MP2 kuya MP3 Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyiguqula kanjani i-MP2 yomsindo ibe yi-MP3 ngaphandle kokulahlekelwa ukhwalithi?

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

Ingabe ukushintsha MP2 kuya ku MP3 kuyingxenye yesithathu yokucindezela okulahlekile?

Yebo, futhi kufanelekile ukuhlela. Izifomethi zombili ziyi-lossy, ngakho-ke i-MP3 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, ukukopisha i-MP3 kusuka kulo kunciphisa ukudluliswa okuphindiwe ngokuphelele.

Ukuxuba okuphansi kusetshenziswa izilinganiso ezijwayelekile ukuze umhlangano we-channel ephakathi uhlale ucacile futhi izingqimba zixhunywe ku-level ephansi. Noma yini esekelwe ku-channel ehlukile ihamba lapho lokhu kwenziwa. I-MP3 ihlukaniswe ngokukhethekile yi-AAC ne-Opus nganoma yisiphi isivinini se-bit, ingagcina ngaphezulu kwama-channels amabili ngokunembile, futhi ihlala ifaka ukulibazisa okuncane kwe-encoder.

Yini i-bitrate ezoba yihele elitholakele MP3 lisebenzisa?

Iphutha lingu-192 kbps ku-lossy MP3; dlula-nge-lossless MP3. Yisuse ku-320 kbps ku-audiophile noma ku-96 kbps ku-voice / podcast. Ukhetho lushintsha ubukhulu behele ku-audible fidelity; ngaphansi kwe-96 kbps i-lossy artifacts ibonakale kumculo.

Ingabe ukudlula kusuka ku MP2 kuya ku MP3 kuzonciphisa ukhwalithi yomsindo wami?

Uma MP2 ilahlekelwa yinto futhi MP3 ayilahlekelwanga (isibonelo MP3 → WAV), MP3 ayingcono kuna MP2 — awukwazi ukubuyisela imininingwane elahlekile. Uma MP2 ilahlekelwa yinto futhi MP3 ayilahlekelwanga, MP3 i-codec icindezela kabusha; ku-192 kbps imiphumela icacile kuningi kwezithameli.

Ingabe i-MP2 kuya ku-MP3 iguqula igcina ID3 / metadata tags?

Yebo — isisihloko, umculi, i-album, unyaka, inani le-track, kanye ne-album art zifundwa kusuka ku MP2 ibhokisi futhi zibhalwe ku MP3 ibhokisi lapho ifomu lixhasa iziphawuli. Zonke izinhloso ezijwayelekile (MP3, AAC, FLAC, OGG) ziphatha iziphawuli kahle; i-WAV emnyama ayisebenzi. MP3 yi MPEG-1 Audio Layer III, eqediwe ngo-1993, futhi ikhona ifomethi yomsindo ekwazi ukuconywa ngokugcwele.

Ingabe ngingakwazi ukushintsha amahele amakhulu MP2 ku MP3?

Yebo - khipha isibaya se MP2 amafayela ngaphakathi futhi sizoziphatha ngokuhambisana. I-Premium inemisebenzi eminingi ehambisanayo futhi akukho lutho oluphezulu lwesayizi yefayela ngalinye, ngakho-ke i-500-file batch iqedela imizuzu endaweni yamahora angama-10.

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

Ngokungajwayelekile yebo — 48 kHz MP2 ihlala 48 kHz ku MP3. Uma ufuna ukusatshalaliswa ngezansi ukuze kusebenze (96 kHz → 44.1 kHz ukuthwebula i-CD), isampula-rate option ifaka ukusatshalaliswa okusezingeni eliphezulu kulowo mkhawulo wokucofoza.

Ingabe ngikwazi ukushintsha umsindo uma ngiguqula MP2 kuya ku MP3?

Yebo — i-loudness-normalize option ifaka i-ITU-R BS.1770 / EBU R128 normalization ku-MP3, idinga -14 LUFS (isilinganiso sokusakaza) noma -16 LUFS (isilinganiso sepodcast). Kuhle uma uhlela ama-tracks amastered kuma-levels ahlukene.

Ingabe MP3 yami izodlala ku-car stereo, iPod, ne-Sonos?

MP3

Amafayela e-MP3 asebenzisa ukucindezela okulahlekile ukunciphisa usayizi wefayela ngenkathi kugcinwa ikhwalithi yomsindo eyamukelekayo kubalaleli abaningi.
