I would like to plot a spectrogram of a sound between a range of frequencies, specifically from 0 kHz to 2000 Hz. Using SoX (sox sound.wav -n spectrogram -x 1000 -y 800), I have been able to make a plot, but I have not been able to set the vertical frequency axis to the range I require:

How might this be done? I am happy to use a different program.

    What have you tried? Your sample just sets the graph size. I'd expect things like rate, and -X -Y might be applicable. – ubfan1 Jun 25 '21 at 18:07
  • Thanks for your suggestion. I have looked at SoX documentation and -y changes the height of the image produced while -Y changes the height of the plot as it appears in the image. Neither changes the limits or range of the vertical axis for frequency. I've confirmed this in usage tests. – BlandCorporation Jun 25 '21 at 18:26
  • Stick in -r 4k in front of sound.wav -- works for me to reduce the vertical frequency to 2k (one half the sampling rate). – ubfan1 Jun 25 '21 at 21:50
