Ingoma izorekhodwa kokuthi -3 dBFS, futhi ileveli emaphakathi izoba ngaphansi kakhulu kunalokho futhi ngeke iqoshwe noma ihlanekezelwe ngoba ithwetshulwe irekhoda ngaphandle kokuphakama noma yikuphi eduze no-0dBFS.
I-Headroom yomsindo wedijithali

Uma irekhoda yakho isebenza ku-0dBFS kodwa unomsindo omkhulu ozwakalayo, izoqopha ngoba ayikho enye indawo lapho leyo siginali ingaya khona. Umsindo wedijithali awuthetheleli uma kuziwa ekunamathiseleni ngale ndlela.
I-Headroom yomculo obukhoma
I-Headroom iphinda isebenze ngokukhululeka ekuqopheni umculo obukhoma ngokujwayelekile. Uma umsindo uphezulu kakhulu futhi ufinyelela isiqongo ku-0dBFS, uzosikwa.
Ukuba no-3-6 dB we-headroom kuvame ukuba kuningi kokuqoshwa komculo bukhoma, inqobo nje uma irekhodi lakho likwazi ukuphatha amazinga aphezulu kakhulu ngaphandle kokusika.
