Anyone knows how microsoft AEC can deal with mismatches between clocks of capture and render streams?
Hi All,
Many Thanks to Underwood for her excellent review of our big trouble which prevent LMS-based AEC algorithms to be used in most computer. Maybe it can be summaried as follows:
1. Different sample rate of sampling and rendering does exists in most low-cost soundcards (In my experiments over more than 20 soundcards, the differences range from 0.5Hz to more than 50Hz when sample rate is set

I don't know if this has only recently been put on line, but I never

That paper is from people at MS describing, in some detail, what the
Windows kernel echo canceller does to handle synchronisation issues. It
tracks both time varying sample clock drift and hiccups in the sample
streams. It seems to handle the drif...

...paper-Challenges.
The resampling in the paper-Drift is too coarse. Maybe we can combine the RSO
detection of paper-Drift to the paper-Challenges?
What's your opnion?
