WAV → MP3

Ezinye, kwaye zihlala zikhona - le yindawo enye apho ulwazi luza kuthuthwa khona. WAV igcina yonke imilinganiselo ngokuchanekileyo; MP3 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 MP3.

Ewe, kwaye yimpumelelo epheleleyo ngaphezulu kwe WAV, eyona ingekho naphi na ethembekileyo ukugcina nayiphi na. MP3 ithatha isihloko, umculi, i-albham, unyaka, inani lengoma kunye nobugcisa bokuqhoboshela okufakwe kwisiqulathi seefayili, ngoko ithala leencwadi lengoma liyifaka ngokuchanekileyo ngaphandle kokuhamba ngesandla. Akukho nto ibetha iMP3 ekusebenzeni kwayo - iistereo zemoto, izixhobo zegym, iiDAPs kunye nezixhobo zekhompyutha ezineminyaka engama-20 ubudala zonke zifunda ngaphandle kwemibuzo.

Ijika ezantsi kwi-stereo, kuba MP3 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. MP3 igqityiwe nge AAC ne Opus kwinqanaba ngalinye le-bitrate, ayikwazi ukugcina ngaphezulu kweendawo ezimbini eziluncedo, kwaye ihlala idibanisa ulibaziso oluncinci lwe-encoder.

Ii-akhawunti ezikhululekileyo zigqityiwe kwi-100 MB kwifayile nganye, kwaye WAV iqhuba ukuya kwi-10 MB ngomzuzu kwi stereo kuba akukho nto ingqutywe ngayo - isampuli nganye igcinwa kubukhulu obupheleleyo. Iimizuzu elishumi sele ikwinqanaba lokungena. 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; zulazisa ngazo kunye kwaye zithathwe njengemisebenzi enye. 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.

Okungagqibekanga ku 192 kbps kulahleko MP3; dlula- kwi-lossless MP3. 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.

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

Ewe - isihloko, umculi, i-albham, unyaka, inani lengoma, kunye nemifanekiso ye-albham ifundwa kwi WAV isiqulathi seefayili kwaye ibhalwe kwi MP3 isiqulathi seefayili apho ifomati ixhasa amaphetshana. Zonke izicelo eziqhelekileyo (MP3, AAC, FLAC, OGG) ziphatha amaphetshana kakuhle; i-raw WAV ayisebenzi. I-MP3 yi-MPEG-1 Umphezulu Wosandi III, egqityiwe ngo-1993, kwaye ihlala i-format yesandi ekwazi ukucoda ngokupheleleyo ekhoyo.

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.

Ngokungagqibekanga ewe — 48 kHz WAV ihlala 48 kHz kwi MP3. Ukuba ufuna ukunyusa uvavanyo ukuze ulungelelanise (96 kHz → 44.1 kHz ukukhuphela iCD), ukhetho lwesampulu-yesantya lusebenzisa uvavanyo oluphezulu lomgangatho kwindlela efanayo yokugqitha kokukhowuda.

Ewe - ukhetho lokwenza isantya sisebenze ngokuqhelekileyo lusebenzisa ITU-R BS.1770 / EBU R128 ukwenziwa sebenze ngokuqhelekileyo kwi MP3, lujolise kwi -14 LUFS (umgangatho wokudlulisa) okanye -16 LUFS (umgangatho wepodcast). Isetyenziswa xa kuqhutywa iingoma ezimasterwe kumanqanaba ahlukeneyo.

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 MP3 esilungele i-hardware yakho emiselweyo.
