I hesitated to spend $20 on an app, but this seems to provide a great deal of control. I haven’t a clue, yet, how to use it, so I’ll be looking for online tutorials. I expected to find an EQ or similar controls, as so many had suggested AudysseyMultEQEditorapp due to the lack of manual control while using Audyssey. I’m sure I can do this with the curves, but I’ll have to learn how.
On Nov 19 (it doesn’t say what year) “TOJOHNSO” posted a reviews here about the value used by Audyssey to calculate speaker distances. I was skeptical, but I used his math (multiply Audessey values by 0.875) in AudysseyMultEQEditorapp to change the calculated distances… what a difference it made! I run Tidal through WiiM Pro Plus with fixed volume, mono off, at 100% volume into stereo output and the change was very noticeable - much more depth and volume. After hearing this improvement, I grabbed a tape measure and entered actual distances for nominal additional improvement.
I’ve still got a lot to learn about adjusting curves, but I recommend starting with this adjustment… which can be done without AudysseyMultEQEditorapp .
