Yes I know, thanks for reminding :) This patch does not touch endian
conversion for the input data, so everything should be OK. Anyway, it's
better to do some real tests on big-endian systems just to be sure.
The endian conversion and channels deinterleaving part for the input data
is actually another performance bottleneck in SBC and can be also optimized.
