Whoops, just clicked through to the documentation and it looks like this is the
track you're on also. I'm curious if you have any insight into the
window-

7. overlap-add each frame to get the resulting time-domain signal
See below for more.

It’s maybe worth
Alex,
A number of experienced DSP engineers have spent considerable time
trying to help you understand the problem you're describing, yet it
doesn't seem like you've made much progress. Your questions often seem
to end up with asking folks to basically write your code for you. I
don't want to be
I think the PLL approach will be much more robust, and will let you
detect phase changes.

Looks like an extremely interesting seminar. Unfortunately I'm
US-based and won't be able to make it (though 90 EUR would be a
bargain!).
Will any slides/materials/videos be posted online for the general public?
Thanks,
