AIFF ukuba AMR Imibuzo Ebuzwa Rhoqo Ngokuguqula

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

Layisha phezulu ifayili AIFF 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. I-AIFF igcina i-PCM engacinezelwanga encinci-ephakathi — i-Apple-side elinganayo ne-WAV, nge-bit-per-bit fidelity efanayo. 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 ndilahlekelwe yintoni ngokuguqula i AIFF ibe yi AMR?

Ezinye, kwaye zihlala zikhona - le yindawo enye apho ulwazi luza kuthuthwa khona. AIFF 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 AIFF njengenkosi yakho, kuba awunakubuyela kuyo ukusuka kwi AMR.

Ingaba izihloko zam zengoma kunye nemifanekiso ye-albham iya kuqhubeka iphila kwi AIFF ukuya kwi AMR uguqulo?

Ayiqhelekanga. AIFF ihambisa i-metadata efanelekileyo, kodwa AMR ayinandawo eqhelekileyo yomsebenzi womculi, i-albham, inani lengoma okanye ubugcisa besiqhoboshelo, ngoko ke iimpawu zilahliwe endaweni yokulahleka. Gcina i AIFF njengekopi ephawulweyo, okanye uphinde uphawule emva koko ngesixhobo njenge Mp3tag okanye iMusicBrainz Picard. I-AMR ibulala umculo: i-8 kHz bandwidth yayo isusa konke okungaphezulu kweefrequencies zefowuni, kwaye akukho xabiso lokucofa kwakhona liyibuyisela.

Ithini into ebangela ukuba i-multichannel yesandi iguqulwe kwi AIFF 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.

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-AIFF ikhulu njenge-WAV enesixhaso esibi ngaphandle kwehlabathi le-Apple, ngoko ke kukhetho olubi lokusasaza.

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 AIFF ukuya ku AMR kuya kunyusa ubunjani besandi sam?

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

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

Ewe — isihloko, umculi, i-albham, unyaka, inani lengoma, kunye nemifanekiso ye-albham ifundwa kwi AIFF 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 AIFF zibe AMR?

Ewe - susa isiqulathi seefayili se AIFF 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-AIFF?

Ngokungagqibekanga ewe — 48 kHz AIFF 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-AIFF 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.

AIFF

I-AIFF (i-Audio Interchange File Format) yifomathi yefayile yeaudio engaxinzelelwanga edla ngokusetyenziswa kwimveliso yomsindo kunye nomculo.

AMR

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