Inside Your High-Res Music: Sound Liaison high resolution music clips

[amirm]

Hello everyone. Here is another episode in my look inside different high resolution samples. Here, I analyze the free samples from the great indie label, Sound Liaison which as 2L, are kind enough to provide these clips for us to use: https://www.soundliaison.com/all-categories/6-compare-formats

In this look, I examine the DXD files at 352 Khz using another program, MusicScope:

This allowed me to play the files even in DXD and dsd formats.

As before, lots of surprises in this analysis. Issues in both DXD and DSD formats (especially the latter).

Cool.

That was truly excellent.

What I don't get is this statement from the website:

"All the different formats have the same source file, DXD 352kHz (Studio Master)."

So the original, presumably, had the brickwall filter and ultrasonic noise.

But the PCM version lacked a brickwall filter and had a more gentle rolloff.

I don't know how they did that given the starting source.

Noise shaping and dither, I guess?

The test was with track 1 of this album: https://www.soundliaison.com/studio-showcase-series/276-carmen-gomes-sings-the-blues

I am puzzled given the description there how we wound up with what we have here regarding vocal track. They say it was a simultaneous DXD and studer analog recording. All I can think of is that the vocal mic/amp were at fault.

I am puzzled

Probably electrical interference with all the pacemakers installed in the audience.

The DSD versions according to the site are created by running the PCM original through an analog chain not digital conversions.
