    The relevance of measurements to audible quality of sound

    College level texts on hearing or senses might be a good place for you to look. Lots of basic info in one place. It may not be pre-chewed enough. You'll find spending some effort earns large dividends. Some is not directly related to things like THD or reflections etc. But enough is so...

    MQA: A Review of controversies, concerns, and cautions

    Yes very interesting is it not. If at first you don't succeed, then try, try again VS if you don't study history you are doomed to repeat it. There really is no substantial market for hires. Wisdom of the masses and all that.

    Dac Testing: Incompatibility of ASIO4ALL and Windows 10

    That explains a laser printer which was working fine, and now doesn't. I had to find some obscure illicit driver. It wouldn't use the original one on the disk which was maybe Vista. It wouldn't find a new one that worked correctly. The new one worked, but messed up formatting badly. Over...

    Steve G incites new rage in objectivists!

    Just to be clear, I was referring to digitizing an LP and then comparing the ripped file to the LP. Now I've also done an LP, reel to reel and CD comparison using all pre-recorded sources. That was a long time ago. Several of my friends were involved. The big surprise was that CD and rtr...

    Steve G incites new rage in objectivists!

    I've done this informally. And you know what? Some people could detect 44 khz, but not 48 khz or 88 khz. I suspect the moving coil in use is the reason. I know it has a resonance around 22 khz.

    The Spirule. How many of you .......

    Never heard of the Spirule. Closest thing I've used is one of these: To make this sort of thing: I have a couple old slide rules. A very elegant and useful device for the times. Of course I was young with good eyesight then. Now, I'd need the one at the front of the algebra class I had...

    The relevance of measurements to audible quality of sound

    I would like what the OP is asking for, but things are complicated. Where I live an F health rating gets you shutdown. So only C or better places are open for business. And the Op wants something like that for audio. Buy this component with this fidelity rating of C or better and you'll get...

    Review and Measurements of ifi nano iDSD Black DAC and Amp

    @amirm It would be more work for you, but could you do the following. Record some 30 second segments of a few music selections for each DAC you review. My suggestion would be to record at 96khz the DUT playing at 44 or 48 khz. This way people could download and listen for differences in...

    Better translation: "To you, the great Not-to-Be-Named, signs of the black stars, and the seal of the toad-shaped Tsathoggua".

    New report from the global scientific authority on climate change: Planet has only until 2030 to stem catastrophic climate change, experts warn.

    https://www.telegraph.co.uk/news/2018/10/04/david-attenborough-says-bbc-still-needs-white-men-explaining/ Yet even if your allegations are true, and they seem to me largely to be so, that doesn't by itself invalidate climate science.

    The relevance of measurements to audible quality of sound

    A good example where sometimes you need to dig deeper than single numbers. Most mikes probably are closer to 16 db self noise than 26 db. And most can work cleanly to more than 130 db. Most would have a full dynamic range of 120 db or more. Though truly other than super close miking (not...
