I hear from all the post that there are many simple solutions to correct Audio-to video lipsync issues, and as stated, most of the time audio is already late. but this device has to have other applications than that, adjusting 1/3 msec is crazy short, anything under 10 msec delay is undetectable, and that's for percussive stuff, for talk it's much more, 50msec, even more nobody can detect a delay... So that kind of precision, what for? maybe more precisely insuring that two sound source are precisely in phase, stuff like that we are more at the waveform, few samples level than correcting lipsync issues here, I am curious what the main reason people buy that. And I am just talking audio perception here, which is many time more accurate than the eyes, let's not forget, 1 video frame is 33 msec....
