Sample-by-sample I subtracted this from the equivalent 320k aac version.
The resulting set of sample 'difference' values is shown in the lower
graph. Again peak value per 0.1 sec block.


Sorry, just to clarify. The bottom graph shows how much smaller the 'diff'
is *than the signal*. i.e. overall, the difference between aac and flac is,
say, about 40dB below the flac or aac levels.
