How to use eac3to to edit AC3 to avoid transcoding

That and the 44.1kHz sample rate, although there are DTS audio CDs as well

Is editing DTS (not HD MA) supposed to be lossless?

Simply cutting the beginning appears to have filtered out the high end at around 20KHz for the rest of the track. How can this be?

EDIT: I wonder if its just Spek reporting it incorrectly. Because it seems way too quick for re-encoding to occur.

Just a thought but is this laserdisc DTS you are editing? If so have you used -dontpatchDTS?

It is a laserdisc DTS! But I also used -dontpatchdts.

Whats weird is if I cut only a small value like -60ms it looks fine. But if I cut a large duration like -50000ms it filters the high end. Very strange.

Hmm. That’s concerning. I may have to go back and find my raw recording files on some of my rips and compare.

Riiiight so the problem is just Spek's rendering. If I increase the window size so that it re-renders it looks all good.

I feel so stupid haha. Don't need to go back to recheck borisanddoris, nothing to worry about!

Great news. I didn’t want to have to go back and redo all 3 hours of the boat movie.
