M4A kuya OGG Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani umsindo M4A ube OGG ngaphandle kokulahlekelwa ukhwalithi?

Layisha phezulu ihele M4A futhi umguquli ukhetha OGG i-codec / i-bitrate ehambisana neprofayili yomsuka. I-lossless OGG (WAV / FLAC / ALAC) igcina yonke isampula ngokugcwele; i-lossy OGG (MP3 / AAC / OGG / Opus) iphutha liyi-192 kbps ecacile kakhulu kunoma iyiphi ingxenye yomculo. M4A igcina i-AAC emibonweni eminingi, noma i-Apple Lossless (ALAC) uma ivela ku-lossless rip. I-Vorbis ngaphakathi kwe-OGG ilahlekile futhi isebenzisa i-bitrate eguqukayo ngokuzenzakalela, ngakho-ke ukhwalithi ibekwe njengezinga ngaphandle kwe-kbps eqinile.

Ingabe ukushintsha M4A kuya ku OGG kuyingxenye yesithathu yokucindezela okulahlekile?

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

Kungani ezinye ze M4A zefayela lami zingaguqulwa?

DRM. Iqoqo elincane lamafayela M4A libhalwe ngokufihlakele yisitolo noma isofthiwe eyenza, futhi umsindo obhalwe ngokufihlakele awukwazi ukukhishwa yinoma iyiphi i-convertor. Noma yini oyidingayo, orekhodiwe, noma othengiswe ngaphandle kokuvikelwa uguqulwa ngokuvamile; ukuthengiswa kwelayisense akuzokwenza. M4A ifihla izinto ezimbili ezihlukile kakhulu emuva kolunye ubanzi - lossy AAC kanye lossless ALAC - futhi hhayi-Apple hardware usizo akulingani.

Ingabe i-OGG izodlala emoto yami noma ku-hardware edala?

Ngokuvamile akunjalo. M4A i-decoded yinoma yini, kufaka phakathi izimoto eziphezulu nezidlali ezikhulu; OGG idinga isofthiwe eyazi i-codec, esizohlala i-hardware ehlala ikhona. Uma indawo esiya kuyo imoto ye-stereo noma umdlali ophathekayo, lokhu kuyisinqumo esiqinile sokuhlala ku M4A. OGG inezinsizakusebenza ezincane — amastereo wemoto, ama-iPods adala kanye nama-TV amaningi ngeke abone ifayela ngaso sonke isikhathi.

Ihele OGG liphele nini nge-bitrate?

Iphutha 192 kbps ku OGG olahlekelwayo; dlula-nge- OGG ongalahlekelwayo. Nciphisa ku 320 kbps uma ufuna ubukhulu obuphezulu bokungathembeki okulahlekile, 128 kbps ku-podcast yokusabalalisa obukhulu-bulinganiselwe, noma 96 kbps ku-voice-only sources lapho ifayela elincane libalulekile kunemininingwane yestudio.

Ingabe ukusuka ku M4A kuya ku OGG kuzonciphisa kakhulu izinga lami lomsindo?

Uma M4A ilahlekelwa (MP3, AAC) futhi OGG ayilahlekelwanga (WAV, FLAC), OGG ayingcono kuna M4A — awukwazi ukubuyisela imininingwane elahlekile yi-M4A codec elahlekile. Uma M4A ayilahlekelwanga futhi OGG ilahlekelwa, cabanga ukuthi i-OGG encoder izocindezela futhi; ku-192 kbps ilahlekelwa ayikwazi ukubonwa yimilomo eminingi.

Ingabe i-M4A kuya ku-OGG igcina amathegi we-ID3 / metadata?

Yebo — isihloko, umculi, i-album, unyaka, inani le-track, i-album art, BPM, ukuphindeka-kwe-gain kufundeka kusuka ku M4A ibhokisi futhi kubhalwe kuma-fields alinganayo ku OGG ibhokisi. ID3v2 (MP3), amazwana we-Vorbis (OGG, FLAC), ama-MP4 atoms (AAC, M4A), RIFF INFO (WAV), ama-iXML chunks wonke ama-maps ngokuhlanzekile. OGG yi-Xiph.Org container, ehlala igcina umsindo we-Vorbis, yakhiwa ngo-2000 njengenye indlela engavunyelwanga ye-MP3.

Ingabe ngingenza ukuguqulwa kwekhulu le M4A amafayela abe OGG?

Yebo — susa isibaya se M4A 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 amahlanu. Ukwakhiwa kwefolda kugcinwa kwi-ZIP yesingeniso.

Ingabe i-OGG izogcina isilinganiso esifanayo sesampula njenge-M4A?

Ngokungagqibekanga yebo (a 48 kHz M4A ikhiqiza 48 kHz OGG, a 44.1 kHz M4A ikhiqiza 44.1 kHz OGG). Ukusebenza kahle okuthile — isibonelo, ukusatshalaliswa kwe-96 kHz studio masters kuya ku-44.1 kHz OGG ukushaya i-CD, noma ukusatshalaliswa kwe-22 kHz voicemail kuya ku-44.1 kHz OGG — isilinganiso sesampula esiphansi sifaka ukusatshalaliswa kabusha kwekhwalithi ephezulu ye-SOX-style.

Ingabe ngizolungisa umsindo ku-M4A kuya ku-OGG?

Yebo — ukhetho lokujwayelekile-lokujwayelekile lufaka ITU-R BS.1770 / EBU R128 ukujwayelekile ku OGG kuphuma, libhekisa ku -14 LUFS (isizinda sokushayela) noma -16 LUFS (isizinda sepodcast) noma inani elijwayelekile. Lisetshenziswa uma liguqula amabhayisikobho ngezinga lokuphatha elihlukile ku OGG dlala.

Ingabe i-OGG izodlala ku-stereo yemoto yami / iPod / Sonos / isikhulumi se-Bluetooth?

I-MP3 idlala ngokugcwele kuwo wonke amadivayisi ayenziwe eminyakeni edlule engu-20. I-AAC idlala ku-Apple, ku-Android, ku-Sonos, nama-stereo emoto yamanje. I-FLAC idlala ku-Sonos ne-Android edlule, ingcono kakhulu kuma-iPods adala. I-WAV idlala kuwo wonke amadivayisi kodwa ifayela likhulu. I-idivayisi-yesihluthulelo sokukhuphuka ikhetha i-OGG codec ephephile ye-platform oyicacisile. I-OGG Vorbis ishaya i-MP3 nge-bitrate elinganayo futhi ayihambisani nezindleko zokugunyazwa, ngakho-ke ama-engine wemidlalo kanye nesofthiwe yomthombo ovulekile yasebenzisana nayo.

Ingabe ihele lami M4A liyimfihlo ngesikhathi sokuguqulwa?

Yebo — amafayela alayishwe phezulu M4A aphathwa ngabasebenzi abahlukanisiwe futhi asuswa emizuzwini. Asikwazi ukudlala, ukugcina, noma ukuhlanganisa okuqukethwe kwesandi. Ipayipi lisebenza ngehardware esilawula ngayo kusukela ekuqaleni kuya kukuphela; akukho inkonzo yeqembu lesithathu ethola ifayela lakho.

M4A

I-M4A ifomethi yefayela lomsindo ehlobene eduze ne-MP4. Inikeza ukucindezelwa komsindo kwekhwalithi ephezulu ngokusekelwa kwemethadatha, okuyenza ifanelekele izinhlelo zokusebenza ezihlukahlukene.
