Attention Fellows and Madams,

With regards to adsyn synthesis of hetro analysis:

I've analyzed a piano note with hetro (using up to 50 partials).  Upon
resynthesis in adsyn, the resynthesized piano note is not as close to the
original as I would like.  The attack of the note is not as sharp (ie less
transient detail) and there is both low frequency and high frequency
distortion.  Any ideas on how to improve the quality of analysis to obtain
a more accurate spectrum?  Or is adsyn not capable of recreating the hetro
output accurately?

What could be the source of my problem and how could I fix it?

I welcome any wisdom on the subject.

Thanks,

Greg
