a MPEG2 question - ZiP HE - Nov 28 2:45:00 2000

Dear all,
I am a newcomer in DSP, and now working on MPEG-2 Audio Encoder. In ISO11172-3
encoding algorithms(Layer II and Layer III), before FFT transfer, there are 1152
samples collected, but only 1024 points FFT are employed, what shall we do with
the remaining 128 samples, just ingnored or shall overlapped by Module Reduction
N?
Before FFT an Hanning window is firstly applied.

Best Regards!
