That is not a locomotive noise, it is a fast forward/skipping audio noise. Are the audio files .aue as I suspect they are? If so, they aren't decoding due to the protection on those discs.

The files were .apx files. I renamed them to .aud. The first 2 minutes always decode fine, afterwards it's all full of this. You think anything can be done about it? I googled and the movie is from 2011, so you may just be right about the encryption.
Tom, what film is it? We may have to find a way to do this.
From the Film-Tech Forums:
I think APX was the file format for a disc watermarking system that was being tested back then. The discs were individually watermarked, so that if there was a pirated copy of a movie that surfaced on the internet, and the audio was captured from a DTS disc (either by recording in the auditorium or tapping the analog output), a forensics team would be able to identify which disc was used on that playback.
It was pretty cool technology, but in the end cost prohibitive and never saw a rollout.

Interesting. Though I doubt this noise is purely watermarking, as it is .... fairly audible.
Fairly strongly audible.
If you want to send me the audio via WeTransfer I can check it out.

Okay, I'll do that when I feel a bit less lazy!
