download link for the 3 files has expired.
Also see 3 posts before this one..
If you want to get to know/hear the difference between 16 and 24 bit download the zip file: 16 vs 24 bit test.zip
If you want to know if you can really detect ultrasonic sounds (upto 40kHz in the original file and upto 21kHz in the 48 test file) download: 192-24 vs 48-24 test.zip
If you want to know the difference between hires 192/24 and 48/16 with MP3 320kbs CBR compression with 19kHz bandwidth download: 192-24 vs MP3 320 test.zip
You can download 1, 2 or all 3 tests if you want.
Once downloaded unpack (most can unzip files, if not I recommend 7-zip)
All the files are 192kHz/24 bit and equal in size and length.
Get familiar with the 2 files in each folder 'orig' and 'test'.
Once you are sure you know which differences to focus on.
The files ARE very measurably different so am not asking to detect differences between (very) similar files
.
Once you are familiarized you can try the blind test.
There are 5 files numbered 1 to 5
each number could be 'original' or 'test'.
In all tests BOTH files are used so there could be:
1 test and 4 original files
2 test and 3 original files
3 test and 2 original files
4 test and 1 original file
They are in random order and differ in order in each of the 3 tests
Orders were made using coin toss....
You can compare each test file to 'known' files and doesn't have to be done blind without the need to involve others.
Try to hear which of each test file is either 'original' or 'test' file.
Once you are sure you can either wait till I post the order of the test files or PM me (or e-mail me) in order to compare the results.
I will also make the bag of tricks known if you want to check if the files you actually listened to differ indeed.
No hidden agenda, I am not out to discredit people as you can do the test (or not) and keep the results for yourself or share them in a post or PM.
Note that this test cannot be used to prove to people how golden-eared one is for one simple reason.
Someone that knows about computers/audiophiles can very easily determine which file is 'tampered with' and which one is the original and post the results based on that thereby proving how good their ears are when the test set-up is revealed.
This test is only made for those who want to find out for themselves if they can hear 24bit vs 16bit, 48k vs 192k or hires vs MP3/320 .. in a 'blind' test one can do without someone else to help.
I recommend to use a DAc that can natively play 192/24 or higher.
Use speakers or headphones that have enough resolution.
If the DAc offers only support to 96/24 these DAC's can be used too and should be good enough to show the same differences between the files.
It is completely pointless to do the test on DAC's that can only do 44.1 and 48kHz or are only 16 bit as they won't be able to resolve the high-res files.
I hope you like the song I picked.
At least it has lots of 'audiophile' sounds/percussion in it , is DR16 (which is very dynamic) and is a real-life performance/recording of high quality.
If people are of the opinion they have music (in 192/24) that is much more evident or resolving I will gladly make a new test using an excerpt of this recording.
