I also have used Focus Fidelity for a couple of years. It’s probably the best audio investment I’ve made and an absurd value, as far as audio stuff goes. Using it in conjunction with Roon is, well, just really great. I use in a 2.1 system in my study and a 2.0, soon to be 2.2 system in my living room. It’s easy, even addicting to use, adjustible to taste, and the sonic improvements are not subtle.

Hi @Magnus
Thanks for the feedback, I appreciate it.
The correction level should provide a wide enough range of adjustment, each user will find their preference. The default value of 8 will be too high for some as you have found.
Finer adjustments can be achieved by adjusting the target curve, for example, if the sound has too much energy at 1kHz that could be solved by using the movable points on the curve to create a dip in that region. Typically, though, this kind of fine adjustment isn’t required. A smooth target curve will work best with a wide range of music.
For microphone positioning, the advice from the manual is,
The first measurement you will perform is at the main listening position. This position is the “sweet spot” of the listening area where you would typically sit for critical listening. The microphone should be at the height your ears would be.
You should arrange the remaining positions symmetrically around the main listening position with variations in height.
The measurement positions should cover the intended listening area, for example, the width of a sofa.
You can use a tighter spacing between the measurement positions for a single-seat listening arrangement.
There is no exact science to positioning the microphone; however, a total of 8 to 10 measurements will provide enough data.
I don’t have advice beyond this really, the idea is to achieve a good sampling of the intended listening area.
Good point about the default number of measurements, an odd number makes more sense.
The software places various limits on the optimizer to avoid excessive excess phase correction and limited filling of holes/dips.

Hi @MilJL87
The fine time alignment isn’t really required in my opinion but is there as some users like to see the left and right channel impulses perfectly aligned to less than one sample period.
