This indicates that these 96kHz files were upsampled from 44.1kHz. The spikes sticking out above the rest are distortion, the result of clipping. A close examination of the end of the fade-outs of the tracks shows they drop in volume from about -90 dB directly to silence, indicating the original files were also 16-bit. If they had been 24-bit originally, the fades would progress from -90 down to about -140 before reaching silence.
Though there wasn't a big deal made about this being 24/96, it does say that in some places online, like the Sony Music Shop, which could be construed as advertisement, the fact is that's misleading and it is actually sourced from from standard CD-quality audio.
Although I don't believe there is an audible difference between 16/44 and 24/96, I still think that's pretty lame. It technically would have been better not to upsample at all, and I'm still baffled as to why clipping ever still occurs at all since all digital audio workstations come with very easy methods of preventing it. |
What source files did you use? Did you rip it yourself or use a rip online? You can't trust online rips as they could be the 441/16 upsampled like the FLAC set that's going around.
I could not rip the disc as it used a newer version of AACS. I do know the files are uncompressed PCM 96/24. Since everyone masters at that it would not make sense to upsample.
Keep in mind if you don't have the hardware for 96/24 you won't hear any difference. I have a 5.1 Pioneer that supports SACD/DVDA etc. and true 96/24 and I can hear a HUGE difference, mainly in bass and high ends but much better.
