I would like as many people as possible to participate, so that I can get an idea of whether this codec will be acceptable. The test will probably take about 1 hour.
If you would like to participate, you can download the samples here: http://www.mediafire.com/?foak1v87qqebbzd
In order to actually conduct the test, you will need to get foobar and the ABX comparator component.
Foobar: http://www.foobar2000.org/download
ABX Comparator: http://www.foobar2000.org/components/view/foo_abx
You can see a tutorial on how it works here: http://www.youtube.com/watch?v=jt7GyFW4hOI
Now, here is how you take the test.
In the zip file of the samples, you will see 2 folders, Test1 and Test2.
One of the folders contains the audio samples compressed with the Lame, and the other folder contains the samples compressed with the new codec which I am testing.
In order for me to know if the new codec is better than Lame, you will need to complete both tests.
In each of the two test folders, you will find 2 versions of 4 audio samples. The ones labeled 'A' are the original files, and the ones labeled 'B' are the compressed files.
Using the foobar abx comparator, you will compare the A & B files.
Please run 10 trials for each pair!
If you simply can't tell the difference between some samples, its ok to skip the 10 trials and just let me know that you couldn't tell the difference.
Once completed, please send me the results by Private Message. Posting your results here may influence others in their choices, so please don't do that.
The results that you send me should contain the score for each pair, and the percentage that it tells you. What you send me should probably look something like this:
(the following numbers are totally made up)
Test1
- Sample 1: 7/10 - 27.4%
- Sample 2: 3/10 - 90.2%
- Sample 3: Couldn't tell the difference
- Sample 4: Couldn't tell the difference
Test 2
- Sample 1: 4/10 - 82.8%
- Sample 2: 5/10 - 62.3%
- Sample 3: 7/10 - 17.2%
- Sample 4: Couldn't tell the difference
