[Mp4-tech] [Audio] Initial value of kx'

[Alex Converse]

Hi all,
ISO/IEC 14496-3:2005 section 4.6.18.5, page 226 states: "At start-up
lTemp, kx' and bsco' are set to zero." But the reference decoder
(ISO/IEC 14496-5:2001/Amd.10:2007) initializes it in ct_sbrdec.c:472
with: "sbrDec.prevLowSubband[i] = (int) (upsampleFac * 32);" which sets
it to 64. Can I get a clarification here? Is it supposed to be 0 or 64
or am I misunderstanding something?
Thanks,
Alex Converse
