With your ears ;)

It should be obvious when played simultaneously, it would sound off-key if the pitch doesn't match.

Hmm, is this the raw ac3 stream? Is LD ac3 48kHz or 44.1kHz? Was it ripped digitally? Did the capper already convert it in some way?

I will give it a listen LOL and see if I hear any difference,and for the other questions,I am not sure I will have to ask him when he is back online,damn this is just soooo frustrating,I have never seen this before in an audio file.

Thanks for checkin in though,I really appreciate it.
