Ngati munayamba mwamvetsera nyimbo za digito - makamaka mtundu uliwonse wotayika wa mauthenga - ndiye kuti mwakhala mukudziwika kuti mukuwerengera masamu. Kuseri kwazithunzi zojambulajambula zamagetsi ndizofala kwambiri ndipo nthawi zambiri zimakhala zofunikira kwambiri pulogalamu yamakono yamakono kapena hardware (mwachitsanzo , otembenuza digito ndi analog ). Koma kungogwiritsidwa ntchito sikumangokhala kumvetsera. Mawuwo ndi ntchito zake amagwiranso ntchito kuzinthu zina, monga fizikiya kapena kujambula kwa digito.
Tanthauzo
Kuyimitsa ndi njira yosinthira miyeso yowonjezera yowonjezereka m'zinthu zing'onozing'ono zomwe zimatulutsidwa zomwe zimayenderana kwambiri ndi deta yoyamba.

Chitsanzo
Mu studio yojambula, ma microphone amajambula mafunde a nyimbo a analog, omwe amawasandutsa mawonekedwe a digito. Chizindikirocho chingakhale sampuli pa 44,100 Hz ndipo chiwerengedwa ndi 8-, 16-, kapena 24-bit kuya (ndi zina zotero). Kuzama kwapamwamba kumapereka deta yambiri, yomwe imathandiza kuti kutembenuka ndi kubalana kwabwino kwa mawonekedwe oyambirira.
Kukambirana
Mwachidziwitso, kugwiritsiridwa ntchito ndi njira yovuta yozungulira yomwe imaphatikizapo kuchuluka kwa kusazindikira. Makompyuta amagwira ntchito pazinthu ndi zeros, chifukwa chake kutembenuka kwa analog-to-digital kumaonedwa kuti ndiyolumikizana kwambiri osati kopindulitsa kwenikweni. Pankhani ya nyimbo, chizindikiro choyenerera chiyenera kukhalabe chokhazikika pamodzi ndi kukula kwake, koma nthawi yake iyeneranso kukhala yolondola. Njirayi iyenera kuonetsetsa kuti nyimbo imasungidwa, ndi zolemba zogawanika zomwe zimagawidwa ndikuyikidwa pamagetsi omwewo (kapena magawo ake). Apo ayi, audio imatha kumveka kapena yachilendo kumvetsera makutu.
Lingaliro ili la kufotokoza lingathe kuwonetsedwa mwachiwonetsero ndi pulogalamu yokonza zithunzi, monga Photoshop. Pamene chithunzi chachikulu chacheperapo kukula, pali kutaya kwa pixel zambiri chifukwa cha dongosolo la masamu kugwira ntchitoyo. Kulogalamuyi imapanga mawerengero ndi kuzungulira kuti ikhale ndi ma pixel osafunika pamene kusunga umphumphu, chiŵerengero, ndi chikhalidwe cha fano - zolimbitsa zofunikira ndizofunikira kwa zithunzi monga nyimbo ndi nyimbo. Pamene akulowetsa mkati ndi kufanizitsa kukonzanso kwake kwa chithunzichi kumayambiriro, m'mphepete mwa zinthu ndi zinthu zimaoneka ngati zowonongeka kapena zowonongeka. Zowonetseratu zomwe zimawonongeka ndi zofanana ndi ma fayilo ojambula. Deta yambiri ndi / kapena kuchepetsedwa pang'ono kumabweretsa khalidwe lapamwamba kwambiri.
