Comment (by Kamedo2):
Isn't the lower spreading function applied too much? The quality of lower
frequency is bad when the higher frequency bin is strong. And what makes
320kbps particularly bad? The quality degrades when we have enough
('overkill') bits. I think something fatal is happening, like integer
overflow or something.
