AIFF → OGG

Ezinye, futhi zihlala - lokhu kuyindlela eyodwa lapho ulwazi luthunyelwe khona. AIFF ligcina yonke imibiko ngokugcwele; OGG lisusa lokho imodeli ye-psychoacoustic icabanga ukuthi awukwazi ukulalela. Ku-192 kbps futhi ngaphezu kwalokho, i-prediction iyilungile ngokwanele ukubukeka kahle kuningi kwamathuluzi nangaphezulu kwamathuluzi. Gcina i-AIFF njenge-master yakho, ngoba awukwazi ukubuyela kuyo kusuka ku-OGG.

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.

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

Yebo — isihloko, umculi, i-album, unyaka, inani le-track, i-album art, BPM, ukuphindeka-kwe-gain kufundeka kusuka ku AIFF 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.

Yebo — susa isibaya se AIFF 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.

Ngokungagqibekanga yebo (a 48 kHz AIFF ikhiqiza 48 kHz OGG, a 44.1 kHz AIFF 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.

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.

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. OGG inezinsizakusebenza ezincane — amastereo wemoto, ama-iPods adala kanye nama-TV amaningi ngeke abone ifayela ngaso sonke isikhathi.

Yebo — amafayela alayishwe phezulu AIFF 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.

I-codec efanayo iphinde i-mux (isibonelo AAC ngaphakathi M4A -> AAC ngaphakathi MP4): imizuzwana engu-10-30. Ushintsho lwe-codec (isibonelo FLAC -> MP3 noma WAV -> AAC): ngokuvamile 10-20% yomthombo wesikhathi, ngakho-ke ihora AIFF -> OGG liphele ngemizuzu engu-6-12 ku-pipeline ejwayelekile.

Akukho shintsho lokufinyelela oluzenzakalelayo kwenziwa ngaphandle kokuthi ukhetho lokujwayelekile luxhunywe. Uma ukhuluma ngezinga lokushintsha, umdlali wakho wesandi noma i-media library ingasebenzisa i-ReplayGain noma ukuguqulwa kwe-track-by-track ku-playback - vala lokho futhi i-OGG izwakala ifana ne-AIFF (nge-lossless) noma ifana ngokuzizwa (nge-translucent lossy).
