Hi all,
I would like to ask you regarding MDCT specially ,as we know MDCT is
DCT (type-4) with 50% overlap on consective block applied in MPEG-4 AAC
low delay.I could not get proper understanding how it works internally.
Example:
MDCT =[ DCT(type-4)* TDAC * Window ]
Cosider for example we have MDCT of 2n inputs and n outputs and this n
output is equal to DCT (type-4) inputs..
I would like to know how this is mapped as inputs to DCT(type-4) and how
TDAC is avoided..
I have gone through the web site as mentioned above
http://en.wikipedia.org/wiki/Modified_discrete_cosine_transform.
I would like to have better and clear explanation then this.Please
give some web sites or book names which will be available with this topic.
Thank you,
Deep
