MP3 kuya MP2 Imibuzo Evame Ukubuzwa Yokuguqulwa

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

Layisha phezulu ihele MP3 futhi umguquli ukhetha i MP2 codec ne-bitrate ukufana nomsuka. Ukungabi nalutho MP2 (WAV / FLAC / ALAC) ugcina yonke isampula nge-bit-identical; ukungabi nalutho MP2 (MP3 / AAC / OGG / Opus) iphutha ku-192 kbps ecacile kulezi zindlebe eziningi. 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, ukukopisha i-MP2 kusuka kulo kunciphisa ukudluliswa okuphindiwe ngokuphelele.

Yini i-bitrate ezoba yihele elitholakele MP2 lisebenzisa?

Iphutha lingu-192 kbps ku-lossy MP2; dlula-nge-lossless MP2. 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 MP3 kuya ku MP2 kuzonciphisa ukhwalithi yomsindo wami?

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

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

Yebo — isisihloko, umculi, i-album, unyaka, inani le-track, kanye ne-album art zifundwa kusuka ku MP3 ibhokisi futhi zibhalwe ku MP2 ibhokisi lapho ifomu lixhasa iziphawuli. Zonke izinhloso ezijwayelekile (MP3, AAC, FLAC, OGG) ziphatha iziphawuli kahle; i-WAV emnyama ayisebenzi. MP2 yi MPEG-1 Audio Layer II, i-layer edlule i-MP3 futhi yabe yi-audio standard ye-DVB ne-DAB broadcasting.

Ingabe ngingakwazi ukushintsha amahele amakhulu MP3 ku MP2?

Yebo - khipha isibaya se MP3 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-MP2 izogcina isilinganiso esifanayo sesampula njenge-MP3?

Ngokungajwayelekile yebo — 48 kHz MP3 ihlala 48 kHz ku MP2. 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 MP3 kuya ku MP2?

Yebo — i-loudness-normalize option ifaka i-ITU-R BS.1770 / EBU R128 normalization ku-MP2, idinga -14 LUFS (isilinganiso sokusakaza) noma -16 LUFS (isilinganiso sepodcast). Kuhle uma uhlela ama-tracks amastered kuma-levels ahlukene.

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

MP3 idlala kuwo wonke amathuluzi. AAC idlala ku-Apple, ku-Android, ne-Sonos. FLAC idlala ku-Sonos ne-Android kodwa hhayi ku-iPods ezidala. WAV idlala kuwo wonke amathuluzi kodwa ikhulu. Idivayisi ethuthukisiwe-isethelwe ngaphambili ikhetha i-MP2 codec elungele i-hardware yakho efanele.
