DC offset
Da li bi neko mogao detaljnije da pojasni ovu pojavu?
Sta je tacno DC offset, sta ga izaziva (napajanje, zvucna karta, ploca...?), zbog cega trake koje imaju prejak DC pucketaju kada se splituju itd.? Utice li kvalitet struje u mrezi na pojavu DC offseta? Otkud taj jednosmerni napon (DC) na pojedinim trakama i kako to da ih on izbaci iz nule? Da li je pametnije DC offset skidati u masteringu sa stereo trake, ili u Cubaseu sa svake audio trake pojedinacno? |
Svi junaci nikom ponikose i u crne knjige pogledase... :shock: :roll:

DC Filter M/S
Removes any existing DC component from a signal. Both mono and stereo versions of the filter are provided. Controls Gain The DC Filter operates with 6 dB headroom in order to avoid distortion. Typically, these extra dB can be recovered following DC removal via the amplifier stage which follows. However, if the peak-indicator LED begins lighting, the Gain control should be backed off slightly. Signal Peak The signal LED (green) indicates all signals above the level of -96dB. The Peak LED indicates the presence of distortion in the amplifier stage following the DC filter. Ovo sam nasao u pulsarovom manualu, ne odgovara na pitanje ali navodi na zakljucke (bar deo njih) |
Ja sam nasao negde neku nazovi definiciju da je DC offset pojava kada neki elemenat racunara (napajanje, zvucna karta, pci...) doda snimljenom audio signalu jednosmerni napon. To dovodi do toga da traku bude rascentrirana u odnosu na 0... takve trake pucketaju kada se splituju, prave razne problemcice (narocito kada je traka pod efektima), izazivaju losiju stereo sliku...
E sad, ako je neko slagao mene, slagao sam i ja... Ne mogu da se setim gde sam to chitao... hm... neki forum... knjiga Cubase SX... tako nesto... |
