I just listened to a couple of your samples and viewed the spectral
display of them.
In general you already filter harder than I do.
My duck sample in a post below was filtered hard which I resist and
for my work the goal is not to record a sample for use in "manmade
created natural soundscapes". I've done a bit of that and will be
doing another composite soundscape this summer. Then I do have to
noise reduction at a 40db level to build a bite for a segment. but I
hate doing it and I prefer to leave natural backgrounds in when
editing species ID stuff.
What I do is rate my recordings in A,B,C,D. "A" is a recording that I
feel is better than what I hear on large scale published CD's for
species ID purposes. It is a recording where I can say "Lang, I beat
you". A "B" recording is a recording where it has defects but it is
still in the area of being "published" and sounds of this quality are
often published. "c" has major defects and is only offered as an
illustration of the sound. "D" is were I am desparate and the sound
has value but the recording isn't going anywhere.
