Hello everyone!
I am new to this forum, i have looked around the topics, but have not found=
the answer to my problem, so here it is:
I got these recordings from other people i am collaborating with, and i don=
't know exactly the recording equipment or the recording conditions (like m=
ic-animal distance for example). I get 2 types of odd things in the recordi=
ngs i suspect are artifacts:
- very asymetric oscillogram, and a "smir" on the spectrogram, above an=
d under the frequency band
- a less marked "smir" in the spectrogram, only above the DF, but going=
all the way to the max frequency of the recording, and extra harmonics
The second case looks a bit like what i get with a saturation, but none of =
those recordings are saturated. I thought, the second case might be a "near=
effect"? if the person put a recorder simply too close from the source. Ho=
wever, for the first case, i just dont know!! In addition those recordings =
are from species i have not necessarely worked with before, so i can't real=
ly tell what should be a "normal" spectrogram for those species....
Does anyone of you have an idea of what it may be? And whether i can still =
use these recordings in some way?
Thank you!
Sandra.
