Hi Tam, Frequency inversion is done in IMDCT block. After IMDCT all samples are in time domain. Subband synthesis re-arranges the time domain samples as per frequency characteristics. Subband synthesis is follows the IMDCT block.
I hope it helps you.

I got doubts while analyzing subband synthesis and IMDCT. In between these two modules, frequency inversion is done for IMDCT output samples. Why is it done here??. What will happen if it is not done? I have searched many forums but couldn't able to get. Eagerly expecting your response.
