i upload three lines which wholly come from lame sourc code:

green line is to calculating the 10th sub-critical band' masking curve, and the masking comes  from all sub-critical bands;

others lines are with same meaning.


red line is for the 9th band

red line and green line come from original source code

blue line comes from modified source code;
