MP2 ukuba MP3 Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-MP2 yesandi ibe yi-MP3 ngaphandle kokulahlekelwa umgangatho?

Layisha phezulu ifayili MP2 kwaye umguquli ukhetha i MP3 codec ne-bitrate ukuhambelana nomcebo. Ukungabikho kolahleko MP3 (WAV / FLAC / ALAC) ugcina yonke isampuli nge-bit-identical; ukungabikho kolahleko MP3 (MP3 / AAC / OGG / Opus) okumiselweyo ku 192 kbps ebonisa ngokucacileyo kwiinwele ezininzi. 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.

Ingaba ukutshintsha MP2 ukuya ku MP3 kujikelezo lwesibini lokucinezela 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 isiphumo sihlala sicacile kubaninzi bokuziva. Ukuba une master engalahleki naphi na, ukukopela i MP3 ukusuka apho endaweni yoko ikhusela i pass kabini ngokupheleleyo.

Ndingayiphawula i MP3 ngeenkcukacha zomculi ne-albham?

Ewe, kwaye yimpumelelo epheleleyo ngaphezulu kwe MP2, eyona ingekho naphi na ethembekileyo ukugcina nayiphi na. MP3 ithatha isihloko, 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.

Ithini into ebangela ukuba i-multichannel yesandi iguqulwe kwi MP2 ukuya kwi MP3?

Ijika ezantsi kwi-stereo, kuba MP3 ayinayo indlela esebenzayo ye-multichannel. Ukudibanisa ezantsi kusetyenziswa izilinganisi eziqhelekileyo ukuze unxibelelwano lwe-center-channel luhlale lucacileyo kwaye izijikelezi-ndawo zidityanisiwe kwinqanaba eliphantsi. Nantoni na exhomekeke kukubeka isiqhagamshelanisi esikhethekileyo iphela xa oku kwenzeka. MP3 igqityiwe nge AAC ne Opus kwinqanaba ngalinye le-bitrate, ayikwazi ukugcina ngaphezulu kweendawo ezimbini eziluncedo, kwaye ihlala idibanisa ulibaziso oluncinci lwe-encoder.

I-MP3 ifayili ephumayo izakusebenzisa i-bitrate enjani?

Okumiselweyo yi 192 kbps ye-lossy MP3; igqityiwe-kwi-lossless MP3. Nciphisa kwi 320 kbps ye-audiophile okanye 96 kbps yelizwi/podcast. Ukhetho lutshintshiselana ngobungakanani befayili ngokuchasene nobuxoki obunokulungiswa; ngaphantsi kwe-96 kbps i-lossy artifacts ibonakala kwingoma.

Ingaba ukutshintsha ukusuka ku MP2 ukuya ku MP3 kuya kunyusa ubunjani besandi sam?

Ukuba MP2 ilahlekile kwaye MP3 ayilahleki (umzekelo MP3 → WAV), i MP3 ayingcono kune MP2 — awunakubuyisela ulwazi olusele lulahlekile. Ukuba MP2 ayilahleki kwaye MP3 ilahlekile, i MP3 codec iphinda icinezele; kwi-192 kbps isiphumo sicacile kumxholo omkhulu.

Ingaba i-MP2 ukuya kwi-MP3 igcina i-ID3 / i-metadata tags?

Ewe — isihloko, umculi, i-albham, unyaka, inani lengoma, kunye nemifanekiso ye-albham ifundwa kwi MP2 isiqulathi seefayili kwaye ibhalwe kwi MP3 isiqulathi seefayili apho ifomati ixhasa iithagi. Zonke iziseko eziqhelekileyo (MP3, AAC, FLAC, OGG) ziphatha ii-tags kakuhle; i-WAV egqityiweyo ayisebenzi. I-MP3 yi-MPEG-1 Umphezulu Wosandi III, egqityiwe ngo-1993, kwaye ihlala i-format yesandi ekwazi ukucoda ngokupheleleyo ekhoyo.

Ndingaguqula izigidi zeefayili MP2 zibe MP3?

Ewe - susa isiqulathi seefayili se MP2 ngaphakathi kwaye siza kuziqhubekekisa ngokuthe tye. I-Premium inemisebenzi ethe tye eninzi kwaye akukho bukhulu befayili nganye obuphezulu, ngoko ke i-500-file batch igqiba kwimizuzu kunokuba iphele kwimizuzu emininzi.

Ingaba i-MP3 iya kugcina inqanaba lesampuli elifanayo njenge-MP2?

Ngokungagqibekanga ewe — 48 kHz MP2 ihlala i-48 kHz kwi MP3. Ukuba ufuna ukunyusa isampuli ukuze ihambelane (96 kHz → 44.1 kHz yokushicilela i-CD), ukhetho lwesampuli-yexabiso lisebenzisa ukuphinda uthathe isampuli esezingeni eliphezulu kwindlela efanayo yokugqitha kwekhowudi.

Ndingazilungisa njani i-loudness xa ndiguqula i-MP2 ibe yi-MP3?

Ewe - ukhetho lokwenza lusebenze ngokuqhelekileyo ubukhulu busebenzisa ukwenziwa ngokuqhelekileyo kwe-ITU-R BS.1770 / EBU R128 kwi MP3, ukubeka injongo kwi-LUFS -14 (isiqhelo sokusasaza) okanye kwi-LUFS -16 (isiqhelo sepodcast). Isetyenziswa xa kudityaniswa iingoma ezilawulwa kumanqanaba ahlukeneyo.

Ingaba ifayili yam MP2 ifihlakeleyo ngexesha lokuguqulwa ukuya kwi MP3?

Ewe — iifayile ezilayishwe phezulu MP2 ziqhubekekiswa kubasebenzi abakhethekileyo kwaye zicinywe kwimizuzu. Asiyi kudlala kwakhona, sigcine ixesha elide, okanye sisebenzise imixholo yesandi. Ifestile yokugcina epheleleyo ikwi /privacy/.
