    I was listening the other night to a 'Best Of' Creedence Clearwater Revival. Not exactly showcase recordings to begin with and being one of those compilations you buy for a quid from a basket at a motorway service station it is way too compressed. I still enjoyed it immensely though.
    Will dig out a few when I get a minute or two and I can bear it!

    Please enlighten me - thanx!
    Sorry for coming late to this (and I haven't read the whole thread) but having just been involved in recording an album at 384Khz there is one simple answer; in that the higher resolution digital formats minimize quantization errors and quantization noise when editing, mixing, and mastering the recording.

    Edit: Actually 352.8 kHz as the person below pointed out.

    Also isn't it 'DXD' 384kHz? And I think it's 352.8kHz too ?!?!?!

    Developed for use in editing DSD programme material and found to sound quite nice in its own right.

    DSD is usually up in the MHz I thought?

    P.S. Some recordings can be found here:-

    Well done Sir!

    Having been in the studio myself many years ago, I can see these advantages in mixing! "BUT!" ~ in the final commercial stereo mix down for the domestic market, surely 44/16 is ample for anyone's ears? I mean, that's still twice the 20/20K human hearing limit! I have tried the higher ratings and always come back to 44/16 in the end; all the higher rates do is give me ear ache. In the good old (analogue) vinyl ONLY days we didn't worry about hertz and bits, that only started with digital.

    The timing difference between one peak (transient) of a 20kHz wave and the next is 0.00005 of a second (help me out here, as I've shown my arithmetic struggles sometime, that's 5 hundred thousands of a second? 5 pico seconds?), so whilst the human ear might be very sensitive to 'transients' they can all still be captured in a basic redbook recording.
    So it turns out that my maths is wrong but that it doesn't matter a great deal, it turns out that, thanks to the amazingness of Sampling Theorum any signal (within the selected bandwidth of half the sample rate) is perfectly recreated - the line between 3 sample points only has one solution. The practical impulse response of 16/44.1 is 55 picoseconds.

    I like to decide with my ears not a slide ruler or oscilloscope, don't understand the maths and physics much. LOL.

    Ears are the best tool and the only things that tell you how the sound is. Hi-Fi equipment can measure very well, yet still not sound right.
    It is impossible for anything digital to sound analogue, because it isn't analogue!

    Using spectroscopy.

    How might I measure your preferences?

    Ask you.

    With enough sample data and honest enough answers from you I'd probably start to be able to predict which ones you would like from their spectra.


    As for the other comments re maths, not understanding something it doesn't make it not true.
