Dear All,

        I am DSP engineer working on MP3 decoder implementation. 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.

Regards
Tam
