MP3 kuya M4R Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyiguqula kanjani i-MP3 yomsindo ibe yi-M4R ngaphandle kokulahlekelwa ukhwalithi?

Layisha phezulu ihele MP3 futhi umguquli ukhetha i M4R codec ne-bitrate ukufana nomsuka. Ukungabi nalutho M4R (WAV / FLAC / ALAC) ugcina yonke isampula nge-bit-identical; ukungabi nalutho M4R (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. I-payload yi-AAC, ejwayelekile ifinyelela kumasekhondi angama-40, okungukuthi umsindo ophakathi nendawo iOS uzowuvuma.

Ingabe ukushintsha MP3 kuya ku M4R kuyingxenye yesithathu yokucindezela okulahlekile?

Yebo, futhi kufanelekile ukuhlela. Izifomethi zombili ziyi-lossy, ngakho-ke i-M4R 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-M4R kusuka kulo kunciphisa ukudluliswa okuphindiwe ngokuphelele.

Yini i-bitrate ezoba yihele elitholakele M4R lisebenzisa?

Iphutha lingu-192 kbps ku-lossy M4R; dlula-nge-lossless M4R. 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 M4R kuzonciphisa ukhwalithi yomsindo wami?

Uma MP3 ilahlekelwa yinto futhi M4R ayilahlekelwanga (isibonelo MP3 → WAV), M4R ayingcono kuna MP3 — awukwazi ukubuyisela imininingwane elahlekile. Uma MP3 ilahlekelwa yinto futhi M4R ayilahlekelwanga, M4R i-codec icindezela kabusha; ku-192 kbps imiphumela icacile kuningi kwezithameli.

Ingabe i-MP3 kuya ku-M4R iguqula igcina ID3 / metadata tags?

Zonke izinhloso ezijwayelekile (MP3, AAC, FLAC, OGG) ziphatha iziphawuli kahle; i-WAV emnyama ayisebenzi. M4R yi-iPhone ringtone — ifayela elijwayelekile le-AAC ebhokisini le-MP4 nesiqephu esishintshiwe ukuze i-iTunes ifile njenge-tone.

Ingabe ngingakwazi ukushintsha amahele amakhulu MP3 ku M4R?

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-M4R izogcina isilinganiso esifanayo sesampula njenge-MP3?

Ngokungajwayelekile yebo — 48 kHz MP3 ihlala 48 kHz ku M4R. 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 M4R?

Yebo — i-loudness-normalize option ifaka i-ITU-R BS.1770 / EBU R128 normalization ku-M4R, idinga -14 LUFS (isilinganiso sokusakaza) noma -16 LUFS (isilinganiso sepodcast). Kuhle uma uhlela ama-tracks amastered kuma-levels ahlukene.

Ingabe M4R 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-M4R codec elungele i-hardware yakho efanele.
