WAV ukuba AMR Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani i-WAV yesandi kwi-AMR ngaphandle kokulahlekelwa umgangatho?

Layisha phezulu ifayile WAV kwaye umguquli ukhetha i AMR codec ne-bitrate ukuhambelana nomcebo. Ukungabikho kolahleko AMR (WAV / FLAC / ALAC) ugcina yonke isampuli ye-bit- identical; ukungabikho kolahleko AMR (MP3 / AAC / OGG / Opus) okumiselweyo ku 192 kbps ebonisa ngaphaya kweendlebe ezininzi. I-WAV igcina i-PCM engacinezelwanga emnyama - yonke isampuli igcinwa ngokuchanekileyo, nakweyiphi na ubunzulu be-bit kunye nesantya sesampuli esithathwe. I-AMR yi-codec yokuthetha ehamba phakathi kwe-4.75 ne-12.2 kbps, imodelisa umjelo wokuthetha womntu kunokuba iqulethe i-audio spectrum.

Ingaba ndilahlekelwe yintoni ngokuguqula i WAV ibe yi AMR?

Ezinye, kwaye zihlala zikhona - le yindawo enye apho ulwazi luza kuthuthwa khona. WAV igcina yonke imilinganiselo ngokuchanekileyo; AMR isusa into eyenza imodeli ye psychoacoustic ilindele ukuba awuzukuyiva. Kwi 192 kbps nangaphezulu loo lindeleko kulungile ngokwaneleyo ukuba icacile kwizinto ezininzi nezixhobo ezininzi. Gcina i WAV njengenkosi yakho, kuba awunakubuyela kuyo ukusuka kwi AMR.

Ithini into ebangela ukuba i-multichannel yesandi iguqulwe kwi WAV 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: ububanzi besantya sayo esiyi-8 kHz bususa konke okungaphezulu kwesantya sefowuni, kwaye akukho xabiso lokucofa kwakhona olungayibuyisela.

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. I-WAV inamandla amakhulu - malunga ne-10 MB ngemizuzu ye-stereo kwi CD elungileyo - kwaye i-classic format ine-4 GB ye-ceiling kwaye akukho ndawo ye tags efanelekileyo.

Ingaba urekhodo olude WAV luza kukhupha ngokuphumelelayo?

Ii-akhawunti ezikhululekileyo zigqitha kwi-100 MB kwifayili nganye, kwaye WAV iqhuba ukuya kwi-10 MB ngomzuzu kwi-stereo kuba akukho nto malunga nayo icinezelwe - isampuli nganye igcinwa kubukhulu obupheleleyo. Iimizuzu elishumi sele zikwinqanaba. I-Premium iphakamisa i-cap ngokucacileyo, kwaye ifomati ine-4 GB ye-cage yayo ngaphezulu kwayo, nto leyo eyenza ukuba iintlanganiso ezide zifike zihlukaniswe zibe ziinkalo ezilinganisayo; ulayishe nganye nganye kwaye zithathwe njengemisebenzi enye.

I-bitrate yefayili ephumayo AMR iza kusetyenziswa ntoni?

Okungagqibekanga ku 192 kbps kulahleko AMR; dlula- kwi-lossless AMR. Nciphisa ku 320 kbps ku audiophile okanye 96 kbps kulizwi / ipodcast. Ukhetho lurhweba ubungakanani befayile ngokuchasene nobuxoki obuvakalayo; ngaphantsi kwe 96 kbps ulahleko lwee-artefacts zibonakala kwingoma.

Ingaba ukudlula kwi WAV ukuya kwi AMR kuya kunyusa ubunjani besandi sam?

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

Ingaba umguquli WAV ukuya ku AMR ugcina i-ID3 / i-metadata tags?

Ewe - isihloko, umculi, i-albham, unyaka, inani lengoma, kunye nemifanekiso ye-albham ifundwa kwi WAV isiqulathi seefayili kwaye ibhalwe kwi AMR isiqulathi seefayili apho ifomati ixhasa amaphetshana. Zonke izicelo eziqhelekileyo (MP3, AAC, FLAC, OGG) ziphatha amaphetshana kakuhle; i-raw WAV 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 WAV zibe AMR?

Ewe - shiya isiqulathi seefayili se WAV iifayile ngaphakathi kwaye siza kuziqhubekekisa ngokuthe tye. I-Premium inemisebenzi emininzi ethe tye kwaye akukho mda wobungakanani befayili nganye, ngoko ke i-500-file batch igqiba kwimizuzu kunokuba i-10 yemizuzu.

Ingaba i AMR iyagcina ixabiso lesampuli elifanayo njenge WAV?

Ngokungagqibekanga ewe — 48 kHz WAV ihlala 48 kHz kwi AMR. Ukuba ufuna ukunyusa uvavanyo ukuze ulungelelanise (96 kHz → 44.1 kHz ukukhuphela iCD), ukhetho lwesampulu-yesantya lusebenzisa uvavanyo oluphezulu lomgangatho kwindlela efanayo yokugqitha kokukhowuda.

Ndingazilungisa njani i-loudness xa ndiguqula WAV ukuya ku AMR?

Ewe - ukhetho lokwenza isantya sisebenze ngokuqhelekileyo lusebenzisa ITU-R BS.1770 / EBU R128 ukwenziwa sebenze ngokuqhelekileyo kwi AMR, lujolise kwi -14 LUFS (umgangatho wokudlulisa) okanye -16 LUFS (umgangatho wepodcast). Isetyenziswa xa kuqhutywa iingoma ezimasterwe kumanqanaba ahlukeneyo.

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

I-MP3 idlala naphi na. I-AAC idlala kwi-Apple, i-Android, ne-Sonos. I-FLAC idlala kwi-Sonos ne-Android kodwa ayisebenzi kwi-iPods edala. I-WAV idlala naphi na kodwa ikhulu. Isixhobo esiphambili esimiselweyo esikhupha i-codec AMR esilungele i-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.

WAV

Iifayile ze-WAV zigcina isandi kwifomathi engacinezelwanga, nto leyo enika isandi esisemgangathweni we-CD esifanelekileyo kumsebenzi wesandi wobuchwephesha.
