B seems to be the lossless, the its in the gaps eh?
There is an easier way, in audacity just load the first few seconds into the spectrum analyzer, that is a dead give-away.
The files were intentionally compressed with different FLAC compression settings so that it wouldn't be immediately obvious which one was originally lossy. Otherwise, if both were compressed with the same settings the smaller file size would be the MP3 lossy version. Using different random compression settings for each eliminates that potential give-away.
B is the lossless.
I can't tell the difference, but alot of you could. I am impressed.
When I do get my music, I do try and shoot for 320 or lossless, as there really is not any reason to use 128. Space is cheap.
To me it seems that headphone amps have the same effect. The difference was so small if at all, I was never able to tell.
Quick back of the napkin calculation of odds of getting 14 out of 17 correct responses assuming null hypothesis (that responses on 2 choice test are purely random) says that the odds of this outcome is 0.0052. This clears the P < 0.05 significance by a mile. So assuming that all those 'b' responses were truly independent and not swayed by other responses, the conclusion to the hypothesis test of whether people can hear the difference between 128kbps and lossless files is - yes.
