  44.1kHz to 48kHz laserdisc PCM track conversion
Posted by: spoRv - 2021-10-05, 02:53 PM - Forum: General technical discussions - Replies (12)

It is common ground that the simplest way to convert 44.1kHz laserdisc PCM track to 48kHz is to capture it via digital cable by a bit-perfect audio card, then convert it to 48kHz

BUT

this introduces a very tiny error in the signal

AND

if we slowdown PAL to NTSC (or speedup 23.976fps to 24fps) we introduce further quality degradation

AND

if the PCM on NTSC laserdisc is not 44100Hz but 44056Hz then any bit-perfect capture is, well, not perfect!

THEN

why don't we capture at 48kHz 24bit both analog and PCM tracks via analog cables?
  • no quality loss converting 44.1kHz to 48kHz
  • less quality loss converting from 25fps to 23.976fps - or 23.976fps to 24fps
  • if the laserdisc NTSC PCM frequency is really 44056Hz then capture it digitally at 44.1kHz, bit-perfect or not, is futile - unless it's possible to capture at 44056hz bit perfect

sure, it depends all from the player's DAC quality but AFAIK mid models had good DACs, up to excellent ones on top and high end models.

We must find out if a laserdisc PCM track taken from a good/excellent player's DAC analog output captured with a good audio card at 48kHz 24bit is better than a digital output captured bit-perfect at 44.1kHz then converted to 48Khz 24bit (24bit to be eventually edited - I'd always release at 48/16); I'd also add to the equation the PAL/NTSC slowdown affaire - even if PAL laserdisc market was much smaller than NTSC, we are still talking about several thousand titles...

Thoughts?

  The Wizard of Oz (1939) 1989 LD Isolated Music and Effects Track
Posted by: James76 - 2021-10-04, 08:54 PM - Forum: Requests, proposals, help - No Replies

Hi,

I was wondering if anyone had done a bit-perfect rip of the isolated music and effects track from the 1989 MGM/UA LaserDisc of The Wizard of Oz. I would like the track to be a PCM WAV file so I can mux it to a rip of the 1999 DVD (which I own), and I would like the track to be sync-able to the rip. I don't have the 4K Blu-ray release, since I don't have anything UHD-related yet.

Thanks!

  DTS Stereo, how many channels?

I want to find out if the japanese movie (not the remake) "Dark Water" (the Arrow release) has the original mix. I suspect it's a remix.

DTS Stereo is 5.1? I don't think so, and I think must be LPCM 2.0 stereo. Am I right?
