AC3 ukuba AMR Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-AC3 yesandi ibe yi-AMR ngaphandle kokulahlekelwa umgangatho?

Layisha phezulu ifayili AC3 kwaye umguquli ukhetha i AMR codec ne-bitrate ukuhambelana nomcebo. Ukungabikho kolahleko AMR (WAV / FLAC / ALAC) ugcina yonke isampuli nge-bit-identical; ukungabikho kolahleko AMR (MP3 / AAC / OGG / Opus) okumiselweyo ku 192 kbps ebonisa ngokucacileyo kwiinwele ezininzi. AC-3 yisandi esilahlekileyo esingenasiqhagamshelanisi esininzi, sihlala siyi-5.1 kwi-384 okanye 448 kbps, nemetadata yonxibelelwano oluqhelekileyo noluphantsi koxinzelelo. I-AMR yi-codec yokuthetha ehamba phakathi kwe-4.75 ne-12.2 kbps, eyenza imodeli yomsebenzi wokuthetha womntu kunokuba isebenze kwi-audio epheleleyo.

Ingaba ukutshintsha AC3 ukuya ku AMR kujikelezo lwesibini lokucinezela okulahlekileyo?

Ewe, kwaye kufanelekile ukucwangcisa. Zonke iifomati zilahlekile, ngoko ke i AMR encoder isebenza kwisandi esisele sidlula kwindlela enye ye psychoacoustic, kwaye izigqibo zayo zidibanisa iseti yokuqala. Kwi 192 kbps okanye ngaphezulu isiphumo sihlala sicacile kubaninzi bokuziva. Ukuba une master engalahleki naphi na, ukukopela i AMR ukusuka apho endaweni yoko ikhusela i pass kabini ngokupheleleyo.

Ithini into ebangela ukuba i-multichannel yesandi iguqulwe kwi AC3 ukuya kwi AMR?

Ijika ezantsi kwi-stereo, kuba AMR ayinayo indlela esebenzayo ye-multichannel. Ukudibanisa ezantsi kusetyenziswa izilinganisi eziqhelekileyo ukuze unxibelelwano lwe-center-channel luhlale lucacileyo kwaye izijikelezi-ndawo zidityanisiwe kwinqanaba eliphantsi. Nantoni na exhomekeke kukubeka isiqhagamshelanisi esikhethekileyo iphela xa oku kwenzeka. I-AMR ibulala umculo: i-8 kHz bandwidth yayo isusa konke okungaphezulu kweefrequencies zefowuni, kwaye akukho xabiso lokucofa kwakhona liyibuyisela.

Kutheni umculo uthetha ntoni xa uguqulwa?

Kuba enye icala liyi codec yokuthetha kune codec yengoma. Imodelisa umjelo wokuthetha womntu kwaye ishiya konke ngaphandle kwe bandwidth yefowuni, elungileyo kwimemo yokuthetha kwaye ilahlekile nantoni na enezixhobo kuyo. Ukutshintsha kude nayo akuyi kubuyisela uxinzelelo olulahlekileyo - akufuneki kubekho ukuvulwa kwindawo yokuqala. AC-3 ayisebenzi kakuhle ngemigangatho yangoku kwaye ayivunyelwanga ziibrowser, iifowuni okanye abadlali abaninzi bewebhu ngaphandle kokudibanisa phantsi kwistereo.

I-AMR ifayili ephumayo izakusebenzisa i-bitrate enjani?

Okumiselweyo yi 192 kbps ye-lossy AMR; igqityiwe-kwi-lossless AMR. Nciphisa kwi 320 kbps ye-audiophile okanye 96 kbps yelizwi/podcast. Ukhetho lutshintshiselana ngobungakanani befayili ngokuchasene nobuxoki obunokulungiswa; ngaphantsi kwe-96 kbps i-lossy artifacts ibonakala kwingoma.

Ingaba ukutshintsha ukusuka ku AC3 ukuya ku AMR kuya kunyusa ubunjani besandi sam?

Ukuba AC3 ilahlekile kwaye AMR ayilahleki (umzekelo MP3 → WAV), i AMR ayingcono kune AC3 — awunakubuyisela ulwazi olusele lulahlekile. Ukuba AC3 ayilahleki kwaye AMR ilahlekile, i AMR codec iphinda icinezele; kwi-192 kbps isiphumo sicacile kumxholo omkhulu.

