I used up the Trial Period and the company was good enough to extend another 2 weeks as I was having some issues around syncing two recordings made on different clocks (Zoom F8n Pro and Zoom H6). I found that once I trimmed the clips so that they were close to the same length, Auto Align Post2 did an incredible job.
I only used the dynamic mode on that one source; once I had it aligned to the other ones, I used Fixed alignment for the rest of them. I like how you can decide exactly which source to align to which, and how you'd like that done.
I played around with their original Auto Align software and it's pretty good but I definitely prefer the simplicity and power of this Post version. I'll definitely be keeping an eye out for a sale, as $400 would take a lot of amateur recordings to make it worth it but now that I've used it, I may be spoiled forever.
If you have a show to align that you think may have weird phase or alignment issues, I'd definitely recommend giving the trial version a shot. It's honestly one of the first tools I've ever found for our use case that seems to be more appropriate than plugins made for making music live.
