Well, not exactly in BIAB. But the way BIAB works is just as I described. You don't have to 'see' it. If you really want to 'see' the difference, compare the files in a spectrum analyzer. You will definitely see a difference.

However - another thing that you can 'see' in BIAB is that you might notice a slight improvement in regeneration time, because now there is no need to uncompress the .WMA files first before loading the sound into RAM. In the early days of RealTracks, this time savings was noticeable, perhaps around 20%. Less so now. This, by the way, is why PG Music has a command to uncompress all the .WMA files. It doesn't change the sound - only the audiophile version does that - and it takes up 11 times more room, but loads like the audiophile version, which is slightly faster.

As far as hearing a difference, as I have written here innumerable times, it depends on your playback equipment, listening environment and how good your 'ears' are. Certain instruments are much easier to detect the differences, including but not limited to cymbals, acoustic guitar, and acoustic piano for starters.
