Zikondwerero Zolemba Ma MP3
Mau oyamba
Pulogalamu ya MP3 ndi yotchuka kwambiri yomvetsera mafilimu yomwe ikugwiritsidwa ntchito masiku ano ndipo yatha zaka zoposa khumi. Kupambana kwake kungakhale makamaka chifukwa chogwirizana ndi chilengedwe chonse. Ngakhale ndi zotsatirazi, pali malamulo omwe muyenera kudziwa musanayambe ma MP3 mafayilo. Zinthu zotsatirazi zidzakupatsani lingaliro la momwe mungasinthire makonzedwe anu a encoding kuti mupeze zotsatira zabwino.
Mtengo wamagetsi
Kuti muzisankha zoyenerera zamakono zoyenera muyenera kuganizira mozama mtundu wa chithunzi. Mwachitsanzo, ngati mutseketsa kujambula kwa mawu otsika kuchokera pa tepi ya analog ndikugwiritsa ntchito makonzedwe apamwamba kwambiri okhomeretsa, ndiye izi zidzasokoneza malo ambiri osungirako. Ngati mutasintha fayilo ya MP3 yomwe imakhala ndi 96 kbps mu imodzi yokhala ndi 192kbps pang'onopang'ono ndiye palibe kusintha kwa khalidwe kudzachitika. Chifukwa cha ichi ndi chakuti choyambirira chinali 32kbps zokha ndipo chotero chilichonse choposa ichi chidzangowonjezera kukula kwa fayilo ndipo sichidzasintha ndondomeko yabwino.
Nazi zina zomwe zikuyimira bitrate zomwe mungafune kuyesera:
- 32 kbps - Ma tepi a mawu / analoji.
- 128 mpaka 192 kbps - Kutsika nyimbo kuchokera ku CD.
- 192 mpaka 320 kbps - Kulembetsa zovuta zowonjezera mauthenga (zomwe zili ndi maulendo ambiri, monga nyimbo zoyamba).
Kutaya kwa Lossy
Ma MP3 ndi mtundu wotayika ndipo ukutembenuzidwa ku mtundu wina wotayika (kuphatikizapo wina MP3) sali woyenera. Ngakhale mutayesa kutembenukira ku bitrate apamwamba, mudzasungabe khalidwe. Kawirikawiri ndibwino kuchoka pachiyambi monga momwe zilili, kupatula ngati mukufuna kuchepetsa malo osungirako ndipo musaganize kuchepetsa kusamvana kwawomveka.
CBR ndi VBR
Nthawi zonse (bitrate) ( CBR ) ndi variable bitrate ( VBR ) ndizozigawo ziwiri zomwe mungasankhe pakukweza ma MP3 omwe onse ali ndi mphamvu ndi zofooka zawo. Musanapange chisankho chogwiritsa ntchito CBR kapena VBR muyenera kuganizira mozama momwe mudzamvera nyimbo. CBR ndiyimira zosasinthika zomwe zimagwirizana ndi makina onse a MP3 komanso zipangizo zamakina koma sizimapanga fayilo ya MP3 yopangidwa bwino kwambiri. Mwinanso, VBR imapanga MP3 file yomwe imapangidwira kukula kwa fayilo ndi khalidwe. VBR imakhalabe njira yothetsera mavuto koma nthawi zonse sizimagwirizana ndi hardware yakale ndi ena olemba ma CD.
