Wil,
Yes, my thougt about the wind was wrong. The normalizaton was the problem. =
However the ambiance where the nightingale sings is louder than the ambianc=
e where the emberiza calandra sings. The first ambiance was wet and with a =
lot of vegetation, the other one is like a desert, withou water only some c=
ork trees. Now I know I can't normalize without listen carefully first.than=
k you.
