Good afternoon,
My name is Thiago. I'm a graduate student and affiliated to an Anuran
Bioacustic and Systematics Laboratory at UFU (Federal University of
Uberlândia) in Brazil. The professor in charge of the lab (Dr. Ariovaldo
Antonio Giaretta) and I have recently been making use of R, specially the
packages Sound and Seewave so as to analize anuran recordings. This software is
just fantastic, but I am writing to ask for help about the graphics generated
by Seewave. A graphic and the script I used are attached to the e-mail, so that
you are able to verify if it is possible to reduce the graphic scale of the
Y-axis (see we need only until 10 KHz, even less than it). The fact of
recording at 44100 Hz/16 bits resolution may be a possible cause for such a
long scale, but that is the only way to record with the best quality... If
you think it is easier to change my script and send me back, I would reallly
appreciate it too.
I am looking forward to your reply.
Thanks beforehand,
