The HD music fft atlas reference thread

Just below 16 kHz. Probably a blood-laden, pregnant mosquito. I wonder if those numbers on the vertical axis could be made any smaller?

HA!

The picture is quite big so if you open it via the attachment you can zoom into its full size and easily read the axes. But I think you know that already...

My CD rip has a slightly higher dynamic range than my 24/96 flac download.

Mani.

Interesting...thanks for the info! I really don't get what they're trying to achieve by compressing these recordings more and more.

OK--Here's the first movement of the Kleiber Beethoven 5, that I ripped from the DVD-A. Compared to the one from HDtracks posted a few posts above, there's no ultrasonic DSD noise, for one thing. Not sure what's going on from about 7:10 to the end, though.

Here is the HDTracks Allman Brothers Eat a Peach Blue Sky. Great album, but this is another questionable looking spectrum.

I used Goldsdad's service to format the attached the files.

Here is the HDTracks Allman Brothers Eat a Peach Blue Sky. Great album, but this is another questionable looking spectrum.

Looks like originally 44.1 PCM material put on SACD and this one converted from the SACD's DSD data.

This is about as perfect a hi-res spectrum as I've ever seen. It's the last movement of the Bartok Viola Concerto from a brand-new recording of Bartok's Violin & Viola Concertos with James Ehnes on Chandos that I just downloaded from The Classical Shop. Would that all hi-res recordings be as clean as this one!

Also from Chandos (via The Classical Shop). This time it's the first movement of the Bartok Piano Concerto No. 2 with Blavouzet (from an album of all 3 Bartok Piano Concertos). Another really clean spectrum, with great HF extension.

Solo piano this time: Liszt's "Annees de Pelerinage" with Lortie. (This spectrum is of the "Orage" movement.) Think a solo piano has limited frequency range? Looks like there are definite harmonics approaching 40kHz in at least one spot. (And it does sound great as well!
