Applying the audio delay is necessary to keep the audio in sync, so the fact that eac3to applied it for you is a good thing.  That is why it is automatic.  As long as the output is in sync, everything's fine.

Removing the dialnorm is necessary for proper decoding.  That's a good thing as well.

Yes.  Unless you have a specific reason to suspect that a problem has occurred, you can edit your tracks now.

It sounds very great! I'm so happy that I did it at all, especially for the capturing AC-3 DD5.1. Thank you very much, Chewtobacca!

Btw, You can capture Bit-Perfect with Quicktime 7 Pro on macOS, up to macOS High Sierra -> macOS Catalina will nuke any 32bit apps

- open Midi Setup and select Build-in Input and select 16-bit Integer 44,1kHz (IMPORTANT: You've to do every time after you've rebooted your system)
- open Quicktime 7 Pro -> New Audio Recording -> press Record
- When recording is finished press the record button again
- Export audio (CMD+E) and select Sound to Wave -> Options: Stereo, 16bit, 44,1kHz, Best Quality -> press OK
- Save audio at your preferred location

This was tested using a DTS Audio CD and DTS Parser (Windows App) and the final result is a proper DTS file, hence Bit-Perfect

I never good this too work in Adobe Audition or Audacity. However, I can confirm using Cockos Reaper will also give you Bit-Perfect on macOS.

Apple Logic X (tested with v10.4.4) is also capable to capture Bit-Perfect

I'm trying to follow bronan's guide, but I keep running into an odd problem during recording. 

I set Reaper up as instructed, press record, start playing bronan's DTS Test Kit CD, and it all seems to go fine for about a minute. After that I realise that the time counter on my laserdisc player has overtaken Reaper's track counter. By the end of recording the laserdisc player has played 4:14 but Reaper has only recorded around 3:58, despite the recording starting before the CD. 

My soundcard is a Creative SoundBlaster SB0880 X-FI Titanium. Below are screenshots that I think show all the relevant details for the card and Reaper. 

I'm pretty new to audio hardware so I may be making a really obvious mistake, but if anyone can help set me right I'd really appreciate it.

EDIT: I just noticed that in the Reaper Preferences screenshot I posted the Enabled Inputs show "Not Connected 1" and "Not Connected 2". When recording these read "Digital-In 1" and "Digital-In 2". See third screenshot.

That's weird, everything looks OK. Perhaps try another protocol besides ASIO?

This is the first time I've tried recording using Reaper. My previous LD PCM rips were done using WaveStudio, it isn't as configurable and is meant to just do what the sound card tells it to do. I didn't see the same problem using WaveStudio but I've also not been able to pass your DTS CD test using that so wanted to try something more accurate.

I'm away from my computer just now, but when I get back I'll try recording from a laserdisc into Reaper to see if I can hear any kind of skipping or speedup, for some reason I didn't think of that earlier.

I'm using ASIO4ALL because Creative's ASIO driver sadly has a problem with this card at 44.1 kHz. I'll experiment with different protocols too. Any you recommend?

Thanks for the help.

Started up Reaper again and for some reason this time ASIO4ALL automatically popped up it's settings dialog and I instantly spotted the problem. ASIO4ALL has a setting called "Always Resample 44.1kHz <-> 48kHz". Why this is enabled by default I have no idea, but disabling it allowed me to finally hear that sweet elevator groove from the DTS CD! 

Sorry for troubling you, I really should have spotted this myself, but I'll leave the posts here in case they're useful for anyone else using a similar setup in the future. 

From here on I can happily claim my LD PCM rips are bit-perfect!

No worries, nice find!

This will not work in macOS Mojave!

While QuickTime 7 is still working, the OS however no longer lets you gain access to the audio inputs. The OS will ask to use the microphone (include digital in) for QuickTime X but not for 7.

This really sucks!
