Ib txwm dither rau me ntsis- depth koj xav tau. Ib qho siab dua, thiab koj kawg txiav tawm cov khoom. Ib qho qis dua, thiab koj pov tseg qhov kev daws teeb meem ntxiv. Thiab yog tias koj tab tom ua rau koj cov suab paj nruag muaj nyob rau hauv hi-res hom, tej zaum koj yuav xav tau luam ib qho ntxiv rau 24-ntsis, tsis yog 16-ntsis, los khaws qhov kev daws teeb meem ntxiv.
Koj tso dither qhov twg?
Txoj kev yooj yim tshaj plaws los saib yog tias koj yuav tsum ib txwm dither thaum nqes mus rau qhov tob me ntsis. Yog li, yog tias koj mus los ntawm 24-ntsis mus rau 16-ntsis, koj yuav tsum tau dither. Yog tias koj mus los ntawm 32-ntsis qhov chaw ruaj khov (tsis yog ntab taw tes) mus rau 24- lossis 16-ntsis, koj yuav tsum tau dither.
Thaum twg koj yuav tsum thov dither?
Teb sai. Dithering yog tus txheej txheem ntawm kev ntxiv suab nrov rau lub teeb liab, nyob rau hauv kev rau siab rau daim npog qhov ncauj thiab randomize ntau dua-order harmonics, thiab nyob rau hauv lem, ua quantization distortion tsawg perceivable. Dithering yuav tsum tsuas yog siv thaum lub sijhawm ua tus tswv, thiab tsuas yog thaum qhov tob me ntsis ntawm lub teeb liab raug txo.
Puas dither nce suab nrov hauv pem teb?
Dithering yog txheej txheem ntawm kev ntxiv qhov tseem ceeb ntawm lub suab nrov dawb rau hauv lub teeb liab, npog ntsej muag thiab randomize cov teebmeem ntawm quantization distortion. Qhov zoo tshaj plaws, cov txheej txheem no yuav ua rau qis suab nrov hauv pem teb, thiab tsim kom muaj kev paub ntau dua dynamic ntau (qhov no tshwm sim ntau dua li qhov tob me ntsis).
Puas yog qhov zoo lossis qhov phem?
Qhov kev vibration ntawm lub dav hlau lub cav tau pab ua kom qhov tseeb ntawm cov nplaum txav hauv cov tshuab. Lub suab nrov uas dithering ntxiv rau koj cov lem ua haujlwm ib yam nkaus. Nws pab ua kom qhov tseeb ntawm koj cov ntaub ntawv suab digital.
