AMR → WAV

Hayi, kwaye ixabiso lokuba mnyama: akukho nto ingayenza. I AMR sele ishiye inkcukacha ngexesha lokushicilela kwayo, kwaye ukujika okuseleyo kwi WAV engalahliyo igcina ngokuchanekileyo oko - akukho ngaphezulu. Ifayile ifumana amaxesha amaninzi amakhulu kwaye ithetha ngokufanayo. Ihlala ihamba kakuhle phambi kohlela, kuba WAV ayizukongeza udidi lwesibini lweeartefacts xa urhweba ngaphandle. I-WAV yifomati efanelekileyo yohlela, ulawulo nokugcina, kuba ingaphinde ikhowudiwe nanini na ngaphandle kokudibanisa iindidi. I-AMR ibulala umculo: i-8 kHz bandwidth yayo isusa konke okungaphezulu kweefrequencies zefowuni, kwaye akukho xabiso lokucofa kwakhona liyibuyisela.

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.

Okumiselweyo yi 192 kbps ye-lossy WAV; igqityiwe-kwi-lossless WAV. 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.

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

Ewe — isihloko, umculi, i-albham, unyaka, inani lengoma, kunye nemifanekiso ye-albham ifundwa kwi AMR isiqulathi seefayili kwaye ibhalwe kwi WAV isiqulathi seefayili apho ifomati ixhasa iithagi. Zonke iziseko eziqhelekileyo (MP3, AAC, FLAC, OGG) ziphatha ii-tags kakuhle; i-WAV egqityiweyo ayisebenzi. I-WAV yiMicrosoft ne-IBM RIFF-based audio container ukusukela ngo-1991, kwaye yiyo into eninzi yonke i-audio interface ne-DAW ibhala kwirecord.

Ewe - susa isiqulathi seefayili se AMR 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.

Ngokungagqibekanga ewe — 48 kHz AMR ihlala i-48 kHz kwi WAV. 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.

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

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-WAV codec elungelelaniswe kakuhle kwi-hardware yakho emiselweyo. 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.

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

I-codec efanayo ye-re-mux: 10 ukuya kwi-30 imizuzwana. Yenza kwakhona ikhowudi kwi-codec eyahlukileyo: ngokuqhelekileyo 10 ukuya kwi-20% yobude bomthombo, ngoko ke i-1-iyure AMR → WAV igqiba kwimizuzu emi-6 ukuya kwi-12. Imisebenzi yeqela ihamba ngokufanayo phakathi kwabasebenzayo ukuphucula isantya.
