AC3 ukuba MP3 Imibuzo Ebuzwa Rhoqo Ngokuguqula

Yintoni eyenza i-AC3 ukuya kwi-MP3 iguquli sesandi?

It re-encodes a AC3 audio file as MP3. 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-MP3 output.

Ingaba ukuguqulwa kwe-AC3 ukuya kwi-MP3 kunokuphinda kuphindeke?

Ungaguqula i-MP3 kwakhona kwi-AC3 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-AC3 ukuya kwi-MP3?

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

Ingaba ukutshintsha AC3 ukuya MP3 kukwindawo yesibini yokucinezela okulahlekileyo?

Ewe, kwaye kufanelekile ukucwangcisa. Zonke iifomati zilahlekile, ngoko ke i MP3 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 MP3 ukusuka apho endaweni yoko ikhusela i pass kabini ngokupheleleyo. AC-3 yisandi esilahlekileyo esingenasiqhagamshelanisi esininzi, sihlala siyi-5.1 kwi-384 okanye 448 kbps, nemetadata yonxibelelwano oluqhelekileyo noluphantsi koxinzelelo. I-MP3 ilahlekile: imodeli ye-psychoacoustic isusa ukuphindaphinda indlebe ayikwazi ukuqaphela, ihlala kwi-128 ukuya kwi-320 kbps.

Ndingayiphawula i MP3 ngeenkcukacha zomculi ne-albhamu?

Ewe, kwaye yinzuzo elungileyo ngaphezulu kwe AC3, eyona ingekho naphi na ethembekileyo ukugcina nayiphi na. MP3 ithatha igama, umculi, i-albham, unyaka, inani lengoma kunye nobugcisa bokuqhoboshela okufakwe kwisiqulathi seefayili, ngoko ithala leencwadi lengoma liyifaka ngokuchanekileyo ngaphandle kokuhamba ngesandla. Akukho nto ibetha iMP3 ekusebenzeni kwayo - iistereo zemoto, izixhobo zegym, iiDAPs kunye nezixhobo zekhompyutha ezineminyaka engama-20 ubudala zonke zifunda ngaphandle kwemibuzo.

Yintoni na i-MP3 ifayili?

Uqhubo olumnyama lwee-frames zesandi ezikhowudiweyo ngaphandle komgcini ojikelezayo. Le yisizathu sokuba iifayile ezimbini MP3 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.

Ithini into ebangela ukuba i-audio ekwi-multichannel iguqulwe kwi AC3 ukuya kwi MP3?

Ijika ezantsi kwi-stereo, kuba MP3 ayinayo indlela esebenzayo ye-multichannel. Ukhuphelo lwe-downmix lusebenzisa izilinganisi eziqhelekileyo ukuze unxibelelwano lwe-center-channel luhlale lucacileyo kwaye izijikelezi-mandla zixutywe kwinqanaba eliphantsi. Nantoni na exhomekeke kubekwa kwesiqhagamshelanisi esikhethekileyo siphelile xa oko kwenzeka. MP3 igqityiwe nge AAC ne Opus kwinqanaba ngalinye le-bitrate, ayikwazi ukugcina ngaphezulu kweendawo ezimbini eziluncedo, kwaye ihlala idibanisa ulibaziso oluncinci lwe-encoder.

Ingaba kukho ilayisensi edityaniswe ne AC3?

Akukho nto ofuna ukuyicinga. I-codec iquka i-patent pools, kwaye ilayisensi ibekwe ngumthumeli we-decoder - ifowuni, umkhangeli zincwadi, inkqubo yokusebenza - ixesha elide phambi kokuba ifayile ifike kuwe. Yiyo loo nto ifomati ikho kuyo yonke indawo kwihardware, kwaye kutheni i royalty- free alternatives yakhiwa naphi na. Ayitshintshanga nto malunga nokutshintsha ifayile oyinayo, kwaye kumbuzo ophilayo kuphela ukuba uthumeli i-encoder ngokwakho.

Ubani ochaza MP3?

Ilungu eliqhelekileyo leqela lenkampani, elininzi lesizathu sokuba likho kuyo yonke indawo. MP3 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 MP3 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-AC3 zibe yi-MP3 ngaxeshanye?

Ewe. Nqumle okanye ukhethe iifayile ezininzi ze AC3 kwifayili enye yokulayisha - umguquli uqhubekeka nazo ngokuthe tye kwaye ubuyisele i-ZIP yeziphumo ze MP3. Akukho mfuneko yokuphinda uqhubekeke inkqubo yefayili nganye.

MP3

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