(Active Coding-3) Dolby's third digital audio coding technology based on a perceptual coding method. Introduced in 1991 initially for surround sound in theaters, AC-3 is more advanced than AC-2 and provides six channels of audio in less space than a two-channel stereo CD. AC-3 and "Dolby Digital" are synonymous. See Dolby Digital, AC-1 and AC-2.

Optimum condition for producing activated carbon (AC3) from Moringa oleifera seed pod was activated at 800degC using ZnCl2 as activating agent resulting BET surface area 853.68 m2g-1 and pore diameter 2.13 nm.
The results obtained for the surface areas of the A[C.sub.s] are consistent with the previous statement, since they follow the order AC1 = 309 [m.sup.2][g.sup.-1] > AC2 = 479 [m.sup.2][g.sup.-1] > AC3 = 889 [m.sup.2][g.sup.-1] > AC4 = 557 [m.sup.2][g.sup.-1] > AC5 = 902 [m.sup.2][g.sup.-1] > AC6 = 1715 [m.sup.2][g.sup.-1].
Segundo Quaggio (2000) o evento era esperado pela serie de retencao de cations, que determina que o Ca e mais fortemente retido na matriz coloidal do solo do que o Mg; apesar disto, os [[IQ.sub.i]sub.i] para Ca variaram de 0,56 a 1,00 enquanto para o Mg apenas AC3 e AC7 apresentaram [IQ.sub.i] maiores que 0,90, sendo os menores [[IQ.sub.i]sub.i] de 0,033 para AC2 e AC6 devido ao aumento dos teores de Mg nas duas areas, passando de 0,59 na mata nativa para 1,60 cmol [dm.sup.-3].
