- smacke 8y agoInteresting! I was not aware of that project before. It looks like it could be worthwhile to incorporate their neural net-based VAD, if it's not too slow. At a first glance, it looks like the main difference is the postprocessing step -- they use some heuristics to avoid trying all possible alignments, while subsync uses FFT as its secret sauce to get away with trying out all of them. :) I should include in the readme that for >1 hour movies, it usually finishes the synchronization in ~20 seconds, which compares favorably to the project linked in your comment (13 minutes unoptimized, 2 minutes optimized).
