Software for measuring/correcting lip sync audio delay?

[Selur]

I just remembered, maybe https://gitlab.com/EleonoreMizo/faveworm could be used:

core.std.LoadPlugin(path="%FILTERPATH%/SourceFilter/BestSource/BestSource.dll")
# bs.AudioSource(string source[, int track = -1, int adjustdelay = -1, int threads = 0, bint enable_drefs = False, bint use_absolute_path = False, float drc_scale = 0, int cachemode = 1, string cachepath, int cachesize = 100, bint showprogress = True, maxdecoders = 0])
# see: https://github.com/vapoursynth/bestsource
audio = core.bs.AudioSource(source="PATH TO YOUR INPUT", track = -1, adjustdelay = -2) # select first audio track to no adjustment

core.std.LoadPlugin(path="%FILTERPATH%/Support/faveworm.dll")
scope = core.fw.scope(clip=clip, audio=audio, mode=3, sweep=0.20, beam_size=1.5)
import misc

clip = misc.Overlay(clip, scope, opacity=0.5)

not really sure how atm.
