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,
See ?spectro and its "flim" argument:
spectro(x, wl = 256, grid = FALSE, osc = TRUE,
listen = TRUE, flim = c(0, 10))
