Have a friend take a CD that you know well, rip a track to .wav & then convert it to .wma, best settings (I can not remember if RT are at the highest or not).

Make sure the playback levels are the SAME.

Then give it a causal listen to, say 3 times thru....can you tell the difference?

Now give it a focused, concentrated best headphone - earbud - speaker listen to, focusing on the High-Mid's to High End (5k to 15k area) & the Low Mid Punch (400Hz to 800Hz area) of the tracks....can you tell the difference?

A few years back I was challenged constantly about this, and got it right 80% of the time. The times I was wrong was either when the test was skewed (by accident or on purpose) or I was just flat out wrong.

I don't by into the double blind test 100% accurate debate, because everyone's ears changes every day, thus everyday the test will be different, just like the one I propose above.

Science is not the measure of art, and music is an art that, just like anything worth doing, has it's own intricacies that is more felt at times than can be measured.....

Anyway, if you can not hear the difference between the .wma and the .wav file during a casual listen, then neither can your audience.

And as usual this is a IMHO, YMMV, yada yada type of post, some will disagree, that's fine, it does not affect the results of my years of doing this! LOL
