Currently the amplitude spectrum being plotted is the amplitude spectrum for a single trace only. The spectrum should probably contain frequency content from several traces, sampled along the line, either regularly spaced or randomly. This may reduce the chatter in the appearance of the plot.

Other options to smooth the spectra include, using a smoothing filter on the array, or using Welch's method https://github.com/kwinkunks/timefreak/blob/master/basics.ipynb
