very similar but.... on the loud bits

 

 

Not clipping according to Audacity but right on the limit more often than with either Cd copy

 

 

Keep in mind that there might be intersample clipping. Audacity does not display the real waveform so you can't see it.

This is how extreme intersample clipping looks like:

 

 

Back to topic. Benchmark Media Systems published this article on the bit depth stuff:

Just a little intrusion here, to tell that the 16-bit v/s 8-bit blind test page that has been often cited in this thread, has been updated. Now using Neil Young's own music. I am such a bad guy indeed...

Genius. I am glad you are going there. I look forward to the result.

I've started reading and advanced well through pages 1 tot 20. then I started skipping some parts of the thread, ending up reading the last set of pages (boy, what a job, let alone the fact that some clicking to referenced pages need sto be done too).

 

What I already knew got confirmed now in a scientific way. One can indeed show and proof technical / theoretical (show meaning either audible or (mostly) in statistics) differences between different formats, both in dynamic range (bit depth) as in bitrate (the sampling).

 

Fact is that for real life use there are very little musical works that could benefit from any of these differences, because of a bunch of limitations in the chain (production, reproduction, sensitory system and psyche of the listener).

 

My concerns were at the stated "subharmonics and overtones, 30K cymbal stuff and some more of those together with the influence of the sampling into the lower frequencies (teh last one been shown to be able to sometimes even worsen the final result).

 

Considering phono... there's more to it than just LP DR figures: RIAA curves and preamp rumble filters with low frequency rolloff have an impact on the final sound shaping. Anyhow, a good player attached to a nice set of preamp-amp-LS has very little hissing or noise (same goes as above: crank up the volume and hear the noise, and next when the music kicks in hear a beep... :) ).

 

As for commercial reasons: I got a recording from the library last week, SA-CD. So I was figuring: let's give it a go for some hi-res testing. No need to, because after a simple check on my laptop (Audacity) it turned out to be 16/44 material.

 

So I'll leave it at looking for good quality material (starting at good recording and mastering and decent pressing/burning/ripping) and enjoy music at 16/44, or eventually - but not necessarily - higher.

Your computer was reading the CD layer. SACDs (which are encoded as DSD) can only be played in authorized SACD players and ripped by early PS3s. So yes, of course the files you got were 16/44.1.

It's a convenient test but somebody criticized the test because it ain't high DR content. (Or something.) But that obviously didn't get the guy to conduct his own Foobar abx test.

The page itself says that you can readily hear the effect of 8-bit, but that the effect lessens with much popular music, exactly because it often isn't high DR content.  It would be interesting to have an example of, say, the ending of Mahler's 6th in 16-bit-noise-shaped vs. 24bit.
