This brought up some question and ideas in my mind.
Craig had some specifics in his video, that he needed a cut around 200hz, add in some high end from around 1.26Khz and a bit more around 1.46K to the end and put in a cut around 2.7khz. How did he know all this? Well he was probably looking at the graphs in channel view and using his knowledge and experience.
What if you don't have the ears, experience, and vast knowledge of Craig? Or what if you're getting a bit older and maybe don't hear as well as you used to and aren't as skilled at looking at the graphs? Maybe Landr is a good way to go.
Then there's the dreaded har-bal! I have used har-bal for a while and wanted to see what it could do. So I took the first song off Craig's video and pulled in the unedited version to see what I could find. Here's har-bal's graph of it.

https://drive.google.com/...view?usp=sharing As you can see from har-bal's analysis. There is indeed a big peak around 200 hz, it looks like it might be centered a bit before 200hz. It also clearly shows a low point that starts around 800hz and extends to about 2khz but with a peak in there around 1.2khz and again around 2.4khz with the high freq tailing off from around 4khz to the end.
In my view, it clearly points out that Craig's analysis was exactly right, but also gives more detail as to exactly where things need work.
It took me about 2 minutes in har-bal to modify it to look like this on the graph.

In the 2nd pic I corrected this to -14.14db. This was quickly and easily done in har-bal's histogram view raising the level to just before compressing.
This was all just an experiment on my part to compare Craig's findings in the video with what I could discover using har-bal. Is it going to replace a Craig or someone like a Bob Ludwig? NO! Is it an easy way to quickly make big improvements to a song and possibly understand what needs work? YES!
Here's a link to the file processed by har-bal if you want to compare to the ones on Craig's video. You'll notice there isn't the added reverb from Craig's job as that's not something har-bal does.
