    It also depends on what you're listening on, computer speakers, headphones, or $5000 a pair studio monitors.

    I didn't do to well, was trying to guess based on the highs.

    I'm using a pretty good set of headphones connected to my phone but I'd argue that it doesn't make a whole lot of difference unless your speakers and DAC are completely crap.

    I took a recording class in college and we did something similar to this test.
    We used a rock box, the stereo in the control room and then the 5k monitor speakers.

    The song was "Jesus Built my Hotrod" and man what a difference with the 5k speakers, the stereo and the rock box (portable stereo) sounded the same to me.

    I wonder if the NPR test is really more of a testament to the labels mixing engineers than anything else.

    I couldn't detect any discernable difference. But, I am listening on a laptop.

    I think it might be. Some of the files sounded almost identical to me. Some were quite easy to make out, like Tom's Diner.

    Through the on board speakers? They won't do.

    No. I have some cheap Dell powered plug in speakers with a sub. They're better than the onboard speakers, but definitely not audiophile quality.

    Possibly a less conclusive test, without definition of "best". Uncompressed doesn't mean best. We add compression to IMPROVE the sonic qualities.

    I consistently chose the 128kb versions as best sound quality. That tells me I had good discrimination, and preferred the sonic quality associated with that sample rate. Without a very very extensive analysis of the phase content, waveform stability and overall frequency dependencies, its quite possible the lower sampling rate produces a more uniform response with less cancellation and destructive interference in content -ie, the superior sonic product. The last time I checked my hearing, I was able to discriminate to .35 Hz, and less than 2 cents for pitch. I forgot what dB levels I was able to detect, but it was in the 5% percentile.

    I listened on headphones and monitors and couldn't tell any difference at all. I do have a stinking cold, blocked sinuses and tinnitus...:eek:

    I had to re-listen several times. They are nearly indistinguishable, but I relied on the thicker sections with lots of content, and ability to still hear each instrument, and also the dynamics coming and going with loud-soft passages. I couldn't detect any high end or low end difference, and assumed the frequency range was the same. And I used closed headphones in a quiet environment.

    I haven’t done the test yet but a few weeks ago I tried Tidal since it streams at a higher rate. I remembered a test done similarly to the one mentioned above I did when I started to learn how to record so I figured it would be worth it for me.

    But nope.

    I’ll try the test but have low hopes.

    I used the same approach. The 4 ones that I managed to pick out the wav-file on all sounded wider and more airy to me. The other two were pretty much guesses, they all sounded the same to me.

    I tried tidal too but found very little or no difference. In many cases I even thought the lower quality alternative sounded better.

    I listened several times too and found them very similar. I too have a cold but my sinuses are OK, and no tinnitus.

    Have a Guinness and get better!

    No I can't. Reason? The bloody FireWire link to my audio interface has gone down again! :mad: I put in a new FireWire card a few months ago, and it's been fine until today. Now I can't get the audio back! :mad::mad::mad:

    Back in the 1980s, I could tell CD from Chrome cassette in a heartbeat. (CR02 has a slightly brighter top end, leading me to get them the wrong way round on first attempt. But even then, I was 'sorting them into two piles' correctly, just falling into the trap of thinking the brighter ones must be CD.)

    Can I do it now with MP3? I think so, but a chance would be a fine thing. :(

    I listened through crappy samsung earphones plugged to a laptop at the office, and marked 3/6.

    I think i should score higher if I listen on better equipment and environment.

    Personally my opinion is that the mp3 320 fairly good and not to different from a loseless codec to my ears. The thing about mp3s reputation is that it flipped the music market upside down... that pissed off a lot of people and in the process it degraded the way people get and listen to music. Maybe it deserves some of its bad rep, despite being a really cool engineering invention.
