[Completed Beta] Automatic timing alignment for Main Speakers and Subwoofer

[slartibartfast]

I have always applied time correction prior to any room correction. However the setup I use is rather complex, using outdoor 'anechoic' measurements for time alignment of all individual speaker (driver)s and subs, then alignment between all of these at the listening position followed by room correction with lower bass frequencies only (the room is acoustically treated including corner bass traps so very little RC is required)

WiiM have already stated that this automatic timing doesn't even try to compensate for phase differences between the subwoofer and the main speakers at the crossover frequency so in my case where the sub doesn't have any DSP of it's own to introduce delay it isn't worth using. It is probably useful if there is an audible delay between the sub and main speakers to get you within a few milliseconds of the optimum value.

What I find ironic was when I got the update I run it and got 27ms. I run it twice and got same result. Today I run it I got 7ms and run it again and got 7ms. What’s causing this variation?

Remember that WiiM indicated they use the tiny "Sync Mic" on the WiiM unit itself. Between the "27ms" and "7ms" measurements, did you move anything in/on your media rack that could have blocked a reflection path from the Sub to the WiiM??

1. That makes no sense, time alignment should be relative to the listener, not a random location in the room.
2. Bass notes would require large, dense surfaces to have any real impact so this is extremely unlikely.

It might not make sense but it is true.
