Hi everyone,
I haven't posted here before, but I've been following this forum for a few =
months now. I am finishing up my Master's degree in conservation biology, a=
nd my thesis is a dialect study of the Nelson's Sparrow (found on the coast=
of New England and inland from North Dakota up through interior Canada).
I just returned from my field season, recording sparrows in multiple locati=
ons in Maine. I'll be analyzing my recordings using Raven, and one of the f=
irst things I noticed when I opened it up was a strange white space underne=
ath the song, which roughly correlates with amplitude and pitch. It looks l=
ike a white echo - a silent space in a background otherwise full of traffic=
and wind noise. Since I know that the traffic and wind noise didn't disapp=
ear, I'm assuming that it is not really there? "I uploaded a picture and so=
und clip in the "File" section of the Yahoo Group in a folder called "Nelso=
n's Sparrow").
The white space is always there to some degree, but it is much more extreme=
in the loud songs, in which I can also hear a little bit of a bubbling sou=
nd (hard to describe). My only idea is that my gain was turned up too high =
and that distorted the sound at times?
I realize that I don't have all the right vocabulary or a deep understandin=
g so this might be hard to follow - does anyone have any thoughts or ideas?=
Thanks,
Laura H.
