[Help] Audio Syncing

[deleted user]

Tom,

I think something similar to your concept is used in the retrosync sound module, except it uses the projected image shone onto a photosensor to create the sync pulses, which can then be used to conform the captured audio to the desired fps.

In reverse there is software called film-o-sync which can lock a digital soundtrack to film playback by using the equivalent of a timecode signal generated by the projector (kind of like how DTS works)

I could do it a bit cheaper than that retrosync sound module, heh. Wonder what algorithm they use for resampling.

Yeah the film-o-sync does the reverse, not very useful to us here I think.
