hi there, thanks for looking at it for me, I really apreciate it...
Im not sure wether this problem might be indeed the DC offset, it seems that is a particular problem with pd looping stuff around. This is because it's a quite drastic click that I do not hear when I loop it on Sound Forge...
Do you know what I mean???????
anyway... I tried a high pass filter on sound forge, and it didn't work that well, it kinda made it click when it didn't...
As for the spectrum loop and timbre change, I see what you mean, I will try to do it, I couldnt invert the phase so far.
cheers

What I notice looking at it in the editor is quite a bit of VLF, there's
a wobble in there at about 2-4 Hz. Very low
frequencies tend to give you
a DC offset mismatch wherever you cut it, so try high passing it at
above 20Hz.
Also, there's a bit of movement in the spectrum up top, quite a noisy
effect that might be making it difficult to loop without an apparently
sudden change of timbre. There are two ways around this. One is to make
a crossfade of 3 sections, mix them down and then cut it 1/3 of the way
from each end, the start and end will have the same spectrum. The other
way is to double the length of it by copying, reverse, invert phase and
insert append (you get a symmetrical forwards - backwards loop that starts
and ends on the same spectrum)
