Body: <p>I'm trying out producing some spectrogram videos in R for presentations and sharing through av_spectrogram_video (from the av package), but would like to crop the spectrogram to zoom in on lower frequencies, this doesn't seem to be an option in the plotting function - does anyone know a better way to do this or another package?</p>
  <p>Thanks</p>

  I'm trying out producing some spectrogram videos in R for presentations and sharing through av\_spectrogram\_video (from the av package), but would like to crop the spectrogram to zoom in on lower frequencies, this doesn't seem to be an option in the plotting function - does anyone know a better way to do this or another package?
  
  Thanks
