Before going further, just make sure that:
1) You are compiling for fixed-point (FIXED_POINT) and not floating point
2) You have reduced the complexity setting with OPUS_SET_COMPLEXITY()
(see doc for details)
Also, I'm not sure what you mean by "LFE channels" here. Are you doing
surround or stereo?
