Kuzama Kwakuya Tanthauzo ndi Kufotokozera
Mu audio yadijito, payenera kukhala phindu linalake lofotokozera kuthetsa kwa deta (audio) zomwe ziyenera kulandiridwa ndi kusungidwa mu fayilo. Chikhumbo ichi chimatchedwa bit akuya.
Mofananamo, kwa mafayilo a zithunzi ndi mavidiyo, mndandanda wa zoyimirawu umagwiritsidwanso ntchito kuti mudziwe kuthetsa chithunzi. Kukwera pang'ono (monga 16 bit ndi 24 bit) bwino chithunzi chidzakhala.
Chidziwitso ichi ndi chimodzimodzi kwa voliyumu ndikumveka kwapamwamba kwambiri kumvetsera kumapereka zojambula zomveka bwino.
Kuzama pang'ono kungasokonezeke ndi pang'ono , koma ndi osiyana kwambiri. Mtengo Wache (kuyesedwa mu Kbps ) ndi kusinthidwa kwa deta pamphindi pamene phokoso liwonetsedwa mmbuyo, ndipo sikutanthauza sampuli iliyonse yodula yomwe imapanga mawonekedwe a audio. Onani Zozama Pang'onopang'ono ndi Mpata Wambiri kuti mudziwe zambiri.
Zindikirani: Nthaŵi zina zimatchulidwa monga zojambulajambula, zosinthidwa, kapena kutalika kwa mawu.
Zambiri Zambiri pa Kuzama Kwambiri
Chigawo chakulingalira kwazing'ono kwambiri chiri muzinthu zowerengeka (mabedi) ndi kuwonjezeka kulikonse kwa 1-bit, kulondola kwapitirira. Mndandanda uwu ndi chiwerengero chofunikira chomwe chimatsimikizira kuti kujambula bwino (nyimbo zina mwachitsanzo) kumveka.
Ngati zozamazo ndizochepa kwambiri, kujambula sikungakhale kolondola kwambiri ndipo phokoso lamtendere lingawonongeke. Kwa nyimbo zomwe mumapanga laibulale yamakina a digito, ma MP3 omwe adasinthidwa kuchokera ku PCM ya ma audio (kawirikawiri WAV ) mozama kwambiri amakhala ndi mafupipafupi ochulukirapo poyerekeza ndi omwe atsekedwa kuchokera ma fayilo apachiyambi a PCM kuya kwakuya.
Mwachidziwitso, iwo adzakhala olondola kwambiri pa kusewera. Monga tafotokozera kale, chidutswa chakuya ndi chofunikira makamaka pochita ndi mafilimu otetezeka mu nyimbo - kugwiritsira ntchito mozama kwambiri kungapangitse maulendo osowa.
Kuzama kwazomwe kumakhala kofunikira pokhapokha ngati pali chizindikiro cha PCM, ndichifukwa chake machitidwe osowa mafilimu osokonezeka alibe zozama.
Njira Zina Zozama Kwambiri Zimakhudza Makhalidwe Abwino
Kuonetsetsa kuti mafayilo anu ojambula adiresi sakuvutika ndi kuwongolera n'kofunika, koma kukhala ndi chidziwitso choyenera ndichinthu chofunikira kwambiri kuganizira pofuna kuchepetsa kuchuluka kwa phokoso lakumbuyo.
Zojambula zonse zili ndi kusokonezeka kwa mayina (kutchedwa phokoso la phokoso) limene lingasungidwe osachepera ngati likugwiritsa ntchito mokwanira mokwanira. Izi ndizo chifukwa kusiyana kwakukulu (kusiyana pakati pa mawu okweza ndi mawu achisoni) kudzakhala kokwera kwambiri kusiyana ndi phokoso la phokoso, kulola kusiyana kulira phokoso pang'onopang'ono.
Kuzama pang'ono kumatanthauzanso momwe kujambula kulira kwakukulu. Kwa kuwonjezeka kwapang'ono kulikonse, pali pafupifupi 6 dB ya zowonjezera kukula. Mafilimu otchuka kwambiri omwe amagwiritsidwa ntchito lerolino ndi ma CD, omwe amagwiritsa ntchito pang'ono, 16, yomwe imagwirizana ndi 96 dB yazitali. Ngati DVD kapena Blu-ray ikugwiritsidwa ntchito, khalidwe lakumveka ndilopamwamba chifukwa momwe akugwiritsiridwa ntchito mozama ndi 24, zomwe zimapereka 144 dB za kutalika kwake.
