hi,
In aac lc profile i just tried to decode the raw data stream manually.
In standard it states that we will get the spectral values till max_sfb, which can be less then num_swb(table 8.4 - 8.16 of mpeg2 aac).
So i got 640 spectral values after hufmman decoding. BUt for doing IMDCT we need 1024 samples.
Can anybody pls tell me what we should fill in the remaining spectral values.:
Pls tell me where in the specification does this is mentioned
:thanks: in advance.awaiting earliest reply
