[FFmpeg-devel] [PATCH] aacenc: Correct spreading calculation in the 3GPP psymodel.

[Nathan Caldwell]

Spreading is currently being calculated incorrectly. We were
multiplying the previous band
threshold by the lower spreading factor, and the next band by the
higher spreading
factor. Also, the first spreading loop was using the spreading factor for the
previous band, instead of the spreading factor for the current band.

I've found this fix to be most noticeable in the Tom's Diner sample.
