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; ulayishe nganye nganye 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.

Okumiselweyo 192 kbps kulahleko MP3; dlula-kwi-lossless MP3. Nciphisa ukuya kwi-320 kbps ukuba ufuna ubukhulu bokungazinzi okulahlekileyo, 128 kbps kunikezelo lwepodcast olukhawulezayo, okanye 96 kbps kumthombo welizwi kuphela apho ifayili encinci ibalulekile ngakumbi kuneenkcukacha zestudio.

Ukuba WAV ilahlekile (MP3, AAC) kwaye MP3 ayilahleki (WAV, FLAC), i MP3 ayingcono kune WAV — awunakubuyisela ulwazi olusele lulahlekile yi-WAV codec. Ukuba i WAV ayilahleki kwaye MP3 iyalahleka, lindele ukuba i MP3 encoder iphinde icinezele; kwi-192 kbps ilahleko ayifumaneki kuninzi lweendlebe.

Ewe — isihloko, umculi, i-albham, unyaka, inani lengoma, ubugcisa be-albham, i-BPM, ukuphinda-udlala-ukufumana kufundwa kwi WAV isiqulathi seefayili kwaye kubhalwa kumacandelo alinganayo kwi MP3 isiqulathi seefayili. ID3v2 (MP3), i-Vorbis impendulo (OGG, FLAC), i-MP4 ii-atoms (AAC, M4A), RIFF INFO (WAV), i-iXML i-chunks zonke iimaphu ngokucocekileyo. I-MP3 yi-MPEG-1 Umphezulu Wosandi III, egqityiwe ngo-1993, kwaye ihlala i-format yesandi ekwazi ukucoda ngokupheleleyo ekhoyo.

Ewe - susa isiqulathi seefayili se WAV kwifayile kwaye siziqhubekeke ngokuthe tye. I-Premium inemisebenzi ethe tye eninzi kwaye akukho bukhulu befayili nganye obuphezulu, ngoko ke i-500-file batch igqiba kwimizuzu kunokuba i-10s yemizuzu. Ukwakhiwa kwesiqulathi seefayili kugcinwa kwimveliso ye-ZIP.

Ngokungagqibekanga ewe (a 48 kHz WAV ivelisa 48 kHz MP3, a 44.1 kHz WAV ivelisa 44.1 kHz MP3). Ukulungelelanisa okuthile — umzekelo, ukunyusa isampuli ye-96 kHz studio masters ukuya kwi-44.1 kHz MP3 yokukhupha i-CD, okanye ukunyusa isampuli ye-22 kHz yeposi yelizwi ukuya kwi-44.1 kHz MP3 — isampuli-ixabiso lokuhla lisebenzisa umgangatho ophezulu we-SOX-style resamply.

Ewe - ukhetho lokwenza lusebenze ngokuqhelekileyo ubukhulu busebenzisa ukwenziwa ngokuqhelekileyo kwe-ITU-R BS.1770 / EBU R128 kwimveliso ye MP3, ibeka i- -14 LUFS (isiqhelo sokusasaza) okanye i- -16 LUFS (isiqhelo sepodcast) okanye ixabiso elimiselweyo. Isetyenziswa xa kutshintshwa iingoma ngemiphakamo emininzi yolawulo kwi-MP3 yoluhlu lokudlala.

I-MP3 idlala ngokubanzi kwisixhobo ngasinye esiyenziwe kwiminyaka emi-20 edlulileyo. I-AAC idlala kwi-Apple, i-Android, i-Sonos, kunye ne-stereo zemoto zakudala. I-FLAC idlala kwi-Sonos ne-Android ekutshanje, isebenza kakubi kwi-iPods ezidala. I-WAV idlala kuyo yonke into kodwa ifayili ikhulu. Isixhobo-esimiselweyo esithe tyaba sikhetha i-MP3 codec ekhuselekileyo ye-platform ocacisayo.
