Thanks for the comment! Audio is definitely an interesting angle. We haven't spoken to a lot of folks yet that want that feature, but I'd guess some productivity tools that let you rewatch Zoom calls, baby monitoring, media playback, or a few other things like that might mind audio useful. We'll explore it for sure.
We currently process on the per-frame basis but have the optionality to increase the window size of 1, to any arbitrary size like 300 frames. This is what allows us to currently detect "actions" for some of our customers. Of course, it's not the same as a sliding window but it's something we're considering.
