Hi Folks! Just needed some information on some of the schemes that are used to implement DeQuantization of audio samples. The scheme that I know is DeQuantization using a look-up table of 8192 by storing the value of y^(4/3) in the table and using y as the index to access these values. Is it possible to eliminate the Look-up table totally without much computational

Hi all, I am Mynampati Kuldeep.I am doing a thesis on Low Delay Filter Banks. In MPEG-4 ER AAC, due algorithmic procedure a delay of 20 ms is present.So,this delay is to be further reduced modiying Filter banks.I would like to ask you to suggest me some Information ,or web sites or some articles regarding this. Thanking you, bye... mynampati kuldeep kumar

Hi All, I am presently working on MPEG-4 HE-AAC. I faced problem with _twi(Twiddle)series,while i am doing the conformance testing. The vector is showing that its of AAC MAIN profile.But my decoder supports only AAC LC profile. So,is it necessary to test my decoder with _twi vectors? And also which series of vectors are sufficient to test Sbr part. If any one knows about this please mail

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) i
