A color scheme more similar to the Praat grayscale can be achieved using the `col` argument and the `:gist_yarg` color scheme. These spectrograms are created using the `heatmap` function from `Plots.jl`, so [any color scheme available in the Plots package](https://docs.juliaplots.org/stable/generated/colorschemes/) can be used, though not all of them produce legible spectrograms.

A narrowband style spectrogram can be plotted using the `style` argument:

And, the pre-emphasis can be disabled by passing in a value of 0 for the `pre_emph` argument. Pre-emphasis will boost the prevalence of the higher frequencies in comparison to the lower frequencies.
