I have written about this in the Csound forum; however, this
list seems to be a bit more active.

I have been experimenting with cross synthesis / resynthesis in
a number of forms.  The one opcode I cannot get to work is
'adsyn'.  Not only do my attempts produce mostly noise -- to
date, no example I have found has worked, even from the Csound
Book or the manual.

I have included four files as forensic evidence:

1. hetron.csd, an example.

2. innabar.wav, the source file for resynthesis.

3. innabar.het (for what it's worth -- it was built on Linux, so
you know... but if there's evidence in the file, I figured it
couldn't hurt.)

4. maladsyn.wav, the horror-of-horrors output.  Warning: view
this file in an audio editor first, then turn down speaker
volume before trying it out.  It is almost entirely noise.

I am told the very same files I've tried work in Csound 4.  I'm
using Csound 5.08 (Ubuntu Linux 7.10).

Any help appreciated.  I just can't leave the mysteries alone.
