Opus kuya AIFF Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiguqula kanjani umsindo Opus ube AIFF ngaphandle kokulahlekelwa ukhwalithi?

Layisha phezulu ihele Opus futhi umguquli ukhetha AIFF i-codec / i-bitrate ehambisana neprofayili yomsuka. I-lossless AIFF (WAV / FLAC / ALAC) igcina yonke isampula ngokugcwele; i-lossy AIFF (MP3 / AAC / OGG / Opus) iphutha liyi-192 kbps ecacile kakhulu kunoma iyiphi ingxenye yomculo. I-Opus iqala ngokukhuluma kusuka ku-6 kbps mono speech kuya ku-510 kbps stereo music ku-bitstream efanayo futhi ishintsha indlela ngokuzenzakalela. I-AIFF igcina i-PCM engacindezelwanga enkulu-endian — i-Apple-side elinganayo ne-WAV, nge-bit-for-bit fidelity efanayo.

Ingabe ukushintsha Opus kuya ku AIFF kuzothuthukisa ukhwalithi yomsindo?

Akunalutho, futhi kufanelekile ukuba kucace: akukho okuzokwenzeka. I Opus idlulele i-detail ngesikhathi sokuqothula kwayo okujwayelekile, futhi ukubopha okushiwo ku AIFF ongeke ulahlekelwa yilutho kugcina lokho - akukho okuningi. Ihele lithola izikhathi eziningi ezikhulu futhi lizwakala lifana. Kukhona ukunyakaza okulungile ngaphambi kokuhlela, ngoba AIFF ngeke ihlanganise isizukulwane sesithathu sezinto ezibonakalayo uma ukhipha. I-AIFF iyifomethi yokushintshana kwestudio ku-macOS, iphatha i-metadata kahle kunaleyo ye-WAV, futhi ingenisa ku-Logic ne-Pro Tools ngokushesha. I-Opus ayixhaswa yi-hardware ehlukile - cabanga ukuthi isofthiwe idlala kuphela, futhi ulindele ukuthi i-stereo yemoto ingayihoyi.

Ihele AIFF liphele nini nge-bitrate?

Iphutha 192 kbps ku AIFF olahlekelwayo; dlula-nge- AIFF 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 Opus kuya ku AIFF kuzonciphisa kakhulu izinga lami lomsindo?

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

Ingabe i-Opus kuya ku-AIFF igcina amathegi we-ID3 / metadata?

Yebo — isihloko, umculi, i-album, unyaka, inani le-track, i-album art, BPM, ukuphindeka-kwe-gain kufundeka kusuka ku Opus ibhokisi futhi kubhalwe kuma-fields alinganayo ku AIFF ibhokisi. ID3v2 (MP3), amazwana we-Vorbis (OGG, FLAC), ama-MP4 atoms (AAC, M4A), RIFF INFO (WAV), ama-iXML chunks wonke ama-maps ngokuhlanzekile. AIFF Apple's Audio Interchange File Format kusukela 1988, eyenziwe nge IFF efanayo chunk design njenge AVI RIFF.

Ingabe ngingenza ukuguqulwa kwekhulu le Opus amafayela abe AIFF?

Yebo — susa isibaya se Opus 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-AIFF izogcina isilinganiso esifanayo sesampula njenge-Opus?

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

Ingabe ngizolungisa umsindo ku-Opus kuya ku-AIFF?

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

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

Ipayipi lisebenza ngehardware esilawula ngayo kusukela ekuqaleni kuya kukuphela; akukho inkonzo yeqembu lesithathu ethola ifayela lakho.

Ingabe kuthatha isikhathi esingakanani ukushintsha ihora le-Opus libe AIFF?

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 Opus -> AIFF liphele ngemizuzu engu-6-12 ku-pipeline ejwayelekile.

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-AIFF izwakala ifana ne-Opus (nge-lossless) noma ifana ngokuzizwa (nge-translucent lossy).

Opus

I-Opus iyikhodekhi yomsindo evulekile, engenamali enikeza ukucindezelwa kwekhwalithi ephezulu kukho kokubili inkulumo nomsindo ovamile. Ilungele izinhlelo zokusebenza ezahlukahlukene, kufaka phakathi i-voice over IP (VoIP) nokusakaza.

AIFF

I-AIFF (i-Audio Interchange File Format) ifomethi yefayela lomsindo engacindezelwanga evame ukusetshenziswa ekukhiqizweni komsindo nomculo okuphrofeshinali.