Ingaba i-AC3 ukuya kwi-AMR igcina i-ID3 / i-metadata tags?

Ewe — isihloko, umculi, i-albham, unyaka, inani lengoma, kunye nemifanekiso ye-albham ifundwa kwi AC3 isiqulathi seefayili kwaye ibhalwe kwi AMR isiqulathi seefayili apho ifomati ixhasa iithagi. Zonke iziseko eziqhelekileyo (MP3, AAC, FLAC, OGG) ziphatha ii-tags kakuhle; i-WAV egqityiweyo ayisebenzi. I-AMR yi-Adaptive Multi-Rate, i-codec yokuthetha ye-3GPP emiselwe kwi-GSM yezingxoxo zelizwi kunye nezixhobo zokurekhoda ilizwi elihambayo.

Ndingaguqula izigidi zeefayili AC3 zibe AMR?

Ewe - susa isiqulathi seefayili se AC3 ngaphakathi kwaye siza kuziqhubekekisa ngokuthe tye. I-Premium inemisebenzi ethe tye eninzi kwaye akukho bukhulu befayili nganye obuphezulu, ngoko ke i-500-file batch igqiba kwimizuzu kunokuba iphele kwimizuzu emininzi.

Ingaba i-AMR iya kugcina inqanaba lesampuli elifanayo njenge-AC3?

Ngokungagqibekanga ewe — 48 kHz AC3 ihlala i-48 kHz kwi AMR. Ukuba ufuna ukunyusa isampuli ukuze ihambelane (96 kHz → 44.1 kHz yokushicilela i-CD), ukhetho lwesampuli-yexabiso lisebenzisa ukuphinda uthathe isampuli esezingeni eliphezulu kwindlela efanayo yokugqitha kwekhowudi.

Ndingazilungisa njani i-loudness xa ndiguqula i-AC3 ibe yi-AMR?

Ewe - ukhetho lokwenza lusebenze ngokuqhelekileyo ubukhulu busebenzisa ukwenziwa ngokuqhelekileyo kwe-ITU-R BS.1770 / EBU R128 kwi AMR, ukubeka injongo kwi-LUFS -14 (isiqhelo sokusasaza) okanye kwi-LUFS -16 (isiqhelo sepodcast). Isetyenziswa xa kudityaniswa iingoma ezilawulwa kumanqanaba ahlukeneyo.

Ingaba i-AMR yam iya kudlala kwi-stereo yemoto, i-iPod, kunye ne-Sonos?

I-MP3 idlala naphi na. I-AAC idlala kwi-Apple, i-Android, ne-Sonos. I-FLAC idlala kwi-Sonos ne-Android kodwa ayiyiku-iPods ezidala. I-WAV idlala naphi na kodwa ikhulu. Isixhobo esiphambili esimiselweyo esithe nkqo sikhetha i-AMR codec elungelelaniswe kakuhle kwi-hardware yakho emiselweyo. I-AMR isenza ukuba urekhodo lwesandi lube luncinci kakhulu - iyure enye yokuthetha ilungele ii-megabytes ezimbalwa - kwaye yiyo loo nto ifowuni ezininzi zihlala zirekhoda kuyo uqhagamshelwano.

Ingaba ifayili yam AC3 ifihlakeleyo ngexesha lokuguqulwa ukuya kwi AMR?

Ewe — iifayile ezilayishwe phezulu AC3 ziqhubekekiswa kubasebenzi abakhethekileyo kwaye zicinywe kwimizuzu. Asiyi kudlala kwakhona, sigcine ixesha elide, okanye sisebenzise imixholo yesandi. Ifestile yokugcina epheleleyo ikwi /privacy/.

AC3

I-AC3 (i-Audio Codec 3) yifomati yocinezelo lwe-audio edla ngokusetyenziswa kwi-DVD kunye ne-Blu-ray disc audio tracks.

AMR

I-AMR (I-Adaptive Multi-Rate) yifomathi yocinezelo lwe-audio elungiselelwe ikhowudi yentetho. Iqhele ukusetyenziswa kwiifowuni eziphathwayo ukwenzela ukurekhoda kwelizwi kunye nokudlala kwakhona.
