LaserDiscs needed for replacing BD audio

[deleted user]

I've never done anything like this, but what happens when you split the captured wav where the parsing breaks and try parsing the split off parts separately?

Well, I have done it before, and, as I converted the DTS from 44.1KHz to 48KHz, I avoided the hassle to join separate sides without loss!

@BusterD: read the thread on OT; you can also make a comparison, but if they are identical, it doesn't mean they are bit-perfect! Still, according to my experience, if you can convert to DTS more than one minute, then IT IS bit-perfect.
Why it didn't convert it until the end? Most simple question is there was a "glitch" somewhere; maybe the capture program has missed a frame, or the disc has a dirt spot and the laserdisc laser can't read it perfectly, or maybe the cat jumped over the laserdisc player and you haven't noted - it happens, it happens...

BusterD,
Have you syccessfully captured laserdisc DTS before? I'm wondering if the side break is interfering with the parsing of the dtswav.

This is my only DTS LD, haven't had any problems with BeSplit on any AC3 tracks so far, though.

I actually tried splitting the wav file into each side, but BeSplit still stopped before the end of side 1, and it stopped about 20 minutes into side 2.

Will try capturing it again someday, if all else fails I can try splitting the file at each point where BeSplit stops or eac3to gives an error,and then stitch it together again.

Thanks all for the responses!

Good luck with the second attempt, if it happens again then it maybe the disc itself. If you have an A/V system give the disc a spin and see if you experience any kind of audio dropout at those timecodes.

[BusterD]

Yeah, I considered the disc being a problem, but I was watching and listening while it was capturing and didn't notice any problems. I guess it could be a sensitivity issue or something.

I would love to get the LD DTS audio for the sci-fi film Mimic.

on a lot of the older Paramount and Fox DVD's they include a 2.0 DD track, and some of these are the original theatrical mix!!! I find that when i convert the DD to MP3/WAV/OPUS it gets rid of the Dialnorm/DRC, and it plays it's normal volume.

DialNorm only kicks in if your AV Amp is set to night mode. If not, it will always play at normal volume.
Also depending on the software you use to transcode from AC3 to MP3/WAVE/OPUS, it may not truly remove the DialNorm, but actually apply it and then transcode it to your chosen output format.

i use Foobar2000 and Handbrake. One way to find out if the dialnorm has been removed is if you compare the DTS version (if applicable) of the same title to the AC3 to WAV/FLAC transcoded version (unless it is a different mix a la Top Gun Special Collector's Edition/3D 5.1 True HD (the 70mm mix) vs the 6.1 DTS HD Master Audio (a more recent Remix). If you can't tell the difference, that means that the Dialnorm/DRC has been stripped.


I have found out that MPC-HC does not apply DialNorm/DRC to AC3 tracks, but VLC does. On my Kodi Android box it doesn't apply dialnorm to AC3 tracks (but on the PC version of Kodi, it does)

I would wager ffmpeg removes it too.
