two audios out of sync

[Malick]

I have HD DVD and DVD with the same movie. I need to replace the audio of HD DVD with DVD audio but they are out of sync. I took 50sec of each from the beginning. Can Someone tell me how many ms they are out of sync? Thank you

Samples are in here - http://www.mytempdir.com/1375395

You must learn how calculate the desync.

At least put samples that contain the same sound, in ac3 format instead mkv container, to make more easy the job.

ok but how to calculate?

[tebasuna51]

- Extract the ac3 from the mkv (AviMuxGUI, ...)
- Decompress the ac3's to wav's (Azid-BeSweet, ...)
- Use an audio editor to compare the two samples (Audacity, ...)

how to i use Audacity to compare?

Search a identifiable peak in the first sample and write the time value.

Search the same peak in the second sample and subtract the times.

With your actual samples don't exist the same peaks.
