AC3 → WAV

Akunalutho, futhi kufanelekile ukuba kucace: akukho okuzokwenzeka. I AC3 idlulele i-detail ngesikhathi sokuqothula kwayo okujwayelekile, futhi ukubopha okushiwo ku WAV ongeke ulahlekelwa yilutho kugcina lokho - akukho okuningi. Ihele lithola izikhathi eziningi ezikhulu futhi lizwakala lifana. Kukhona ukunyakaza okulungile ngaphambi kokuhlela, ngoba WAV ngeke ihlanganise isizukulwane sesithathu sezinto ezibonakalayo uma ukhipha. WAV iyifomethi efanele yokuhlela, ukuphatha nokulondoloza, ngoba ingaphinde ikhodwe noma yikuphi inani lamahora ngaphandle kokuqoqa ama-artefacts. AC-3 ayisebenzi kahle ngokuya ngemigomo yamanje futhi ayivunyelwe yiziphequluli, amafoni noma abadlali abaningi be-web ngaphandle kokuxhuma phezulu kwe-stereo.

Iphutha 192 kbps ku WAV olahlekelwayo; dlula-nge- WAV 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 AC3 ilahlekelwa (MP3, AAC) futhi WAV ayilahlekelwanga (WAV, FLAC), WAV ayingcono kuna AC3 — awukwazi ukubuyisela imininingwane elahlekile yi-AC3 codec elahlekile. Uma AC3 ayilahlekelwanga futhi WAV ilahlekelwa, cabanga ukuthi i-WAV 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 AC3 ibhokisi futhi kubhalwe kuma-fields alinganayo ku WAV ibhokisi. ID3v2 (MP3), amazwana we-Vorbis (OGG, FLAC), ama-MP4 atoms (AAC, M4A), RIFF INFO (WAV), ama-iXML chunks wonke ama-maps ngokuhlanzekile. WAV Microsoft kanye IBM RIFF-based audio container kusukela 1991, futhi kuyinto cishe wonke audio interface kanye DAW ubhala kwi-record.

Yebo — susa isibaya se AC3 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 AC3 ikhiqiza 48 kHz WAV, a 44.1 kHz AC3 ikhiqiza 44.1 kHz WAV). Ukusebenza kahle okuthile — isibonelo, ukusatshalaliswa kwe-96 kHz studio masters kuya ku-44.1 kHz WAV ukushaya i-CD, noma ukusatshalaliswa kwe-22 kHz voicemail kuya ku-44.1 kHz WAV — isilinganiso sesampula esiphansi sifaka ukusatshalaliswa kabusha kwekhwalithi ephezulu ye-SOX-style.

Yebo — ukhetho lokujwayelekile-lokujwayelekile lufaka ITU-R BS.1770 / EBU R128 ukujwayelekile ku WAV kuphuma, libhekisa ku -14 LUFS (isizinda sokushayela) noma -16 LUFS (isizinda sepodcast) noma inani elijwayelekile. Lisetshenziswa uma liguqula amabhayisikobho ngezinga lokuphatha elihlukile ku WAV 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-WAV codec ephephile ye-platform oyicacisile. WAV ikhulu kakhulu — cishe i-10 MB ngemingwane ye-stereo ngekhwalithi ye-CD — futhi ifomu elidala line-4 GB ye-loft futhi akukho indawo ye-tags efanele.

Yebo — amafayela alayishwe phezulu AC3 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 AC3 -> WAV 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-WAV izwakala ifana ne-AC3 (nge-lossless) noma ifana ngokuzizwa (nge-translucent lossy).
