[mad-dev] About subband synthesis

Hello all,

I am trying to improve the performance of the MP3 decoder. One idea is to improve the subband synthesis. In the MAD, the subroutine, synth_full(), process the subband synthesis. In this subroutine, it can be found that the data (dct32 output) is accessed sequentially. However, the coefficients (synthesis window) is not accessed sequential. I am trying to modify the subroutine in order to access the coefficients sequentially. My question is that where can i find the document about the flow of the subroutine or suggestion.

thanks a lot!! Best Regards
