Where there is a difference is that compressing an entire wav file with two stereo tracks and multiple instruments and vocals on it is a little bit different from what BiaB Realtracks do, which is to compress separated tracks with only one instrument on each.

Yes, there will still be differences as compared to fullscale PCM audio .wav format, but it seems that the largest difference found is in the high frequency content. There is a lot less of the kind of anomalies that rear their ugly head when the compression takes place over the entire single stereo multitracked or multi-instrument file.

So I'm speaking of a different double blind test anyway.
