It should be possible to implement a LTC decoder that turns a audio track into LTC binary data. If that succeeded and the data is valid then teh track would very likely have contained LTC. Do i understand correctly that the tracks are LTC or normal audio not mixed? or are there tracks that mix audio and LTC and require seperation ? I think there are several developers who could develop such filter. I could do it, Iam sure paul could do as well. thx [...] -- Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB "I am not trying to be anyone's saviour, I'm trying to think about the future and not be sad" - Elon Musk
