Sweet Room

I found this thing is difficult to use without professional knowledge.

It does require a lot of knowledge, enthusiastic amateur level for sure. Most DSP has the ability to make things much worse, there is nothing in what they have given us to stop you doing this, you really are on your own, here are the rules I've been following.

1) Based on measurements made at the listening position limit corrections you make to below 500Hz. If your room is large use a lower frequency.

2) Only make adjustments above the cut off freq in 1) based on anechoic measurements, and these should probably only be broad (low Q) tonal shifts.

3) Make extensive use of the ability to switch between the 2 configs whilst listening, find a minimal set of filters that do seem to address the worse problems, then explore adding other 'fixes' on top of them driven by what you prefer. The instant switching between the 2 filter banks is the killer feature of SR, most other approaches (e.g. Roon) take a second or so to switch, which is hard for the brain to follow, so make good use of this, and let your preference decide which is best, but don't rush the decision.
