Hi Jean-Marc<br><br>I am facing a few problems while trying out the harmonic grouping method. <br><br>The decoder is expected to reconstruct the output from w, ai,bi,ci and di vectors. So these are the parameters which are to quantized. I was expeceting that the w vector would contain the frequencies of the signal accurately or atleast it will haev teh same characteristics as the actual frequencies. But what I observe is that, thought the synthesised signal contains exactly same sines as teh actual signal the frequencies as indicated by w do not necessarily show the corerct values. And the biggest problem is that teh harmonic character of the sine waves is also not observable in the w vector. And I feel that this might make teh qunatization very tough; even if we use some other methods. So even if the initial estimation of the frequencies might not do much harm in the accurate synthesis of the sinusoids ( since we can adjust the freq offset with phase modulation), it might be helpful in qunatizing them.
