To ti je kad u midiju (napr) sviras uz takt, naravno netacno a onda uradis kvantizaciju pa ti program sam pomeri note do prvog tacnog tempa koji si odabrao kao referentnu podelu -napr 1/16...

Kvantizacija ti je raspoređivanje amplitude (koja je u realnosti u realnoj domeni i ima beskonacno mnogo vrijednosti) na konačni broj diskretnih razina. Npr signal kojem je amplituda od 0 do 2V uz 4-bitnu kvantizaciju ti ima 2^4 razina, odnosno 16 razina. To znači da imamo 16 razina po 0.125 volt. Binarno (u računalima) ti to znači da će npr vrijednost 0001 označavati amplitudu od 0.125 volti.

edit: sad tek sku?ih da si već sku?io -.-

kvantizacija je opšti pojam koji se odnosi na uokviravanje vrednosti generalno. U audio svetu eto postoji ta kvantizacija nota (kad se note koje su odsvirane blago van time-a lepe po nekom kriterijumu za tačne barove ) i kvantizacija ulaznog audio signala u konverter,kad sam konvertere mora da odluči u koju vrednost da zapiše nivo tog ulaznog signala, jer konverter ima fixni broj vrednosti, a analogni zvuk nema, već je funkcija sam po sebi.
