.

Ingaba MP3 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.

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-MP3 zibe yi-AAC ngaxeshanye?

Ewe. Nqumle okanye ukhethe iifayile ezininzi ze MP3 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-MP3 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.

MP3

Iifayile zeMP3 zisebenzisa ucinezelo olulahlekileyo ukunciphisa ubungakanani befayile ngelixa zigcina umgangatho wesandi owamkelekileyo kubaphulaphuli abaninzi.
