Hi Yash,
I have some questions regarding PS in eAACPlus Decoder.
Are you using/familiar with 3gpp's eAACPlus ?
Could you please tell me in which Q-point format the PS Decoding works in 3gpp's implementation?
I am trying to understand 3gpp's eAACPlus decoder.
Can you please explain to me about the scalefactors which came from the SBR part and you modify the data according to that in the PS decoding.

I have not yet looked into decorrelation optimization so, not able to answer your question but surely i can look into it and discuss as I will also have to do that in next few weeks.


Thanks,


dev
