MP3 kuya MP2 Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani umsindo MP3 ube MP2 ngaphandle kokulahlekelwa ukhwalithi?

Layisha phezulu ihele MP3 futhi umguquli ukhetha i-MP2 codec ne-bitrate ukufana nomsuka. Ukungabi naphutha MP2 (WAV / FLAC / ALAC) ugcina yonke isampula nge-bit-identical; ukungabi nalutho MP2 (MP3 / AAC / OGG / Opus) kumiswa ku-192 kbps okucacile kuma-earphones amaningi. MP3 ilahlekelwa: imodeli ye psychoacoustic isusa iziqongo ezingezona ezivamile, ezivame ukuba ngu-128 kuya ku-320 kbps. MP2 ilahlekelwa yinto kodwa isebenzisa isihlungi esilula kunaso iMP3, isebenza nge 192 kuya ku 384 kbps.

Ingabe ukushintsha MP3 kuya ku MP2 kuyingxenye yesithathu yokucindezela okulahlekile?

Yebo, futhi kufanelekile ukuhlela. Izifomethi zombili ziyi-lossy, ngakho-ke i-MP2 encoder isebenza kusuka kumsindo osele udlulele engxenyeni eyodwa ye-psychoacoustic, futhi iziphakamiso zayo zihlanganisa isiqephu sokuqala. Ku-192 kbps noma ngaphezulu, imiphumela ihlala icacile kakhulu. Uma une-lossless master nganoma yikuphi, uku-encoding i-MP2 kusuka kulo kunciphisa ukudlula okuphindiwe ngokuphelele.

Ingabe izihloko zengoma yami nesithombe se-albhamu sizohlala isikhathi eside uma ngishintsha MP3 kuya ku MP2?

Akulungile. MP3 ifaka i-metadata efanele, kodwa MP2 ayinaso isikhala esijwayelekile somuntu oculi, i-album, inani le-track noma umhlobiso we-cover, ngakho-ke amathegi asuswa ngaphandle kokulahleka. Gcina i-MP3 njengekhophi elabelwe, noma uphinde ubeke i-tag ngemuva ngethuluzi njenge Mp3tag noma MusicBrainz Picard. I-MP2 idinga i-bitrate engaphezulu kune-MP3 noma i-AAC ukuze ibe nekhwalithi efanayo futhi ayiziwa kusoftware eminingi yomsebenzisi.

Yini i-bitrate ongayisebenzisa ihele elivela ku-MP2?

Iphutha ngu-192 kbps ku MP2 olahlekelwayo; ukudluliswa-kwe- MP2 okungalahleki. Nciphisa ku-320 kbps ku-audiophile noma ku-96 kbps ku-voice / podcast. Ukhetho lushintsha ubukhulu behele ku-audible fidelity; ngaphansi kuka-96 kbps olahlekelwayo, ama-artefacts abonakala emculo.

Ingabe ukusuka ku MP3 kuya ku MP2 kuzonciphisa ubunjani bomsindo wami?

Uma MP3 ilahlekelwa futhi MP2 ayilahleki (isibonelo MP3 → WAV), MP2 ayingcono kuna MP3 — awukwazi ukubuyisela imininingwane elahlekile. Uma MP3 ilahlekelwa futhi MP2 ayilahleki, i-MP2 codec icindezela futhi; ku-192 kbps imiphumela icacile kunoma iyiphi ingxenye.

Ingabe i-MP3 kuya ku-MP2 igcina amathegi we-ID3 / metadata?

Yebo — isihloko, umculi, i-album, unyaka, inani lesiqalo, nesithombe se-album zifundwa kusuka ku MP3 isitoreji futhi zibhalwe ku MP2 isitoreji lapho ifomu lixhasa amathegi. Zonke izimo ezijwayelekile (MP3, AAC, FLAC, OGG) ziphatha amathegi kahle; i-WAV engaqondakali ayisebenzi. MP2 yi MPEG-1 Audio Layer II, i-layer edlule i-MP3 futhi yabe yi-audio standard ye-DVB ne-DAB broadcasting.

Ingabe ngingenza i-batch yokuguqula amahele angama-MP3 abe MP2?

Yebo — susa isibaya se MP3 amafayela ngaphakathi futhi sizoziphatha ngokufanayo. I-Premium inemisebenzi eminingi efana ne-parallel futhi akukho lutho oluphezulu lwesayizi yefayela ngalinye, ngakho-ke i-500-file batch iphele ngemizuzu endaweni yamahora angama-10.

Ingabe i-MP2 izogcina isilinganiso esifanayo sesampula njenge-MP3?

Ngephutha yebo — 48 kHz MP3 ihlala 48 kHz ku MP2. Uma ufuna ukusatshalaliswa ngezansi ukuze kusebenze (96 kHz → 44.1 kHz ukushaya i-CD), isinqumo sesampula-sayizi sifaka ukusatshalaliswa okusezingeni eliphezulu kuleyo ngxenye yokungenisa ikhodi.

Ingabe ngizolungisa umsindo uma ngiguqula MP3 ku MP2?

Yebo — ukhetho lokujwayelekile-lokujwayelekile lufaka ITU-R BS.1770 / EBU R128 ukujwayelekile ku MP2, lubeka inhloso -14 LUFS (isizinda sokushayela) noma -16 LUFS (isizinda sepodcast). Kuhle uma kuhlanganiswa amabhayisikobho aqeqeshiwe ezingeni ezahlukene.

Ingabe MP2 yami izodlala ku-car stereo, iPod, ne-Sonos?

MP3 idlala kuwo wonke amadivayisi. I-AAC idlala ku-Apple, ku-Android, ne-Sonos. I-FLAC idlala ku-Sonos ne-Android kodwa ayikho ku-iPods edlule. I-WAV idlala kuwo wonke amadivayisi kodwa inamandla amakhulu. Imenyu yokudonsa yedivayisi ethuthukisiwe ikhetha i-MP2 codec elungele i-hardware yakho efanele. MP2 inamandla amakhulu kakhulu ukuxazulula amaphutha ancane futhi ibiza kakhulu ukuwususa, ngakho-ke izintambo zokusakaza zihlala kuyo isikhathi eside ngemuva kokufika kweMP3.

Ingabe ihele lami MP3 liyimfihlo ngesikhathi sokuguqulwa ku MP2?

Yebo — amafayela alayishwe phezulu MP3 aqhubekelwa phambili emisebenzini ehlukanisiwe futhi acishwe ngaphakathi kwemizuzu. Asikwazi ukudlala emuva, ukugcina isikhathi eside, noma ukuhlanganisa okuqukethwe kwesandi. Ifasitela lokugcinwa okuphelele likhona ku /privacy/.

Ingabe kuthatha isikhathi esingakanani ukushintsha ihora le-MP3 libe MP2?

I-codec efanayo iphinde i-mux: 10 kuya ku-30 imizuzwana. Yenza kabusha i-codec eyahlukileyo: 10 kuya ku-20% yesikhathi somthombo, ngakho-ke ihora MP3 → MP2 liphela ngemizuzu engu-6 kuya ku-12. Imisebenzi yeqembu ihamba ngokufanayo phakathi kwabasebenzayo ukuze kube nokukhawulela okuningi.
