WAV → AC3

Ezinye, futhi zihlala - lokhu kuyindlela eyodwa lapho ulwazi luthunyelwe khona. WAV ligcina yonke imibiko ngokugcwele; AC3 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-WAV njenge-master yakho, ngoba awukwazi ukubuyela kuyo kusuka ku-AC3.

Ama-akhawunti amahhala afinyelela ku-100 MB ngefayela ngalinye, futhi WAV ahamba ku-10 MB ngomzuzu ngayinye kwi-stereo ngoba akukho okucindezelwe - yonke isampula igcinwa ngokubanzi okugcwele. Amaminithi ayishumi akhona emkhawulweni. I-Premium iphakamisa umkhawulo ngokuqinile, futhi ifomu line-4 GB ye-cage yayo ngaphesheya, ngakho-ke izingqungquthela ezide zifika zihlukaniswe zibe yizingxenye ezilinganiselwe; zulazisa ndawonye futhi zithathwa njengemisebenzi eyodwa. 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.

Iphutha 192 kbps ku AC3 olahlekelwayo; dlula-nge- AC3 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 WAV ilahlekelwa (MP3, AAC) futhi AC3 ayilahlekelwanga (WAV, FLAC), AC3 ayingcono kuna WAV — awukwazi ukubuyisela imininingwane elahlekile yi-WAV codec elahlekile. Uma WAV ayilahlekelwanga futhi AC3 ilahlekelwa, cabanga ukuthi i-AC3 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 WAV ibhokisi futhi kubhalwe kuma-fields alinganayo ku AC3 ibhokisi. ID3v2 (MP3), amazwana we-Vorbis (OGG, FLAC), ama-MP4 atoms (AAC, M4A), RIFF INFO (WAV), ama-iXML chunks wonke ama-maps ngokuhlanzekile. AC-3 yiDolby Digital, ifomu elijikelezayo elijwayelekile le-laserdisc, DVD, ATSC broadcast ne-cinema ekuqaleni kuka-1990.

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

Yebo — ukhetho lokujwayelekile-lokujwayelekile lufaka ITU-R BS.1770 / EBU R128 ukujwayelekile ku AC3 kuphuma, libhekisa ku -14 LUFS (isizinda sokushayela) noma -16 LUFS (isizinda sepodcast) noma inani elijwayelekile. Lisetshenziswa uma liguqula amabhayisikobho ngezinga lokuphatha elihlukile ku AC3 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-AC3 codec ephephile ye-platform oyicacisile. AC-3 yi-surround track ngayinye ye-AV receiver, DVD player ne-TV decodes ngokusemthethweni, ngakho-ke ihlala iyi-baseline yokusabalalisa. AC-3 ayisebenzi kahle ngokuya ngemigomo yamanje futhi ayivunyelwe yiziphequluli, amafoni noma abadlali abaningi be-web ngaphandle kokuxhuma phezulu kwe-stereo.

Yebo — amafayela alayishwe phezulu WAV 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 WAV -> AC3 liphele ngemizuzu engu-6-12 ku-pipeline ejwayelekile.
