MP2 ukuba MP3 Imibuzo Ebuzwa Rhoqo Ngokuguqula

Yintoni eyenza i-MP2 ukuya kwi-MP3 iguquli sesandi?

It re-encodes a MP2 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-MP2 ukuya kwi-MP3 kunokuphinda kuphindeke?

Ungaguqula i-MP3 kwakhona kwi-MP2 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-MP2 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 MP2 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. MP2 ilahlekile kodwa isebenzisa ibanki yecebo lokucoca ulwelo elilula kune MP3, eqhelekileyo isebenza kwi 192 ukuya kwi 384 kbps. 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 MP2, 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 MP2 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 MP2 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.

Ewe. Nqumle okanye ukhethe iifayile ezininzi ze MP2 kwifayili enye yokulayisha - umguquli uqhubekeka nazo ngokuthe tye kwaye ubuyisele i-ZIP yeziphumo ze MP3. Akukho mfuneko yokuphinda uqhubekeke inkqubo yefayili nganye.

MP2

MP2 is the audio layer that predates MP3, still used in digital radio and broadcast because decoding is cheap and robust.

MP3

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