Some volume reduction is ok, especially if it means we avoid another overflow.
Anyway, it looks like the commit is in.
Thanks again.

Hi Brad!
I would say:
"I am not sure if last version(64bits) of decode with 4 subbands is
correct about overflows."

Hi Brad!
The volume drop is not significant.
Comparing the versions, I didn't see any change in quality with my
headphone, so I think that we can change to 32bits.
By the way, I am not sure if last version of decode with 4 subbands is
correct about overflows.

How significant is the volume drop in 4 subbands? Should we just leave
the decoder at 64 bit mults so we don't needlessly suffer quality
issues on faster platforms?
