danadam replied to the thread Is this normal behaviour for dacs?.For anyone who actually wants to read I'll repeat what I wrote earlier: Here's 1 kHz tone in 16-bit / 44.1k sampling rate, using FFT... -

danadam replied to the thread Is this normal behaviour for dacs?.Actually I got it slightly wrong. After reading The Signal Chain: How do noise and distortion propagate through my system?, it's more...
-
danadam replied to the thread Is this normal behaviour for dacs?.It's only an indication that the distortion is lower than the noise. And because the noise is so high, we can't tell what exactly the...

danadam replied to the thread Testing audiophile claims and myths.Nice of you that you protect the anonymity of whoever wrote that :)

danadam replied to the thread Is this normal behaviour for dacs?.Why don't you show distortions computed by REW? (first button at the top: "Show distortion") And then I would suggest to configure REW...

danadam replied to the thread Some Test Tracks to check for Absolute Phase!.Such tests should: either hide the current score until you decide you are finished, or ask for the number of trials before starting...

danadam replied to the thread Sound Science Corner Pub.Yes, and I can see everyone mostly agreeing, that it is audible with some kind of signals. I very much doubt that this was the reason...

danadam replied to the thread Is VST band-limited?.These are aliases, not images, and they are there regardless of what DAC you use. When you play this file on a NOS and filterless DAC...

danadam replied to the thread Is VST band-limited?.Yes, and if the 12 kHz square wave was properly created you should get a pure 12 kHz sine wave. But with the way Audacity created it...

danadam replied to the thread Can you hear upscaling?.I'm using SoX for nearly everything. For generating the band-limited square wave I have this script, which uses SoX internally. Earlier...

danadam replied to the thread Can you hear upscaling?.Somehow I'm not surprised that you would think that. It's actually all the frequencies: I'm worried that you'll take it and...

danadam replied to the thread Can you hear upscaling?.I generated this impulse at 352.8 kHz: The left channel is delayed by 1 sample (2.8 µs). I converted the file to 16/44k: I played...

danadam replied to the thread Speed of Electricity in a Cable.More relevant? I guess that depends on what weights you assign to the attenuation (due to the inverse-square law) vs duration of the...

danadam replied to the thread Speed of Electricity in a Cable.Inverse-square law I presume.

danadam replied to the thread Speed of Electricity in a Cable.Almost (or exactly) like "stairsteps" in digital audio :-)
