Help Wanted: for an... E.T. (1982) - LD PCM Preservation

digitalfreaknyc brought up a search for the 2002 version of the movie and that’s where it clicked for me. i have to get rid of the 7.1 upmix and get the original mix. now before jump and go all nuts, the mix is included on the blu-ray as dts with low bitrate of 448kbps and it sound pretty good. but when a lossy dts can sound good, how would a fully uncompressed track from the laserdisc sound like? well, even better and you wouldn’t have the problems of dts not triggering the proper surround mode, which is exactly what happens for me on the blu-ray sighs

so long story short: i’m requesting the untouched (16bit, 44.1khz) pcm from thx signature laserdisc.

can anyone help out a fellow e.t. fan?

thanks in advance 😃

I believe that someone said an uncompressed PCM track at 41000 basically equals a DTS 448 track at 48000.

A track with a bitrate of 448kbps should sound identical to a lossless track unless you have magic ears. Plus Blurays don't support 44.1khz and you would have to resample the track, which would make it sound worse even if you use the best resampler in existence. (44.1khz does not divide evenly into 48khz).

i have no interest in changing the samplerate or making a custom blu-ray ;)

besides, if going from 44.1khz to 48khz makes the audio sound worse, then all of the ld audio transfer and theatrical dts mixes to blu-ray would sound bad. but they don't :P ;)

Exactly. I've never heard any difference in the upsampling I've done for my laserdiscs.

Shouldn't be an issue. The big difference between the tracks will be in mastering and cleanup. The DTS track is somewhat compressed and will likely be EQ'd, scrubbed for a "cleaner" track but removes fine details and likely dynamic range as well. This is how the Jaws mono seems on both DVD and the BD's DTS version.
