AC3 → AAC

Heoi, ā, e tika ana te whakarite i te taha. He ngaro nga āhuahira e rua, nā reira ko te AAC encoder e mahi ana mai i te oro, kua puta kētia e tētahi whakawhitinga psychoacoustic, ā, ko ōna whakataunga anō e whakakotahi ana i te tautuhi tuatahi. I te 192 kbps, i runga ake rānei i te hua, he mārama tonu te hua mō te nuinga o te whakarongo. Mēnā kei a koe tētahi māngai kore ngaro i tētahi wāhi, ka whakakōrerotia te AAC mai i tērā, ka ārai katoa i te whakawhitinga rua.
